Engine And Engine Cooling Problems of Chevrolet Tahoe - part 1

Low oil life notification on phone. Since l87 recall, an oil consumption test was stopped and the new type of oil has been added to the vehicle 5k miles ago. Had to add a full quart to register on dip stick. Will now start another oil consumption test with a dealership. I am very concerned about my families safety.

We just recently had the cam shaft and lifters replaced, as the vehicle began experiencing a knocking sound. The repair was supposedly completed, and they gave the truck back. We took the truck back in within a week, bc we continued to hear the sound. They sent it back saying they didn’t hear anything after test driving it. Over the weekend the car shut off after beginning to shake uncontrollably. Now supposedly the camshaft bearing is gone, and the truck experience engine failure. I spoke with someone previously, as the issue being repaired hundred thousands of cars were recalled for the same issue. I was told that it wasn’t on the same line, even though my truck was experiencing the exact issue and fell under the years. We were placed back on the road with our family, with a vehicle.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while having a routine oil change at a local dealer, the contact was informed that the engine was blown. No warning light was illuminated. In addition, upon further notice, the contact's husband heard an abnormal clicking sound coming from under the hood. The vehicle was diagnosed, and determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was made aware of the failure. The failure mileage was approximately 84,000.

I drive a 2021 Chevrolet Tahoe. This occurrence has happened on three separate occasions and each time it was raining outside. The first occurrence, my vehicle was running and parked in the rain after driving approximately 5 miles. While parked my check engine light came on with a series of warnings: service ecs, service traction control, forward collision system unavailable, reduced acceleration drive with care. Two days later it went away. The second occurrence, I was driving in the rain for approximately 22 miles and briefly parked with my vehicle running. I then turned out of a parking lot and began to accelerate to speed up and the check engine light came on along with all the same messages, this time my vehicle acceleration had seized and wouldn’t go faster than 30 mph. I slowly drove back to the parking lot and turned the vehicle off to let it sit, disconnected the battery and reconnected, and the issues went away. The third occurrence, I was driving on the highway in the rain for approximately 10 miles, I went to merge into a right hand lane, I took my foot off the acceleration peddle to slow down for the merge and as I slightly turned the wheel to the right, my vehicle spun out three times, throwing the back end of the Tahoe into the inner highway wall, which spun me again to face the right direction, next to a highway exit. I then went to accelerate to exit the highway but noticed my vehicle would only coast and realized my engine had cut out at some point. I started the vehicle and exited the highway and parked in a parking lot only feet away from the exit. After I parked I noticed all the same warning lights came back on. Each occurrence happened on [xxx], [xxx], [xxx]. My vehicle was towed to gunn GMC collision center in selma, TX and will be looked at on September 3, 2025 around 8:00am.

2021 to 2024 has had countless problems with the 6. 2l engine. General motors has put a stop of sale on vehicles with this engine. When I purchased the car the wrong oil was in the car which always burned off with 2 months after an oil change. They figured out the right oil but the damage has already been done.

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 driving the car just stops losing power then the car immediately shuts down and stops driving. I had to call a tow truck when it’s taken to the dealership the fuel pump power control module is faulty. This is a 2021 Tahoe they had to replace the fuel pump, power control module, and this vehicle should not have to be replaced. Chevrolet/GMC knows that these modules will make the vehicle stop wherever it is driving. I happen to be on a freeway going 70 mph and could have been killed. They have not put a recall out to have these modules replaced in any SUV. This is a danger for any driver on the road. This is a lawsuit waiting to happen for people. You know that they are aware this is happening because they paid for the tow and replaced this part that is not warranty now for free. Yes, great that it was paid for but thankful I did not lose my life as I could’ve been rear ended when my car shut down going that fast in the middle of the freeway I am begging that they please put a recall so no one gets injured or killed.

I am writing to formally document serious engine defects I have experienced with my 2021 Chevrolet Tahoe equipped with the 5. 3l l84 v8 engine. 1. Crankshaft failure omy Tahoe suffered a catastrophic crankshaft failure that required major repair/replacement. Oi am aware that gm has recalled certain vehicles equipped with the 6. 2l l87 engine for crankshaft and rod-bearing defects. Obased on my experience, the same or a very similar defect has also occurred in my 5. 3l engine, which is currently not included in that recall. 2. Valve lifter failure oin addition, my vehicle has suffered from valve lifter collapse—a well-documented problem in 2021–2022 gm trucks and suvs with both the 5. 3l and 6. 2l engines. Othis caused severe misfiring, drivability issues, and expensive repair needs. Why this is a concern: •both failures occurred well before what would be expected of a modern engine. •the crankshaft failure raises a safety risk: sudden loss of propulsion while driving could lead to accidents. •the lifter issue is widely reported by other owners and has been the subject of gm service bulletins. •taken together, these problems suggest systemic defects in the 2021 Tahoe’s 5. 3l engine that have not been adequately addressed by gm. Requested action: •I ask gm to extend recall and warranty coverage to include the 5. 3l l84 engine in addition to the 6. 2l l87. •I ask NHTSA to consider investigating whether the scope of the current 6. 2l recall should be broadened to include 5. 3l engines, given failures like mine. •at minimum, I request assistance in covering repair/replacement costs for both the crankshaft and lifter defects, which are clearly not due to normal wear and tear. Vehicle details: •year/make/model: 2021 Chevrolet Tahoe •engine: 5. 3l v8 l84.

The contact owns a 2021 Chevrolet Tahoe. While driving 25 mph, the vehicle stalled in the street. The vehicle was eventually restarted and was driven to the family’s residence. After arriving at the residence, the vehicle failed to restart. The contact stated that the failure was like the failure in NHTSA campaign number 25v274000 (engine and engine cooling). There were no warning lights illuminated. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA hotline for assistance. The approximate failure mileage was 73,000.

To whom it may concern, I am writing to formally report serious defects with my 2021 Chevrolet Tahoe (VIN: [xxx] ) and to request assistance with repair costs. Approximately six months after purchase, when the vehicle had about 22,000 miles (I bought it used with around 19,000 miles), the battery and electrical system failed. I brought it to the dealer and was told there was no issue; they only performed a jump start. Two days later, the vehicle broke down in the middle of the road. I had to pay for a tow truck and replace the battery completely out of pocket. More recently, at about 92,000 miles, the vehicle developed severe engine problems. A certified mechanic diagnosed collapsed afm lifters and camshaft damage. The repair requires oem gm parts and costs approximately $4,500. This issue is widely reported by other gm owners with 5. 3l afm engines and is known to be a manufacturing defect, not a maintenance problem. Please note that my Tahoe has been well maintained, with oil changes always performed on time and using the correct oil and service intervals recommended by gm. Despite this, the vehicle has experienced repeated and costly failures that create unsafe driving conditions. I kindly request that gm review my case and provide assistance with covering the repair costs or reimbursement, given that these issues are the result of known defects and not owner neglect. I look forward to your prompt response. Sincerely, [xxx] [xxx] 33032 [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Loss of power.

While driving on the expressway I heard a rattling noise coming from my undercarriage, by the time I got off my exit the sound got louder, I attempted to make it home and when I pulled in my driveway, and popped the hood, fluid starting pouring out the bottom as well as splashed on other components. Upon further inspection it was determined that the fluid was coolant. There was no dashboards lights or warning signs indicating that something was wrong or that my car was at risk of overheating. I had the vehicle towed to an auto repair shop and the following was diagnosed and repaired: •water pump •cooling system •engine water pump •engine coolant thermostat housing assembly. •serpentine belt.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while his wife was attempting to start the vehicle, the engine failed to turn over as intended. No warning light was illuminated. Upon further inspection, the contact stated that there was an abnormal sound coming from the vehicle. The contact used an obd-2 diagnostic scanner and retrieved dtc: p129f and u18a2. The vehicle was towed to a local dealer, where it remained for further investigation. The contact related the failure to an unknown recall; however, the VIN was not under recall. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 82,000.

The contact owns a 2024 Chevrolet Tahoe. The contact received notification of NHTSA campaign number: 25v274000 (engine and engine cooling); however, the part to do the recall repair was not yet available. The contact was concerned about parts availability and that the vehicle could experience engine failure due to parts not being available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had received the notification in April 2025. The manufacturer was made aware of the issue but provided no assistance. The contact had not experienced a failure.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at 60 mph, the vehicle briefly lost motive power but quickly returned to normal functionality. Later, upon starting the vehicle the engine almost immediately shut off and was unable to restart. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the engine after observing metal shavings in the oil pan. The contact was informed that the engine needed to be replaced. After investigating the failure, the contact related the failure to NHTSA campaign number: 25v274000 (engine and engine cooling). The manufacturer was not notified of the failure. The failure mileage was 100,000.

I am submitting this complaint regarding my 2021 Chevrolet Tahoe (VIN: [xxx] ) which has developed a severe transmission shudder at both low and highway speeds. The issue has been confirmed by my Chevrolet dealer, who provided an estimate of $5,492. 18 for torque converter and valve body replacement. This failure is identical to the torque converter shudder problem documented in gm service bulletins and special coverage adjustments for other gm vehicles of the same make, model, and model year. However, my VIN is not currently included in those programs, leaving me without coverage despite experiencing the exact same defect. I believe this condition poses a serious safety risk, as the shudder occurs while driving at highway speeds, causing vibration, hesitation, and potential loss of control. These symptoms could lead to accidents if the vehicle fails to respond properly during acceleration or lane changes. Given that this appears to be a widespread defect affecting multiple gm vehicles, I respectfully request that NHTSA investigate and consider expanding any related recall or special coverage programs to include affected vins such as mine. Please let me know if further documentation, service records, or dealer estimates are needed to support my complaint. Thank you for your time and for working to ensure vehicle safety.

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.

Car stopped while in motion, engine shutdown and could not be put into neutral to move vehicle out of traffic. Car had to be towed away. Only 37 k miles. This is the second time this has happened in traffic posing a major safety hazard. Fuel control module was what shut down the car while driving the first time. Now it has failed again.

I was driving down I-635 (dallas) at 70mph on Friday 7/25 when my Tahoe started shaking, knocking and had complete engine failure. I managed to regain control and slow to the service road. Thankfully the car next to me was paying attention & swerved to avoid me, but honked at me the entire time. The vehicle was towed and we are being told we need to replace the engine for $14,500. As I’ve researched, the 6. 2l is recalled for this exact issue. The 5. 3l has no current recall but I’m clearly experiencing the same engine failure and being told I’m responsible for it. I had no prior warnings & have regularly maintained this vehicle. Any chance others have complained about the 5. 3l as well & our Tahoe’s should be included in this recall?.

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

Engine starting banging loudly and misfiring. There was a loss of power and engine codes. Brought to the dealer and they said cylinder #4 was misfiring due to a stuck lifter, bent push rod and destoyed cam. Total cost of repair was $9200. Vehicle is less than 4 years old an has 75,000 miles on it.

The contact owns a 2022 Chevrolet Tahoe. The contact stated while driving 70 mph, the vehicle lost power in the middle of the roadway. The contact was unable to pull over to the shoulder of the roadway with the rear wheels seized. The “service transmission” warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the front brakes. The vehicle was repaired, but the failure reoccurred. The vehicle was towed back to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired.

I was driving at a normal speed with my family in the car my son has neck pain since that date and the car just turned off I almost got rear ended and didn’t want to start.

Lifter failure and camshaft failure. Found metal in engine oil that has caused bearing failure and engine damage. While driving the Tahoe on [xxx] I experience a jolt on the front right side. Then warning messages regarding the traction control and to service the esc appeared. As I cleared those messages my engine light was blinking and several other dash lights were lit up. There was a knocking sound. I contacted the dealership (coyle Chevrolet in clarksville, in) and they sent a tow truck to bring it in. They assumed it would be in the recall but it is not. I am without a vehicle and the engine is backordered. It's not right that gm is picking which engines they are going to include in the recall when they know there is a manufacturing issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On 01/03/24, the vehicle stalled and smoked on the suncoast parkway. All dashboard warning lights and messages illuminated, and the vehicle entered emergency park mode. Onstar was contacted and the vehicle was towed to jenkins Chevrolet in homosassa, FL. The failure was linked to a broken pulley and belt system that damaged the ecm and wiring harness. No dtcs were pulled, and mileage in/out was 80042/80043—no test drive performed. On 08/06/24, the vehicle returned to jenkins for a roaring noise. A pulley bearing was replaced, possibly related to the earlier failure. Again, no drivability evaluation or codes recorded. On 03/09/25, the same full system warning lights/messages appeared again. The vehicle experienced harsh shifting and delayed acceleration. It was taken to autonation Chevrolet south clearwater on 03/10/25. Dtcs (p0700, p0717, p2714, p2716, p0706, and u-codes) were found but dismissed. Only the battery was replaced. Mileage in/out was 99494—no test drive performed despite claims one occurred. On 07/08/25, the vehicle again showed full dashboard warnings. Brought back to autonation on 07/09/25. On 07/14/25, customer received a $9,177. 85 estimate including full transmission replacement. Safety was at risk due to repeated stalling, loss of acceleration, and emergency parking mode while driving or merging. These failures could have led to accidents or left the vehicle disabled in traffic. Driver and children were present during each incident. The vehicle is enrolled in onstar and the mychevy app, which provide monthly health reports. Despite these incidents, no faults or warnings were ever shown in the reports. Vehicle remains available for inspection. A case is open with gm. Across 4 service visits, gm-certified dealerships failed to follow proper protocols, including code checks, drivability assessments, and test drives—contributing to delayed diagnosis of transmission failure.

The affected components are the electrical system, engine, and power train. In March 2025, my 2021 Chevrolet Tahoe displayed multiple warning lamps across the dash, including traction control and check engine lights. The vehicle shifted erratically and sometimes entered limp mode. I brought the vehicle to autonation Chevrolet south clearwater for inspection. The dealer replaced the battery, dismissed my concerns, and stated that a test drive was performed, but the mileage in and out on the invoice was identical, showing it never actually occurred. Diagnostic trouble codes (p0700, p0717, p2714, p2716, p0706, and multiple u-codes) were present but were not fully investigated. A gm technical service bulletin (21-na-149, December 2022) covers these exact symptoms (caused by engine wiring harness chafing), but it was never referenced or applied. Because the problem was not addressed, the condition worsened. By July 2025, the vehicle suffered a complete transmission failure. At that point, the dealer confirmed the issue, documenting transmission slipping, shuddering, noise, and additional codes (p0700, p077c, p17f6, p17fb, p1872). Gm increased its goodwill contribution from 15% to 40% of the $9,925 repair cost, while autonation offered only $500 despite their role in the missed diagnosis. Safety risk: my family and I were at risk each time the vehicle stalled, lost power, or shifted erratically while driving, including at highway speeds. These failures created a significant risk of collision. The drivability problem was not properly confirmed in March 2025 despite multiple codes being present. By July 2025, the dealer acknowledged and confirmed the transmission failure. The vehicle remains available for inspection, and I have retained all invoices, diagnostic reports, and communications with gm and the dealership.

The affected systems are the power train, engine, and electrical. My 2021 Chevrolet Tahoe experienced failures consistent with gm technical service bulletin 21-na-149 (engine wiring harness chafing) and the conditions outlined in recall n232404190 (valve body failure, November 2024). Beginning in March 2025, the vehicle displayed warning lights and messages including check engine, traction control, service transmission, and limp mode (reduced acceleration – drive with care). The vehicle shifted erratically, lost power, and occasionally failed to accelerate, creating a serious safety hazard at highway speeds. These problems were documented at autonation Chevrolet south clearwater, where multiple diagnostic trouble codes (p0700, p0717, p2714, p2716, p0706, and u-codes) were recorded but not properly investigated. No test drive was performed despite being claimed by the service technician, and the applicable TSB was not referenced. By July 2025, the condition worsened into a complete transmission failure, with additional codes (p0700, p077c, p17f6, p17fb, p1872). The dealer’s estimate required a full transmission replacement at nearly $10,000. Gm reviewed the case through its internal policy evaluation tool and increased goodwill assistance from 15% to 40%, while autonation contributed only $500. Gm’s partial contribution confirms the defect is recognized, yet this VIN remains excluded from the official recall. This issue placed my family and other motorists at significant risk, as sudden loss of power and shifting failures occurred during normal driving conditions. Dealer records, gm documentation, and photographs of warning messages are available. I request that NHTSA expand recall n232404190 to include affected vins such as mine, since the symptoms, diagnostic codes, and confirmed failures match exactly what gm has already identified as a known safety issue.
