GM Wheel Lock-Up From Transmission Control Valve Defect

Posted on by

General Motors (GM) has announced a safety defect affecting the transmission control valve in certain Chevrolet, GMC, and Cadillac vehicles equipped with diesel engines. The issue involves excess wear on the transmission control valve, which could lead to a gradual loss of pressure. This defect has the potential to cause harsh shifting, and in rare cases, a momentary lock-up of the rear wheels.

The Affected Vehicle Models Are:

2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2020-2022 Chevrolet Silverado 1500
2020-2022 Chevrolet Silverado 2500
2020-2022 Chevrolet Silverado 3500
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2020-2022 GMC Sierra 1500
2020-2022 GMC Sierra 2500
2020-2022 GMC Sierra 3500
2021 GMC Yukon
2021 GMC Yukon XL

GM first became aware of this issue in June 2024 through the company’s Speak Up for Safety (SUFS) program, after a customer claimed that the rear wheels of a 2021 GMC Sierra 2500 HD pickup allegedly locked up while towing a trailer. The incident caused property damage to both the vehicle and the trailer. This report prompted GM to open a new investigation.

Previously, GM had already investigated the condition, finding that excessive wear in the transmission control valve could cause harsh downshifting and, in some cases, a momentary lock-up of the rear wheels. Earlier tests and analyses suggested that the lock-up was unlikely to lead to loss of vehicle control, and no accidents or injuries were reported at the time.

In July, the National Highway Traffic Safety Administration (NHTSA) notified GM that its Vehicle Owner Questionnaire (VOQ) monitoring process had flagged additional reports that could be related to this issue. GM’s investigators conducted an extensive analysis of these reports and reviewed comprehensive field data, identifying 1,888 field reports alleging a potential lock-up condition. Further examination revealed eleven specific incidents where the vehicles veered off the road, causing minor property damage. There were also three minor injuries reported, although none were linked to a collision.

Based on these findings, GM’s Safety Field Action Decision Authority (SFADA) decided in October to initiate a safety recall.

To address the defect, GM dealers will install updated transmission control module software. This software will monitor valve performance and detect signs of excess wear approximately 10,000 miles before a wheel lock-up condition could occur. If excess wear is detected, the software will limit the transmission to fifth gear, effectively preventing a wheel lock-up scenario, which typically happens during a downshift from eighth gear. Additionally, the vehicle’s instrument panel will display a service engine light and a reduced propulsion warning message to alert the driver. GM’s number for this recall is N242454440 and the NHTSA campaign number is 24V-797.

Porsche Taycan Potential Battery Fire

Posted on by

Certain Porsche Taycan models from 2021 to 2024 may face issues with their high-voltage batteries, specifically the potential for short circuits within the battery modules. These short circuits could result in thermal events, including the risk of overheating or even fires in extreme cases. The root cause of this issue has been traced back to potential manufacturing problems from the battery supplier, which, in rare instances, increase the likelihood of internal short circuits.

This latest recall builds on earlier recalls that were issued for similar battery-related problems, namely 23V-840 (manufacturer recall code APB5), 24V-215 (code ARA4), and 24V-217 (code ARA5). Porsche has been using data analytics and conducting hardware tests to better understand the extent of the issue. On September 23, 2024, the company determined that additional Taycan vehicles might be at risk due to potential battery defects, even though no confirmed data anomalies have been identified in these vehicles so far. As a result, Porsche launched a new recall with the identification codes ARB6 and ARB7.

Breakdown of ARB6 and ARB7 Recalls

  • ARB6: This recall covers a group of vehicles for which Porsche does not have enough data to determine whether there are issues with the high-voltage batteries. Since there isn’t sufficient information, Porsche is taking precautionary measures. Owners of vehicles in this group will receive a notification advising them to limit their battery’s charging capacity to a maximum of 80%. This is intended as a temporary solution while further analysis is conducted to either confirm the presence of battery anomalies or clear the vehicle of any issues. This interim step is designed to reduce the risk of thermal events while Porsche continues its investigation.
  • ARB7: In contrast, ARB7 applies to a set of vehicles for which Porsche has gathered sufficient battery data, and current diagnostics show no data anomalies in the high-voltage battery. As a result, there is no need to restrict battery charging for these vehicles to 80%. What sets this group apart is that these vehicles allow Porsche to continuously monitor the battery health via over-the-air updates. This real-time data monitoring enables Porsche to detect any future battery module issues quickly. If an anomaly is detected later, Porsche will notify owners, replace the affected battery module, and advise them to limit charging to 80% until the replacement is completed.

As part of this recall process, Porsche is implementing a series of steps to address the potential battery issues:

  • For ARB6 Vehicles: Owners are advised to cap their battery charging at 80% until a more permanent solution is available. This is purely a precautionary measure while Porsche continues to analyze the vehicles and gather more data on the potential risks.
  • For ARB7 Vehicles: Since Porsche already has access to these vehicles’ battery data via over-the-air diagnostics, there is no need for an 80% charging limit unless future data shows a problem. Porsche’s real-time monitoring will automatically detect any battery module anomalies. Should a problem arise, the company will issue a notification to the owner, and the affected battery modules will be replaced. In the meantime, Porsche will advise affected owners to limit charging to 80% as a safeguard.

For both ARB6 and ARB7, the final remedy will involve installing an advanced on-board diagnostic software on all affected vehicles. This software will be capable of detecting potential battery anomalies before they become serious. However, before this software is installed, Porsche will conduct an analysis of the battery modules in each vehicle. If the analysis shows that no problems are present, the software will be installed immediately. If the analysis detects any issues, Porsche will replace the faulty battery module(s) before proceeding with the installation of the diagnostic software.

Once the new on-board diagnostic software is installed, it will continuously monitor the vehicle’s high-voltage battery using advanced data analytics. If the software detects an anomaly in any of the battery modules, it will send a warning message to the vehicle’s head unit, alerting the driver. In this case, the battery’s charging capacity will be automatically limited in stages: first to 80%, and eventually to a lower limit, likely around 50%, depending on the severity of the detected anomaly. This stepwise reduction in charging capacity helps prevent thermal events and gives the driver time to seek service. If necessary, Porsche will replace the affected battery modules to restore the vehicle’s full functionality. Since the battery consists of multiple modules, it is possible that different modules could show issues at different times, requiring multiple replacements over the vehicle’s lifetime.

Porsche plans to roll out this advanced diagnostic software as the final remedy in the first quarter of 2025. In the meantime, dealers will be prepared to install interim software and address any battery concerns as they arise. Owners of affected vehicles will receive notification letters starting on November 29, 2024. These letters will provide detailed instructions on what steps to take next and how to proceed with repairs or updates.

The recall numbers for this issue are ARB6 and ARB7. Additionally, the National Highway Traffic Safety Administration (NHTSA) has assigned campaign numbers 24V-731 and 24V-732 to these recalls. These recalls build on and replace the earlier recalls 23V-840, 24V-215, and 24V-217, expanding the affected vehicle population as Porsche continues its investigation.

Jaguar Land Rover North America, LLC (Jaguar) are reaching out to the owners of specific 2019 Jaguar I-PACE vehicles regarding a significant safety concern involving the high-voltage battery. The issue, which could potentially cause the battery to overheat, has prompted a recall to ensure the safety of the vehicle owners.

This recall comes after a series of events beginning in July 2024, when Ford’s Critical Concern Review Group identified a problem related to a warranty report. The issue involved a fuel injector with a missing o-ring support disc, which could lead to fuel system malfunctions. Ford’s Supplier Technical Assistance team, in collaboration with the supplier, conducted an in-depth review of images taken during the production of all fuel injectors to pinpoint the parts that could be affected. They then compared these findings to vehicle production records to identify the specific vehicles at risk.

On August 16, 2024, Ford’s Field Review Committee evaluated the concern and decided to approve a field action to address the problem. Up to that date, Ford had identified 10 reports of vehicles with fuel injectors missing the crucial o-ring support disc. Fortunately, there have been no reports of fires, accidents, or injuries related to this condition. However, the potential risk was significant enough to warrant immediate action.

Jaguar is advising all affected vehicle owners to take precautionary measures until the recall repair is completed. Specifically, owners are urged to park and charge their vehicles outdoors and away from any structures. This precaution should continue for 30 days even after the repair has been completed, ensuring the safety of both the owners and their surroundings.

As an interim solution, Jaguar dealerships will update the software of the battery energy control module to help mitigate the risk. However, the final, long-term remedy for the issue is still being developed. Jaguar plans to send out official owner notification letters by October 18, 2024, providing detailed instructions on the next steps. For reference, Jaguar has assigned the recall number H514, and it has been registered with the National Highway Traffic Safety Administration (NHTSA) under the campaign number 24V-633.

It’s important to note that this isn’t the first recall related to this issue. The same vehicles were previously recalled under multiple recall numbers, including 24V-085 (H471), 23V-709 (H459), and 23V-369 (H441). If you own one of these vehicles, you will need to have the latest remedy performed, even if your vehicle has already undergone previous repairs for this issue.

Unexpected ABS Activation In 2024 Acura ZDX All-Wheel Drive Vehicles

Posted on by

In a concerning development for Acura ZDX All-Wheel Drive owners, a potentially dangerous issue has been identified within certain 2024 models. The problem, rooted in the vehicle’s anti-lock brake system (ABS), could lead to unexpected activation of the ABS, causing a release of brake pressure that significantly diminishes braking performance. This defect poses an increased risk of accidents, particularly during specific low-speed braking events.

The problem first came to light in July 2024 when Honda, Acura’s parent company, was notified by General Motors (GM) about the issue. GM had received reports of two minor accidents, both allegedly linked to a sudden loss of braking, which were suspected to be caused by a software glitch in the ABS. In addition to these accidents, GM also reported a field complaint regarding the issue, though no accident had occurred in that instance.

Honda quickly launched an investigation into the matter. Upon closer examination, it was discovered that the issue was indeed related to a defect in the anti-lock brake system. Specifically, during certain braking events at speeds below 25 mph on dry surfaces, the ABS may activate with undue sensitivity. If this occurs and a specific sequence of wheel movements follows, the ABS will continue to release brake pressure in the service brake system. The result is a dramatic reduction in stopping performance, or in some cases, a complete failure of the brakes, greatly increasing the risk of a crash.

After confirming the defect, Honda determined that it posed a significant safety risk and initiated a safety recall. The company has emphasized that, as of now, no warranty claims, field reports, or incidents involving injuries or crashes related to this defect have been reported in Acura vehicles.

Affected vehicle owners will be notified of the recall and instructed to perform an iN VIN status inquiry to verify if their vehicle is eligible for the update. This notification is crucial for ensuring that all potentially affected vehicles, including those in new or used vehicle inventories, are addressed promptly.

To resolve this issue, Acura will be updating the electronic brake control module software. This update will be delivered either through an over-the-air (OTA) update or by visiting an Acura dealership. The update is designed to correct the sensitivity of the ABS, preventing the unexpected release of brake pressure and restoring normal braking function.

Acura has designated this recall with the internal number UJE, while the National Highway Traffic Safety Administration (NHTSA) has assigned it the campaign number 24VC-614.

Owners of the 2024 Acura ZDX All-Wheel Drive are urged to check whether their vehicle is affected by this recall. If you own one of these vehicles, it’s important to respond to the recall notice and ensure that the necessary software update is performed as soon as possible. This proactive step will help avoid the risks associated with the ABS defect and ensure your vehicle operates safely.

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.

Steering Wheel Could Unexpectedly Turn

Posted on by

The secondary steering torque sensor may not be properly calibrated on certain 2018-2023 Ford Mustang, 2018-2020 Ford F-150, 2018-2021 Ford Expedition, and 2018-2021 Lincoln Navigator vehicles. These vehicles are equipped with electronic power assist steering (EPAS) gears, which were installed as replacement service parts and are now found to have potential calibration issues.

This issue came to light when Ford’s Critical Concern Review Group (CCRG) was alerted by the supplier about an assembly problem affecting certain steering gears. To thoroughly understand the extent of this problem, Ford’s CCRG conducted a detailed review that included examining supplier maintenance records, warranty reports, and vehicle testing data. The findings prompted Ford’s Field Review Committee to decide on issuing a recall to address the defect.

The defect report indicates that the electronic Power Assist Steering (EPAS) gears, which were sold as service parts, may have an incorrectly calibrated secondary digital torque sensor in the steering gear. Specifically, the polarity of this sensor may be inverted. If the primary steering torque sensor fails or develops a fault, and the secondary digital torque sensor’s polarity is inverted, the steering wheel could start oscillating without warning. This means the steering wheel might alternate between clockwise and counterclockwise movements when the driver attempts to steer, leading to unintended steering assist from the electronic power steering gear.

This oscillation poses a significant safety risk as it can make steering unpredictable and difficult to control, potentially leading to accidents. Recognizing the severity of this issue, Ford has taken measures to address it.

Ford dealers will update the Power Steering Control Module (PSCM) software in the affected vehicles to correct the calibration issue. This update is intended to ensure the proper functioning of the secondary torque sensor, thereby preventing the unintended steering oscillation.

Owner notification letters were mailed on August 5, 2024, to inform vehicle owners about the recall and the necessary steps to have their vehicles repaired. Ford has assigned this recall the number 24S45, and it is also registered under the National Highway Traffic Safety Administration (NHTSA) campaign number 24E-055.
