2022 GMC YUKON Complaints

During normal driving conditions the vehicle had set code P18A1 in the ECM. Code set due to an internal short in one of the solenoids in the valve body assembly. This caused the vehicle to display "Limp Mode" and lose reverse gear and propulsion over 45 mph. The vehicle was parked and towed to the dealership for evaluation. Upon inspection by a certified dealer technician, it was found that a solenoid had failed and required replacing. As part of the entire valve body, the solenoid is not a serviceable part. The dealership had to replaced the entire valve body assembly per repair guidelines. Per the GM and NHTSA websites, my 2022 GMC Yukon XLT with a 10-speed transmission is not included in the recalls listed below even though the symptoms are identical. General Motors publicly acknowledged the 10-speed transmission valve body and solenoid defects, including internal electrical and hydraulic failures, through Safety Recalls, Special Coverage programs, and Technical Service Bulletins applicable to 2020– 2022 full-size trucks and SUVs, including the GMC Yukon. My vehicle’s model year, transmission type, failure code (P18A1), and repair align with those documented GM conditions and should be included in this recall.

Experiencing a stuck lifter in the DFM module. After doing some research, it appears there are a bunch of other people that are dealing with the same issue. The only recall was for the 6.2L engine but not the 5.3L. It appears that both engines are experiencing the exact same issue and GM hasn’t done anything to help with it.

Vehicle has 58,800 miles on it driving down highway started smoking and motor making a clanking noise.

Engine seized up while driving 60 mph on a known GM recall, after passing recall pico test

My 2022 GMC Yukon XL with the 6.2L L87 engine was previously subject to NHTSA Recall 25V-274 / GM Recall N252494000 for L87 engine loss of propulsion. The recall was closed by the dealer as “PicoScope Inspection — Engine Passed / Update Engine Oil Type,” with the oil/cap/filter remedy. The vehicle was later brought back to the dealer for engine noise/knocking, check-engine light, and engine oil light/oil warning concerns. The dealer has now confirmed that the dipstick was not picking up oil, the oil level was severely low, the oil condition was severely degraded, and abnormal engine noise was heard. My VIN also shows active GM Special Coverage N252494003 through 1/15/2032 or 150,027 miles. The dealer previously stated that the underlying PicoScope pass data from the recall inspection is no longer available to the dealership after submission. This is not the first oil-related concern. During a prior service visit in September 2025, around the same time the L87 recall was completed, the dealer documented an engine oil low message and an upper oil pan leak causing the low-oil message. I am concerned the L87 engine may be failing after the recall remedy was previously marked complete, creating a risk of engine failure or loss of propulsion while driving. I am also concerned the current engine/oil/noise condition is being treated as customer-pay/out-of-warranty before the root cause is fully diagnosed or reviewed by GM under Special Coverage N252494003.

Engine failure occurred while driving with two children in the vehicle, creating a serious safety hazard. The vehicle experienced a sudden loss of power and stalled completely while in motion, with no prior warning lights, alerts, or messages. Prior to this failure, the vehicle had already failed the GM PICO test related to the known L87 engine issue, and the recommended corrective action was changing the oil to 0W-40 synthetic and replacing the oil cap. Despite that intervention, the engine still failed at approximately 49,000 miles. A sudden complete engine stall without warning while driving created a dangerous situation, particularly with children in the vehicle. This raises concern that the prior corrective action did not resolve the underlying defect..

6.2 liter engine seized on the interstate, I lost propulsion as the car switched to neural on it's own. Auto was towed to Applegate Chevrolet in Flint, MI

Recently my vehicle was serviced under recall N252494000 at an authorized GM dealership. Following completion of the recall remedy, which included an inspection and oil change to OW-40. As a result of this recall remedy, I have experienced the following adverse effects: •Significant increase in oil change costs from approximately $80.50 to $171.21 •Noticeable decrease in fuel economy (previously 18-20 mpg, now approximately 15-16 mpg). •Ongoing concern regarding engine reliability and safety •Diminished resale value due to the known engine defect and recall history. It is my understanding that this recall addresses a known defect involving internal engine components that may lead to catastrophic engine failure and sudden loss of propulsion. I am also aware that the NHTSA has initiated further investigation into failures occurring even after the recall remedy has been performed.

On April 12, 2026, while traveling approximately 65 mph westbound on XXX in [XXX] (just east of Exit XXX), the engine in our 2022 GMC Yukon Denali failed without any prior warning. This occurred on a four-lane highway where I was in the lane furthest from the shoulder. The engine shut off, the vehicle automatically shifted into neutral, and I had to cross multiple lanes of traffic to reach the shoulder without power steering while the vehicle was rapidly decelerating. I had my [XXX] son and [XXX] dog in the vehicle at the time, which created a significant safety risk. VDOT arrived on scene within minutes but was unable to jump-start the vehicle. I contacted Southern Buick GMC Kia in Greenbrier, VA and arranged for towing through their service. The vehicle was towed to their facility the same day. On April 14, 2026, the dealership informed me that the engine had failed and contacted GMC headquarters to order a replacement engine under the vehicle’s VIN. The vehicle remains at Southern Buick GMC Kia in Greenbrier, VA, where it is available for inspection by NHTSA. Previously, a PicoScope test was performed on October 7, 2025, under warranty code XXX. At that time, the engine was determined not to be eligible for warranty replacement; the oil was changed and a new oil cap was installed.

Engine failure with the 6.2 engine. My engine failed the Pico test in July of 2025 with 66k miles. The entire engine was replaced and I was told this would “fix” the engine issue. On April 25, 2026, my engine failed while I was driving at highway speeds. The engine was knocking and I pulled over as I could not accelerate it. I had it towed and was told by the dealership that the rod bearings failed and I would need an entire new engine. 9 months and 10k miles after a brand new engine was installed. This will be the third engine in this vehicle since I’ve owned it. GM’s “fix” for the 6.2 recall is not a fix. It’s pushing the problem down the road, risking lives by putting people in vehicles with known engine failures and no true fix.
