2015 GMC Yukon Engine Problems

Noticed a tick sound. Sent to dealer. Lifter failed. Bent push rod. Took it in Nov 24th. Charged $7,100. Fixed all lifters and bent push rod. Was turning around in my driveway and vehicle just shut off. Took it back to same dealer in Jan 27th. Bad lifter. Same push rod. Still in shop. That’s two months and 2,000 miles and had same failure. That is absolutely ridiculous GM and I should be compensated for this. It has costed me $7100 dollars. They are fixing with a two year warranty but if the failures are so close together, who’s to say it won’t just keep happening. Not only is it a safety issue, it is hurting my finances. I drive this vehicle 2 miles to work at 25 mph, and religiously change the oil at 3,000 miles. It didn’t even get an oil change before it failed again. I am not happy and GM needs to be sued for this. I owe 20,000 on this truck and have spent 7,000 already, and it keeps failing. There needs to be a recall for this model year, and it needs to be a permanent fix. GM knows the quality of this motor is horrible and they won’t do anything about it. It’s not safe. They can my truck for $20,000

While driving my 2015 GMC Yukon Denali on the highway, the vehicle suddenly began shaking and lost power. I immediately exited the highway for safety and had to “nurse” the vehicle about two miles at 10–15 mph to reach home. The vehicle would no longer run afterward. A mechanic later diagnosed a lifter and camshaft failure. This is a known and common issue with GM 5.3L and 6.2L engines that poses a serious safety risk when it occurs at highway speeds. No warning lights or prior symptoms were present before the failure. I did not report it to the dealer, but the vehicle had to be towed to a mechanic for diagnosis. The vehicle is available for inspection.

The contact owns a 2015 GMC Yukon. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with compression in cylinder 7, resulting in damages to the engine. The contact was informed that the engine needed to be replaced. The vehicle was repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 100,000.

Started my 2015 Yukon XL, drove approximately 6 miles to get gas and was to head out onto the highway. After gassing up and starting engine it began to idle very rough with a shake going on and ticking noise. No previous signs of any issues. Slowly drove back to my house at 20 miles an hour and called Mandal GMC dealership. They suggested having it towed to them for inspection. Upon inspection they said the AFM/DOD #1 exhaust lifter was bad and needed replaced. They replaced all of Bank one lifters and said their was no damage to camshaft. Drove it that night after repairing it and everything seemed fine. They called the next morning and said when they started it up the ticking was back again. They then supposedly took off head cover and inspected the camshaft again and said it was damaged and I would need a new engine to the tune of $18,000.00. I purchase it in 2021 from them use and paid $33,000.00 and now still owe even more than the engine repair. I said it would cost more than the vehicle was worth and they had done $4,000.00 of repair that didn’t even get the issue fixed. I am a senior on Social Security and can not afford to continue to pay 20,000.00 for the loan and then another $18,000.00 for a faulty engine design that caused the problem in the first place. May have to join the thousands of others in the class action to get GM to not put out such untrustworthy engineering. Now $37,000.00 piece of Yard Sculpture !! The morning that it occurred was the first sign of flashing engine warning on dash.

With my child in the car, on a highway with no shoulder, I experienced lifter failure. It caused the vehicle shake and lose power with cars driving behind me at 55-60 MPH with nowhere to pull over. The engine just stopped as I was finally able to make it to a driveway safely. Problem was identified by dealership and my engine had to be rebuilt. I purchased the car second hand 3 months prior with no warning or symptoms. The car was inspected at the dealership by the extended warranty company rep. The extended warranty only cover a portion of the cost. The collapsed lifter cause damage to the camshaft and bent rods. The car only had 107,000 miles. If I were not able to pull off before the engine stopped, my daughter and I could’ve easily got rear ended on a Major state highway. The car was difficult to control due to the engine shaking the entire SUV.

The Yukon was driving normally and just lost power while driving 55mph on the highway. Then I got off the highway to pull over and check it out and the Yukon started shaking while running and in Park. The truck would not drive over 30mph without shaking and what sounds like misfiring.

2015 6.2l yukon lifter failure oil changed 2000 miles ago and lifter failed and possible cam damage due to AFM lifter failure vehicle has 115,000 Miles and Gm knows about these lifter failures that can blow engines and cause serious accidents due to rapid loss of power and controls that GM already knew paid alot of money as a certified pre- owned and failed to disclose lifter defects to their customers now at shop for complete inspection and now needs possible new engine when all service requirements were met now looking at thousands of dollars for repairs if known i would have not bought the vehicle. And deceiving GM customers , currently waiting for diagnostic in writing but the courts approved recall already from same issues on 2019 and newer but same lifters are in the same 2015 AFM system

I write to express my concern over an issue with my 2015 GMC Yukon that has also impacted other community members. In April, my Yukon, with just over 70k miles, broke down as I was turning from Rte 14 in Pembroke, MA onto Rte 53. At the time, I had my 3 & 5 year old children in the car with me. I could not get my vehicle to restart & had it towed to a local mechanic. After our local mechanic could not diagnose the problem, on 4/25/23, I had the vehicle towed to Marty’s GMC in Kingston, MA, where it was purchased. I had to call Marty’s regularly to check in on my vehicle before it was finally inspected. After 2 weeks, I was told that the valve spring needed to be replaced & the fluids flushed. I approved those repairs totaling $1600. After a couple of days, I received a phone call that there are issues with the lifters & brakes which would add another week of repairs & bring the costs up to $5,500. After another week, I received a call that there was more work to be done increasing the total cost of repairs by an additional $1,000. When I finally picked the car up, I was notified that the estimates I received were miscalculations & my repair costs totaled $7,512.23. Since this ordeal, I have talked to several GMC owners with cars of a similar age & low mileage. These owners have experienced the exact same issues. Throughout my conversations, I learned there is a service bulletin out on the issue with the lifters, but no recall. The lifter issue is a serious safety hazard. I have made multiple attempts to reach someone at GM’s corporate office to try & initiate a formal recall for the lifters. No one has been able to tell me how a recall gets issued. This whole ordeal has been a massive burden, both emotionally & financially for my family. It feels as though my young children & I were put in harm’s way for a known GMC issue that could have been avoided.

I just got my vehicle into the dealership because it's 115 degrees outside and the air conditioning stopped working. I am 8 hours away from home traveling with 6 children so I begged them to squeeze me in the same day for repair and they did. The dealership is saying it's a Crack in the air conditioning condenser and it's $1,600 to repair. This is unbelievable. 80,000 miles on it. This should be a safety concern. Sitting in stop and go traffic for hours in 115 degrees is unacceptable. GM needs to fix the problem and do their customers right.

Pulling out onto busy road the vehicle make a loud noise and then failed to accelerate and lost power. It was three seconds before the vehicle then slowly accelerated. This continued to happen while driving. The dealer then advised that GM was aware of this issue and has not issued a recall to date. This loss of power was dangerous.

6.2L engine, collapsed hydraulic lifter AFM failure, required $7400 in total repairs. All lifters, camshaft, high pressure fuel lines, high pressure fuel pump, intake manifold & miscellaneous parts and gaskets replaced by selling Dealer at 94000 miles. No help of any kind from GM or Dealer. This is a WELL KNOWN FAILURE FOR THESE ENGINES!

The contact owns a 2015 GMC Yukon. The contact stated that while driving approximately 25 mph, the check engine warning light illuminated, and the vehicle started to vibrate abnormally. The contact had taken the vehicle to the dealer who diagnosed that the catalytic converter needed to be replaced. The vehicle had not been repaired. The manufacturer was not made aware of the issue. The approximate failure mileage was 120,058.

WHEN SITTING AT A LIGHT, OR STOP SIGN VEHICLE ACTS AS IF IT WANTS TO CUT OFF, CHECK ENGINE LIGHT IS FLASHING, WHEN I'M DRIVING VEHICLE THE CHECK ENGINE LIGHT STAYS LIT. I DID A SCAN OF THE VEHICLE AND THE CODE I GOT WAS P0303 WHICH IS FOR A CYLINDER 3 MISFIRE. I HAVE CHANGED OUT THE SPARK PLUGS AND WIRES, ALSO THE IGNITION COIL. I CHANGED OUT THE FUEL INJECTOR FOR CYLINDER 3 AND ALSO THE FUEL PUMP ACTUATOR. ITS STILL SHAKING, DON'T KNOW WHAT THE PROBLEM IS BUT I HOPE YOU GUYS CAN COME UP WITH WHAT I NEED TO DO NEXT. I'VE HAD TO SPEND MONEY OUT OF POCKET FOR THIS BECAUSE ITS NOT UNDER WARRANTY.

I AM WRITING TO NOTIFY YOU ABOUT A PROBLEM WITH THE TRANSMISSION IN 2015 GMC YUKON XL. GM IS AWARE OF A PROBLEM. THEY ISSUED AN INTERNAL NOTICE TO DEALERS IN FEBRUARY 2016. HOWEVER, THEY HAVE NOT NOTIFIED TO OWNERS IN THE FORM OF A RECALL. ON SEVERAL OCCASIONS, MY VEHICLE JUMPED FORWARD, WHILE DRIVING IN THE CITY, WHEN IT WAS STOPPED, IN DRIVE, WITH BRAKE ENGAGED. I REPORTED TRANSMISSION PROBLEMS TO MY LOCAL DEALER BUT THEY REPEATEDLY IGNORED MY CONCERNS. THEY KEPT GIVING EXCUSES THAT DIDN'T MAKE SENSE. I FINALLY PRESSED ON, REFUSED TO TAKE MY VEHICLE BACK AND REPORTED THE PROBLEM TO SEVERAL EXECUTIVES. THE PROBLEM WAS FINALLY DIAGNOSED UNDER DIFFERENT CONDITIONS AS STATED IN THE FIRST INTERNAL DOCUMENT IN MARCH 2016. THERE WAS A PROBLEM WITH THE TRANSMISSION. THEY FINALLY REPLACED THE TRANSMISSION FOR "ONE THAT DIDN'T HAVE A PROBLEM". GM ADMITTED THERE ARE PROBLEMS WITH TRANSMISSIONS AND THE PROBLEM HAS BEEN CORRECTED IN NEWER VEHICLES. THEY HAVE YET TO ISSUE A NOTICE TO CURRENT OWNERS THAT THEIR VEHICLES ARE AT RISK. I OWNED A 2015 GMC YUKON XL BUT CHOSE TO SELL IT OVER SAFETY CONCERNS AND LACK OF APPROPRIATE RESPONSE FROM GM CORPORATE. WITH 2 YOUNG CHILDREN, I SPEND A LOT OF TIME AROUND SCHOOLS (LIKE MOST OWNERS OF LARGE GM VEHICLES). I COULD HAVE INJURED OR KILLED SOMEONE. I FEEL IT IS MY OBLIGATION TO BRING THIS SITUATION TO YOUR ATTENTION. IF YOU INTERVENE, YOU CAN HELP TO AVOID ANY INJURIES IN THE FUTURE. IT IS CLEAR THAT GM WILL NOT VOLUNTARILY PROTECT THE PUBLIC.

WHEN THE CAR IS AT IDLE IN DRIVE IT BECOMES VERY ROUGH (FLUCTUATES UP AND DOWN). THIS HAPPENS ON AND OFF AND I HAVE NO CHECK ENGINE LIGHT ON. SOMETIMES THE CAR EVEN FEELS LIKE IT IS GOING TO STALL OUT. I HAVE HAD IT INTO THE DEALER AND THEY ADMITTED THEY FEEL IT AS WELL. THEY TRIED ADJUSTING THE MOTOR MOUNTS AND THAT DID NOT DO IT. AFTER HAVING IN THE DEALER FOR SEVERAL DAYS THEY CALLED ME AND SAID THEY CAN'T FIND THE ISSUE. THEY TOLD ME THEY WENT INTO ANOTHER 2015 GMC YUKON SLE AND STARTED FEELING THE SAME ISSUE. IT WAS STATED TO ME I MIGHT HAVE TO WAIT FOR MORE COMPLAINTS ON THE VEHICLE TO GET TO THE ROOT OF THE ISSUE. IT CONTINUES TO IDLE ROUGHLY AND I WANT TO GET THIS RESOLVED.
