general problems of the 2023 Chevrolet Tahoe - part 1

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.

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.

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.

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.

We were driving down the highway at around 77 miles per hour. I noticed that the vehicle chimed as though I initially got into it and needed to start the engine. I saw the dashboard asking me to start the engine. I attempted to start it while we were coasting to a stop, but it wouldn't start. I was able to barely get out of the lane of travel and avoid a collision. I tried to turn off the vehicle and turn it back on but it would not start. It would not even turn over. The vehicle eventually cannibalized the battery because it would never shut off.

1) the engine failed and lost propulsion while driving. It is currently at the dealership where I purchased the vehicle new, so it may be available for inspection upon request. 2) my safety was put at risk because the vehicle lost propulsion while driving. This is a dangerous situation in general. In my case I was able to pull over safely and have it towed to the dealership. 3) the problem is that the engine failed. This can be confirmed by the dealership. 4) this 6. 2l engine was part of the n252494001 recall for specifically the issue of engine failure and loss of propulsion, so it had been inspected by the dealership recently. I brought the vehicle into the dealership for this recall several months ago. Per the recall, they told me that the engine would need to be replaced if it didn't pass the inspection. They performed a pico test, informed me that it passed the test, and changed the oil to 0w-40. It has not been inspected by gm, the police, insurance representatives or others at this time. 5) there were no warning lamps, messages or other symptoms of the problem prior to the failure.

Total engine failure.

The vehicle motor goes out with no indication that anything’s going to happen. It does this a different stages of miles. Mine happened when I was passing someone on the high way. It just shut off.

Our vehicle passed their inspection required test for the engine recall and then at an intersection just died with absolutely no warning and wouldn’t even start again. Warning light for low engine oil came on. We were stuck and couldn’t even put the vehicle in neutral to be towed out of the intersection. Had to call a flat bed tow truck to load it and take to dealership where it was confirmed the engine failed!!! police did show up at the scene to facilitate traffic and the loading of th vehicle.

I took my 2023 chevy Tahoe in for all recall corrections promptly when the notices were received. My last recall was to run a check to see if my motor was one of the defective 6. 2l engines. It was determined it was not and the dealer changed my oil to the new required 0w-40w. Now a month later as I am accelerating on to the freeway ,I am at 65 mph I cross traffic to merge on to a connector bridge and my car rpm's go through the roof and the car starts to slowly lose power. Zero warning lights are on at this point just decreasing power. As I am on the bridge my engine light comes on with a engine oil hot idle engine notice I am now at 35 mph. Then a oil pressure low turn vehicle off notice comes up and we are at 15 mph the car turns off. The screen says press start again but as we do it wont do anything. It then randomly starts turning off and on. We got to a point on the bridge where we could coast to the connecting freeway below and pull over. My car was towed to the dealer where it has been confirmed it needs a new motor with no know eta of the new motor.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was repaired under NHTSA campaign number: 25v274000 (engine and engine cooling) in November 2025 by the local dealer. The contact stated that the engine had passed the inspection, and a higher viscosity oil had been added along with the other steps stated in the recall. The contact stated that while driving approximately 55 mph, the accelerator pedal was depressed; however, the vehicle failed to respond. The gear shift indicator indicated that the transmission had been shifted into neutral(n). The contact attempted to shift to drive(d) when the vehicle stalled. The vehicle was stopped but was unable to restart the vehicle. The vehicle was towed to the same dealer who had completed the recall repair. The dealer diagnosed the vehicle and determined that the engine, starter, radiator, and fuse block needed to be replaced. The vehicle was being repaired. The manufacturer was informed of the failure and a complaint was filed. The failure mileage was approximately 48,000.

To NHTSA, I am reporting a serious safety defect in my 2023 Chevrolet Tahoe purchased from criswell Chevrolet (gaithersburg, MD). Defects include a documented brake system failure while driving and repeated electrical/shift faults preventing shifting out of park. The issue is ongoing even after the dealer/manufacturer stated it was fixed. Key events: Feb 3, ~12:45 while traveling ~35–39 mph on a five?lane road, brakes failed. I slowed by coasting uphill and using maximum pedal force to ~5–7 mph before stopping. I have video of the incident and two other times this has happened with pictures as the car was in park. Three prior start-up incidents: all dash lights illuminated (including brake failure and forward collison system unavailable); vehicle stuck in park. First required towing; dealer could not replicate despite reported stored codes. Subsequent event stranded my family. I have notified Chevrolet and the dealer; their offer does not address safety or recurrence. Please record this complaint, assess broader risk, and advise on related recalls/investigations. If there is a path forward to ensure the safety of my family, please respond with that guidance. My phone number is [xxx] . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2023 Tahoe hc 6. 2l VIN passed the catastrophic engine safety recall stating my engine was safe. The dealership performed a change in oil velocity per gm's directives. Then the engine seized upon accelerating. No warnings, just dead, yet able to coast through a large intersection on a -20f day where nothing worked on the vehicle. Even though the engine would not turn over when hitting the start button, it would only allow 15 minutes worth of emergency flashers before the sensors shut the vehicle completely down. We had to abandon the vehicle on the side of the road, with key fob in this new vehicle, hike to safety, and for warmth. Total mess up as how to tow the vehicle, even when I advised nothing (but siriusxm) worked and could not put vehicle into neutral. Had to wait almost a month for a replacement engine. Once replacement engine installed, I expressed how my vehicle did not feel, nor sound the same as the original. The dealership ensured that it was a 6. 2l engine replacement, without being able to tell me where it came from, how many miles on it, or the serial number to this new engine. I was told to give it 500-1000 miles to allow replacement engine to "settle". Exactly 300 miles in, on the expressway, just coming out of a bottle neck slowdown, I got up to around 45-50 mph and it was like I hit an invisible wall! vehicle lost propulsion. Seat belts locked. No brake lights since I was accelerating. Extremely thankful nobody was behind me. Obviously let go of the gas. Pause. Then I was able to drive the vehicle to a safe location off of the expressway, and shut it down. Immediately called dealer. Restarted, drove about 15 miles to safety, went to shut off and it would not turn off. Sounded as if trying to start it while already running. 20 min to turn off. 5 months at dealer, they could not mimic/see any issues, even though I could "feel" the loss of propulsion at lower speeds. Fearing all lives, I had to trade down yet more $.

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.

Truck bucked twice in high-speed lane of the highway, gas pedal went soft and we luckily were able to coast the truck to the side of the highway without getting hit. The truck put itself in neutral when we lost the engine and the truck would not restart. It had to be towed, while me and my two kids stood on the side of a dangerous highway for 45 minutes in the snow. The truck has 52,000 miles, engine was already replaced at 10,000 miles. It just passed the recall inspection and had the upgraded oil that was recommended.
