General Motors has decided that a problem affecting vehicle steering exists in certain 2021 Cadillac, Chevrolet and GMC trucks. GM opened an investigation into the condition after receiving a field report of loss of power steering assist in a 2021 GMC Yukon.

According to the defect report, diagnostic trouble code (DTC) data obtained from the vehicle indicated that the power steering system may contain a software error that causes loss of power steering assist at startup or while driving. Vehicle testing demonstrated that manual steering remained available without power assist, but increased steering effort was required, particularly at lower speeds. In most cases, the malfunction indicator light will display on the instrument panel and a warning chime will sound. The condition is typically self-corrected at the next ignition cycle.

Vehicles Affected Include
2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2021 GMC Yukon
2021 GMC Yukon XL

GM will update the software in the vehicles’ power steering module. Owners will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may schedule to have the updates performed at a GM dealer. A certain number of vehicles that were part of GM’s captured test fleet will require replacement of the steering gear motor kit in order to receive the updated software.

GM’s number for this recall is N212333900 and the NHTSA campaign number is 21V-455.

General Motors has decided that a defect relating to vehicle safety exists in certain 2021 model year Buick, Cadillac, Chevrolet and GMC vehicles.

In April 2021, a Problem Resolution and Tracking System (PRTS) issue was opened following validation testing for a future model year vehicles, where it was noted some conditions in which loss of communication with the sensing diagnostic module (SDM) did not illuminate the airbag malfunction indicator lamp. GM opened an investigation in May 2021. A review of field data showed 19 warranty claims possibly linked to this condition.

According to the defect report, a software problem exists in some of these vehicles which would cause a SDM communications fault to illuminate the airbag malfunction indicator lamp, but only on alternating ignition cycles. As a result, an SDM communications fault would not consistently illuminate the airbag light on every ignition cycle to indicate a problem to the driver.

A driver might not be warned of an SDM loss of communication fault which might indicate a problem with airbag deployment. If airbags do not deploy appropriately in a crash, there is an increased risk of injury.

Description of the Cause : The Communications Gateway Module, also referred to as the serial data gateway module, software does not correctly store data indicating loss of communication with the SDM.

Vehicles Affected Include
2021 Buick Envision
2021 Cadillac CT4
2021 Cadillac CT5
2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2021 Chevrolet Corvette
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2021 GMC Yukon
2021 GMC Yukon XL

GM dealers will correct the problem by updating the software for the communications gateway module. Owner notification letters are expected to be mailed in July 2021. GM’s number for this recall is N212338110 and the NHTSA campaign number is 21V-421.

General Motors has decided that a software defect exists in certain 2019-2020 Chevrolet 6500HD trucks. These vehicles have been manufactured with tires that have a maximum speed rating of 75mph (regular production option (RPO) codes XDV for the front tires and YAP for the rear tires) and engine control module software that limits the speed of the vehicle to 79 mph.

In December 2020, Navistar, informed GM that vehicles may have been built with maximum speed limitation calibrations that exceed tire maximum speed ratings. A GM engineering manager reported the issue to GM’s Speak Up For Safety (SUFS) program and preliminary information was collected regarding the issue. GM opened an investigation in February 2021, confirmed the speed limiting software in the ECM and the body control module (BCM) would allow vehicles to reach 79 mph, exceeding the 75 mph maximum speed rating of the tires. In May 2021, GM’s Safety and Field Action Decision Authority (SFADA) decided to conduct a safety recall.

Owners receiving notification letters will be asked to return to their dealers to have the software calibration for the engine control module (ECM) set to limit the vehicles speed so it will not exceed the speed rating of the tires. GM’s number for this recall is N202325530 and the NHTSA campaign number is 21V-346.

General Motors will be contacting owners of select 2017-2019 model year Chevrolet Bolt EVs previously repaired under National Highway Traffic and Safety Administration (NHTSA) campaign number 20V-701.

The problem began in October 2020 when the NHTSA started an investigation into owner complaints of battery fires while their Bolt EV was charging. To reduce the risk of fires, GM provided a temporary fix in which the the vehicle’s software was updated to limit it’s charge to 90% of the battery’s capacity.

As part of the final repair, dealers will use diagnostic tools to identify potential battery anomalies and replace battery module assemblies as necessary. The fix will also include the installation of advanced onboard diagnostic software that detects potential issues related to changes in battery module performance. Customers will need to visit their Chevrolet EV dealer to have the service procedure performed. Once the remedy procedure is completed, the dealer will remove the 90% state of charge limitation and return the battery to its previous 100% charging capability.

Customers of 2019 model year Chevrolet Bolt EVs will be able to have this fix performed starting on April 29 and customers who own 2017 and 2018 model year Bolt EVs will be eligible to have the remedy performed by the end of May. GM will be making this diagnostic software standard in the 2022 Bolt EV and EUV future electric vehicles. According to GM, if a problem is diagnosed, the software will warn the driver with an illuminated warning lamp on the gauge cluster and drivers would need to have the vehicle towed to a dealer for repairs.

General Motors has decided that a safety defect affecting airbags exists in certain 2010-2015 and 2017 Buick Enclave, 2010-2019 Chevrolet Traverse and 2011-2016 GMC Acadia vehicles.

According to the defect report, in October 2020, a third-party vehicle repair business contacted GM requesting repair assistance on a 2018 Buick Enclave. After removing the headliner to attempt to repair a sunroof water leak, the repair shop identified two fasteners that were not installed and one missing weld nut attaching the roof-rail airbag (RRAB) to the vehicle. Further investigation found that certain stampings associated with the connection of the roof rail airbag to the vehicles had damaged, out of position or missing weld nuts. Although the problem was identified during vehicle assembly, the repairs may have been missed or preformed incorrectly.

GM will notify owners, and dealers will inspect and, if necessary, realign or replace the weld nuts GM’s number for this recall is N202321200 and the NHTSA campaign number is 21V246.

Our lemon law client was excited about his new 2017 Chevrolet Cruze.

His first visit was at 747 miles on July 6, 2017. He was hearing a squeaky noise while driving his vehicle. The other problem that was presented at that visit was that while moving the driver side seat back it made a very loud noise. The Chevrolet authorized dealership had the vehicle for 20 days.

The next visit was on September 29th. His key FOB and the WiFi were both not working. The left front seat was making a rumbling noise when moving the seat from front or rear. He was also seeing the no key detected message coming on.

The 3rd visit was on May 8, 2018. His complaints at the time were the check engine light was on, the vehicle had a rough idle, he was hearing a metal tapping sound when driving at parking lot speeds and making turns which were coming from the rear of the vehicle. The Driver’s seat was also making a loud noise when moving the seat forwards or backwards.

On April 9, 2019 he brought the vehicle in again to the dealership. He was hearing a metallic rattle noise which appeared to be coming from behind the glove box. There was also a problem with the left front tire losing air and the passenger side rear tire losing air.

He was back at the dealership about 5 weeks later because both passenger side tires were losing air. The radio was also having some problems in that it would suddenly freeze.

July 23rd he brought the vehicle back to the Chevy dealership because it was pulling to the right and the suspension was feeling funny. He was also hearing a grinding noise from the right front wheel while driving. The key not detected message was coming on intermittently. The cabin air filter and air filter element needed to be replaced.

The last visit was about a week later. The driver’s side front seat back rest was falling when reclining and the key not detected message was displaying intermittently when trying to start the vehicle.

At this point our client was frustrated and called our office and spoke with California Lemon Law Attorney, Barry L. Edzant. Barry asked him to email us some documents to review. After signing a retainer agreement, a letter was sent to General Motors Corporation demanding that they buy back the 2017 Chevrolet Cruze under the California Lemon Law. GMC agreed to repurchase the vehicle and reimburse our client for his down payment, all monthly payments made, reimburse for registration and pay off the vehicle less a mileage deduction allowed under the law. They also paid all the attorney fees.

The Office of Defects Investigation (ODI) have opened an investigation into certain 2020-2021 Cadillac, Chevrolet, and GMC vehicles because of a problem affecting the airbag system. The ODI have received fifteen complaints from consumers who say that the air bag system in their GM vehicle malfunctioned. Nine complaints allege the illumination of an air bag malfunction indicator (MIL) and six crash incidents had significant frontal collision damage but the driver frontal air bags failed to deploy. All the complaints received involve either GM vehicles covered by GM Technical Service Bulletin (TSB) 21-NA-005 or CT4, CT5 and XT4 vehicles.

The TSB, issued in March 2021, addresses air bag MIL illumination accompanied by diagnostic trouble codes B0001-1B or B0012-0D. It also cites rust particles in the connection terminal interface of the driver air bag inflator as the cause of the air bag MIL illumination. Illumination of the air bag MIL under these circumstances may result in a non-deployment of the driver airbag during a frontal collision and increased risk of injury to the driver.

ODI is opening this preliminary investigation to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues.
