The initial time (3/14) it occurred, I was out of town with my family, embarrassed to say the least. However, mainly uncomfortable, tired, and frustrated because my 87 years old dad was stranded for hours as well as my 66 years old sister who IS recovering from cancer. This problem was a serious problem because of our location. We had gone to get dinner and ice cream after getting ice cream we back in the vehicle for it would not start. I called 911 no police ever showed nor would even stop to assist. After 2 1/2 hours, we contacted a church member to find out about a mechanic in the area that could possibly come check it out. Another church member came to check it first, by now 3 hours have lapsed and the vehicle starts. After this it has happened on three (3) separate occasions with me (3/19, 3/20, & 3/21) but my mechanic said it happened with him 3 or 4 times while he was driving it to check it out and while it was sitting just running not being driven. I was on the interstate once, once driving, and once parked and it would not start. The times I was by myself once was on the interstate, another was going through an intersection, and once was in a high crime area where I felt very unsafe for my vehicle and myself. My mechanic replaced the crankshaft and camshaft sensors and the problem persists. I had a diagnostic test performed but was told the items listed on the test 'may' be the problem. I have also had a problem with it accelerating while driving as if the gas IS not distributing properly. It was as if it was choking up as if there was a clog. A dangerous place to be in traffic or going across a railroad track, which it has occurred several times with me. I actually was almost rear ended on the interstate.

Last night I noticed at a stop light that I did not have low beam headlights on. very disconcerting. after I made my turn to exit the busy street, the headlights did come back on. after researching the issue, it IS a known issue with gm. in fact, many cars were selectively recalled on this issue. mine was not. granted, my car IS 11 years old with 157,000 miles, I still believe gm at some point should have warned me of this serious and dangerous issue. it appears I can easily fix it myself with a $27 "module" from autozone. no issues on the repair and part. I just think highly irresponsible of gm to not notify me of the potential issue. shame on gm.

Takata recall I have had to make many repairs on this vehicle. However, now the lifters in the engine collapsed. The vehicle only has about 87,000 miles on it. This IS unacceptable. There have been many complaints about this vehicle and the lifters collapsing. We are a one income family and the repairs to this vehicle are astronomical. Well over 3500.00 dollars. This vehicle IS not drivable and has been sitting for a year now at my mechanics. The vehicle IS of no use to me and has become a huge paper weight now. The worst part IS I still owe on the vehicle too. Gm needs to take responsibility and do a recall on this vehicle for the afm lifters, or pay for the repairs to this vehicle. I will never buy another gm product again. Own up to your mistakes and take accountability for this problem. I am not the only one this has happened to. Very disappointed in this vehicle that IS suppose to be american made!!!!!!! Then you want to know why people are buying more foreign made cars. They seem to be more reliable than the gm products.

The vehicle will abruptly go from 70 mph to 30'S (semi-trailer closing in fast) and I can't do a thing about it!! Service stabilitrack has been a thorn while under warranty and persists to be a problem now that it IS out of warranty! From early on, <10,000 miles and over 10 times since, this vehicle had been in to two different dealers and the problem, though intermittent, still exists and IS a huge danger to me and my kids but I can't just go buy another car or trade this in like some people (including the car dealership managers) portray IS the best option when I should be able to get gm to fix the car or replace it when they can't seem to figure out why the problem persists. But that hasn't been the only problem: gear band broke twice on the transmission, had to have transmission rebuilt because of faulty radiator, and other issues however none of the problems remotely compare to having taken it in for service because of the repeated unexplained de-acceleration and loss of ability to make the car do anything except pull to the side of the road and give it ten minutes to stop having a "tantrum" of sorts while traffic whizzes by and thankfully didn't hit us (yet). Exterior / aesthetics, I love this vehicle but poor function and even worse service of problems. I've reported it to corporate but they don't care and despite it having had been into the dealership numerous times prior to end of warranty, now they just want me to start paying them for all these fixes that haven't fixed anything. Once I started paying for fixes and then started complaining that they aren't covering what they've never fixed; the manager had the nerve to say he'd pay for it out of his own pocket if he knew it would fix it ... Hello... Why should the consumer pay for it when the problem IS never really fixed.

While driving, in pitch black darkness on 6/10/2016 around 1:00 am, my headlights suddenly went off. The only way I could obtain lights was using the high beams. Low beams do not work and high beam only works in manual on/off mode. We checked the lamps and fuses. All are in excellent condition. I have no lights while driving or in park. the side view mirrors move on there own and at any time, while driving , in park and when the car IS not running. This has been going on since the door panel recall was repaired. The dealer has informed me that there IS no recall on that either. last year (2015) I had to replace the airbags (suspension) on both rear wheels. The car would drop down lower than any mid size car. Once started the bags would inflate but the car may drop at any give time while driving. Gm did not cover this cost and the dealer wanted over $1200.00 to repair. prior to that the gas gauge quit working. Which gm did cover the repair cost but I never received a recall. I just happened to be at the dealer for the driver door recall and mentioned it.

This morning, my wife was parking at one of our kid's schools when the transmission system failed to respond. she attempted to put the vehicle in park, but it would not initially. once the shifter would move forward, the vehicle died, and continued to roll forward even though the shifter was positioned as if in park. she had the presence of mind to let it roll until striking the parking spot cement bumper. she removed the key from the ignition, then attempted to restart the vehicle with no success and the shifter button would not depress. she panicked because of loosing control of the vehicle with so many small kids around and called me. I left work, and upon arrival attempted to troubleshoot what caused the incident. I started at the shifter, so I loosened all the covers around it, in case there was something binding the shifter. I actually did find several small items that had fallen in the compartment through the front edge of the center console cover assembly. removing these items still did not allow restarting of the vehicle. I then looked underneath the vehicle, and discovered that the linkage from the shifter to the transmission had separated. I manipulated the input lever at the transmission with my hand and noticed that it had movement in both directions, which meant the transmission was actually not in park. after positioning the input lever at the transmission to park, the vehicle did start. I shut the vehicle off and reconnected the separated linkage. I was shocked to see that the piece that maintains such an important linkage connected appears to be made from a plastic. to me this IS a major issue that can cause someone to potentially have a vehicle stuck in a movement causing gear, and due to a linkage separation have no way to properly turn the vehicle off (until it runs out of gas), to made from plastic. please look into this. *tr

Ran out of gas with the fuel gauge reading half full (vehicle had approx 50K mileage). After putting a couple of gallons in the tank went to the gas station and filled the tank. When the vehicle was started the gauge bounced to full and then to empty. It began bouncing up and down continuously, sometimes settling at half full or at empty. It continues to do this today (9/16/13) but mostly stays on empty with the fuel gauge light on all the time regardless of how much gas IS in the tank. We now use the trip odometer to gauge the distance we travel so we know when to refuel. We were told by our dealer that it was the fuel sensor and would cost around $600-$700 to repair. *tr

TL* the contact owns a 2006 GMC envoy denali. While driving approximately 60 mph, the electronic stability control and traction control warning indicators began to illuminate. Immediately there was a substantial reduction in the speed rate. The failure occurred repeatedly whenever the vehicle was in operation. On two separate occasions the engine stalled without prior warning and restarted after waiting a few moments. The vehicle was taken to an authorized dealer seven different times. The ecm was reprogrammed and there were no additional repairs performed on the vehicle. The manufacturer was notified of the constant malfunction. The approximate failure mileage was 67,000.

I own a 2006 envoy denali and last may 2010 I was driving down the a busy highway around 55 miles an hour and the truck just lost all power and completely shutdown. It took aleast three tries before I could get it started again. I was so scared that a tracker trailor would hit me from behind. It didn't do again for a week , and then it happened again. I brought the truck to the shop and the throttle body was replaced at about 65,000 miles. Now its a year later and I again was driving on the highway and the truck engine light came on and all power was lost. I put my hazards on but could only get the truck to about 15 miles an hour so that I could get out of harms way. I called GMC to make an complaint as it IS very rare to have to replace a throttle body every year. I take care of my truck and see no reason why it happening other than GMC defect. GMC did not help me and just said there were no recalls and that it was normal wear and tear. I no this to be untrue and I am very disappointed with GMC and will never buy the product again. I have had nothing but issues with this truck, and after looking into it there are several other envoy owners that are having the same problems as I am. I don't drive on the highway if I can help it at all, getting stuck in the middle lane with a truck that won't move IS way to scary. GMC should have to make it right and recall the truck and figure out why the throttle body fails. *tr

In february I was driving home with my 5 year old daughter on the thruway, when suddenly the car stopped working. I luckily pulled over to the shoulder but had to wait there in the dark, terrified that we would be hit from behind, as it was dark. Imagine my surprise when I found out the car was simply out of gas! The gas gauge did not read empty but that was the problem!! Since that time I have run out of gas several more occasions, once with 5 children in the car at night. GMC IS not issuing a recall and it needs to be done now!! This IS a safety issue not only for the driver of these vehicles with the faulty sensor, but other drivers on the road also. Something needs to be done. *tr

With no advance warning, the fuel gauge started reading empty immediately when tank was filled. Possibly related or not, the flap in the fuel filler neck disappeared about the same time the problem started. Once the problem began, the fuel light would come on when the car was started and would stay on constantly. the check engine light IS always on as well. As fuel level decreased sometimes the gauge would apparently read correctly (e.g. Below 3/4 tank). Stopping or starting sometimes caused the gauge to fluctuate; often the gauge goes up and down several times a minute. over the last eight months the condition has worsened and the gauge often reads empty, with occasional swings up to approximately correct level (estimate based on miles driven since filling tank). However, the gauge never went below 1/8 tank, even though it was less than two gallons from empty in a 24-gallon tank. *tr

On may 10, 2011 the rear spoiler (with third brake light) flew off the back of my 2006 GMC envoy denali XL shortly after entering the highway. Lucky for me it was crushed by a passing tractor trailer instead of hitting someone's windshield. GMC said that since my SUV was 6 years old and over 100K miles I "should expect " these kind of problems. On july 24, 2011 shortly after entering the highway the entire liftgate window pulled away from the vehicle. I am about to open another complaint with GMC, but expect little help from them. Apparently the window and spoiler are both attached with double sided tape on this model year.a definite design flaw. It in my opinion IS a hazard to anyone driving behind one of these vehicles and should be recalled and the windows and spoilers "bolted" into place. *tr

The Office of Defects Investigation has received 668 complaints alleging inaccurate fuel gauge reading while driving in model year 2005-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Saab 9-7x vehicles.Of the 668 complaints, 58 incidents were alleged to result in a vehicle stall.Of the 58 stalling incidents, 43 complaints reported stalling because the fuel level reading indicated more fuel availability than what is actually in the fuel tank. One complaint alleged a vehicle crash after the vehicle stalled while exiting the interstate, became disabled, and was struck from behind.Summarily, the complaints show an apparent increasing trend, with most complaints received within the past year.A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.
