2022 GMC Sierra 1500: engine knocking or ticking

Filed Nov 4, 2026 · Engine · LA

I am filing a safety complaint regarding my 2022 GMC Sierra 1500 Limited Denali equipped with the 6.2L L87 V8 engine. My vehicle has developed a persistent engine knocking noise that becomes more noticeable as the engine reaches operating temperature. The knocking continues despite completion of the applicable engine recall work. I am concerned that this condition may be related to the premature internal engine failures associated with the GM 6.2L L87 engine. The continued knocking raises concerns about a possible connecting rod bearing or other internal engine component failure. A sudden engine failure while driving could cause an unexpected loss of propulsion, creating a serious safety hazard, particularly on highways or in heavy traffic. I am requesting that the federal safety agency investigate whether the completed recall remedy adequately addresses vehicles that continue experiencing abnormal engine knocking and potential internal engine damage. The engine remains installed in the vehicle and is available for inspection. I am requesting further investigation into this safety concern.

At three years old with 37,000 miles on it, the engine started ticking loudly consuming oil when I went to look it up. I saw there was a recall. Nobody had notified me about the recall. The technician said it failed their diagnostic test and I would be getting a new engine. Nine weeks later, I get a new engine. One year later at 51,000 miles the transmission failed.

engine was replaced by Classic GMC in Katy/Houston, TX in dec 2025 under L87 recall. My wife was driving and was stopped on an off-ramp but still in the traffic lane. It started with a light knock that i thought i heard the day before, but then died on freeway within maybe 15 miles of her driving. Unknown if it knocked louder, but wife says she never heard anything until it died and check engine light came on and engine would not restart. Required tow to GMC dealer. They diagnosed and took 2-3 weeks to source and replace the engine. In july 2026, started hearing very similar noise - this time apparently the water pump seized. Heard noise and got home within about 10 miles. Checked under hood and drive belt was significantly frayed and knocking/metallic noise was intense. Towed to Classic GMC. Not covered under any warranty - my replacement engine did not include a new pump. Cost $1700 at Classic GMC - they said it had no relation to the engine replacement or labor done in December. Unrelated, but icing on the cake - less than 2 hours and 10 miles of picking it up from service, lots of warnings about lane keep, adaptive cruise control, and park sense started going off. Returned to same shop the next day and *poof* the camera and processor that runs all those systems was somehow fried. Unrelated of course. $1200 a but they claimed GM graciously offered to “split the cost with me 50/50” since I just paid so much for the water pump. Picked up from service and traded vehicle in with 2 days.

I own a 2022 GMC Sierra 1500 AT4. The vehicle developed a clear engine knocking noise. I first brought the vehicle to the dealership while under 150,000 miles for inspection related to a recall. The dealership only performed a computer scan and oil change and stated no issue was found. No mechanical inspection was performed despite the noise. The issue continued and worsened. I returned to the dealership and the vehicle was kept for three days. During that time, the dealership again denied the existence of the noise and stated the vehicle was operating normally. When I picked up the vehicle, I immediately noticed the same noise and requested the technician to inspect it again. At that time, the technician acknowledged the noise and confirmed it was related to the recall. Despite this acknowledgment, General Motors declined to repair the engine and closed the case, offering only partial assistance toward purchasing a new vehicle instead of fixing the defect. The failure to properly diagnose the issue during the initial visit and the subsequent denial during the second inspection allowed a safety-related mechanical defect to worsen. This condition may result in engine failure or sudden loss of power while driving, creating a serious safety risk. The engine noise indicates a potential internal failure which could lead to sudden loss of power while driving, creating a safety risk. The initial failure to properly diagnose the issue may have allowed a safety-related defect to worsen beyond repair.

This is separate for VIN [XXX] I had to change dealerships because Beck & Masten South / GMC would NOT provide me with a loaner after being told I was on the list and I was next in line. I waited a month and drove to them and spoke with the girl who oversaw loaners. I explained I had severe safety issues such as front-end wobble which is related to transmission issues. And the oil consumption issue and oil light. Once again, I was re-assured the loaner program was indeed still active and I would be put on priority. Again to no avail I had wasted too much time with Beck & Masten. After months of this I found out I did not have to take it to the dealer I bought it from. So, I took it to Monument Chevrolet. I explained my concerns related to the front-end wobble which was very intermittent. And the oil consumption issue which I was very concerned with due to the year model and mileage of the truck. Also, the 75,000.00 price tag was really has me extremely upset... Monument Chevrolet treated me well. I had actually brought it in and called about the steering which was greatly affected by the severe front end wobble more than one time. I was told at first the oil consumption was pretty normal. Until I told them how much I had to add between changes. I have attached two work orders to this complaint. These work orders show what was done at 18017 miles and 18323 miles. The later work order was when the PICO test was done. Also, an oil consumption test was started once I picked the truck up. After I had driven it for 2077 miles and was bringing the vehicle back to Monument Chevrolet, as instructed for the oil consumption results, when a loud squeeling, then hard knock, power loss and I pulled over. I called Monument and was instructed if I could get it to start and bring it. I drove it to them while knocking and rough running. It has been in the shop for over 2 months for an engine replacement. 2077 miles after recall work! REFER TO: COMPLAINT XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOI

While driving at 72moh, the engine started to knock/tick and then shifted into neutral indicating to press the start button again. Once I coasted to a stop, the truck shifted into park by itself and indicated to hit the start button again at which point it was completely locked up and inoperable. The vehicle had an engine replaced at 13,000 miles and currently has 54,000 miles on it. It now needs another complete engine replacement. The vehicle also had the recall inspection done in DEC/2025 and found no issues.

The vehicle is subject to Safety Recall N252494001 (the federal safety agency Campaign 25V‑274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • Safety Risk: The defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • Dealer/Manufacturer Confirmation: The problem was confirmed via the issuance of Safety Recall N252494001. A dealership inspection was performed previously as part of the recall. • Warning Signs/Symptoms: Common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The Issue with the Remedy: Federal law (49 U.S.C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, GM has mandated a switch from 0W-20 to 0W-40 (dexosR) oil for the life of the engine to prevent bearing failure. However, the dealership and manufacturer are refusing to provide this mandated safety spec change without an ongoing $85 surcharge per oil change. While they performed the initial "inspection" oil change for free, they are now using the recall-mandated spec change to create a financial burden on the consumer. Because 0W-40 is now the mandatory factory requirement to prevent the safety defect, charging a premium for it constitutes a failure to provide the recall remedy "without charge." General Motors refuses to offset this cost, effectively penalizing the owner for a manufacturer safety defect. The dealership is also failing to honor my Platinum Wrap warranty and GM Prepaid service contract to perform the continued oil changes without additional charges.
