What owners report

The fuel level sensor is malfunctioning giving me erroneous high and low readings. I noticed in August 2011, GM issued a special coverage for this exact problem, however it was only good for 10 years or 120,000 miles. My Envoy is 11-1/2 years old, but only has approx. 87,500 miles on it. Seeing this is an obviously safety issue which has LED to at least 1 known accident, I would like to know if there is anyway that you can help me get GM to extend the coverage to my Envoy? My Envoy also recently had a special coverage initiated for the headlamp driver module (hdm). I was able to get that fixed because GM issued the coverage for a total of 12 years and 150,000 miles. So the precedent has been set to provide coverage for a vehicle my age. Any help that you could provide would be appreciated. Thank you. [redacted]

2007 Envoy · 88,000 miles · Feb 2019

My fuel gage suddenly stopped working on my 2007 GMC Envoy. It read that I had 1/4 tank left, so headed to the gas station on a city street. I turned the Envoy off, for about a 15 minute stop, and when I turned it back on, the gage said it was empty. I filled the tank, and it still said it was empty, and the light is on. About 25 miles later, the gage popped up to 1/4 tank , but quickly dropped back down to read as empty again. The light stays on now. All other gauges on the dashboard work properly. The check engine light also came on, and is still on. I made sure my gas cap was on properly, and it was. I just purchased this vehicle on 12-30-15, so I do not know if there were any previous issues . My 2007 Envoy had 61,061 miles on it when this occurred, on 3-4-16.

2006 Envoy · Delivery › Fuel pump · 270,000 miles · Oct 2021

At every fillup we can smell gas like there is a fuel leak. I had a shop do a fog test and they confirmed a leak "somewhere from the top of the tank". The tank would need to be dropped to visually inspect at a cost of $400-$500 just for the dropping of the tank. Then there would be added costs to repair whatever is causing the leak and smell of gas. After hearing that I came home to start my searching for recalls & safety notices to find that GM had a notice issued as well as the NHTSA, but it seems they cut the year off at 2004 & 120,000 miles. According to the thread below, it appears this was extended to vehicle under 150,000 miles which we are well under, but we don't have a 2002-2004 model. …
