2014 GMC Sierra 1500: adaptive cruise control problems

Filed Dec 24, 2020 · Electrical, Lights · 70,000 miles · NV

2014 gmc sierra 1500 4wd ~75k miles. Sometimes when I roll up my windows or use my blinker and it shuts off cruise control (hwy). And sometimes when I hit my breaks my headlights will dim (hwy, city streets, parking lots). When I'm turning slowly (in parking lots) the steeling will occasionally lock up and once it lost power entirely. My battery was tested at bigo and said it was fine. I've seen this online a lot for this truck and similar years, but no one seems to have a resolution. With so many incidents I'm shocked they don't have a fix or any idea what is wrong.

Owned truck for one year, bought used at dealership. Within 6 months, the service stablilitrack message popped up while on highway and power steering diminished. Cruise control would turn off when using the blinkers to change lanes. Put a new battery in and things worked well until yesterday when on the highway and the service stabilitrack message came back again when I used my turn signal to change lanes while using the cruise control. The cruise control also turned itself off. Went to park and the truck shut down for one second and seemed to reboot. It drove fine after that but scared the [xxx] out of me. Luckily no one was around. The headlights have also dimmed when pushing the brake pedal. I see there was a recall but I don't know if this truck had it fixed at that time or not. The website tells me there is only one open recall but for the brake system and this seems to be an electrical problem not brakes. I am contacting the dealership but I doubt they will have an answer and will want to charge me for something that appears, according to this site and others, to be a major issue for this vehicle model. *dl parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Intermittently, when applying the brakes to stop for a red light, the engine wants to keep the vehicle going at the same speed and fights the brake so the vehicle cannot stop. Shifting the gear shift into neutral allows the brakes to work but the engine RPM revs up to 2500 RPM for about 15 seconds before dropping to idle. If the driver didn't apply the brakes hard enough or shift into neutral, the vehicle would overpower the brakes and drive into anything ahead. Analogy: it acts as if the cruise control was on (and it's not) and tried to keep the same forward speed no matter the brake application. Dealer cannot reproduce the problem, no alert warning light. Some times, going at highway speed, taking foot off accelerator and expecting vehicle to start slowing down, it stays at same speed for about 15 seconds before dropping rpms. This has been happening, intermittently, for a few months.

Mark porter gm superstore in pomeroy, oh sold me a new truck with unresolved recalls in december 2014, one being gm recall 14192. The engine in my truck failed on january 1, 2015, and the recalls were disclosed to me when the truck was towed in for repair, approximately 2 weeks after purchase. The aforementioned safety recall is in reference to a potential transfer case selector malfunction. After repair of the recall, I had a malfunction of the transfer case selector, except it became stuck in 4 wheel drive, instead of shifting to neutral. I had also been experiencing issues with the cruise control, which I asked them to address while it was in there for the 4 wheel drive selector problem. The service dept reset the 4wd selector again, and told me that my cruise control issue was related to the 4wd issue. I still have issues with the cruise control, and have requested a buy back. It has been approximately 5 weeks since I informed them that I feel my vehicle is unsafe, and nobody has made any effort to help at all. I would like to return my vehicle for a full refund, as well as I would like to see the dealership fined for selling me a vehicle with an unresolved safety recall. I feel this is unacceptable on their behalf.
