“The check engine light came on, my gas tank needle went down to empty on a full tank of gas and will not come back up, and it stalls. While I was driving.”
NHTSA complaint #11404272, filed 2021-03, 210,702 miles“My 2008 Trailblazer is having a rough idling issue.. When I first start my vehicle it does not want to keep running. It doesnt want to move either. It is the throttle position sensor and it cost 300.00 to buy the part”
NHTSA complaint #10807375, filed 2015-11, 157,000 miles“For three weeks my fuel light denotes that I am on empty. I thought that I had forgotten to get some gas. But when I started to pay attention to the gas light, I noticed that, even when I filled up the gas tank, I was still getting that ringing sound that denotes 'empty'. I took my car to the dealership and they said that they would charge me about $460 to fix the problem, that an awful lot of money for a fuel light. What's up with this?”
NHTSA complaint #10252608, filed 2008-12, 57,300 miles“Smelled gas odor from rear of vehicle. Crawled under and found gas tank leak at the connection of filler pipe to tank/check valve. Understand this was known defect on earlier years and tanks wer covered by a special coverage plan 14423. Any extensions for later (2008) model years?”
NHTSA complaint #11073407, filed 2018-02, 38,000 miles“The fuel gauge is fluctuating from full to empty and the empty light comes on. It has occurred a few times now over the last few weeks. The issue has the potential to cause a stall condition, if the vehicle runs out of gas unknowingly due to this inaccurate gauge condition. I have been able to research some documented evidence of this known issue on NHTSA, but have not found any solution being offered by GM.”
