general problems of the 2023 Chevrolet Tahoe - part 1

On 4/23/25, the check engine light came on and the vehicle reduced power. It was taken to dealership and a warranty service was performed, l87 engine loss of propulsion. The vehicle was in service for 90 days. On 7/15/26, vehicle shifted itself into neutral while driving on the highway, with 4 kids in the car. This is a safety issue for our family and all around us, as car loses ability to drive at interstate speeds. It would not go back into drive, needed to pull over and get towed to dealership. Dealership diagnosed it needed a new engine and radiator; it was in service for 60 days. On 10/10/26, vehicle shifted itself into neutral while driving with one kid in car while driving on the highway. Vehicle gave the "conditions not correct for shift" and would not go back into drive. Vehicle was shut off and was stalled on the highway, after a time of it being off, vehicle started back up and the check engine light was on. This is a safety issue for our family and all around us, as car loses ability to drive, once again, at interstate speeds.

While traveling on I-684 at highway speed, my 2023 Chevrolet Tahoe with 43,000 miles suddenly shut off without warning and automatically shifted into neutral. I had a complete loss of propulsion. As a car guy who has been following the gm 6. 2l engine recall issue, I suspected it could be that. I was traveling in the left lane and had to carefully coast across active lanes of traffic to reach the shoulder. My wife and two young children were in the vehicle, and the sudden loss of propulsion created a significant risk of collision. There were no warning illuminations, messages, or other symptoms that I observed prior to the failure. The vehicle was subsequently towed to my Chevrolet dealer for diagnosis and is available for inspection upon request. As confirmed by the dealer, the engine completely seized causing the loss of propulsion. I will also share, about 1 year ago after the gm recall was issued, I took my truck back to the dealer. They cleared the engine for the propulsion issue, changed the oil for 0w40 and changed the oil fill cap in line with gm recall standards.

The afm/dod system failed and resulted in lifters and rocker arm failure.

I was picking my Tahoe up after a replacement on the blown motor was complete. (l87) I started it and immediately knew something was wrong. I reported it to the service advisor and the response was there were no warning lights so it must be fine. I asked them to sit in my car and they agreed it was not running right. They took it back and replaced a sparkplug that was causing the #2 cylinder to misfire. Almost 3 months later I was driving on the freeway when my Tahoe felt like it was going to stall. Again I had no warning lights appear. The diagnostics showed the same #2 cylinder misfiring caused by another sparkplug issue. This is all within 2,500 miles on a brand new engine.

* lifter bores and camshaft. Yes * the vehicle started to shake and started sending out alerts for multiple problems while we were driving on the interstate * yes. Bale Chevrolet estimated approx. $10,000 repair bill * no. It's currently at the dealership * as the car began to shake we started receiving numerous warnings, but not prior to the shaking.

Our Tahoe was included in the recall. The dealership inspected it, found no issue at the time, and told us to switch to a different oil viscosity, which we did. This vehicle has only ever been serviced at a Chevrolet dealership. On August 20th, while driving on the highway, the engine shut off without warning and we had to coast to the shoulder. We attempted to restart it several times, but the engine would not hold an idle. After shutting off all accessories, including the a/c and radio, the vehicle finally started. We brought it back to the dealership for inspection, and once again they could not find any issue. Today, September 14, 2026, we heard loud clanking coming from the engine. We pulled over immediately and had the truck towed to the dealership. At this point, we believe the engine is no longer serviceable and will need to be replaced. We do not believe the change in oil viscosity is an adequate fix for the 2022 to 2024 6. 2l engines covered under the gm recall, including the one in our Tahoe. An engine dying without warning at highway speed is a serious safety hazard, and we were fortunate it didn't end in a collision.

1 week and 1 day later we are stranded again on the side of highway going full speed in our Tahoe. We took it to two different certified chevy dealerships and they gave us a vague resolution and this issusr is not fixed at all. Our engine is locking up on us at full speed on the highway. This vehicle has 83,000 miles on it and we’ve maintained this vehicle very well.

The contact owns a 2023 Chevrolet Tahoe. The contact stated there was a misfire in the engine, with the engine warning light illuminated. The message “collision mitigation system off” was displayed. There was a burning odor coming from the vehicle after the failure. The vehicle started shaking abnormally. The vehicle was taken to the local dealer, where it was diagnosed and determined that the lifter and crankshaft needed to be replaced. The contact purchased a rebuilt engine, and the engine was replaced at another service center. The failure mileage was approximately 82,000.

We were driving full speed down the highway and the vehicle completely shut down steering wheel locked and we were stranded for six hours. Turns out the dealer said it was just the battery and they fixed the grounding of the battery. I’m sorry but I’m not satisfied with this response. I’m scared to drive this vehicle.

I am submitting this complaint regarding my 2023 Chevrolet Tahoe equipped with the gm 6. 2-liter v8 engine. VIN: [xxx]. At approximately 40,000 miles, the original engine experienced a major failure and was completely replaced by a Chevrolet dealership under warranty. I have now driven fewer than 10,000 miles on the replacement engine and am experiencing a very similar engine-related problem again. The vehicle is currently back at the Chevrolet dealership being inspected and repaired. This is extremely concerning because the original engine failed at only approximately 40,000 miles, and the replacement engine has developed a similar problem after fewer than 10,000 miles. The gm 6. 2-liter v8 has been the subject of numerous reported engine problems and complaints, and I believe this repeated failure warrants NHTSA’s attention. I am concerned there may be an underlying or recurring defect affecting these engines that has not been adequately addressed. I am also concerned about the potential safety implications of an engine or valvetrain failure while driving. An unexpected loss of power or significant mechanical failure could create a dangerous situation, particularly at highway speeds or in traffic. I can provide dealership documentation showing the original engine replacement, the mileage at which it occurred, and the current repair visit. This documentation establishes that the vehicle has experienced significant engine-related problems twice within a relatively short period, including a similar problem with the replacement engine after fewer than 10,000 miles. I respectfully request that NHTSA document this complaint and review whether there is a broader pattern of premature or repeated failures involving the gm 6. 2-liter v8 used in 2023 Chevrolet Tahoe vehicles and whether further investigation or corrective action is warranted. Replacing the original engine did not resolve the issue, as the replacement engine has now developed a similar problem. Information redacted pursuant to the freedom of information act.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was taken to a dealer, where the NHTSA campaign number: 25v274000 (engine and engine cooling) remedy was completed with an oil change and oil cap replacement. Approximately three months later, while the contact's wife was driving approximately 45 mph, the engine stalled. The driver was able to coast to the side of the road. The vehicle was towed to the dealer, where it was diagnosed that the engine had failed. The engine was replaced. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 22,000.

A couple weeks ago, the truck suddenly started running rough and the front collision avoidance system failure message displayed. Immediately took it to the dealership. Computer read out showed #7 fuel injector failed. Repaired and was fine. Yesterday, 8/27/26, same thing happened again. Immediately went to the dealership. Now #4 fuel injector failed. Service manager just called and states that Chevrolet does not have that injector and on backorder with no date of expected delivery. No other chevy dealer has #4 fuel injectors either. Tells me that there is an overwhelming demand for fuel injectors that indicates a defect. Meanwhile, the truck is out of service and gm is not addressing the issue to replace all the defective injectors.

We were driving on the highway and the engine started making a ticking noise and afm light came on. Took the car to the dealership for inspection and they said the lifter had collapsed and it would cost $1000 to tear the engine down to see if the camshaft was damaged. Asked for the estimate to replace camshaft and lifters and they quoted $10,000.

My vehicle, 2023 Tahoe, previously had the gm recall 25v-274 / n252494001 remedy performed (0w-40 oil swap) in October of 2025. Despite completing the manufacturer's official recall remedy, the engine suffered a sudden, dangerous loss of motive power at highway speeds when I was making an out of state move and traveling alone; it was terrifying. I had to have it towed to the nearest dealership and that is where it is now as I had to leave since I was in the middle of moving. I need a new engine. I have no idea how I will get my Tahoe to my new residence or when. The dealership was not open on sundays so I had to find a place to stay after leaving my Tahoe full of my items and my bike. I was so afraid it would be broken into. I had an oil pressure warning right before the engine completely stalled. And, I was accelerating up an incline and it felt like my Tahoe couldn't get enough power to make the incline. My Tahoe only has 35,047 miles, and threw the diagnostic trouble code p0016 through my onstar app as well as with the tech at the dealership. And, I am having a lot of trouble with gm corporate with rental cars. I had to pay out of pocket in order to get back on the road with my belongings as I start a new job this week at my new home. I had to leave some belongings and my bike with my Tahoe at the dealership.

I was a victim to the l87 engine loss of propulsion recall. On June 19, 2025, my engine was replaced as it failed all test. After getting a new engine, I have had 5 engine misfires and the dealership blamed it on faulty gas. Now my 2023 Chevrolet Tahoe that I trust to drive my two toddlers around, is at the dealership for a flashing engine light. Even after the engine was initially “remedied”, the new engine continues to fail and I have lost trust in having a safe and reliable vehicle.

When gm announced the recall involving the potential for catastrophic engine failure, I immediately contacted bridgewater Chevrolet in NJ to schedule the required recall inspection. I was told the dealership could not perform the inspection because it had not yet received the required 'diagnostic tool' from gm. Once they received the equipment, they contacted me and on oct 1, 2025, they completed the required recall inspection and informed me that my Tahoe had passed the recall inspection and that the vehicle was safe to continue driving. On xxx while driving over the driscoll bridge on the [xxx] with my daughter and our dog, the engine catastrophically failed without warning as I began to exit on exit [xxx] to [xxx] into heavy traffic. With no warning, the vehicle flashed that it was in neutral and then suddenly lost all power and stopped completely in a traffic lane, creating an extremely dangerous situation. After a few mins, I was able to get it started briefly, enough to coast along to a spot a few hundred feet away where there was a shoulder. From there the wheels locked and it would not move at all and windows would not open. It had to be dragged completely inoperable with locked wheels onto a flatbed three separate times. It was first dragged and flat bedded off the parkway to a place we felt unsafe so we stayed locked in the car in July heat with no windows down, then to my mechanic and then to the dealership. I am unsure of the damage that may have caused. The dealership received the vehicle on xxx and within a day told me that it was indeed what my mechanic and they suspected - the catastrophic failure recall they had inspected and passed the vehicle for. As of today, xxx, I was told they just received an engine and can start a full replacement this week. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Piston ring went bad causing catastrophic engine failure. Now needs new motor. Only had 62k miles. It had been burning oil but was taken to the dealership for maintenance and they didn’t report anything.

Hard shudder when driving between 45 to 50 mph and when you decelerate around 12 to 15 mph. Inspected at lond lewis Chevrolet stated and now being inspected by bentley Chevrolet due to lond lewis Chevrolet doing absolute nothing. Tahoe has 23,000 miles currently. Bought new one owner always serviced as should.

We had car checked due to strange and erratic shifting in less than a year of owning. Then took in for recall, they stated it was fine and performed the remedy with higher grade oil. Still had issues and took to another dealership to look at and they stated it was fine as well. About 2 months later while I was driving it was hesitating and would kind of buck and when I was about to turn on to a busy road it just stopped. I couldn’t do anything at all, the entire car was locked up. The tow truck driver couldn’t even get it into neutral to tow. Dealership said it’s the engine and it needs to be completely replaced.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at 40 mph, a warning message advising to reduce acceleration was displayed, the check engine warning light illuminated, and the vehicle stalled. The contact was able to pull over safely. The contact stated that the failure was recurrent. The dealer was notified of the failure and diagnosed the vehicle with a valve failure. No further information was available. The manufacturer was notified of the failure. The failure mileage was approximately 57,000.

While traveling at 55mph yesterday, I experienced a full engine failure which shut the car off fully while traveling on a single lane double yellow road. I was able to coast to a secure location. The car will not start or go into neutral. There were no warning lights that occurred at any time prior to the failure. This all occurred while on vacation 2 hours away. I previously went to the dealership for the recommended "fix" for the recall but that obviously did not solve the problem. This was an extremely unsafe situation for me and my family. I also encountered towing costs and significant loss of time. In addition, the car is at a dealership over 2 hours from my home. Chevrolet should be held accountable well beyond a recall notice which didnt solve the problem.

We purchase the vehicle in February of 26’. Certified preowned they a Chevrolet dealership. It was disclosed to us that the engine had been recalled and replaced in September of 25’ (had about 1500 miles put on it, before we bought it) due to the ongoing issues that plague the v8 6. 2l motors. We put less than 3000 miles on the vehicle and wanted to take it in for oil change and new tires. My wife had heard a rattling/ticking sound and wanted the dealership’s service department to check it out. They test drove the vehicle and immediately told us that this second engine needed to be replaced with less than 4,500 miles on it. We’ve now had a loaner for almost 7 weeks while we wait for a new 6. 2 liter engine that no one is even sure won’t have the same thing happen to it that the first two engines had happen. Gm needs to correct this issue. I read that over 1100 6. 2 liter engines are on back order. This is unacceptable.

Total engine failure.

Engine stopped while driving 70 mph down the highway and the car shifted into neutral. Had to cost to side of the road. Took car into dealership and even though the car was certified safe drive and the engine had no issues 5 months ago, I was told the engine was now locking up. The engine failed despite using the higher viscosity oil that chevy recommended. These greedy cunts at chevy placed me and my family's lives in danger to save a buck; they knew that the engines would fail and instead of replacing the engines, they put thicker oil in the cars to hopefully get the cars past warranty.

Chevy Tahoe with 6. 2 v-8 engine started making noise. Started rattling. Taken to dealership where I bought it. Oil changed found metal in the oil engine making all sorts of noise. Diagnosed to engine failure. New engine is ordered . It’s been 2 weeks and I am number 5 in order for engine replacement at the dealership.

The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

2023 Tahoe z71 had recently been put in the shop, and evaluated for engine failure recall. Dealership/gm deemed it failed test for replacement, we were given 0w40 oil and sent back out, this last weekend we had catastrophic engine failure while operating at 50+mph.

The engine randomly shut off while driving down the interstate and wouldn’t start back up. The car had the recall “remedy” done to it. Inspection and thicker oil. The only warning I got was to restart the engine after it shut off. My safety was compromised by breaking down on a main interstate coming through memphis with no emergency lane to pull over in.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was previously repaired under NHTSA campaign number: 25v274000 (engine and engine cooling). The oil was changed at the local dealer. After 24 hours, the engine was blown after driving approximately 50 miles. No warning lights were illuminated. While accelerating from a stoplight, there was an abnormal squealing noise from the drivebelt. The vehicle was taken back to the local dealer, and the contact was informed that the flywheel was hitting the camshaft and changing the oil had disturbed the function of the vehicle. The vehicle was not fully diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 14,945.

My 2023 Chevrolet Tahoe (VIN: [xxx]) suffered a catastrophic failure of the 6. 2l v8 l87 engine assembly — specifically the connecting rod and crankshaft components — at freeway speeds on [xxx], just 9 days after purchase. The original failed engine is no longer available for inspection as it was removed and returned as a core by shaheen Chevrolet in lansing, mi as part of the warranty replacement process. The only symptom prior to failure was a brief squeaking noise that began approximately 0. 5 miles before the engine failed. No warning lamps, messages, or other indicators appeared at any point before the failure. The engine then failed suddenly and completely at freeway speed, causing immediate loss of propulsion. My family was left stranded in an unsafe roadside location until a tow truck arrived. Sudden loss of power at freeway speeds creates significant risk of collision for both the vehicle's occupants and surrounding motorists. The failure was inspected and confirmed by shaheen Chevrolet as a gm manufacturing defect involving the connecting rod and crankshaft. No police, insurance representatives, or gm field engineers inspected the vehicle beyond the dealership. Gm authorized a full engine replacement under special coverage warranty (10 years/150,000 miles). The replacement engine (gm part #12740076) was on national backorder for over two months due to supplier capacity constraints. A loaner vehicle was provided during that time. This failure occurred despite a prior gm recall addressing the same rod/crankshaft defect having been performed on this vehicle. The recall remedy was ineffective. I have no confidence the replacement engine will not fail again. With approximately 597,630 vehicles affected, this represents a serious and ongoing public safety risk. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine failure while driving to [xxx] from [xxx] . Mobile mechanic indicated a likely spun bearing. Less than 24,000 miles. Was stranded in [xxx] and delivered vehicle to local Chevrolet dealership same day as incident. It’s been over a month with no repair eta. Incurred significant travel and accommodation costs, with receipts available, due to the disruption. Gm had thus far refused to confirm any reimbursement of expenses. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On April 10th, while traveling approximately 7 hours from home on a very busy highway in [xxx] , my 2023 Chevrolet Tahoe (6. 2l engine) suffered a complete and catastrophic engine failure, requiring a full engine replacement. The vehicle had to be towed and I was left stranded with no transportation. Prior to this failure, I had brought the vehicle to an authorized gm dealership for a recall inspection specifically related to the 6. 2l engine on September 9, 2025 with 36,162 miles. The dealership technician inspected the vehicle and informed me that my engine was not defective and cleared it. Shortly after that inspection, the engine suffered a total failure at 46,6xx miles on the vehicle. I am currently leasing this vehicle at approximately $1,100 per month and have been without the vehicle for an extended period while it sits awaiting repair. Gm customer care has been contracted and has indicated they cannot move forward with a buyback claim because the bbb is not taking my case because the vehicle is older then 2 years old which I know is a false legal claim. This is a serious safety concern, a catastrophic engine failure at highway speed poses significant risk to vehicle occupants and others on the road which appears consistent with other reported failures. I am aware that NHTSA has opened recall query rq26001 investigating the adequacy of gm's remedy under recall 25v-274. My experience is consistent with the 36+ complaints that triggered this investigation, engine failure occurring after an authorized dealer performed the recall inspection and cleared the vehicle. I am requesting this complaint be added to the rq26001 investigation file. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

As I was driving down the tollway in dallas going 75 miles an hour, my engine completely shut down and went into neutral in rush hour traffic. I had to slowly get over from being in the left lane as my car was slowing and slowing. I was able to get over on the side of the tollway as cars zoomed past me. By the grace of god, I didn't get hit. Once it was towed, the service department confirmed that it is my engine that shut down and the entire engine needs to be replaced. Now the problem is they cannot find an engine or parts to fix it. No warning came on at all before this happened. Very dangerous situation.

Passed a truck in 2023 chevy Tahoe on a two lane highway and the Tahoe would not accelerate. It switched into neutral and would not run. This was a major safety issue. There was a semi truck behind me that could have run over me and my family. Luckily there was wide open area next to the road that I coast into. Truck was towed to a dealership out of state while we were on vacation.

My wife just picked up our 4 year old from daycare. She just merged onto I-81n and the vehicle shut off on her at highway speed during rush hour! a message on the dashboard said "please restart vehicle". She managed to pull the Tahoe off onto the shoulder, but couldn't get it started. She remained in the vehicle with my daughter and called 911 to request a state police vehicle park behind her so that she wouldn't be hit by any passing traffic. I (her husband) met her on the side of the highway and we tried starting it with a battery booster pack to no avail. We called a tow truck and had the car towed to the dealership that we purchased the vehicle from. They confirmed that the motor was indeed locked up and needs to be replaced. This vehicle already underwent the 6. 2l recall test and "passed". It was running the 'remedy' 0w-40 oil. This is completely unacceptable.
