2023 Chevrolet Tahoe Engine

On December 30, 2025, I was driving the Tahoe at a highway speed in Oklahoma City, Oklahoma. I experienced two engine shut-offs. I was able to get the Tahoe to the Chevrolet dealer in Midwest City, OK. Advisor Tim took care of the vehicle and said that they "couldn't replicate the problem." He did mention he had to add engine oil because it was a quart low. We noted that we are currently conducting an oil consumption test with a Chevrolet dealer in Elk Grove, Illinois. He said we had a strong case for it, but the Tahoe was safe for traveling back home to Illinois. The following days, the Tahoe performed well without any issues. On January 3, 2026, we left Spencer, OK, and headed back home to Illinois. Without any warning, while driving at highway speed, the engine shut off completely and would not restart. The failure occurred at approximately 9:00 pm on a pitch-black expressway about 40 miles from Rolla, Missouri. I was traveling with my wife and two children. We were stranded on the highway shoulder. A state trooper was dispatched for safety. The Tahoe required a tow over an hour later, and we had to take a Lyft to a hotel. Logistics at that time in that location were complicated. Our family was terrified for our safety. Today is Sunday, and the nearest dealer is closed. We will have it dropped off tomorrow, January 5th, and go from there. We do not know how we are going to get back to Illinois. We have work and my son has school. The vehicle is currently disabled and under manufacturer warranty. This was a serious safety incident involving loss of engine power at high speed.

My 23 Chevy Tahoe was diagnosed with catastrophic engine failure on 04/02/2025, and per recall N252494000 a case for engine replacement. That replacement was completed and the case was closed on 06/02/2025. Since that time the new, replacement engine has been consuming oil at a high rate, is running with intermittent lag and I am waiting for a diagnostics appt with Chevy.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while her husband was driving at 70 MPH, the vehicle experienced a loss of automotive power. The check engine and "Oil Pressure Low" warning lights illuminated, and the vehicle unintendedly decelerated. The contact stated that while driving at various speeds, the message "Press START Button" was displayed, and restarting the vehicle temporarily fixed the issue. The contact stated that after further inspection, the contact became aware that the vehicle had independently shifted from neutral(N) to park(P). The vehicle was towed to a local dealer, where it was diagnosed; however, no cause for the failure was determined. The local dealer advised the contact that the oil level was possibly low, and an oil consumption test was needed. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign: 25V274000 (Engine and Engine Cooling); however, the VIN was no longer included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 33,253.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that after the vehicle was serviced at the local dealer, the message "Add Oil" was displayed, and the vehicle continued to experience excessive oil consumption. The cause of the failure was not yet determined. No further information was available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 18,000.

I purchased a 2023 Chevrolet Tahoe on December 17, 2025. On January 17, 2026, with approximately 17,000 miles, the vehicle experienced a catastrophic engine failure while I was driving. The engine seized without warning, causing a complete loss of power and leaving me stranded on the side of the road. At the time of the incident, my newborn child was in the vehicle, creating a serious safety risk. The vehicle had no prior warning lights or indicators before the failure. After the incident, I learned that there was a known recall or service update related to engine oil viscosity for this model year. This information was never disclosed to me at the time of purchase, and no recall documentation or corrective service was provided prior to delivery. I have since been informed that engine replacement will take over 30 days due to parts availability and that no loaner or rental vehicle is available during repairs. Given the catastrophic failure shortly after purchase, the undisclosed recall, extended repair time, and safety implications, I no longer feel the vehicle is safe or reliable.

The idler pulley was squealing. Dealership I took it to said this was the 3rd one they've had to replace in the last few days.

on [XXX] we bought our 2023 Tahoe High Country from Jeff Gordon Cheverolet in Wilmington NC. In April 2025 a recall was announced on our car for engine failure. In June of 2025 we received a letter stating that a fix for the recall was to have an inspection done. If passed, then an oil change and new cap would be done. This was completed. on [XXX], I was on the highway accelerating to get up the speed, when I heard a loud pop noise. Then i heard loud knocking coming from my engine, the check engine light came on with the traction light as well. The car then had sluggish acceleration and would not accelerate but would have high than normal RPMS and rev when trying to accelerate. I knew then that I had engine failure. I was able to get the car to a safe place and called the dealership right away. They got it towed to Marine Chevy since it was closer. The next day they did an inspection on the vehicle and said the camshaft and lifters were broken and had to be replaced. I said I would need a new engine replaced due to the damage and recall. I was told it would not be under recall because it was the top and not bottom. They said the GM refused the new engine but would not tell me if it was the General Manager or General Motors that refused. I called and texted multiple times asking for pictures. They refused to send me any until 9/9 after multiple attempts. They only sent me one of the rods and rocker arms showing a rod bent and stated it was the lifters. still no pictures of the camshaft broke or lifters. These problems already have multiple class action lawsuits out for this particular engine failure. I was told the recall would still be on the engine even after the repair, I can still have engine failure. I refuse to pay the money for this car to continue to be in the shop due to a bad engine that was put in these models. I also have a case open with General Motors for replacing the engine as well and they are refusing to help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When i asked Kunez Lake Geneva, Wi. When the engine recall would be taken care of. I was told that GMC has to order the recall first. Then when asking about the process of inspecting. They informed me they would listen to the motor and decide if it was effected or not. I paid $82k for this vehicle. I find that listening to the motor isnt a thorough way of inspection. After they deem the motor ok. There going to put higher viscosity oil & an oil cap. What if something happens in the future. Is my familys life safety not important? Summary General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2021 – 2024 model year Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with the 6.2L V8 gas engine (RPO L87). The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure. Safety Risk If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. Remedy Dealers will inspect and, as necessary, replace the engine. Vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filter replacement, and an owner’s manual insert.

We were driving on the highways, we had to break and the car shut off, we barely made it to the side of the road and the car would not turn over, start, or go in to neutral, which was very unsafe. Had to have it drug on the tow truck since it wouldn’t go to neutral and at the dealer it had 17 codes. The engine seized and they are having to order a new engine.

Sudden engine failure while driving at high speeds - was not aware of any recall.

Engine connecting rods and crankshaft have manufacture defects that could cause engine failure resulting in a crash. Driving in a large city with an infant and toddler makes the possibility of sudden engine failure extremely dangerous. It puts everyone in the vehicle at risk but especially the children at a huge safety risk. Engine makes odd sound but multiple Chevy dealerships say they won't look at it because they don't have an answer from GM.

I took my car into the Fowler Chevrolet (AKA Century Chevrolet) Dealership in Broomfield, Colorado to get the engine recall addressed for my 2023 Chevy Tahoe-RST. I was told GM doesn't have a solution and has not sent any parts to the dealerships to deal with the recall. This is a significant safety issue/concern since I drive my [XXX] daughter every day in this vehicle. How is an OEM like GM allowed to get away with not having an immediate fix available to such a significant safety issue where an engine just fails and could fail without any warning lights on a highway. Extremely dangerous and nerve racking to drive this vehicle knowing there is this safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

Feels like the transmission is slipping. When I step on the gas it makes a jerking/ tugging motion like its pulling backwards and feels as though it has no power. It’s gotten progressively worse now over 10k miles and I should not have any engine problems with a new car. This happens every time I drive it. The problem is not fixing itself it’s getting worse by the day.

Engine performance issues, engine hesitation, abnormal shifting, and reduced propulsion. Interior dash and radio illumination goes black. Blinkers fail to work; no sound comes from the radio and speakers. Mirrors fail to tuck after command given to do so.

I was driving on Highway and system said engine oil hot. 10 seconds later the engine stopped. Could not get it restarted as I moved over to the shoulder. Had vehicle towed and engine was seized. 28,000 miles on vehicle.

Engine: Power lost and engine shut down. Yes, it is available for inspection. Warning Lamps: Engine lamp came on: [XXX] [XXX] Engine shut down while driving. While bring my Grandson, home from school. I was on the ramp to exit the interstate, at the stop sign I lightly touched my brakes because I was going very slow, nothing was coming when I accelerated the engine totally shut down in between both lanes on a state highway. All of the warning lamps on the dashboard were lighting up and blinking, all of the alerts were making noises, no power and I had no control of the vehicle, then the “press start signal” came on, I had to quickly place from drive to park, and then press the start button to crank the vehicle. While this was going on my Grandson asked me in a startled voice “what’s happening”. Scary is not the word “I saw my life and his life flash before my eyes” with my Grandson in the vehicle. That’s a [XXX] of a feeling that you never want to experience. Then he said “this is nothing but a tin can ”. All of my family calls this vehicle a “Tin Can”! This was a very dangerous situation that could have been life-threatening or death. The problem has not been reproduced. Dealership sent a GM Field Service Engineer to inspect vehicle on 3/18/25. I have had many problems with this vehicle that cannot be diagnosed. Engineer test drove twice and scanned for codes before and after test drives. His findings: no codes found, was unable to reproduce power loss, and loose negative terminal on battery post tightened.
