A small number of 2021-2022 Chevrolet Corvette owners will be contacted by the manufacturer regarding a problem affecting the rear half shaft assemblies in their vehicles. According to the defect report, Some Corvettes may have a rear half-shaft assembly that is missing one or more ball bearings. If any ball bearings are missing, the half-shaft will eventually fail, resulting in a loss of propulsion.

In September 2021, a General Motors (GM) engineer carried out a warranty inspection of a rear half shaft recovered from a 2021 Chevrolet Corvette. The half shaft fractured and caused the vehicle to lose propulsion. Upon further inspection, it was found that the half shaft was missing two of six ball bearings. Follow-up, discussions with the supplier identified a potential failure in the inspection process that led to the miss-build. In October, the GM engineer submitted a report to GM’s Speak Up For Safety (SUFS) program and the supplier identified 19 vehicle identification numbers (VINs) containing half-shafts that may have been improperly inspected.

GM is not aware of any injuries or crashes related to this condition. In February, GM’s Safety and Field Action Decision Authority decided to conduct a safety recall for any 2021-2022 Chevrolet Corvette that may have received suspect rear half shaft assemblies.

Those receiving notices will be asked to return to their GM dealers to have the left and/or right rear half-shaft assemblies inspected and replaced as necessary. Owner notification letters are expected to be mailed in April. GM’s number for this recall is N212351320 and the NHTSA campaign number is 22V-091.

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.

Certain 2016 Mercedes Benz C300 4Matic vehicles could experience a loss of power steering assist. According to the defect report, an incorrect torque sensor control calculation may cause a software issue that could lead to temporary deactivation of the power steering assist. The problem will result in increased steering effort, a warning message in the instrument cluster, and an audible warning chime. Continue reading

The owner of a 2014 Jeep Grand Cherokee, bought in November 2013, started experiencing repeated problems with his SUV shortly after purchasing it. The first repair attempt was in December 2013 with an additional five more repair opportunities at his Jeep dealership. These problems included a defective transmission, suspension, and alignment; which made the Grand Cherokee difficult to drive. This is when the owner decided to call the Law Offices of Delsack & Associates, P.C. for advice. Continue reading

General Motors will be asking owners of certain 2015 Chevrolet Colorado and 2015 GMC Canyon trucks to return to a dealer to repair a problem affecting the drivers airbag. The defect was discovered during routine diagnostic testing in which a GM technician found an incorrect diagnostic trouble code in the vehicle. An investigation discovered that the airbag connections were incorrectly manufactured, reversing the deployment sequence and timing of the driver airbag stages. This condition will cause the driver airbags to not function as designed, increasing the chance of injury. Continue reading

BMW will be asking approximately nine thousand sedan, crossover, and roadster owners to return their vehicles to a manufacturer repair facility for a safety defect that could result in the loss of oil supply to the vacuum pump. Due to an insufficient interference fit, the seal disk in the camshaft could move during engine operation, potentially restricting or blocking the oil supply holes. Over time, the pump could fail resulting in loss of power assist braking and an increased chance of an accident. (Even with loss of assist, the service brake control is able to stop the vehicle because affected vehicles meet the applicable FMVSS pertaining to conditions in which there is a loss of power assist braking.)

Infiniti is alerting owners of certain 2013-2015 hybrid sedans of a safety defect with their vehicles transmission software. In the affected vehicles, the Engine Control Module (ECM) is designed to go into fail safe mode and partially close the electronic throttle chamber if it detects a signal interruption from either one of the two Throttle Position Sensors (TPS). A programming error could lead to the electronic throttle chamber gradually opening regardless of the throttle position, resulting in the acceleration of the vehicle. Although the acceleration can be overcome by normal application of the brakes, the issue could increase the risk of an accident. Continue reading

Volkswagen will be asking approximately one hundred thousand owners of certain 2013-2015 Audi A4 and S4 sedans and 2013-2015 Audi AllRoad crossovers, to return their vehicles to the manufacturer to have the airbag control software updated. During routine testing, the manufacturer identified a potential issue with the frontal airbag system deployment parameters which could result in the front airbags not deploying during a second impact, after the side airbags have been deployed. This problem could result in increased risk of injury to the vehicle occupants. Continue reading
