The fuel gage fluctuates from full to empty. You never know when your getting low on gas.

Hi, I have a problem with the gas meter on my gmc envoy 2006. It has 38,000 miles. The gas gauge shows that the gas tank is empty even though I fill it up. When I start the engine the gauge goes shows that the tank is full, after a few minutes of driving it goes all the way down to empty and I get the signal that the tank is empty. My concern is about if there is any recall on that because it only has 38,000 miles. I was also checking online and found a lot of complaints for the same problem. I believe gm should be responsible for this matter because it is a sign of a defected part. This problem started happening on january 30, 2016; my main concern is getting stuck in traffic and possibly get in an accident due to the gas gauge is misreading. Thank you for taking the time to read my complaint.

Voss chevrolet, dayton, ohio, returned my envoy to me on september 2, 2015 without repair of a dangerous malfunction threatening serious injury to me or others. It is a sudden unintended acceleration occurring over seven times sporadically from july thru august 2015 as I have slowed to a stop at a traffic intersection and also when pulling head -in to parking spaces. It can only be stopped by abruptly switching from drive gear to park or neutral. I have driven this vehicle for just over 5 years of a 12- year period while also driving my non-general motors vehicle. As well, I have driven a newly purchased vehicle since april 2014. I have owned many vehicles over the past 51 years. I bought the 2006 envoy from voss chevrolet as a certified vehicle,32,000 miles, in april 2010. Voss electronic monitoring confirmed the fact that the high speed acceleration actually occurred while braking, but they stated when their service person kept and drove the vehicle it did not occur. Gm (tac) advised them unintended acceleration was "impossible and the only answer" is that I must be using two- feet, holding the brake and accelerator down simultaneously. (the voss electronic camera monitor they had given me had shown an acceleration equivalent to ""80 miles per hour while braking occurred! That is also documented.) (despite never a need to use two feet, in this SUV the left foot always rests some distance away on a foot-rest near the driver's door). I do not falsify matters. My background is one of integrity and reaching factually supported and logical conclusions arising from professional demands of a 41-year career as an attorney recently retired as a federal judge.

Ignition switch failure at speed causing loss of power to fuel pump which ultimately meant loss of power to vehicle at freeway speeds. Was told by gm that there is no recall on this particular ignition switch at this time.
