One week after purchasing the vehicle I broke down due to an oil pressure sensor. Two weeks after that I broke down (stalled out in the road) due to 2 lifters collapsing and the camshaft being damaged. After replacing all lifters, the camshaft, spark plugs and wires, as well as another oil pressure sensor just in case the other one was bad I still have low oil pressure. This cost $3,000.00! I left the shop and broke down on my way home with a flashing engine light and the stabilitrak light and message flashing. It shook so hard I thought it would explode in the road and then stalled out! It was towed back to the shop where it continues to sit. Its been there 3 weeks. Its been at the shop longer than I've gotten to drive it. After googling what might be causing the problem it appears this is not uncommon and gmc/chevrolet is well aware of the faulty engine. Thousands of posts are on different sites complaining how even though they have put their vehicle in the shop and had the repairs done, there is something in the engine that causing the issues again! The manufacturer is well aware they are putting lives at risk repeatedly and causing financial hardships for the consumer but it is obvious they are concerned only about their bottom line and not lives.

At 75,000 miles I wouldn't expect to have this many issues out of such a nice expensive truck... The check engine lights comes on and off and it pleases. When the check engine light is on the remote start doesn't work. The tail lights work when they want to and to fix a tail light just 1 is $800.00. While driving all types of warnings and lights start coming on in a rapid warning annoyance. I've never hooked a trailer to this truck and it keeps giving me some type of trailer braking system warning. The cruise control works when it wants to. Big issue!!!!! The transmission is slipping!!!!!!!!!!!! When driving it will give a hard jerk as if it's having trouble shifting. Doing this at any speeds, anytime during accelerating. So many issues out of this truck it's to the point we are throwing away a ton of money onthis thing!!!!!

Just got this vehicle 2 months ago. Brake lights seem to work when the want to. Have read others reviews and seems everyone with this vehicle is having the same issue! The cruise control works when it wants too,. Check engine light is off and on had it checked once while on and was told it's an o2 sensor. When the check engine light is on remote start won't work. Seems the brake light issue is purposeful since so many people have the same issue and it costs so dang much to fix it! For such a nice vehicle and expensive payment you would think there would be no issues.

I put in another complaint and forgot to add maybe the most important details!!!! I have noticed my cruise control, check engine light, brake lights, and remote start though I'm having issues with them all working only when they want to it seems when it's hot outside all of these things go hay wire and when it's freezing cold (colorado winter) everything works fine. Today high of 40 everything is working fine... Highs in the 80+ everything seems to not work. So it's basically boiling down to electrical issues when it's hot and no issues when it's freezing cold. Can someone please fix this!!!! I've seen numerous complaints of others having the same issues with heat and electrical issues.(cargurus.com) please someone do something gm needs to fix this!!!!!!!! I only hope others have made these complaints so gm can be held responsible! 800$ for a brake light get out of here!!!!!!!! And that's just the price to fix the brake light when it decides not to work and I'm not paying that much to fix one issue when it seems to be something with this vehicle and heat!

Over the past four months my 2012 yukon has been hesitating / stopping. I have accelerate into in the intersection and vehicle hesitated almost causing an accident. The check engine light has came on and off numerous times, flashing stabilization and traction switching on and off. I have taken it to the dealership at least five times each time they said there was nothing wrong with my vehicle second to the last time they stated I needed a new fuel pump which they replaced and the problem continued with in two days and continues to this day . The last time I took it in they stated there is an issue with gm vehicles from 2013 to 2017 causing stalling hesitation lack of performance in a setting in high ambient temperatures and there is no fix for it . I believe this is a great safety risk for individuals who live in high climate areas .

While driving on the highway with my cruise control set between 50-70mph, I began noticing my speedometer beginning to jump between 0-120mph causing the limiter to kick in and me losing the ability to control speed. Keep in mind I'm only going between 50-70mph. This later began occurring without the cruise control on. Shortly after this began happening another problem started. Now when the cruise control was set between 50-70mph, the engine would automatically accelerate maxing out the RPM's and sending the vehicle to approximately 80-90mph before I had to hit the brakes or completely cut off the cruise control. Later on when I would set the cruise control the vehicle would begin to jerk violently, revving high then going back to normal before revving high again and me shutting off the cruise control. There was never a check engine light the whole time this was happening. I immediately took it in to the dealer I purchased it from, randy marion gmc in huntersville, nc, to be checked. I was told that I had a bad mass air flow sensor. That was replaced but the problem was still occurring. I took it back a second time and they could not find anything wrong so I began reading blogs to see if anyone else has had this same problem. Some had similar issues and said the ignition coils may be bad. I had those checked and all were good. This vehicle has never been in an accident and I am the only owner. I've contacted gm, general motors, about this and was told that there were no recall issues but have yet to have my calls returned by the person handling this case. This vehicle is not safe and no one seems to be listening.
