The sunroof of my 2015 GMC Yukon spontaneously shattered while driving down the highway at normal speed with a few normal sized vehicles and no overpasses nearby.

Air conditioner has failed for the third time in 18 months we've owned this vehicle. First repair 18 months ago resulted in "defective air conditioning lines" that were leaking, and was replaced by dealership (covered by aftermarket extended warranty). Second failure occurred June 2018, and same dealership stated compressor developed cracks and had to be replaced (fortunately still under aftermarket extended warranty). Now, beginning of November 2018, system has failed for a third time and in less than 5 months from the latest "repair", and unfortunately my extended aftermarket warranty has expired. I can understand a system failure once, have a difficult time with a second failure of the same system within 3 years, but question the dealership's ability to diagnose and fix a problem after a third failure in as many years of the same system. Absolutely love the vehicle itself, but questioning GM's reliability and customer service. I purchased a new escalade and loaded Silverado from this dealership new and had a few minor problems with those vehicles that the dealership fixed. After Y ears of owning those, purchased a newer model escalade and had several problems that seemed unusual for the age of the vehicle. I've had my current Yukon in the dealership service center four times in the 22 months I've owned it, and have been disappointed in the apparent downturn in GM reliability and willingness to stand behind their cars. In addition to the ac problem, have almost simultaneously encountered a passenger side led tail light failure, which at an approximate $750 repair means that on a 3 year old vehicle, I apparently need to budget $250 per year to ensure my tail lights work. Again, love the ride and handling of this vehicle, but since reliability appears to be an issue with GM, may have to begin looking at another brand of vehicle that is more reliable.

On July 13 of 2018 ac in my vehicle started to blow hot air, I was with my 3 year old, during this day it was 98 degrees out, my husband took the car to repair shop and they found a leak in the condenser, apperantly this is a known problem for many GM vehicle with 5.3 L V8 engine from 2014 and up, when we called local GM dealers they were aware of the ac problems on these cars, we were told that ac lines develop a crack and freon leaks or ac condenser starts leaking freon and in our case it's a condenser, after doing a research on the internet and reading on the GM forums many owners have these leaks due to bad design of ac components, it's obvious that GM should issue S recall because too many vehicles have same issue, and since our warranty has expired 6,000 miles ago we have to pay over $1000 for a repair, I hope your organization will do something about this problem, this should be a call for a recall.

Air conditioner condenser went out and it cost $944 on a vehicle that is only 3 years old and has only 65000 miles on it.

GM knows they have bad air conditioner condenser in 2015-2016 models. Yet still no recall done. Many complaints and nothing being done about it. New vehicles and vehicles just out of warranty. This is there problem, so much parts are on continous backorder. These are $50,00 vehicles and I should not be stuck with this. I am contacting the better business bureau and having the other 6 cases I know of as well

Air conditioner condenser gave out in the heat of the summer on a Yukon denali with 42,000 miles. I have had no air conditioning in 90 plus degree heat

- Michigan City, IN, USA

Had 30,000 miles and my steering colum was making popping noise. The dealership tried to just repair the bearings but it only worked for 2 weeks. They had to replace the whole steering colum. Brakes are squeaking for no reason had les schwann check them and still can't figure it out. My A/C now quit working. Struts in hatch also had to be replaced and passenger window molding is coming off.

A/C condenser leaking

- Ridgewood, NJ, USA

The air conditioner condenser failed. The part is on backorder and I have no air conditioning for an undetermined amount of time. No eta on the part and they will replace the part with the same faulty model. No loaner car, no airconditioning.

- Snohomish, WA, USA

The air conditioner condenser failed 1st week of June 2017 and the part is not available any where in the country. The vehicle is dangerous to drive when it rains because the windows fog over and are unable to clear with air system,

- Sycamore, IL, USA

Ac quit working & dealer said it's a bad condenser, which part is unavailable due to national back order. Can't tell me when they can get part to fix. Obviously this is a major defect on GM behalf & they're doing nothing about it. Not even a recall!

- Conway, SC, USA

My A/C started blowing hot air a few weeks ago. I took it in to my GMC service department, and they advised me it was the condenser that needs to be replaced, however that part is on back order indefinitely. I have since spoke with several people with vehicles like mine who have also had this same result with their A/C condenser. I would like this matter reviewed as an official recall.

- San Antonio, TX, USA

Ac is not working. Only hot air blows out. Dealer is telling us that the compressor is out and is commonly out for GM products from this year. The part is back ordered with no date available that it will be available. Apparently it is being redesigned. We have been told it may be months. Summer heat is coming as early as this week. With 4 children, I find it unsafe to have such a hot car. 17 people at our dealer alone are waiting for the same part. Please get GM to fix the issue.

- Mundelein, IL, USA

The vehicle has leaked water in the seams of the back driver side since the initial purchase. It has been repaired nine times by two different dealerships and it still leaks. The vehicle now contains a high moisture reading and was tested by a mold specialist and determined to have mold. The vehicle is currently with the dealership.

Window appliqus on both sides of vehicle became loose and were flapping while driving. This was concurrent with a very noisy cabin, likened to the sound of a window being open while traveling at highway speeds. These appliques were previously replaced by dealer after incidentally being found loose. The noisy environment in cabin is very loud and distracting, causing driver and passengers to get headaches and causing driver to become distracted.

Our 2015 Yukon XL denali has been in for repair service for 41 days since purchased new 3/23/15. The car has stalled while in motion with my wife and three daughters in the vehicle twice and been unresponsive to throttle input 3 additional times. The stall occurred once while turning left across traffic and another time while turning right and merging with traffic! the problem is intermittent and GMC has never been able to replicate it. They have given us the shoulder shrug, "I don't know what to tell you, we can't replicate it" line, so here are your keys. No warning indicators, no signs it may happen, and no way to pull up the issue with their diagnostics...huge safety concern and each time they have handed us the keys back after 7 days (their standard allotted time to have a loaner out) without any proactive escalation to find root cause or concern for my family's safety. The last time we took it in, they had it for 8 days and could not replicate the issue. We signed our service paperwork and I escalated to the service manager before leaving. After telling him we would be pursuing buyback, he miraculously had an idea it may be related to a wiring harness issue. This was based off his experience with a Sierra pickup (5.3L, not our 6.2L) that had similar behavior. We left the vehicle and, wouldn't you know it, they replaced a wire and "have reasonable confidence" it resolved the issue. Two weeks later, it's back in the shop for key fob not detected (after already driving). Truck is in gear and you cannot move...another huge safety concern. It's a dud. We have also had to have all 8 injectors replaced due to rough idling and the steering gear replaced from faulty manufacturing that creates a clicking while turning the wheel, the car is at the dealer and we will not be taking it back. We are going through the offical buy-back process with GMC.

Vehicle has a vibration when going between 60-70 miles per hour on highway. The vibration starts and stops over and over again. Vibration last about two seconds each time. Took vehicle to dealer they said the issue was caused by recall that GMC was trying to fix. Currently no part is available to fix vehicle. Instructed to just keep driving vehicle with the vibration until a part is issued.

When driving at highway speeds in the rain, water pools on the drivers side and passenger side door window at the bottom front of the window blocking the driver's view of either side view mirror. I went to the dealer in carson city nv, and service director stated they had this problem with trucks since 2007 and there has been no solution.

- Gardnerville, NV, USA

My wife and I were driving on the parkway at about 65mph when we heard what sounded like a gunshot in the vehicle. We pulled over to the side of the road only to find out that the sunroof literally exploded on the car. All of the glass that was left was bowed upward which would indicate that the sunroof explode outward and nothing hit the roof of the car. When we brought the car to GMC they claimed that something must have hit the sunroof to make it explode which I know did not happen. Needless to say, GMC is unwilling to cover the damages to the car under the warranty.
