general problems of the 2023 Chevrolet Tahoe - part 2

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.

Engine failure resulting in new 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.

While driving to my appointments via the freeway, all of a sudden the vehicle slowed down, I noticed most of the warning lights were on including the check engine light that was blinking. I happened to be near a GMC dealership which previously did repair work on my vehicle and left it with their service center for a diagnostic inspection. A week later my service advisor contacted me with their vehicle condition report that my vehicle had camshaft and internal engine group issues. He quoted repairs but recommended replacing the engine. Repair or engine replacement $21,296. 51. Six months before this issue I had the same issue the warning lights and it resorted in replacing the brake control cylinder. Once repaired no issues/messages or symptoms with my vehicle until this current engine problem/replacement.

As the owner of a 2023 Chevrolet Tahoe, I am currently experiencing persistent issues with the instrument cluster going dark and a severely malfunctioning gm 6. 2l l87 engine. In November of the previous year, I encountered a sudden and alarming loss of engine power while traveling on a multilane highway at a speed of 70 mph. I successfully maneuvered the vehicle to a narrow shoulder, where I remained, accompanied by a highway patrol officer, for over three hours until a tow truck arrived. The gm certified dealership informed me that the engine was seized. The mechanics were unable to start or manually turn the engine. Upon removal of the engine’s oil pan, they found metal fragments in the oil. After having undergone an engine recall “fix” three months earlier, which included an inspection and oil service change to a more viscous 0w - 40, a new oil filter, and a new filler cap; in November, my engine failed and was replaced with a new 6. 2l l87 engine. Initially, I was pleased with the repair, but I have since lost confidence that my car is safe after the new engine began exhibiting symptoms of a pending failure. The Tahoe hesitates on acceleration when merging with highway traffic, the engine dies when decelerating, the check engine light flashes at highway speeds, and the instrument cluster turns off at random. The vehicle that has been outfitted with a brand new engine is currently at the Chevrolet dealership; however, just like in August of 2025 during the recall inspection, the mechanics there were unable to find any problems with their work or the new engine. They simply erased the stored p0300 engine diagnostics codes and ignored my evidence video, which showed the check engine light blinking at highway speeds. Despite the repair attempts, the issues have not been resolved, and the vehicle continues to pose a safety hazard.

I dont believe the correct fix is changing oil viscocity.

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.

I bought this 2023 chevy Tahoe rst brand new from the dealer and about a few months of owning it I noticed that the truck was needing oil before the next oil change. It’s as if it was consuming itself. This continues for month until last week when the truck died on me. I was able to jump start and everything worked fine for a day. The next day things got worse. I was on the highway and truck started shaking and giving off all kinds of codes. I took it to dealer and they said I needed a new battery but that there was also an engine problem. I bought a new battery and none of the messages on dash resolved like I was told. The truck is u drivable motor is knocking and was even making loud popping sounds. Of course my truck just hit 64,000 miles so gm is saying I’m out of warranty. I should not be having these types of issues on an almost brand new truck that I’ve owned 2 years. Engine light is flashing and dealer said this means major issue.

2nd powertrain failure in 4 months in 2023 Tahoe with 6. 2l engine. The first being the camshaft and lifters failing at highway speeds, which was repaired. The second issue the engine seized while on a tollway going approx 70 mph with my spouse, children, and family in the vehicle. We were able to coast to the shoulder while waiting on a tow truck. Because of the engine being seized, the Tahoe is waiting on the engine to be replaced. While we wait, we were told they have no loaner vehicles and there are no gm rental vehicles available with who they contract through. Having a 2023 leased vehicle fail twice in 4 months with children in the vehicle is unacceptable and brings to question the safety and reliability of the vehicle moving foreward.

The engine in my vehicle has experiences major failures in valve flap adjusters, multiple valve failures, valve cover issues, and over consumption of oil by over a quarter in a week and a half of average driving. My safety was put at risk because the engine failure resulted in traction control malfunctions while going 70 mph up hill on a major interstate. This led to extreme shaking which did not stop until slowing down to below 15 mph. Luckily I was a mile from an exit and was able to coast off the road quickly; it was decent enough weather, and I was less than 5 miles from my destination so I could creep between 15-30 mph to not exacerbate traction control alarms. That slow mph did back up traffic behind me. As far as I am aware the problem was likely reproduced by the dealership service tech, which led to their recommendation to replace the whole engine. They do not consider it to be covered by any warranty anymore. The engine may be in their possession still, but I am unsure. There were zero warning lights/prompts from the vehicle that anything was going wrong prior to the shaking and loss of traction control at high speed. The dealer service team suggested that my high miles led to the engine failure. I do highway driving with it and have followed all manufacturer recommendations for oil changes, and even more frequent changes with oem oil since about 80k miles. I do not think this engine should have failed at this amount of mileage. I made note of oil consumption around 95k miles and measured oil loss regularly. It was a little less than a quart every 2k to 3k miles which manufacturer states is within spec so I would top off oil. A year ago it had a tcm wire replaced after burning in half. 3 weeks ago I also had to replace the entire turbo. The wire rendered my car unable to go in gear. The turbo failure put me into limp mode. I think the turbo failure was a sign of a deeper issue that went undiagnosed.

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.

At a stoplight vehicle wanted to stall out motor was shaking.

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.

While traveling on the highway, the vehicle suddenly lost all power. The gas pedal became unresponsive, and the engine ceased functioning entirely—without any prior warning or indicators. I was forced to coast into a nearby parking lot to prevent a potential collision. This incident put both myself and my child at serious risk of injury or worse, had it occurred at a higher speed or in heavier traffic. Once stopped, the vehicle would not restart. I had no choice but to have it towed to the dealership for evaluation. A week later, the dealership diagnosed the issue as a locked-up engine, confirming that a full engine replacement is necessary. Unfortunately, the replacement engine is currently on backorder, and they are unable to provide an estimated time of arrival. To make matters worse, the dealership has no loaner vehicles available for at least a month. Gm only offers a rental reimbursement of $44 per day, which is significantly below the cost of even a basic rental vehicle in our area ($74/day). This leaves me with limited transportation options, even though I am currently making monthly payments of over $1,400 on a vehicle that is completely unusable. Adding to the severity of this situation, the vehicle is also subject to a manufacturer recall, but no remedy or parts are currently available to resolve the issue. As a parent of multiple children, this entire experience has left me shaken. I cannot begin to imagine the consequences had this failure happened at a higher speed or in less forgiving conditions. I am extremely concerned for my family’s safety going forward. Gm has stated they will not extend or provide additional warranty coverage until the repair is complete, which leaves me feeling unprotected and anxious about the future reliability of this vehicle. The absence of warning signs and the total loss of power while driving make this a critical safety concern that must be addressed. I urge NHTSA to hold the manufacturer accountable.

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.

My vehicle’s engine has been recalled since June. The dealer refused to inspect because there is no remedy to replace the engine. I have complained since I purchased the vehicle of noises that I’ve heard. I am hearing more noises, and I am increasingly getting more scared every day to drive my vehicle. I will not put myself nor my family in harms way I can get into an accident. I am afraid to drive the vehicle. I am not taking any chances of hurting anyone else or my family or potentially have a fatal accident. Two months of driving around scared I will not drive my truck anymore. I am beyond upset that there is no remedy for this and that it is not taken seriously. Something needs to be done regarding my situation and all others. The vehicle was sold, most likely knowing that this was a problem. Gm needs to make good on this problem before people get killed. I would like them to buy back my vehicle, I am sure I qualify for a full re-purchase. I called gm. They will get back to me in five business days. I cannot emphasize how afraid I am to drive my vehicle and I paid $110,000 for this vehicle.

Unusual knocking noises, performance issues, high rpm, - traction control light is on feels at times the engine is on verge of losing power while I'm driving on the highway with my children and I could get hit check engine light blinking constantly.

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.

2023 Tahoe with 6. 2l gas engine at 29k miles suffered a complete engine failure on a major road at 60mph with no prior warning. We were lucky to be able to get it out of the road safely but it stranded my family. It’s currently at gm dealer waiting for an engine replacement.

I filled my car up with gas and turned it on and it started shaking. Several warnings popped up on the dashboard screen including, service esc, service traction control, and forward collision system unavailable. My cruise control was disabled I had to hold my foot at an angle to keep the speed at 45-50 mph, causing it to take 10 hours for me to get home from austin to dallas. The check engine light was on the entire time and flashed for the last hour to hour and a half. I was unable to pull over at that time because it was dark and I was in the middle of nowhere by myself. The next day I turned my car on. The only thing on was the check engine light, is , however , around 1 pm that day it started doing the same thing. I drove it from my patient's house in allen to galleria Chevrolet in dallas. They told me my battery was too low to run diagnostics and I needed to replace it. So I bought a battery and brought it to them. They replaced the next morning and told me there were no codes showing up so there was nothing wrong with my car and it was a fluke. Exactly one week later the same thing happened to my car. I called the dealership and they hao it toewd to the service dept. After I repeatedly called them to check on the status of my car, they told me it was the fuel injector #1. They then were able to apply for a loaner car for me as I am a hospice nurse. These are same exact issues that the gm 6. 2 l engines are having with the recall they just announced. I have a 5. 3 l engine. I am afraid to put my kids in my car. Please help get gm to take responsibility for this!.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at 75 mph, the vehicle shut off without warning. Due to the failure, the contact used excessive force to steer the vehicle off to the shoulder of the highway where the vehicle was then towed to a dealer. After the vehicle remained in the dealer's possession for over a week, the vehicle was diagnosed with an engine failure. The contact was then informed that the vehicle was placed under recall NHTSA campaign number: 25v274000 (engine) and that the engine would be replaced. Despite the engine repair, the contact stated that an abnormal, rattling sound would emit from the vehicle upon start of the engine. In addition, the contact stated that the vehicle would violently jerk upon depression of the accelerator pedal while at a complete stop. The failure started intermittently; however, the contact stated that overtime the failure became more persistent. The vehicle was taken to the dealer where they claimed that the transmission was four quarts low on transmission fluid; they then informed the contact that they could not guarantee that remedy would repair the failure. The contact stated that failure improved; however, she would still experience a slight hesitation upon depression of the accelerator pedal. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 39,000.

We were driving on a busy interstate in knoxville, TN on a Sunday. We were 2 hours from home and my 2023 Tahoe basically went into limp mode while I was in the fast lane and the check engine light came on. No warning in advance. The speed reduced, which backed traffic up, and put me and my 4 children in danger. We finally got off the interstate and the vehicle had to be towed in to the nearest dealership. I had a friend drive us to enterprise where they put us in a Jeep grand wagoneer. On Monday, I received a call from the dealership stating they had good and bad news. The good news was the repair is covered by warranty but the bad news was it will be 2-3 months before they can get the part. The part is on back order and several people are waiting ahead of me. The said part is a valve body for the engine/transmission. The dealership also informed me that warranty will not cover a non-gm vehicle and that they will only pay for a rental up to 44. 00/day. It’s not my fault the part is on back order, nor that enterprise gave me a non-gm vehicle. Also, I have a family of 6, which is why I have a Tahoe and I cannot be put in a small sedan. My children play sports, we have upcoming vacation, and quite frankly, I didn't pay 90,000. 00 for a vehicle to be placed in a vehicle that I don’t feel is safe for my family. If I had wanted a sedan, I would have bought one. Gm should take better care of their customers, especially when something is like this is not the customers fault!!! I have contacted gm and have been told I will be called back by a supervisor each time I talk to someone. This is unacceptable!!.

The engine stoped running at about 50mph. Beatty Chevrolet in knoxville TN has car suddenl deceleration no brake lights and stuck on curvy [xxx] engine is lockedup and beaty ordered a new engine with gm approval beaty Chevrolet inspected the engine the only message was push start again. The service dept rep said this is rare but had 5 6. 2l engines affected at his shop. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.
