Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving the Envoy at about 45 MPH, a warning light saying reduced engine power came on suddenly, the car dropped down to about 20 MPH, and that continues to occur. I can turn off and restart the car, but the problem returns within a minute after driving it again. I started investigating what that means online, and, as with anything else on the internet, I see many opinions, guesses, and possibilities. Could be a bad sensor, bad throttle control, bad wire connections, etc. But this much appears clear: (1) it is a GM problem, and a very, very common one. (2) it is a dangerous problem. …”
