Example complaints

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

“The toe links on my vehicle are bad and needs to be replaced. They broke as I was driving. Almost caused me to lose control and almost wreck. Thankfully there were no other cars around. I see this is a recall for GMC’s but for some reason not my vin number. Not understanding why if I have the same problem on vehicles that were recalled.”

NHTSA complaint #11513919, filed 2023-03

“The contact owns a 2018 GMC Acadia. The contact stated that upon parking the vehicle and attempting to release the key from the ignition switch, the key seized inside the ignition switch. The contact stated that either the “Parking Assist” or the “Steering Assist” warning light was illuminated during the failures, and the A/C system became inoperable. The failure had occurred on several occasions. The vehicle was taken to the dealer, where it was diagnosed with Parking Assist and Steering Assist failures. The vehicle was repaired. The manufacturer was notified of the failure. …”
