SERVICE BRAKES
While I was in line at the gas station to get gas, I moved up because the car I front of me had done so. After moving up a bit, I pressed my feet on the brake but the pedal was very stiff and the breaks did not hardly engage. I almost ran into the vehicle in front of me. This was very scary. So I called for a tow truck to pick me up but after a while they didn’t show. I started my car up to see if the the brakes engaged and they did. So I slowly and carefully drove myself to the GMC dealership in Southaven, MC which was 0.3 mile away from the gas station. The GMC dealership said that it was vacuum pump that was at fault and admitted it was a recall for this. But they said since my truck has already been serviced for this recall that I would have to pay to get it fixed. This is absolutely absurd. If the issue was not fixed properly in the first place, why would I be responsible for getting it fixed the second time?

POWER TRAIN
Transmission Code P0700 and P0796 ( pressure control) I was on the Interstate and my 2015 GMC YUKON SLT Engine locked up and shift down to 2nd gear. Causing other cars to almost hit me from behind and possibly causing an accident. I had to quickly veer off on the side of the road so that they wouldn’t hit the back of me. Immediately my engine light came on. Didn’t have this problem prior to the breakdown. Brought it to GMC dealership they told me my torque converter was bad along with Computer TCM and Valve body. They said I need a new transmission. My SUV have 132k miles. I called around at other transmission shops and they ALL said they are getting 3-4 GMC YUKONS in to fix a week and knew exactly what the problem was with SUV. They couldn’t understand why GMC wasn’t correcting the problem. Also, last year had to replace the Cam Shaft, Lifters and Catalytic Convertor that’s was $6000 now they tell me $5500 for Transmission. That’s $12000+ in repair in lease than 1.5 years. Never have I had this much major problem on a vehicle. This is a major safety issue especially on interstate.

STEERING, EXTERIOR LIGHTING
Both my tail lights have failed. Dealer wants insane amount of money for new ones, so I opened up the lights and there is an obvious design flaw in the lights, to me it seems intentional at worst, incompetent at best. I am an electrical engineer, and there is no reason they should put a friction connection in the LED power bar, it is a glaring design flaw. Also having steering assist issue at low speed which was an issue that was supposed to be fixed in a previous recall service, but it is still malfunctioning.

SERVICE BRAKES
Last week, the power brake assist began fading away intermittently at low speeds, and caught my wife off guard in a grocery store parking lot when she pulled into a parking space and the brakes were not available. She had to plant both feet on the brake pedal in a panic stop before crashing into the car parked in front of her, and has since never driven the vehicle. This is a danger, and is potentially life threatening.

POWER TRAIN
Transmission failure at 167,000 miles. Transmission failed during a 100 mile trip initially slipping and eventually would not engage. Vehicle traveled on I 26 and could have resulted in accident on this 80 mph interstate. This vehicle is typically driven by my wife. No warning and GM Onstar provided vehicle diagnostic check in days prior to failure with no issues. Technician advised this was the 3rd vehicle this month in his shop with 6L80e transmission failure and said they normally fail around 150,000 miles. This is a known failure on numerous general motors vehicles across the product line. Repair required replacement of 6l80e transmission with a factory rebuilt transmission. Cost $4,100.

ELECTRICAL SYSTEM
The problem initially started around August 19th when my daughter was driving the SUV. It started suddenly flashing multiple service problems ex trailer brake service, park assist service and stability track service. It started flashing them over and over every second and the engine would rev up then slow down which continued even after she was able to pull over and get it into park. It was terrifying for her. We had the vehicle towed to GMC. GMC felt the electrical problems were due to the fuse box so they replaced the entire fuse box and changed all the fuses. Last week, my daughter again was driving home on the highway and the vehicle started doing the same warning but also displayed several more warnings and the car was lurching forward and slowing down over and over again despite trying to maintain a safe speed. She was close to home and thankfully made it safely home. I drove the car the next morning a few miles to see what was going on and it started doing the same thing with alerts, servicing cycling through the dashboard and the speed and rpm kept revving up and slowing down, I could not maintain a steady slow speed as it seemed like the car was braking every few seconds so it kept lurching forward out of control. We had the car again towed to the same GMC. This time GMC changed out all the battery cables going to and from the batter itself. My husband picked up the car a few days later after being told the problem had been fixed. Within a couple miles of leaving the dealership (and thankfully before getting on the highway) the car started again with the lurching, revving and continuous flashing of a multitude of service alerts/failures. GMC had the car towed back to the service center where it has remained as they run more diagnostic tests. We are concerned that there is a serious electrical problem that they have been unable to figure out on this vehicle which has put each of us at serious safety risk when trying to drive it.

SERVICE BRAKES
Brakes are not stopping the vehicle on short distances as it should. They are doing a clicking kind of noise and can feel pulses in the brake pedal as though ABS are trying to activate. I know there is a recall out but is saying my 2015 is not listed yet is doing the same thing that is described in the recall.

EXTERIOR LIGHTING
Tail Lights don't work. Have seen several complaints about this problem. There is currently a lawsuit concerning this. GMC will only cover replacement if car has less than 72,000 miles. The replacement lights cost about $800 each. Having it looked at now. Fear that I will have to pay replacement costs.
