Recall 20V-668: Power Train

Reported Oct 29, 2020 · 194,105 vehicles affected · General Motors LLC

Problem: General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Cruze and Buick LaCrosse, 2018-2020 Chevrolet Equinox, Chevrolet Traverse and GMC Terrain, 2018 Chevrolet Malibu, 2019-2020 Buick Encore, Buick Enclave, Cadillac XT4, Chevrolet Blazer and GMC Acadia, and 2020 Cadillac XT6 vehicles.

The front sunroof shattered spontaneously while I was driving down a 4-lane highway at about 63 MPH. It sounded like an explosion or loud gunshot. I was not near any other vehicles or under any trees. Temperature outside was about 75 and I did not have on the AC at the time. Fortunately the shade was drawn so I was not showered in glass.

alternator failed approximately 2½ years earlier, and the alternator and battery were replaced. another alternator and battery installed the following year. * A pulley bolt broke while I was driving and was replaced. * I subsequently had problems with the serpentine belt squealing and producing a burning-rubber smell, and the belt was replaced.

After the belt installation, the battery light came on. correcting the belt restored charging to approximately 13.9 volts. Despite that, an intermittent squeak or squeal when…

The transmission failed when traveling on busy highway in Aiken, SC on [XXX]. The money spent for these cars with failed transmission design/construction and the safety risk to all traffic must be addressed by NHTSA. GM customer is horrific in there…

My vehicle has 72,000 miles and has experienced two A/C system failures within 60 days. The first Freon leak was repaired under a GM special warranty. Only two months later, the system failed again, and the dealership diagnosed a rear evaporator core leak requiring a $3,000 repair. This is not normal wear. GM has documented this defect in bulletins PIT5335, PIT5335A, and 16‑NA‑046, which describe…

2019 Buick Enclave (GM) w/ 29481 miles, consistently serviced and in excellent working order. In city traffic about 45-50MPH, no warning lights until total electrical/power failure - no power, no steering, no electrical/lights. Car is owned by [XXX] mother-in-law ([XXX]). Her daughter ([XXX]) was driving. Had [XXX] been driving, there would have been a wreck. [XXX] was able to coast into a corner gas station/garage. Buy next day mechanic was able to isolate failure to alternator. Since we performed the repair at the closest mechanic, I do not know what GM knows. I see on internet a high volume…
