Example complaints

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

“Shortly after getting gas, the car will rev to 2-3rpm when lightly accelerating, and seem to run rough . Then, after coming to a stop at a traffic light, the car will auto stop and then shift into neutral. I can not shift back into drive without pushing the start/stop button to restart the car. It does not happen every time I get gas, but all 3 times it has happened have been after getting gas. The first 2 times it happened, I was told there was a recall, which was the cause, but this last time, there was no recall, and they said there were no error codes, so they do not know what is wrong. …”

“While at a stop sign at a busy intersection, pressed brake and tachometer went to off instead of auto-stop. Engine still on but pressing gas didn't do anything.. Transmission light went on. Had to push the start/stop button a few times before engine turned off and on again.”

NHTSA complaint #11330713, filed 2020-06, 24,400 miles

“The start stop feature caused a life threatening hesitation upon acceleration from a full stop at an intersection. Enclave does not offer any override for this option. There must be a firmware update provided by GM to allow it to be disabled!!! This is going to kill somebody!!!”

NHTSA complaint #11150026, filed 2018-11, 500 miles

“During normal commute, vehicle began bucking badly, would not accelerate and began rolling backwards. Check engine light illuminated. Shut vehicle down, restarted, and the problem seemed to clear. Brought vehicle to dealership, found codes p0011, p0014, p0021 and p0024 set. Dealership contacted GM, who acknowledged the issue but offered no fix. They are still studying the issue and have no resolution. Dealership cleared codes and released vehicle back to us. Issue may return at any time. …”

“My car starting sputtering on take off from stops, extremely dangerous if you’re trying to get out in traffic and keep up quickly from a stop. Then when I took it to get looked at it the mechanic said it needs a new transmission. Now my family is stuck because that’s our only vehicle big enough for our growing family. They’re was a check engine light that keeps coming on.”
