2022 Chevrolet Suburban Engine

ON MY THIRD ENGINE 12626 MILES ON IT . HAD OIL CHANGED . OPENED OIL FILTER CANISTER FOUND METAL SHAVINGS BLACK SLUGE NEW ENGINE SERIAL N1251074N44X0872 THIS THE # FOR ENGINE 3

Engine locked up going 75mph on highway. The vehicle's 6.2L V8 engine was recalled in 2025. Result of recall inspection was to change oil type to 0w-40. The vehicle is in the process of being inspected by dealer.

I want to complain that my 6.2L V8 engine was “inspected” and they deemed it OK, then proceeded to make a requirement of thicker oil for its life. I was also given a long term warranty on the engine, however it is non-transferable, therefore the re-sale value of the vehicle is damaged beyond normal conditions. The engine is suspect, why else would it need thicker oil? The engine is all over the news with the recall, therefore why would anyone want to purchase my used vehicle based on that press and no further warranty? GM needs to make this right! That 10-year or 150,000 miles means nothing to re-sale value if is not transferable.

Car initially started stuttering on the high, check engine and traction control lights came on. I immediately went to the nearest Chevy dealership a mile away. Initially I had 20 error codes. The problem was the Left side lifters 4 of 8 stop working. Dealership recommended Replace Left lifters, 2 push rods, valve cove, head gasket. $5000. After starting the work. The technician could not repair the lifters because my camshaft is pitted and the RODS were rotating. Their recommendation is to replaced the whole engine to fully fix the problem. $12000 with 3 yr warranty. My SUV just 100kmiles.

This is the second engine failure. First engine was completed being installed on 7/26/24 also reported catastrophic engine failure. Second engine was installed completion date on 4/04/25 it also had spun 2 rob bearings

The contact owned a 2022 Chevrolet Suburban. The contact stated that while the vehicle was parked with the engine running, the front of the vehicle began to shake violently, with a knocking sound coming from the engine compartment. The check engine, traction control, and collision warning lights were illuminated. The contact called an independent mechanic; however, the vehicle was not diagnosed or repaired. The contact later visited the dealer and was informed that the vehicle needed to be brought in for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 97,000.

I own a 2022 Chevrolet Suburban (VIN: [XXX] ) that is included in NHTSA Recall No. 25V274 / GM Recall No. N252494000 for engine defects in the 6.2L L87 V8 engine. My vehicle was inspected at an authorized GM dealer today, on 9/23/2025 (Don K in Whitefish Montana). Instead of replacing the engine, the dealer performed the recall “remedy” of switching to higher-viscosity oil, changing the oil cap and filter, and providing an owner’s manual insert. However, the dealer service manager specifically told me that my engine will eventually fail due to the known defect and advised me not to drive the vehicle on long trips. He also told me to be careful driving if I have children, and it is only a matter of time before the engine fails, which will look like sudden shuttering, loss of acceleration and it will no longer run. He told me wait time to get a new engine after it fails is currently 8 months. This is alarming because the recall notice states that engine failure can cause sudden loss of propulsion without warning, which could be catastrophic going across multiple lanes of highway (from my home street), and entering and exiting my street via the 4 lane highway "suicide lane". I am very worried about this in the coming winter season with snow and ice. The current “oil upgrade” remedy does not resolve the underlying manufacturing defect in the connecting rod and/or crankshaft. Even after the recall service, my vehicle remains unsafe to operate, and the dealer’s own warning confirms this. I request that NHTSA review GM’s recall remedy to ensure that it adequately addresses the safety defect. A true remedy should involve replacement of the defective engine components, not just an oil change, or an immediate buy back of my automobile by the company so I can purchase another safer vehicle. My family and I do not feel safe driving this vehicle, and the manufacturer’s current approach does not eliminate the risk of catastrophic engine failure.

The motor on this vehicle has been on recall since April of 2025. Several phone calls and a cancelled appointment by the dealership has netted a consistent "we have no information and aren't ready to fix the vehicle." Today, I was directed to the NHTSA to self-monitor when my vehicle would be ready for repair or inspection. Meanwhile, I drive a Suburban because I have five children that I am constantly transporting to school, sports events, scouts, etc. I have grave concerns over an engine failure while I am transporting my children and the risk of an accident.

The contact owns a 2020 Chevrolet Suburban. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact stated that on several occasions while checking the oil level, there was no oil on the "dip stick". The contact stated that the engine consumed 2-3 quarts of oil approximately 4,000 miles. Additionally, the contact stated that while driving on several occasions at various speeds, the low oil warning light illuminated. The vehicle was taken to a dealer where it was diagnosed that the piston and piston ring were damaged due to excessive wear and sticking. The vehicle was repaired but the failure persisted. The vehicle was taken to the same dealer where it diagnosed that the cylinder head had failed and needed to be replaced. The vehicle was repaired but the failure persisted. The vehicle was taken back to the same dealer where the failure was not replicated. The manufacturer was not notified of the failure. The failure mileage was approximately 3,000.

The contact owns a 2022 Chevrolet Suburban. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that there was a knocking sound coming from the engine while remotely starting the vehicle. The dealer was contacted and confirmed that there was no part for the repair. The manufacturer was made aware of the issue. The failure mileage was approximately 15,000. VIN tool confirms parts not available.

The coolant control valve malfunctioned on this vehichle several times during the course of ownership. It causes the vehichle to run in limp mode. This part was replaced in July 2023 at ~40,000 miles as a result. The part again began to fail in june/july 2025 with a dealer visit and diagnostic in July. This causes a check engine light, reduced milage, reduced acceleration, constant fan running and fails state inspection Google searches indicate this is a very common problem, yet no recall has occured to date. The first repair was in warrantee and now the vehicle is out of warantee. If the part was not covered under the vehicle warrantee, the part and repair would have been covered by the part warantee. Becsuse of the initial powertrain warrantee repair, the part warrantee does not apply. This is clearly a defective design and part that requires recall and replacement at GM cost

Engine failed while driving. Vehicle began making clicking noise less than one minute for engine shut off while driving. Check engine light came on after engine shut off. Car was stopped at a busy intersection and couldn’t move. Car is currently at Chevrolet dealership and is in need of a total engine replacement

We experienced catastrophic failure while driving the vehicle on the highway. It stopped working with no warning leaving our family stranded in the lane with heavy traffic all around us. The steering wheel would not move the car would not go in neutral and there was a burning smell coming from the hood. My kids were terrified. We had to wait for state police and a tow truck while praying that the cars behind us would stop in time. We are very lucky there was not an accident. The car is with the Chevy dealer now.

53,000 miles. While on highway, engine turned off completely. Coasted off the exit ramp into a parking lot. Engine started again with no issue. 2 days later: engine started knocking very loudly. Vehicle completely died while driving on street. No start, no crank, couldn't shift to neutral. Dash would turn on, but that was it.

Engine failure while driving.

6.2 engine with catastrophic engine failure. No warning prior to failure.

My two children and I were traveling to another state and had been driving about 2 hours when the engine in my 2022 Suburban suddenly quit working while I was in the middle of a highway. I had just accelerated and merged onto a multi-lane highway moving all the way to the far left lane when my engine completely went quiet and seemed to quit working. The car all of a sudden shifted into Neutral and started losing speed. I had to put my hazard lights on and cross back across the lanes to get back over to the emergency lane on the right all while losing speed. We were all pretty scared because the Suburban just seemed to quit working and wasn't responding. I'm thankful we were able to get safely to the emergency lane before the car completely stopped. Once I was in the emergency lane, I tried to see if the car would go back into Drive position but it would not. I turned the car off and waited about a minute and tried to power it back on but the only thing that worked was the electrical stuff in the car (the screen for my dashboard and car play/nav system) and the engine remained quiet. Once the tow truck arrived an hour later, the worker tried to jump the engine but it did not respond. It was obviously scary and has been a huge inconvenience but it also left us in a very unfortunate situation because we were in a different state and did not know the area or anyone nearby that could come and pick us up once the tow truck arrived. I was pretty much stranded with my 2 daughters and all of our luggage in a different state on the side of the road.

6.2 liter engine that seized without prior warning or indication. Has been blown up since 12/24/24. Vehicle is currently sitting at the Chevy dealer. Dealer has stated the engine failure was solely seized connecting rod bearings. GM has denied the claim stating the vehicles has 62,000 miles on it, putting it 2,000 miles out of warranty. Numerous calls and emails to GM directly. Dealer claims no one has reached out to them from GM since warranty declined. GM is stating the dealer hasn’t responded to them and that there isn’t anything they can do at this time. GM is also refusing to purchase the vehicle back.

As I was driving, in July of 2024. I noticed that that I had a traction control system warning on my dashboard. I didn’t think of it to been serious. Then all sudden the engine kind stalled. So the car wasn’t going passed 40 miles per hour. So I managed to take it to dealership. Once there the technician mentioned to me that I wasn’t alone with this type of engine failure. He added and showed me another suburban with the issue. He said that the engine needs to be completely replaced. Because there is metal in the the oil pan. He added the cost of the repair would be $8000 to $12000. So that’s when I decided to take the car to the automation Chevy dealership. They confirmed the issue and charged me $8200 to fix it. I really expected GM to cover the cost. But I was that they would not. Upon further research I found out that that many people had the same engine issue. I am hoping that the government should take action to investigate these engines failures. I think GM failed his customers especially in the COVID era of 21 and 22. Thx

While driving my vehicle, it suddenly shook, a vibration started, and then the car began misfiring. It wouldn’t accelerate, kept shaking, and several warning lights appeared on the dashboard, such as Engine, Traction, and ESC. At that time, I was with my two sons, aged [XXX] and [XXX] . We were turning onto an empty and quiet street, so our safety was not at risk. However, if this had happened in heavy traffic, it could have posed a significant danger, as the vehicle’s power dropped dramatically, and it all happened very suddenly. I took the car to a mechanic. Initially, the fuel injector was replaced, but the problem persisted, and the mechanic recommended an engine replacement. After that, I went to an authorized service center, and they also recommended an engine replacement. I purchased a new engine from Chevrolet and had the mechanic install it. The mechanic told me that this is a common issue and mentioned that two other Suburban engines were replaced this year. My next complaint will also be related to my second vehicle, which is the same model Suburban, experiencing similar issues. I own two 2022 Suburbans, and both have had their engines replaced in the past two months. The removed engines were sent to Chevrolet, but I have not received any information regarding their condition or the cause of the failure.

While driving my vehicle, it suddenly shook, a vibration started, and then the car began misfiring. I own two Chevrolet Suburbans, and since the same issue had happened before with the other one, I was more experienced this time. However, this time, there were also unusual noises coming from the vehicle. It wouldn’t accelerate, kept shaking, and multiple warning lights appeared on the dashboard, such as Engine, Traction, and ESC. The issue occurred as I tried to move forward after waiting at a red light. Since I had experienced this problem before, I immediately pulled over to a safe spot, ensuring our safety. I took the car to a different nearby mechanic. The mechanic stated that this is a common problem with these vehicles and that they encounter it quite often. I explained the previous incident I had experienced. The mechanic confirmed that the engine needed to be replaced. I purchased a new engine from Chevrolet and had it installed by the mechanic. I have already submitted a complaint to you regarding my other vehicle, which is the same model and year. I own two 2022 Suburbans, and both had their engines replaced within the past two months. The removed engines were sent to Chevrolet, but I have not received any information regarding the condition or cause of failure.

The contact owns a 2022 Chevrolet Suburban. The contact stated while driving at approximately 70 MPH, the vehicle began to shake, fumes came out from the exhaust, and the check engine warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed with an engine lifter failure. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 175,000.

Check engine warning light appeared on dashboard. When servicing the vehicle at dealership, they found catalytic converter not burning up exhaust gases properly. Need to replace y-pipe, part #86781749. I found NHTSA document N232419720 - Emission Recall Incorrect Catalytic Converter Service Part, that references my car make and model. I am requesting an investigation to have this included in a recall and to have replacement costs reimbursed.
