NHTSA complaint #11621174

Owner complaint summary

1) The car suddenly brakes as to avoid a collision when there are no cars in the proximity of the vehicle (think about driving on an open road on a sunny day and the vehicle suddenly brakes without warning). 2) We have received notice of low oil shortly after oil changes which have been performed at the dealership. It has been communicated to us by the dealership that it is common for these vehicles to burn approximately four (4) quarts of oil over the course of 2,500 – 3,000 miles leaving approximately two (2) quarts of oil remaining. Required tow to the dealership. 3) We have received rear axle warning messages and heard beeping noises alerting of such on at least thirty (30) occasions. The dealer has not been able to diagnose what the issue is and says that the computer is not storing any codes. They have not attempted any repair after being taken in for service on three (3) separate occasions. 4) In the past few days, the vehicle has thrown many error codes on the dashboard display including the rear axle service, service transmission unable to shift, service driver assist system. 5) On Tuesday, October 15th, 2024 the vehicle again began throwing error codes. The engine failed to start and was towed to the dealer via GM Roadside. Required tow to the dealership. 6) A fuel pump part required replacement as fuel was not properly being delivered to the engine. Required tow to the dealership. Safey is at risk. We have three (3) children who regularly ride in the vehicle with us along with the safety of others on the road (especially sudden braking).
