Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Not safety, but GM recalled 2021Trailblazers to replace Evap Purge Pumps on vehicles showing check engine light resulting in bad purge pump diagnosis. Why only Trailblazers? I recently had to replace one on my 2021Envision at 37,588 miles after my check engine light came on. Fortunately I bought the extended insurance when I purchased my new vehicle and only paid the $100 deductible. Otherwise it would have cost me $404. If they knew of problems for that year, why not send out letters to other owners of GM vehicles? Thank you. …”

NHTSA complaint #11593096, filed 2024-06

“I think it may be either fuel propulsion system or it maybe something electrical. I don’t really know. It is available for inspection at this time as it has been at the car dealer repair shop for about a month. My safety is put at risk because about seven or eight out of 10 times that I attempt to start the vehicle, it will turn over by pushing the button, but will not start. I work until past dark many nights and my vehicle not starting is a big safety issue. The dealer said they reproduced it, but they have not been able to reproduce it again. …”

“My vehicle's motor stopped without any warning in the middle lane of a busy freeway. I put the emergency flashers on but when I tried to restart the motor it overrode the flashers, causing a semi truck to just miss hitting me. The transmission went into Park mode and since this car is electronic shifting it would not let me put it in to neutral when the motor is not running . People stopped to help me push the car off the road but we could not get it into neutral. Very DANGEROUS situation to be stuck in a center lane on a busy freeway. …”

“Driving at 45 mph the vehicle stopped running in traffic. Able to get off road and vehicle would not start. Engine turned over but did not fire. Waited about 10 min. while on phone with dealer and tried again. It started. Able to drive approx. 2 miles to dealer. Dealer says Fuel pump control module is bad. This is a dangerous situation.”

NHTSA complaint #11516960, filed 2023-04

“The contact owns a 2021 Buick Envision. The contact stated that while operating the vehicle, the contact heard a popping sound coming from the front end of the vehicle, and the vehicle became difficult to steer. The vehicle was taken to the local dealer who determined that the front driver’s and passenger’s side ball joints, and control arms were faulty and needed to be replaced. The vehicle was repaired but the failure reoccurred, and the control arms were replaced a second time. …”
