Cadillac Lyriq Defective Brake Performance

Posted on by

A potential safety issue has been identified in certain 2023-2024 Cadillac Lyriq all-wheel-drive vehicles. This defect could affect the vehicle’s braking performance, posing a risk to drivers and passengers.

The investigation into this issue began in May 2024, when General Motors (GM) received reports of two minor accidents allegedly caused by a sudden loss of braking. Both incidents were suspected to be linked to a software problem within the vehicles’ Anti-lock Braking System (ABS). In addition to these accidents, GM was also alerted to a separate field complaint that, while not resulting in an accident, seemed potentially related to the same problem.

To get to the bottom of the issue, GM’s investigation team gathered and analyzed field data from various sources. Despite the initial reports, they found no additional cases that could be connected to this defect. However, through careful analysis, they determined that the problem could indeed occur, but only in extremely rare situations. Specifically, the issue arises when a false ABS event occurs on a dry road at speeds under 25 mph. During this event, if a particular series of wheel movements takes place, the ABS system might continue to release brake pressure in the vehicle’s service brake system, even when it shouldn’t.

Fortunately, GM has confirmed that no injuries or fatalities have been associated with this condition. However, given the potential risk, GM’s Safety Field Action Decision Authority (SFADA) decided in August 2024 to issue a safety recall for the affected vehicles.

The defect report explains that under certain rare braking conditions on dry surfaces at speeds below 25 mph, the ABS may become overly sensitive. If the ABS falsely activates and a specific sequence of wheel movements occurs, the system might continue to release brake pressure, which can significantly reduce the effectiveness of the service brakes. This could lead to a reduction in stopping performance or even cause the brakes to become inoperative, thereby increasing the risk of a crash.

To address this issue, GM has made an update to the electronic brake control module software. This update can be installed either through an over-the-air (OTA) update or by visiting a GM dealership. If you own one of the affected vehicles, GM urges you to take action as soon as possible. The recall number for this issue is N242453471, and the National Highway Traffic Safety Administration (NHTSA) campaign number is 24V-598.

Brake Pressure Switch Short May Cause Fire In Chevy Trucks

Posted on by

General Motors. LLC (GM) has decided that a problem exists in certain 2019-2023 Chevrolet 4500HD, 5500HD, and 6500HD medium-duty trucks. The brake pressure sensor assembly could leak brake fluid into the brake pressure switch and cause an electrical short circuit.

GM opened an investigation in August 2022 following reports of a vehicle fire on a 2019 Chevrolet Silverado medium-duty truck. As part of that investigation, GM reviewed field data potentially related to the problem and warranty returned brake pressure sensors.

While a series of tests failed to duplicate the condition, in January, a warranty-returned sensor and harness were identified as exhibiting signs of heat damage. This part was subjected to more detailed analysis, including X-ray scans and a chemistry laboratory analysis. The results from these analyses revealed the presence of brake fluid past the diaphragm seal, into the brake pressure switch, and through the actual wire harness into the pump’s fuse circuit. An inspection of the returned components also revealed delamination of the corrosion-inhibiting sealant, which allowed slow seepage of the brake fluid past the diaphragm seal.

According to the defect report, a zinc-nickel plating and sealant used to inhibit corrosion within the pressure sensor assembly may cause delamination of the sealant which results in small fragments of sealer underneath the diaphragm during assembly which allows brake fluid to slowly seep past the seal and into the pressure switch. The brake fluid may seep into the sensor’s electrical components and short the brake pressure switch and the associated fuse. If brake fluid shorts the brake pressure switch and the fuse, the circuit can generate enough heat and could result in a fire. An under-hood fire may occur when the vehicle is off and possibly unattended.

Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the master cylinder pressure sensor and inspect the wire harness. If the harness is damaged, it will be replaced as well. Interim letters notifying owners of the safety risk are expected to be mailed on May 29, 2023. Second letters will be mailed once the remedy is available. GM’s number for this recall is N222375270 and the NHTSA campaign number is 23V-266.

We are still receiving inquiries concerning Chevy Bolts. GM continues to work on replacing the batteries in the 2017-2021 Bolts, but it seems as though progress has slowed dramatically in the replacement of the 2020 and 2021 vehicles. In the meantime, GM continues to sell 2022 and now 2023 with the new generation batteries, which of course begs the question as to why the batteries in the 2022 and 2023 Bolts are not first finding their way into the 2020 and 2021 Bolts. Unfortunately, we do not have an answer to this. We will continue to accept Chevy Bolt cases until every Bolt owner can be assured that their vehicle is safe for their family.

The Chevrolet Bolt was one of the first electric vehicles to gain mainstream popularity. It was marketed as an affordable and practical EV with a range of over 200 miles on a single charge. However, the Bolt has been plagued with battery problems that have affected its reliability and safety.

One of the main issues with the Bolt is the slow replacement of its battery. Unlike gasoline-powered cars, EV batteries are not interchangeable, and replacing them can take weeks or even months. This is because the process involves removing the entire battery pack, shipping it to a specialized facility, and replacing it with a new one. The slow replacement process has left many Bolt owners stranded without their cars for extended periods.

Despite these battery problems, GM is still manufacturing new Bolt vehicles. This has raised concerns among consumers about whether the company has fully addressed the underlying issues with Bolt’s battery. GM has released several recalls related to the battery problem, including 20V-701, 21V-560, and 21V-650. These recalls aim to fix the issue by updating Bolt’s software to prevent battery fires and reducing the charging capacity to prevent battery degradation.

However, the repeated problems with the Bolt’s battery have led many to question its reliability. If a car experiences the same problem repeatedly, it may be considered a “lemon.” A lemon is a car that has a substantial defect that cannot be fixed despite multiple repair attempts. In the case of the Bolt, repeated battery problems could mean that the car is defective and not fit for purpose.

If you own a Chevy Bolt and have experienced repeated battery problems, contact us at 1-888-395-3666 to explore your options. Lemon laws protect consumers from defective products and ensure that they receive compensation or a replacement vehicle if their car is a lemon.

In conclusion, the Chevy Bolt’s battery problems have affected its reliability and safety. The slow battery replacement process has left many owners stranded without their cars for extended periods. Despite several recalls, the repeated battery problems have raised concerns about the Bolt’s reliability and whether it is a lemon. If you own a Chevy Bolt and have experienced repeated battery problems, it is crucial to explore your options under the lemon law and protect your rights as a consumer.
