general problems of the 2014 GMC Sierra 1500 - part 2

On making a turn at low speed, my engine has cut out completely. I had full loss of acceleration, power steering ,ac, radio. I put the truck in neutral and restart the engine to get to safety. This has occurred 3 times in the last 20 days. Twice in city traffic, once on the highway, turning off for gas. The "service steering assist" light appeared. I took the truck for a full diagnostic at a local electric repair shop, for $170. 00. The tech found nothing after hooking my truck to his computer. The day I retrieved my truck from the electrical shop, I stopped in walmart for groceries. My key fob would not lock or unlock my doors. I manually unlocked the truck to determine that the truck would not start at all. No panel/ interior lights, no response in ignition,no automatic unlocking, the truck was completely dead. Roadside service came to tow it, and the truck was jumpstarted from his battery pack. The key fob began to work, unlocking,etc. I towed the truck home. I have VIN checked my truck and there are none but I believe my vehicular failure refers to gm part 573 safety recall 17v-414 regarding the loss of eps. A secondary recall which may apply is gm# 14v26000 re steering linkages, tie rod assembly. As the "steer assist' alert was what I saw. I have the work invoice from the electrical shop, if needed.

Began running rough bad lifters. Also interior is beginning to rust. Hheadlights are terrible it aka nearly impossible to see.

I temporarily had no control over the vehicle causing me to have an accident. While driving down a residential street approaching a stop sign intersection I merged into the center of st to pass a trashcan and in the process of returning to my correct position on the road I suddenly had no steering. Panicking from the loss I pressed my brakes an attempt to bring vehicle to a stop but was unsuccessful because the tires began a slide once noticing the traction loss I proceeded to release brakes and reapply in hopes of gaining traction the brief relief from brakes caused the vehicle to regain traction and while I still have no control over steering, the vehicle jerks towards the right side of the road and the brakes being reapplied the vehicle continues to slide off pavement making contact with stop sign and telephone pole.

First instance: (this issue happened three times in one day before being able to be repaired) without warning the vehicle lost all power and the motor died while traveling at approx. 35mph for several seconds. When it powered back up everything was reset as if the battery had been disconnected. The dealership found a "loose ground wire" underneath the dashboard and attributed the occurrence to this. Second occurrence: (less than a month later and happened twice within a few minutes) while travelling on the expressway at approx. 70mph and again without warning the vehicle lost all power and the motor died for several seconds. When it powered back up everything was reset as if the battery had been disconnected. This happened again while exiting the highway just moments later at a more moderate speed, again with zero warning. Dealership now states the problem is with the positive battery terminal wire & harness.

The catalytic converter failed at 110,000 miles and the brake boost hydraulics failed to work properly at 115,000. The electronic stability control started acting erratically at 115,000 miles also.

The contact owns a 2014 GMC Sierra 1500. While driving approximately 70 mph, the vehicle slowed and the abs, brake, check engine, and other indicators illuminated. The brake pedal traveled to the floorboard. The vehicle was coasted to the side of the road and was later driven home. The vehicle was taken to the dealer, but the cause of the failure could not be diagnosed. The failure recurred. The manufacturer was made aware of the failure, but did not respond. The vehicle was not repaired. The failure mileage was approximately 29,000.

The contact owns a 2014 GMC Sierra 1500. While driving 25 mph and making a left or right turn, the vehicle jerked violently and caused the steering wheel to become erratic. The failure recurred numerous times. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 67,800.

Steering wheel springs/snaps (hard) in the opposite direction that the wheel is being turned and steering control is lost. When this does not shut the engine off, the only way to regain steering control is to restart the vehicle. When this does cause the engine to shut off the steering is restored with the restart. The stabili trak indicator appears just for an instant on the dic when this happens. Note: this is not the 'service stabili trak' indicator but more like stabili trak has been activated indicator. This happened first in reverse while backing into a parking spot. (three times in reverse). Then it started happening in drive, twice while pulling out from a stop sign and once while doing 15-20 mph turning onto a side street. The 15-20 mph turning instance caused the engine to shut off, steering became non existent for an instant and then very very heavy. I crossed the other lane of traffic and almost landed in the ditch. The truck has been at the dealership twice for a total of 14 days, both times 'cannot duplicate' was the result. No codes are being generated from these instances. Cause is unknown. Loose voltage or high resistance to grounds maybe. This has happened in hot and cold weather, running ac or heater or neither. There is no pattern. Please help.

The problem started while backing a trailer and turning. The stabiltrack light came on and the steering wheel jerked out of my hand. It happened a few more times and then the truck died. Later while driving the stabilitrack light would flash on and the dic would go black. The a. C. Would also go out and come back on. It would also do this when turning on the signal light or stepping on the brake pedal. I was in a parking lot today driving slowly and the st message came then the dic went black again. When I tried to turn the wheel it started jerking back and pulled out of my hand. It seems that shutting the truck off and restarting solves the problem for a day or two. This is a very unsafe issue and I have seen and read many complaints. I have been a huge fan of gm and all I have ever owned were gm vehicles, but this issue is making me wonder if I should have bought a Ford instead. It seems that gm is not worried about recalling because of this safety issue, which there are many complaining of the same thing, and my warranty is about to run out.

Vehicle will lose power and shut off while driving, while in reverse I have had the steering wheel ripped out of my hands. Random error messages on dic, random starting issues. Taken to shop multiple times, they cannot find an issue.
