Selected complaints filed with NHTSA by 2005 GMC Envoy XL 370 owners, lightly cleaned up (personal details are redacted by NHTSA).

I filled up my 2005 GMC Envoy XL slt when it had 71,000 miles. I had no previous fuel gauge issues. Started the vehicle and fuel gauge went to empty even though I had filled it completely. I don't have the money to repair so have been driving it for the past month and this has been a daily issue while driving. The fuel gauge fluctuates between empty and full and will stick on empty and the bell chimes constantly even when I just filled it up. I have no way of knowing exactly how much fuel is in there except to monitor miles driven and fill it back up more frequently. I feel this is a safety issue. What if my calculations are incorrect and my vehicle stalls on the highway. I have two young children and am afraid of a stall happening resulting in a crash. The fuel gauge is not working. I have no way of knowing exactly how much gas is in there. …

Faulty fuel gauge on 2005 GMC Envoy, slt. Everytime the tank is filled, the gauge in the instrument cluster reads empty - sometimes it will rise to about an eighth of a tank, but shortly thereafter, it will go right back to empty. This problem has persisted for over a year now. There are thousands of participants on online forums with the same problem for several various GM brands. The average cost to rectify the problem is well over $500.00. The problem not only affects recent model vehicles but, it appears to affect earlier GM model vehicles as well, some as old as 1998. The problem appears to be a known defect, as many people have taken their vehicles to mechanics and/or the dealership to have the problem addressed. Nothing has been done to rectify the problem nor provide a resolution to the problem. …

2005 GMC Envoy; the fuel gauge has been acting crazy lately, so I decided to research this matter on the internet, and have been finding more and more incidents where the gas gauge either stays on empty or fluctuates from empty back to full and eventually stops working. At appx. 46,000miles, my gas gauge started doing the same as previously stated, going from empty to full, and sporadically repeating this even if the fuel tank was fuel. The fuel gauge being at the empty level, but the tank is fuel, causes a constant alarm bell to go off every 10 seconds or so, everytime you get in the vehicle. I have been trying to find the fuel sensor to replace it, but it seems that you have to purchase the hole fuel pump assembly which runs around $400, and I am not going to replace it, if everyone that has a GMC Envoy or Chevy trailblazer are all having the same problems. …

Fuel gauge malfunction. I filled the tank of my vehicle, 2005 GMC Envoy XL, I ran out of gas going up an inclined level of a parking garage two stories underground during rush hour in d.c. I could have easily let my SUV run into the vehicle behind me but, I was fortunate to react quickly and avoid harm's way. The problem with gauge is it will read full when empty at times and; shortly thereafter, you have total failure of the gauge - it will no longer properly read or register how much gas one has in their fuel tank. I thought that this might be a limited problem to a few suvs manufactured by GMC but, after doing research of several car forums internet sites I discovered that there are thousands of people who have purchased a GM with the exact same problem - including some vehicles older than the year 2000. What recourse do we as consumers have , if any? …

I have a 2005 GMC Envoy. The gas gauge had started having problems at 60,000 miles. It completely stopped working at 77,000 to 80,000 miles. I bought the car used in 2008 with only 45,000 miles. My job has me on the highway a lot. I tried to estimate the miles. But this is very dangerous I have ran out of gas on highway 820 at 260 miles after filling up. I ran out on highway 30 at 320 miles. In the country on private government property with no one to be found at 150 miles, every time I completely filled the car up with gas before resetting the fuel gauge. I can not afford to get it fixed. I can not trade the car in. I am a single mother twith three children that has been blessed so far to run out with out them in the car. I did realize so many others were having the same problem.

The fuel sensor on my vehicle swings wildly from empty to full even when the fuel tank has just been filled. This results in the check engine light to constantly be on. I am unable to determine how much gas is in the car due to the faulty sensor. I have checked the internet and this appears to be a widespread problem that has been reported for years. I called GM and they told me that they have known about the problem and will cover 50% of the cost only if I take it to a GM dealer and that my portion of the cost would be between $500 - $600 dollars. They would not cover any of the cost if I take it to my local mechanic. This problem has been known by GM for years and they should have issued a complete recall to repair the defective part(s).

I have owned my 2005 Envoy XL since June of 2006. Once, I passed 36,000 miles, I started experience lots of issues with my vehicle. I started hearing a knocking noise in the rear when I would turn on the ac and the steering was off somewhat. I had the steering fixed for around $400 but the knocking was going to cost around the same amount. Less then 10,000 miles later, the knocking noise is more persistent and is related to issues with the fuel pump. My gas hand will move to empty when I fill the tank up and will not move forward for days at a time. Today, my kids are complaining about the ac not working in the second and third row seats. Everytime I turn the corner it seems as if there is another problem with my vehicle.

2005 GMC Envoy XL with 49000 miles fuel gauge not working properly, will show empty after filling up then show full. Gauge will then show 3/4 full then 1/2 full after only 10 to 20 miles. Before 100 miles gauge will drop down to empty fuel light will come on and beep. This will happen till tank empty, I never know how much fuel is in truck. I have read that it could be fuel cap, so I replaced it but no fix. I have run out of gas on highway a couple of times already. This problem has been the same through 20 fill ups.can you help,from what I have heard runs from 600 to 1000 dollars.

Gas gauge malfunctions on my 2005 GMC Envoy XL. Fuel level was at half a tank when I decided to top it off before a snowstorm hit. Gauge read full but once I started driving it started to decrease and noticed the remaining miles left were also decreasing until low fuel light came on. Put car in park and it started rising again. Drove and it would go up and down. Parked overnight and restarted the next day and gauge read low fuel and indicator light was on. Drove a little then gas level went to normal and started fluctuating. This has now happened for about a week and a half.

Problem with severe fluctuations of fuel gauge. Research shows your ongoing investigation # is dp10001. Upon filling tank to aprox. Tank the gauge suddenly started going wild and within 1 mile of driving the "check engine light" appeared. After investigating numerous on-line resources it is clear that this problem is not only limited to this vehicle but is a serious problem in the GM lineup. Dealership repair costs are estimated in the $800.00 to $1000.00 range. This is unacceptable for a problem that GM knows to exist yet refuses to take any unilateral action on.
