2016 GMC Yukon Engine Problems

Ticking sound coming from engine, possible damaged camshaft lobe due to lifter roller failure. It can cause sudden engine failure, significant power loss, and unexpected stalling while driving, increasing crash risks. The issue is linked to AFM (Active Fuel Management) system failures. The problem has been diagnosed by dealer service department. No warning lamp or message, problem first appeared 7 April 2026.

Misfire then replaced plugs,coils and wires, then change fuel injector, and problem still there, then started truck and was tossing power and motor started ticking. Every shop told me this is the same common problem they're having with all 6.2L engine and they're all on recall by GM. I know 2016 are not in recall but I think they should be because this problem is in all 6.2L engine

On [XXX], while idling in my driveway the engine abruptly stopped with a loud clunk and refused to turn over when I attempted to restart it. The vehicle was towed to Bergstrom GMC in Appleton WI. Upon inspection it was determined that a connecting rod and crankshaft bearing had failed requiring replacement of the engine. The vehicle has a 6.2-litre V-8 engine with 106,000 miles on it. The vehicle is currently still at the dealership waiting for the engine replacement at an estimated cost of $18,000. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Check engine light came on. Immediately went to reputable local repair shop. Shop advised push rod bent due to faulty engine. Advised to call GMC because not normal wear and tear. Called GMC expressed my frustration about this being preexisting issue w this engine. GMC corp told me I had to ship to GMC dealership at my own expense then they could help me. Local GMCs backed up 6-8 wks. Towed car 1.5 hrs away. Mechanic told me not to worry this happens all of the time, GMC will take care of it. Pointed out a row of new trucks with my incl new Escalade with same issue. I spoke to a sales rep about trading my car in for new but he said engine issue still not resolved. He advised me to lease Escalade for $900 because by the time my engine blew my lease would be up; if not GMC fix under warranty!! Mechanic said new engine but GMC will take care of it. I waited 3+ months for GMC to authorize repair. GMC said they did not get docs but mechanic sent me verification of conversation and repair order sent to GMC. Mechanic received an unrelated warranty from GMC that said my issue was not covered. Mechanic said docs sent made no sense bc he sent the right warranty and he was sorry and embarrassed by GMC behavior. I finally paid over 14K for new engine. Picked up my car and drive a block and car still knocking and engine light came back on. I had returned my rental and no way home. In tears dealership gave me my rental keys back still all at my expense. The mechanic calls me two days later to tell me my torque needs to be replaced. I am hysterical, 14k spent, and car still not fixed. GMC told me to pay additional funds for torque converter or pick up. Threatened to charge storage fees. When I discussed their liability GMC became very rude and antagonistic. They cut off my communication with their lead mechanic. Took care of back to local repair shop. He said this smells of a law suit so would not touch vehicle. I all communication 106 more files to share.

At 90k the engine stopped working, no warning or lights went off. 6.2L Lifters and bearings., The dealer gave us 14k for the car and we then went and bought and escalde with the 6.2L, that has also seized at 14k miles within 13 months of purchasing. The yukon has no reports of that on the car fax after our trade, which i found curious.

The engine failed and dropped down to limp mode while driving down the Hwy. Had to replace the engine for a toll of approx. $10,000. Truck only had 89,000 miles on it.

My 2016 GMC Yukon Denali was taken in for a tune up. When I received the vehicle back, I was told that there was possibly a microscopic pin hole in my engine because fluid (engine coolant) was under one of the injectors. I was told that I may need to trade in or get another engine. I refused both. The mileage at the time was probably 120,000. I purchased this vehicle brand new and do not see how an engine is needed so quickly. I was barely finished paying for it. I was told by a co-worker that she had to trade hers in because it was doing the same thing. She had also investigated and had learned that many of these vehicles have the same issues around 114,000 miles and beyond. I think these issues need to be addressed.

Radiator is leaking antifreeze because of excessive thermocycles within the cooling system caused by excessive cycling of the thermostat. Vehicle leaking antifreeze causing environmental hazards and possible overheating causing vehicle to shut off. GM knows about this and posted a service bulletin but will not repair when out of warranty.

The Active Fuel Management System caused excessive wear and tear on the engine, causing the lifters, push rods and valves to be damaged, while under normal operation and regular maintenance intervals. The damage caused, by this failure resulted in the yukon breaking down in the middle of the highway. Every shop/dealership we called all said the samething, this has been a common problem with vehicles equipped with this type of system and the only fix is to replace the motor. Luckily traffic was light that day or things could have been worse. Its dangerous enough to get stranded in the middle of the highway with no way to move the vehicle.
