2020 Chevrolet Tahoe Problems

Transmission valve , vehicle shutter, and eventually complete loss of power and failure. Transmission had to be replaced as vehicle was out of warranty.

The dealership where I get my 2020 Chevy Tahoe service, stated that there is a recall for the water pump for the 2020 Chevy Tahoe, due to a manufactory defect, causing the water pump to leak. On XXX, mileage 62,777, I had to replace my water pump for that same reason, but my vehicle was not part of the recall; therefore, paying for a placement water pump myself. The dealership is Musson Patout Automotive Group/GMC, 214 West Hwy 90 Frontage Road, New Iberia, LA 70560, [XXX]. I am requesting that my vehicle be added to the recall list, due to this oversite. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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."

Suddenly lost all power steering, then warning power steering attention, no control for steering, very dangerous, couldn't drive vehicle. Took independent car repair to fix. $5k repair to fix problem. Should not happen to vehicle.

On multiple occasions, my car has locked my keys on the INSIDE of the vehicle. I have put things inside my vehicle before leaving and closed all the doors, upon returning, even just a few minutes later, my doors are locked and I am locked out of my vehicle. Additionally, my car is not detecting my remote. I cannot unlock my car with the buttons on the door and need to have my keys in hand for my car to detect the fob. Additionally, if someone opens the door while the car is running but in park, and then closes the door, the Car will beep as if there is no longer a remote detected. This has happened on multiple occasions. I have changed the batteries in the fobs multiple times, switched out my fobs so I was using a different fob and it has happened with both of my fobs.

Tahoe transmission failed with 103,000 miles… took to Chevrolet they confirmed, took to a transmission specialist they confirmed failure but they said the computer was throwing weird codes and they believe this has a factor in transmission issue. On the way home the brake system alert went off and the car would not go above 35 miles an hour … I get this is a safety feature but it was dangerous in the location this occurred ans this car was not that old and does not have high miles to justify this type of issues

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.

Creaking and groaning from rack and pinion. 60,000 miles on vehicle. no other issues. Potential steering system failure. No warning lights. Happens at all speeds.

The contact's brother owned a 2020 Chevrolet Tahoe. The contact stated that while his brother was driving at an undisclosed speed, the vehicle crashed; however, the contact was unsure what the vehicle had crashed into. The contact stated that the crash was a single vehicle crash and there was severe damage to the front of the vehicle. The contact stated that the air bags should have deployed but failed to deploy. The contact stated that medical attention was needed, and his brother was currently in the Trauma ICU after recently having back surgery.

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.

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.

Check engine light illuminated then went off and came back on after another drive cycle. Vehicle began to idle rough and experienced hard shifting and acceleration hesitation. I checked the oil and noticed a fuel odor smell on the dip stick and the oil appeared thin. Upon mechanic inspection they found a malfunctioning high pressure fuel pump. This part was recalled on other vehicles of the same model year due to bad welds. This could have resulted in fire if left unchecked.

Brand new set of tires. Less than 100 miles on them. During a left turn at roughly 15-25 mph the entire tire separated from the rim on the rear passenger wheel. The tire is in a secure location and can be inspected if needed. This led to an accident. There were no warning indicators such as low pressure indicators. The low pressure indicator came on after the tire came off the rim. The car went from make a 90 degree turn to making a 45 degree turn and cause my SUV to smash into a house. Tire size was 285/45/R22.

The contact owns a 2020 Chevrolet Tahoe equipped with Michelin Tires, Tire Line: M Plus S, Tire Size: P265/65/R18, DOT Number: M3KA007X0820. The contact stated that the rear passenger’s side tire was continuously losing air. While the vehicle was in for routine service, the tire was examined by the mechanic who discovered the cause of the failure was due to multiple pin holes in the tire. The contact was informed that the tire was unrepairable and needed to be replaced. The manufacturer and local dealer were notified of the failure. The failure mileage was 15,000.

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.

My car seat has failed the safety test on recall and they refuse to warranty it. It loosens significantly when pulled.
