1 Vehicle Speed Control problem

Failure Date: 03/14/2019

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.

2 Vehicle Speed Control problem

Failure Date: 02/08/2017

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.

4 Vehicle Speed Control problem

Failure Date: 08/23/2012

While traveling on the interstate this morning, the speed on my 2006 GMC Envoy dropped suddenly and I had to pull to the side the road where the car completely stopped. I notified onstar, who performed a diagnostic test and indicated there was an issue with the fuel delivery system. The car would start up again, but only momentarily and the engine would die again. I had it towed to my home and am contemplating what to do at this point in terms of repair. There was another issue just over 2 months ago when the fuel gauge was not working and it ran out of gas. No indicator light ever came on. There was at least 15 gallons of gas in the vehicle today, as I had just filled it up a few days ago and had not traveled far. I have filled it up every weekend since the indicator light incident. About 2 years ago, I had to replace other parts related to the fuel. . Possibly called a fuel regulator?? which was mounted to the gas tank. This occurred at 37,000 miles. I was denied an inspection sticker because of an issue with emissions and had to replace that part as well.

5 Vehicle Speed Control problem

The contact owns a 2006 GMC Envoy denali. The contact stated that while driving 35 mph, the check engine warning light illuminated and the engine stalled. The vehicle was repaired by the dealer who replaced the sensor in the throttle body. The manufacturer was notified of the failure who advised that there were no recalls and offered no further assistance. The failure mileage was 84,000 and the current mileage was 93,000.

6 Vehicle Speed Control problem

Failure Date: 08/01/2008

GMC Envoy xl - 2006 has powered down three times while driving on a major interstate at approximately 65 mph during rush hour traffic. No warning lights prior to the power down. The vehicle slows to 15 within about 60 seconds. The first time, in approximately 2008, I was able to pull over two lanes to the breakdown lane and the power came back on while I was still coasting. I was told by GMC that without the light on they couldn't do anything. The second time in early 2012, the same thing happened during rush hour - there was no breakdown lane. When I went to GMC the light went off. I was told that I had a useful life of the car and it was getting old (135,000) miles and I should replace it. They said they could not do anything. It happened again last week on the interstate. I brought my car to my regular mechanic, non GMC, who coordinated with another GMC dealer for me. They fixed some codes they said were a problem. It happened again after having the car for 2 days. They fixed it again. We don't know if it's really fixed. This is a huge problem. GMC has no idea what they need to do to fix this. I have not seen service bulletins that relate to this. Powering down to a speed below minimum speed on a major highway is very dangerous. I do not trust this vehicle and feel very unsafe in it. Somebody needs to do something about this.
