STEERING
My Wife was driving at a low speed completing a right hand turn through an intersection and as she completed the turn the vehicle completely lost all steering. The vehicle ran up onto a curb but she was able to stop before she hit a poll. The vehicle was towed home and I found that there was no power to the steering wheel controls, the horn didn't work and there were Electronic Steering warnings. I also found that the steering wheel could spin freely like a top without any movement of the wheels. Upon examination in the engine compartment I found that the bottom of the steering shaft was completely disconnected and the single bolt that holds the 2 pieces together was missing. I took the vehicle to the local GMC dealership and they conformed that the bolt was missing and the shafts came apart which lead to the steering failure. The free movement of the steering wheel caused the internal malfunction of the steering wheel electronics. Prior to the steering failure there was no indications of any steering issues. The steering warning lights didn't come on until the steering failure. My Wife and children were about to get on the freeway when the failure occurred and could have led to a fatal accident if this failure occurred while she was driving on the freeway. I contacted GM and opened a case but was informed that they would not provide any assistance with the repair which is about $2900. I don't understand how GM would design a steering shaft that has a single point failure that could lead to a catastrophic failure. The vehicle has 120K miles and has never been in any accidents. I expect a basic safety feature such as the steering to never fail during operation. I will never purchase another GM vehicle and will tell as many people as I can about the potential failure.

ELECTRICAL SYSTEM
My "Service Trailer Brake System" messages comes on periodically for days at a time with and without my trailer. The loud chime rings consistently for the duration of the drive. It makes driving unbearable. When connecting my trailer to it, the brakes do not seem to function correctly when towing. This is very dangerous. I found out that a lot of my fellow GMC SUV drivers have the same problem.

EXTERIOR LIGHTING
I have had to replace both front and rear exterior lighting in past (3). Now my rear brake light is now out. This makes 3 exterior that I’ve had to complete replace. Went out suddenly. No way to replace bulbs, dealer reports Entire assembly needs replacing at cost of almost $1000. There has to be a design flaw that every exterior lighting has gone out for so many owners and has to be REPLACED. There should be a recall on this. This model has had so many costly issues.

POWER TRAIN
My GMC Yukon Denali xl has a defective transmission from the manufacturer thousands of other General Motors customers are experiencing the same issues since 2015 General Motors has still failed to issue a recall. This problem cause the truck to leap, lunges and sometimes accelerate as well as hard down shifts which causes sudden stops this also causing severe damage over time. There’s also defective paint peeling and fading from the manufacturer

POWER TRAIN:AUTOMATIC TRANSMISSION
My transmission has issues shifting between 1st and 2nd gear. It has for several years. I have brought it into the dealership several times. They fix a part but when I get the car back, it’s still experiencing the same problem. When Accelerating, the car jerks between 1st and 2nd gear right around 10 miles per hour. It is a hard jerk that feels like you’ve been hit from behind.

SERVICE BRAKES
brake pedal takes much more effort to push I was parking the car and thankfully was only going about 2 mph because I had to press the brakes with two feet to stop it from hitting the car in front of me. We just arrived from a 2 hour trip and this happened at the end of our trip. Lucky it wasn’t on the highway or with a pedestrian in front of me. No injuries

SERVICE BRAKES
The service brake assist warning message keeps appearing. Additionally, when the vehicle is completely stopped, but then you let off the brake to roll forward a little bit (such as at a stoplight), when you press the brake again it does not have stopping power. Must pump the brake several times as the vehicle rolls. This is particularly dangerous in downhill stops. It appears there is a safety recall on the power assist vacuum for brakes on 2015 GMC Yukon XL, but for some reason, my VIN is not included in the recall. I would like to know what it would take to include my VIN in the recall because it is the same year, make, and model.

Brake lights - left brake light works intermittently, and often does not work. 3rd brake light (top center) has quit working. Both are issues with cracks in the circuit board, which googling has shown to be a known issue. Faulty, poorly designed or constructed parts!

POWER TRAIN
1. When starting out for the day start yukon, wait about 30 sec for the system to do self check, put foot on brake, put in gear the yukon will jump forward sometimes and bang. 2. When driving and you are decreasing in speed, sometimes you will get a small increase in speed, then it will start slowing down, sometime easy or hard where it will push your body forward. 3. Driving time to merge with traffic, put your foot on the gas pushing down, the yukon will start to increase in speed, then stops responding, (just for a few seconds) then it will go fast and bang or just this is bad because the other cars are coming up fast, there have been times I had to goto the right again and get out of traffic because it took to long to go. I have complained about this many times the techs would look at it, stating there are bulletins out on this same issue, they would go though and reprogram the Trans, they would state drive it for 200 miles, and it should correct itself, and it would and be ok for a few months or longer, then start again take it back to dealer do the same thing, i ask them what's going to happen if i am out of warranty, then you will have to pay to have to reprograming its about $150.00. I stated why will i have to keep paying for this issue, if its not a good fix, its a band Aid fix..... So i was told by a tech take off the negtive battery cable for 30 mins, tis should help you out also. Now take it in for a oil change ask if there is any new updates, we will check for you , yes we see that your Trans temp sensor is bad and it will be $475.00 I stated wait i have been complaining about this for years, NOW I am Out of warranty I need to pay REALLY.... NO dont fix it yet, I am going to reach out to GM.

EXTERIOR LIGHTING, EXTERIOR LIGHTING:BRAKE LIGHTS
Breaks are faulty, lights continue to go out in the rear after only a year after purchase. I’ve read other complaints about these issues. could be wiring or electrical issue with the breaks. Engine sounds like a plane is about to take off, has had starting problems. Overall horrible vehicle. There are a lot of problems with the vehicle, the lights are extremely dangerous as person behind would not know if I’m stopping when they fail to work and can cause a serious accident. Engine is a major concern as well.
