“Brake vacum pump experienced a catastrophic failure. I was unable to step on the break because the break pedal was hard. I ran thru a red light. I was told the brake vacume pump shattered & pieces of metal went into my engine”
NHTSA complaint #11753572, filed 2026-07“My radio volume goes nuts and the controls go unresponsive, The unit brings the volume up to max I can not hear emergency crews if they are using the siren. This also creates a safety issues as now I am taking my eyes off the road to try and stop the problem. The infotainment system is failing yes the truck is available for inspection. I have taken video of the problem and sent it to the dealer. …”
NHTSA complaint #11439172, filed 2021-11“When I stop and try to turn key off it does not turn to off. Have to turn back on and try shifting neutral and back to park. Then try straightened wheel and eventually key will go to off position and take out key. Started few days ago intermittently and now more often. Mileage is 36317 so warranty if expired. I will not pay dealer for analysis since it should be covered under engine. Also have seen 100s of complaints with this online for 2016 thru 2019.”
NHTSA complaint #11518967, filed 2023-04“I am reporting a serious safety defect involving my 2021 Chevrolet vehicle. While driving, multiple warnings appeared including “Service Power Steering,” “Steering Assist is Reduced,” “Service ESC,” and “Service Battery Charging System.” The vehicle then lost steering assist, braking performance became unreliable, and it created a serious risk of crash. The vehicle later shut down completely and has remained inoperable. The failure appears electrical and affected multiple critical systems at once, suggesting a cascading system malfunction. …”
NHTSA complaint #11740930, filed 2026-05“Beginning at approximately 80,000 miles I began to notice I could not remove the key from the ignition switch at times. Turning the vehicle on and off, shifting repeatedly into park, turning the steering wheel and pressing the brake had no effect. I now have 90,000 miles and the problem occurs about half of the time when trying to exit the vehicle. It is dangerous to leave the vehicle with the key still in the switch. I called the dealership and they said they were familiar with the problem and if it was like others they had encountered, it would require changing out the shifter mechanism. …”
