problem #2

Dec 142016

Envoy XL SLT 4.2L

  • Automatic transmission
  • 170,000 miles


I am so sick of my 06 GMC Envoy XL. I truly give up. I had the Stabilitrak and Reduced Engine light come on my car for five months. I have replaced the steering wheel sensor, the throttle body, and had the relearn the idle thing done, to no avail. This makes my fourth time going to the dealer, because I thought they could fix it. I have always bought GM. If God blesses me with another opportunity to buy a car, it will NOT be a GM. It throws my car off. I've had to pull over and start the car over a thousand times. I've seen many forums online about this problem, but there is no recall? I've even called GM. I STILL HAD TO PAY MONEY. Resetting the computer has done absolutely nothing. Just wanted to rant, because besides giving me some of my money back (to the tune of a grand), what can I do?

Envoy XL Denali V6

  • Automatic transmission
  • 165,043 miles

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, 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.
