Summary: I request that NHTSA open an investigation into the performance/reliability of the fuel level sensor installed in model year 2006 GMC Envoy XL vehicles. The fuel tank level sensor is defective and could result in vehicle running out of fuel, stall, and being rear ended by another vehicle. This almost happened to me on New Jersey turnpike. I was under the impression that I still had a few gallons left after numerous times the fuel light came on and off and then going back to 1/4 full.

Fuel meter repeatedly incorrect on 2006 GMC Envoy. After filling the car, the fuel light will illuminate and the gas meter will read empty. Driving will cause the gas meter to bounce between 0 - full sporadically - sometimes stopping in the middle, at 1/4, 3/4, 1/2 tank. Always incorrect. Very dangerous. No idea where my fuel level is at any time.

Own a 2006 GMC Envoy with 40,000 miles.the sending unit in fuel tank is faulty. When you fill the tank it will say full and then it will read empty. It goes up and down but it usually reads empty and is never correct.

2006 GMC Envoy XL gas gauge reads empty after filling, then slowly moves up after driving but will continue to lose pressure until it reads empty and the light is on, then the check engine light came on.

I own a 2006 GMC Envoy XL. Approximately 1 month ago, the fuel gauge started showing empty when there was a full tank of gas. It would reset to the actual reading when I would turn the vehicle off and turn it back on. It would stay on the actual reading and then a minute later the dial would go down to empty. I've been driving the vehicle like this for a month. Now the fuel gauge will not function at all. It shows empty all the time even when there is a full tank of gas. I have no idea how much gas is in my tank and it is very frustrating. I have to do quite a bit of traveling due to my nature of employment and find it dangerous to drive with this type of defect. Currently, I have 81,000 miles and the warranty has expired. After some extensive research on the internet, there are thousands of other owners who have or who are having the same problem. I think GM should have a recall and fix this problem before someone gets hurt or worse. $800 is expensive for any family who has to pay out of pocket.

The contact owns a 2006 GMC Envoy. The contact stated the vehicle stalled due to lack of gasoline fuel despite that the fuel level gauge indicated that there was fuel in the vehicle. The contact stated that the needle would fluctuate back and forth between fuel levels. The contact believed there to be a problem with the fuel pump. The vehicle was not inspected or repaired. The failure and current mileage was 45,000. Updtated 2/17/11 updated 02/23/11

Fuel tank gauge sensor doesn't work properly. This defect could result in someone running out of gas and being stranded or may even cause the vehicle to stall or not start at all.

2006 GMC Envoy XL - fuel gage not functioning occasionally reads empty with service engine light on even after filling up. Appears common issue with this model. Vehicle running out of fuel without warning can lead to serious consequences especially on highway. With numerous filed complaints, unfavorable blogs documenting the issue and GM dealers / service well aware of the problem it is time for a repair of this manufacturer's problem.

Gas guage reads empty, even after filling tank. It sometimes fluctuates, but returns to empty with the warning light on and alarm sounding. This is a 2006 Envoy XL with 50,000 miles. I am greatly concerned about the vehicle running out of gas and being subsequently impacted from the rear, especially at highway speeds. I have read over 400 complaints online, affecting many vehicle years and models. When will action be taken to recall and replace the defective units? after bailing out GM with taxpayer dollars, I would expect that GM would follow the correct ethical course and both redesign and replace the unit in all the vehicle years affected; I believe an existing complaint already exists, complaint(DP10001)

Filled up 06 GMC Envoy with gasoline and gas gauge never made it to the fill line. Now the engine light is on and the gas gauge reads empty and the gas light is now on.very concerned with the number of complaints on this site and nothing has been done by GMC. All I drive is GMC vehicles and GMC should do the right thing for its loyal customers.

Faulty fuel tank sensor in my 2006 GMC Envoy. Filled my truck up only for the gas gauge to read empty. Then my check engine light came on! took it to the mechanic who told me the fuel tank sensor failed and he noted it a common problem in the Envoy. Its costing me $800 to fix this. I have done some web research and it indeed looks to be a common problem, I find this very disturbing.

The fuel tank level sensor is defective. This may result in vehicle running out of fuel, stall, being rear ended or stranded in harsh winter conditions.

2006 GMC Envoy XL --same problem here. It started acting up just after the warranty ran out (just under 40,000 miles)! check engine light is on because of the sensor and will not pass inspection because the light is "on" fill up tank write down mileage is getting old. Time for our stimulus from GM! do the right thing and recall the defective sensors. Fuel gauge always reads empty now --could run out of gas without knowledge anytime/anywhere.

I have a 2006 Envoy XL that has a faulty gas gauge. It shows empty most of the time. I have contacted onstar and let them run a diagnostic of the situation. They tell me that the computer will sense a low or empty fuel tank and shut the engine down as to not harm the engine. I have read a lot of blogs about this problem on a lot of Envoy and have seen no recalls on it. Can someone explain to me why not ? I don't want a $500 bill to fix their problem of a lot of Envoy. I guess they are waiting till some one gets killed to do that.

I have a 2006 GMC Envoy. The gas gauge has been sticking and not showing correct gas reading. Very frustrating and after research it seems to be a common problem. Too expensive to fix. There should be re-call. GMC will be losing a lot of business if they can't rectify this for people. What a shame!
