  I was starting to accelerate to a higher level of speed onto the highway; 55 mph going up a hill. I was unable to accelerate much as I pushed on the gas, however the RPM's would get higher. while I was at 45 mpg the RPM's were at 3.5. All of sudden my service engine light came on. I knew something was wrong. Turned around took my car back home very slowly, had my husband come look at my car, who has mechanical experience. Transmission fluid is dark and gritty; when its suppose to be a red in color and smooth. I am now needing to replace a transmission in a vehicle that is 5 years old. How is this possible? I have owned the car for 2 years. Why has these not been recalled yet? Why has these not been looked into further? We are paying a lot of money for these vehicles to turn around and put a new transmission, which isn't cheap into a vehicle that is 5 years old. Any assistance to look into these complaints would be very helpful. I am just glad no one was hurt and I was able to get my vehicle home safely. I keep up with all of the routine maintenance of this vehicle on a regular basis.

• 11/05/2021· AIR BAGS

  In August 2021 I got a system light for a Saftey Restraint System, aka airbag issue. This system was going on and off sometimes as little as 5 seconds apart and then sometimes would go off for a bit then back on. I live on an Island and there is no dealer here I had to buy somewhere else. There is a mechanic here that does work on vehicles and per the dealership, I bought the car from I was told if the mechanic there can do a software update which is what he thought the problem was, then I should do that. I took this advice and did it. When we drove off the light was off and fixed for about 30 minutes, then the light and safety restrain error came back on. This time remaining on. I took it back to the mechanic and got two error codes. I have since tried to contact GM and been dealing with them for 3 weeks with no assurances if I pay to get my car to a dealship to fix I would get my money back for their error. I also came across and article about investigations into 750k 2020 & 2021 GM models including 2020 Chevy Tahoe for airbags not working. As a consumer, I should have the right to be able to be reimbursed for costs accruded to me to get my vehicle where I'm forced to get it fixed.

  I was driving in traffic with 8 kids from my football team on a busy street and my truck start jerking and wouldn’t accelerate much. I was going 35 mph and the truck just slows down in the middle of driving. Then as I pulled over thick white smoke comes from the tail pipe. Thank god it was a Sunday and the busy street wasn’t as busy and I was able to pull over safely because this happen while I was driving. I got the truck to autozone and they gave me a misfire code in cylinder 1. I sent my truck to dealership and spoke with them on the phone and they was able to tell me everything going on with my truck without even having to tell them all the issues happening. They looked at the truck and said I had an internal engine issue. I was advised this a well known problem with my type of truck. I reached out to Gm and asked them why haven’t it been a recall on my truck if this is a well known issue with my vehicle after talking with many mechanics. No answer was specifically provided. I’ve been trying to get them to do what’s right and repair the engine but I’m getting the run around. I’ve reached out to over 5 mechanics and a shops and have been told this is a well known problem was trying to see the cost. Once I found out this was well known it made me contact General Motors. I don’t think it’s fair this is a known issue with 5.3L engine and it hasn’t been a recall. It is unsafe to be driving and the engine just fails on you in the middle of traffic. What if I was on the freeway? My truck is at a Gm dealership right now and Gm and the dealership is refusing cost assistance on a well known engine failure problem. These vehicles need a recall on them that would of been 9 lives at risk because this problem hasn’t been addressed by the manufacturer it was scary when it happen because I was on a busy street.

• 09/30/2025· FUEL/PROPULSION SYSTEM

  Driving long distance from Florida to New York and in VA, experienced a check engine light after fueling. Vehicle started, stalled and trembling excessively. It was taken to the Chevrolet dealership across from the gas station (total luck). It was diagnosed after 1 day in the shop that all 8 fuel injectors and the two fuel rails were corroded and had snapped upon inspection.( photos were sent to me). Vehicle could not be driven. If stall would have occurred while driving on the interstate at speed of 70 -75 mph, the potential for a major car accident with other fast moving vehicles was totally possible. I had to remain in a hotel for 3 days as the dealer had indicated that the parts were on back order because this was a recurring issue in the Tahoe/Suburban/Silverado L87 6.2 HP engine. I rented a vehicle to drive back to NY and got my truck back 14 days later after paying for it ($4600) as GM stated that they could not honor the 5 year/60K warranty despite my truck having 52, 182 miles and less then 5 years because they went by the build date of the vehicle which was March 14, 2020 to March 14, 2025, not the calendar year.

  The 6.2L L87 V8 engine in my 2020 Chevrolet Tahoe Premier RST suffered a catastrophic internal component failure while operating. The engine experienced a sudden, severe internal mechanical breakdown involving the crankshaft or connecting rod bearings, completely disabling the powertrain.This failure causes an immediate and dangerous loss of vehicle propulsion, creating a severe safety hazard on public roads.General Motors has already issued Safety Recall N252494001 (NHTSA Campaign 24V924000) for identical L87 engine bearing failures, but has arbitrarily limited the scope to 2021–2024 model years. My 2020 vehicle uses the exact same L87 engine family and has suffered the exact same catastrophic defect.I am filing this report to urge the NHTSA to expand its current Engineering Analysis (RQ26001) and force General Motors to expand the safety recall to include 2020 model year vehicles before more consumers experience sudden engine failure while driving."

  Chevrolet has a recall on some vehicles for a bad transmission valve body, but my vehicle isn’t a part of the recall and I’m having the exact same issues. Currently my only vehicle that I have to transport my 7 month old is a complete safety risk. My check engine light is on and the code its throwing is to replace transmission valve body assembly. My Tahoe is shifting very harshly when driving normally, it feels like it slams into gears causing the whole car to jerk. When sitting at a red light that turns green, Tahoe is slipping, barely wanting to move through an intersection with vehicles all around me. I’ve been advised to not drive my Tahoe at all because if I do I will certainly have severe drivetrain damage and rear wheel lock up. Like I said, Chevrolet already has a recall for this issue on some of their vehicles, but my specific Tahoe does not. This is my only vehicle for myself and my baby and I cannot drive it due to its safety issues.

  My engine light keeps coming on randomly. When this occurs, the dashboard lights blinks and I get a " steering assist" error message. Once this happens it is really hard for me to steer AND I lose acceleration as well. Imagine losing acceleration in the middle of an intersection. Also, I noticed my temperature gauge moves up & down as well. I have taken it to the dealership each time it happens and they are saying they haven't been able to replicate the issue. The engine light only stays on for a few hours or days and the problem goes away once the engine light is off. From my research, this was the same exact problems the 2015 Chevy Tahoes had as well. I don't understand why they cannot figure why I am having this issue. The engine light errors code listed alot of issues yet they still can't diagnose a problem. They have updated the system and checked all wire connections per the dealership. This is my third or fourth time complaining about this issue and this is the dealership's third or fourth time trying to diagnose the problem but they keep telling me they can't.

After visiting the internet I then saw other complaints about the module on the dash for the trailer brake adjustment having repeated complaints. I have never used the 2020 Chevy Tahoe to tow a trailer that had its own braking system. The only thing I have towed was a small U-Haul Trailer.

• 04/25/2026· SERVICE BRAKES

  I own a 2020 Tahoe, 160,000 miles. While driving, the vehicle experienced a sudden loss of brake assist due to a failure of the vacuum brake pump. The brake pedal became extremely hard, and the vehicle would not slow or stop as expected, requiring me to put vehicle in neutral and frantically find a way to the shoulder to force a stop (pulling the emergency brake). This created a dangerous condition and significantly increased stopping distance, posing a serious safety risk to myself, and others on the road. There was little to no warning prior to the failure. This issue appears to be consistent with known complaints involving vacuum pump failure and loss of brake assist in similar vehicles. A failure of the braking assist system is NOT a normal wear condition and presents a critical safety hazard. I am reporting this incident due to the safety risk associated with sudden brake assist failure and the potential for accidents or injury. Vehicle issue has been confirmed by an independent service center. There was a warning light that appeared at the same time the brake stopped working leaving me no time to plan or know ahead not to drive.

  On June 17th, 2025 while driving from [XXX] back to my home state of [XXX] , I experienced an engine malfunction in Chester, Va where the 6.2 L87 engine was shaking and had severe hesitation. It was diagnosed by the Chevrolet dealership in Chester, VA as suffering severe failure of ALL 8 fuel injectors, fuel rails and connector harnesses, resulting in a 15 day repair wait and a $4,644.50 bill not including other expenses such as lodging/car rental. At this time my vehicle had 52,182 miles. After this I attempted for 3 months for GM to cover the repair as the vehicle was less than 5 years old and less than 60,000 miles under the 5 yr/60K warranty but denied it. On March 26th, 2026 while driving on the parkway at about 60 mph, my vehicle experienced loss of power (slow deceleration, shaking/hesitation) and I immediately took it to the repair shop where it was diagnosed as a P0308 code (misfire on cylinder 8) which caused a repair of the #8 spark plug, ignition coil and wire resulting in a $380. repair. Two days later, I experienced the same issue and then took it to an engine diagnostic specialty shop where I have been told that this issue will run about $4,000 due to valve and comprehension issues on an engine that has 60, 680 miles. I have seen numerous L87 engine complaints on Chevy Forums with no assurances that repairs or engine replacement will rectify the issue and feel that this is an issue that GM should be addressing for safety issues and an economic loss to its customers. I am hoping that your investigators can help the many people that have been left stranded by this incompetence and lack of admission of GM's part. Repair invoices available upon request.

I have had the vehicle in Auto and 2wd and it continues to happen. I can disengage the 2wd to auto and vice versa and it sometimes feels to help the problem.

  Lifter failed on my Chevy Tahoe 6.2L engine at ~75K miles in September 2025. One lifter bank was replaced. No reason for lifter failure was given. Less than 5 months later the other lifter bank has failed and damaged the cam shaft. Again, no reason for failure was provided. Failed lifters can cause catastrophic engine failure, which is incredibly dangerous when the vehicle is in motion. No check engine lights or and warnings occur with the lifter failure, it is only identified by the driver through the tapping noise from the engine. Even a cursory review of forums and complaints reveals that lifter failure is widespread on this engine and that manufacturing defects have caused issues with this power train dating back to 2019, not just the recalled 2021-2024 models.
