Automotive News – California Lemon Law blog

Toyota Motor Engineering & Manufacturing has announced a safety recall affecting certain 2022–2026 Toyota, Lexus, and Subaru vehicles equipped with a Panoramic View Monitor (PVM) system. A software error in the Parking Assist ECU — the electronic control unit responsible for displaying the rearview image — may cause the camera image to freeze or fail to display when the vehicle is placed in reverse. This issue means the affected vehicles do not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 111 for rear visibility.

What’s Causing the Problem?

The Parking Assist ECU software can experience two types of malfunctions:

Rearview image freezing: The image may freeze for up to 1.8 seconds if the vehicle is shifted into reverse within 0.7 to 2.6 seconds after ignition is turned on.
Rearview image not displaying: If the vehicle’s power is turned off during a brief data-writing process within the first 12.5 seconds after startup, the camera’s alignment data can become corrupted, preventing the image from displaying during the next ignition cycle.

These failures may occur under specific timing conditions and could increase the risk of an accident during backing maneuvers, especially if a pedestrian or object is behind the vehicle.

Timeline of Discovery

Between April 2024 and December 2024, Toyota engineers discovered the issue while reviewing software used in Japan-spec models. Bench testing confirmed that interruptions during image processing or data writing could cause temporary or complete loss of the rearview image. Subsequent testing through October 2025 confirmed that the same software error could affect global models, including those sold in the U.S. On October 24, 2025, Toyota decided to issue a safety recall.

Recall and Remedy Information

Dealers will update the parking assist software. Interim notification letters alerting owners of the safety risk are expected to be mailed December 16, 2025. Additional letters will be sent once the final software remedy is available.

The recall identification numbers are as follows:

Toyota: 25TB13 and 25LB06
Subaru: WRE25
NHTSA Campaign Number: 25V-744

What Owners Should Do

If you own one of the affected Toyota, Lexus, or Subaru models, until the software is updated, owners should exercise extra caution when backing up and verify surroundings visually.

If you drive a Cadillac Escalade, Chevrolet Tahoe, Suburban, Silverado 1500, GMC Yukon, or Sierra 1500, you may have already seen a Check Engine Light related to a coolant control valve problem.
Many 2021–2023 GM vehicles—especially those equipped with the 3.0L Duramax diesel (LM2 or LZ0)—have been affected by failures of the engine coolant control valve, sometimes called the engine coolant flow control valve.

This part plays a crucial role in regulating coolant flow to help the engine maintain proper operating temperature. When it fails or sticks, it can cause check-engine lights, overheating, and even high-speed radiator fan operation after the engine is turned off.

What the Issue Is

The engine coolant control valve manages how coolant circulates through the radiator and engine. When it fails, owners often report one or more of these diagnostic trouble codes (DTCs):

P1098 – Coolant Control Valve Performance (common on 3.0L Duramax models; fans may run at high speed even after the key is off)
P26BB / P2B60 – Coolant Flow Control Valve Position/Learn Faults

These codes can trigger the Check Engine Light (MIL) and may cause excessive fan noise or poor temperature regulation.

Vehicles Involved

GM lists the following vehicles as potentially affected:

2021–2023: Cadillac Escalade, Chevrolet Tahoe / Suburban, GMC Yukon / Yukon XL
2021–2022: Chevrolet Silverado 1500, GMC Sierra 1500

The issue is most prevalent in vehicles with the 3.0L Duramax diesel engine (LM2 or LZ0), but can appear in some gasoline variants as well.

What GM Told Dealers to Do

General Motors has released several Technical Service Bulletins (TSBs) and Preliminary Information (PI) documents to guide technicians:

22-NA-082 (April 2022) – Software programming update for vehicles displaying P1098 / P26BB / P2B60 codes.
PIP5791A (January 2022) – Directs technicians to command the valve open and closed multiple times to verify function before replacement.
Earlier PI (2019 → carried forward) – Replace the valve and perform a relearn if previous codes were logged and diagnostics confirm failure.
21-NA-271 (August 2023) – Advises checking for kinked cooling hoses that can cause similar fault codes before replacing the valve.

Special Coverage Program for 3.0L Duramax Models

In September 2025, GM announced a Special Coverage Program for the coolant control valve affecting certain 3.0L Duramax models.

Coverage up to 15 years / 150,000 miles (240,000 km) from the vehicle’s in-service date
Applies to Silverado 1500, Sierra 1500, and full-size SUVs equipped with 3.0L Duramax engines
Covers replacement of the coolant control valve and related programming if diagnostics confirm failure.
Program IDs: N252508340 and N252508341

What Owners Should Do

Get the codes read – Look specifically for P1098, P26BB, or P2B60.
Visit your GM dealer – Mention TSB 22-NA-082 and Special Coverage N252508340/N252508341.
Ask for a diagnostic and repair under warranty coverage if applicable.

California Lemon Law: Repeated Coolant Valve Problems Could Mean Your Vehicle Is a Lemon

If your GM SUV or truck has been in the shop multiple times for the repeated issues—or has been out of service for an extended period due to repeated repairs—you may have additional protection under the California Lemon Law (formally the Song-Beverly Consumer Warranty Act).

When Lemon Law Might Apply

You may qualify if:

The vehicle is still under the manufacturer’s warranty (including extended “special coverage” programs).
The dealer has attempted several repairs for the same problem without success.
The issue substantially impairs the vehicle’s use, value, or safety (for example, repeated overheating or engine cooling failure).
The vehicle has spent a significant number of days in the shop for warranty-related repairs.

If those conditions apply, California law may require GM to repurchase or replace your vehicle.

How to Take Action

Keep records of all service visits, repair orders, and communication with your dealer.
Request a copy of your vehicle’s repair history and diagnostic codes.
Consult a California Lemon Law attorney or consumer-protection advocate if your issue persists after repeated repairs.

(Tip: Lemon Law claims can often be handled at no cost to the consumer—attorney fees are typically paid by the manufacturer if you prevail.)

Certain model-year 2020-2025 Jeep Wrangler 4xe and 2022-2026 Jeep Grand Cherokee 4xe vehicles were manufactured with high-voltage (HV) battery packs that may contain defective cells. The defect can lead the battery to internally fail and potentially cause a vehicle fire – whether the vehicle is parked or driving.

What’s the problem?

On July 3, 2025, the manufacturer’s technical safety organization opened an investigation after reports of fires originating in the HV battery packs of these plug-in hybrid vehicles – including vehicles that had already undergone the earlier remedy under Recall ID 95B (NHTSA ID 24V-720).
The battery supplier Samsung SDI obtained a pack from a vehicle that had experienced a fire with cells manufactured outside the original recall’s scope. They found the fire was caused by the same defect identified under 95B and are working to identify additional causal factors.
As of October 13, 2025:
- 9 fires reported in vehicles which had already had the 95B software remedy applied.
- 10 fires reported in vehicles whose cells were outside the original 95B scope.
- 19 customer-assistance records, 0 warranty claims, and 19 field reports tied to this issue (dates from Jan 27 to Sept 2, 2025).
- 1 injury and no confirmed accidents tied to this issue.
On October 24, 2025, the manufacturer determined there is a defect affecting motor vehicle safety in all affected vehicles.
The manufacturer states that in rare cases, a battery pack may contain cells with separator damage which, combined with other complex interactions within the cell, may lead to a fire.
A key interim safety measure: risk is lower when the battery charge level is low or depleted, and higher when the battery is fully or highly charged.
Owner advice: refrain from recharging the vehicle, and park away from structures or other vehicles until the final remedy is available.
The recall campaign number is 68C (NHTSA campaign number 25V-741) and even vehicles previously recalled under 24V-720 or 23V-787 will need the new remedy.

Affected vehicles

Model year 2020-2025 Jeep Wrangler 4xe
Model year 2022-2026 Jeep Grand Cherokee 4xe

What should owners do now?

Minimize risk until fixed:
- Avoid charging the plug-in-hybrid battery.
- Park the vehicle outdoors or away from other vehicles/structures (such as garages) when practicable.
- Try to keep the battery’s state of charge as low as is reasonable for your use.
Wait for the remedy: The final repair or battery replacement is under development. Interim notification letters are expected to be mailed starting December 2, 2025, with additional letters once the remedy is ready.
Follow dealer instructions: Once the remedy is available, schedule service promptly. The remedy may include software updates to the battery management/control module plus potentially a full HV battery pack replacement.
Stay informed: Keep track of recall updates and announcements.

Why this matters: safety & resale considerations

A fire originating from a plug-in hybrid’s high-voltage battery is a rare but serious risk: it can pose danger to occupants, first-responders, and bystanders, and damage property.
Even if your vehicle hasn’t shown signs of the defect, being part of the recall means you should treat it as a potential risk and act accordingly.
From a resale/ownership value perspective, vehicles under open safety recalls can be harder to sell or may need disclosure depending on local laws. Completing the remedy promptly is beneficial for overall vehicle value and peace of mind.

Bottom line

If you own a 2020-2025 Jeep Wrangler 4xe or a 2022-2026 Jeep Grand Cherokee 4xe, this is a recall you cannot ignore. While the risk may only affect a minority of vehicles, the potential consequence is serious. Until the permanent fix is installed, follow the safety advice strictly: no recharging, park away from buildings, and monitor for dealer communications. Once the remedy becomes available, book the service as soon as possible. Your safety – and the safety of others around your vehicle – depends on it.

BMW and Toyota have announced a voluntary safety recall affecting certain 2019–2022 BMW models and 2020–2022 Toyota Supra vehicles due to a potential fire risk involving the engine starter relay. The issue arises when water makes contact with the relay, which over time may corrode and compromise the electrical connection. While corrosion can make it difficult or impossible to start the engine, in more severe cases it can cause the relay to short-circuit and overheat. This overheating poses a significant fire hazard, as a thermal event could occur not only while the vehicle is being driven but also when it is parked with the ignition off.

BMW launched an engineering investigation in July 2024 after reports of thermal events in certain vehicles. Over the following year, engineers analyzed field cases, conducted parts tear-downs, and tested water ingress scenarios in an attempt to replicate the failure. Although no single cause was definitively confirmed, BMW identified production periods that may be at risk. On September 16, 2025, the automaker initiated a recall. Toyota conducted its own review of records and confirmed no U.S. reports of Supra incidents to date, but vehicles remain included in the recall as a precaution.

Owners of affected vehicles are strongly advised to park outdoors and away from buildings until repairs are complete. Dealers will address the issue by replacing the engine starter at no cost to customers. Interim recall notices will begin mailing on November 14, 2025, with a follow-up notice sent once replacement parts are available. The recall is listed under NHTSA Campaign Number 25V-636.

Affected Vehicles Include:

2019–2021 BMW 330i
2021–2022 BMW 430i
2021–2022 BMW 430i Convertible
2020–2022 BMW 530i
2020–2022 BMW X3
2020–2022 BMW X4
2019–2022 BMW Z4

If you own one of these vehicles, stay alert for recall notifications, and in the meantime, take the precaution of parking your vehicle outside until the remedy is performed.

If you drive a 2020 or 2021 Ford Super Duty F-250, F-350, or F-450, there’s a new recall you should know about. Ford has confirmed a steering defect that could cause you to suddenly lose control of your truck while driving.

And here’s the bigger issue: these trucks already have a long history of recalls. If your Super Duty keeps going back to the dealership for repairs, it may be more than just bad luck — your truck could be a lemon.

What’s the Problem?

The recall centers on the steering column upper shaft. In certain trucks, the part doesn’t meet Ford’s own strength requirements. That means it can actually separate while driving, causing you to lose the ability to steer.

Safety Risk: Loss of steering control makes a crash much more likely.
No Warning Signs: There are no dashboard messages or alerts — the failure can happen without warning.
Affected Trucks: Ford believes the defect affects trucks built at the Kentucky Truck Plant before October 1, 2020.

How Ford is Handling the Recall

Ford has issued recall number 25S94 (NHTSA 25V-626). Here’s what they’re telling owners:

Notices in the Mail: Letters started going out in October 2025 to warn owners.
Dealer Inspections: Dealers will check your steering column.
- If it fails inspection → the part will be replaced.
- If it passes → it will be modified to improve durability.
Final Fix: A long-term repair solution is expected by December 2025.

Ford Super Duty: Too Many Recalls?

Unfortunately, this isn’t the first time Super Duty owners have faced recalls. The 2020–2021 lineup has been hit with recalls for:

Driveshaft separations
Brake system problems
Electrical issues

When you add the steering shaft defect to the list, it paints a troubling picture. For owners, these repeated issues can mean frustration, downtime, and serious safety worries.

Could Your Truck Be a Lemon?

Here’s the bottom line: If you’ve had to bring your F-250, F-350, or F-450 back to the dealer again and again for serious repairs, you may not just have a bad truck — you may have a lemon.

Lemon Law Basics: If a defect affects your truck’s safety, value, or reliability, and the manufacturer can’t fix it after a reasonable number of tries, you may qualify for a buyback, replacement, or cash settlement.
Why Steering Defects Matter: Because steering is critical to safe driving, repeated failures or incomplete fixes could make your case even stronger.

What Should You Do Now?

Keep Records: Save every repair order, recall notice, and warranty claim. Documentation is key if you ever need to pursue a claim.
Pay Attention to Repeat Repairs: If you’ve had the same issue fixed more than once, or your truck keeps going back to the dealer, you may have lemon law rights.
Get Help if Needed: Don’t wait until you’re out of patience (or warranty). Talk to a lemon law professional if you suspect your Super Duty qualifies.

FAQ: Ford Super Duty Steering Recall & Lemon Law

Q: Is it safe to drive my truck before the repair?
A: Because there are no warning signs before the steering defect happens, it’s risky to keep driving an affected truck. Schedule a dealer inspection as soon as possible.

Q: What if the dealer already repaired my steering issue once, but the problem came back?
A: If the same issue keeps happening after repairs, that’s a red flag. Repeated failures may qualify your truck as a lemon under state or federal law.

Q: How many repairs does it take before my Ford is considered a lemon?
A: It depends on your state. In many states, two or more failed repair attempts for a serious safety issue (like steering) may be enough. In others, it may take three or four attempts.

Q: Can I get a buyback or replacement if my truck is a lemon?
A: Yes. Lemon laws can entitle you to a buyback of your vehicle or a replacement truck, if the manufacturer can’t fix the defect after a reasonable number of tries.

Q: Do I need a lawyer to file a lemon law claim?
A: While not required, most lemon law cases are easier with legal help. Many lemon law attorneys work on a no-cost-to-you basis, since the law requires the manufacturer to pay legal fees if you win.

Final Thoughts

The 2020–2021 Ford Super Duty trucks are built to tackle tough jobs, but repeated recalls and a dangerous steering defect have many owners concerned. If your F-250, F-350, or F-450 is spending more time in the shop than on the road, don’t ignore it. Your truck may qualify as a lemon, and knowing your rights could help you get the compensation or replacement you deserve.

General Motors (GM) has confirmed a serious safety defect affecting certain 2019–2024 Chevrolet Silverado Medium Duty trucks. This issue involves the brake pressure sensor assembly, which may allow brake fluid to leak into the electrical components of the brake pressure switch. Over time, the defect can lead to short circuits, loss of brake system function, and even under hood fires, creating a significant risk of property damage and personal injury.

What Models Are Affected?

The following Chevrolet Silverado Medium Duty trucks are included in this safety defect:

2019 Chevrolet 6500
2019–2024 Chevrolet Silverado 4500
2019–2021, 2023–2024 Chevrolet Silverado 5500
2019, 2021–2024 Chevrolet Silverado 6500

Trucks produced before 2019 use a different brake sensor design and are not affected. Certain 2024 Silverado Medium Duty models built with a brake switch wire harness that includes silicone sealant are also excluded.

Why This Is a Safety Concern

If brake fluid leaks past the diaphragm seal into the electrical portion of the brake pressure sensor:

The switch and fuse can short circuit.
The circuit may generate excessive heat, leading to a fire risk.
A fire can occur even when the vehicle is parked and unattended.

This is not only a performance issue but a direct safety hazard for owners and the public.

Chronology of Events Leading to the Defect Finding

The journey to identifying this defect spans several years, beginning with earlier issues and continuing into 2025:

April 13, 2023 – GM issued NHTSA Recall 23V-266 addressing zinc sealant fragmentation in brake pressure sensors that could cause brake fluid leaks and under hood fires.
October 11, 2024 – GM’s quality team received a report of unintended brake pump activation in a 2023 Silverado Medium Duty truck that was not part of the earlier recall. The issue was escalated through the Speak Up For Safety (SUFS) program.
November 24, 2024 – GM opened a formal investigation after discovering brake fluid in the wiring harness of the newer sensor design.
December 18, 2024 – Another field report surfaced involving a 2021 Silverado truck already repaired under the 23V-266 campaign. GM’s analysis confirmed fluid intrusion.
January 2025 – Additional warranty-returned parts tested positive for brake fluid contamination in the harness.
March 3, 2025 – GM and International Motors partnered with Akron Rubber Development Lab (ARDL) for material analysis.
April 24, 2025 – Testing revealed that the rubber diaphragm was degrading due to the supplier’s use of an unauthorized chemical that reacted with brake fluid.
April 30, 2025 – GM identified one confirmed fire among 160 reports and began deeper field analysis.
May 28, 2025 – GM inspected the affected vehicle and concluded the fire was linked to the defect.
June 5, 2025 – GM’s Safety Field Action Decision Authority (SFADA) determined a safety defect existed in 2019–2024 Silverado Medium Duty trucks.

The Cause of the Safety Defect

Investigations revealed that a supplier used an unauthorized chemical in the rubber diaphragm of the brake pressure sensor assembly. This material degraded when exposed to brake fluid, allowing leaks into the sensor’s electrical system and creating the potential for fires.

Warning Signs Owners May See

Drivers may notice a “Service Brake System” warning light on the dashboard as the defect develops. GM advises that vehicles should be parked outdoors and away from buildings until the problem is corrected.

The Fix for Silverado Owners

GM’s remedy involves replacing the brake pressure switch wire harness with an improved design.

Interim owner notifications were mailed on July 29, 2025.
A second notification will be sent once parts are fully available.
Vehicles that were previously repaired under Recall 23V-266 will also require the updated repair.

GM has assigned this campaign number N242482680, and the NHTSA campaign number is 25V-390.
