Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Traveling on interstate 57 during daytime hours. While cruising at 73 miles per hour in the right hand lane, the vehicle sputtered and lost all power. I coasted to a stop off the side of the road. I restarted the vehicle and everything seemed ok, so I continued on. A little later it sputtered again and started losing power. The power came back before it came to a complete stop. I called on star for a diagnostic check and they told me I had a fuel system problem and that if the car would run to continue that it was not a safety issue. …”
NHTSA complaint #10328071, filed 2010-04, 86,355 miles“A couple months ago it stalled, while my 17 year old daughter was driving it. There were no engine lights on. This happened to me a couple times and to my husband. It takes about 2-3 minutes before you can start it. The engine light will come on when it stalls, but goes off when started. Without the engine light on, there is no the code to find out what is wrong. One time it stalled and when started, the engine light stayed on.. My husband took it to the GM dealer and we were told it was the battery. We bought brand new battery and installed it. Same day the car would stall. …”
