Owner-Reported Issues (20 of 386)

Power Train5 issues
criticalPOWER TRAIN
Filed: Mar 2026

While driving on the highway, your transmission suddenly lost power and wouldn't go faster than 30 mph, creating a dangerous situation with traffic behind you. When you stopped and restarted the car, it wouldn't engage reverse gear. Your vehicle isn't showing any warning lights or error codes, but based on online research, this may indicate a transmission or valve body issue. The fix will likely require a transmission inspection or possible valve body repair or replacement.

NHTSA #: 11723103
criticalPOWER TRAIN
Filed: Mar 2026

While driving your 2021 Chevrolet Tahoe, you pressed the accelerator but the vehicle didn't respond and lost power, then the transmission suddenly shifted into gear with a hard jolt that felt like being rear-ended. No warning lights appeared on your dashboard. The dealer diagnosed a transmission valve body failure and determined the entire transmission needs to be replaced. The fix will require replacing the transmission assembly.

NHTSA #: 11721469
criticalPOWER TRAIN
Filed: Feb 2026

While driving your 2021 Chevrolet Tahoe at highway speed (about 60 mph), the transmission suddenly failed without warning, causing the vehicle to lose power and slow down rapidly in traffic. This created a dangerous situation where vehicles behind you had to brake hard to avoid hitting you. The dealership diagnosed the problem as a transmission valve body failure and recommends replacing the entire valve body, which costs around $5,000 and may take over 2 weeks to complete due to parts availability.

NHTSA #: 11721164
highPOWER TRAIN
Filed: Mar 2026

While driving at 55 mph, your engine RPMs suddenly revved up and your transmission seemed stuck in 2nd or 3rd gear instead of the normal higher gear. Warning lights appeared on your dashboard saying "rapid deceleration use caution" and your check engine light turned on. When you tried to shift back into Drive after putting it in Park, the transmission wouldn't shift properly and your engine continued running at high RPMs in a lower gear. The transmission may need to be scanned for fault codes, serviced, or potentially repaired or replaced.

NHTSA #: 11721408
highPOWER TRAIN
Filed: Mar 2026

Your transmission started shifting hard and erratically while driving, and you received a propulsion warning message on the dashboard along with a check engine light. The vehicle wouldn't shift into reverse, so it had to be towed to the dealership. The dealer found the issue is in the transmission valve body, which is the component that controls fluid flow through the transmission.

NHTSA #: 11721561
Engine4 issues
criticalENGINE
Filed: Mar 2026

While driving 80 mph on the interstate, your Tahoe's engine revved to 4000 RPM with rhythmic vibrations, then shifted into Neutral and shut off completely. The dealership diagnosed this as a loss of propulsion requiring a full engine replacement. This happened at 104,000 miles.

Filed: Mar 2026

Your engine shut off unexpectedly while driving on the highway at 75 mph and wouldn't restart. After the dealership replaced the battery at significant cost without finding the root cause, your engine suffered a catastrophic internal failure (threw a rod) the next day at highway speed. This suggests the initial shutdown may have been a symptom of a deeper engine problem rather than a battery issue.

Filed: Feb 2026

Your 2021 Chevrolet Tahoe's engine suddenly seized while you were driving on the highway, causing a loud clunk and complete power loss. The engine won't crank or start, and the dealership confirmed this is part of a known recall issue affecting 5.3L V8 engines due to defective connecting rods or crankshaft problems — but your vehicle's VIN wasn't included in the recall despite having the same year, model, engine, and problem. The issue will require engine repair or replacement, which should be covered under the recall.

NHTSA #: 11720030
criticalENGINE
Filed: Feb 2026

While driving slowly to a stop sign, your engine suddenly made a loud clunking noise and the vehicle abruptly stopped without warning. Multiple dashboard warning lights came on immediately, and you heard knocking sounds coming from the engine. Your vehicle won't operate normally and the sudden failure created a safety risk, especially since you were driving at night with children in the car. The engine may need professional inspection to diagnose internal damage, which could require significant repairs or engine replacement.

NHTSA #: 11718169
Electrical System2 issues
criticalELECTRICAL SYSTEM
Filed: Mar 2026

Your vehicle lost communication with the OnStar system while driving, and you believed your brakes failed along with other safety systems becoming inoperable. The dealer was notified but didn't diagnose or repair the issue. This happened at 114,000 miles, and Chevrolet has been made aware of the problem.

NHTSA #: 11726696
highELECTRICAL SYSTEM
Filed: Mar 2026

Your truck's sound system cuts in and out intermittently, including the audio alert for your turn signal. Because you can't hear the blinker click, you have to look down at the dashboard to confirm the blinker is activated, which creates a distraction while driving. The issue likely involves a faulty electrical connection or module controlling the audio system and turn signal sounds.

NHTSA #: 11722367
Engine And Engine Cooling2 issues
criticalENGINE AND ENGINE COOLING
Filed: Mar 2026

Your engine is consuming oil much faster than normal, and you're hearing abnormal knocking sounds from the engine. You may also notice the engine hesitates during acceleration, blue smoke coming from the exhaust, and your check engine light turning on and off. A dealer inspection found metal shavings in your oil, which indicates internal engine damage that typically requires a complete engine replacement.

NHTSA #: 11723551
criticalENGINE AND ENGINE COOLING
Filed: Mar 2026

Your 2021 Tahoe's engine developed a knocking sound while driving, along with a check engine warning light. A mechanic discovered a bent engine rod, indicating engine failure at 72,000 miles. This issue is linked to a known manufacturer recall, and the manufacturer has agreed to cover half the cost of engine replacement. The repair will likely involve removing and replacing the entire engine.

NHTSA #: 11722487
Seat Belts1 issue
criticalSEAT BELTS
Filed: Mar 2026

Your third-row seat belts don't lock properly when you try to fasten them. This prevents the seat belts from securing occupants in those seats during driving or in a crash. The seat belt retractor mechanism or locking mechanism may need to be inspected and repaired by a technician.

NHTSA #: 11726587
Electrical System,engine,fuel/propulsion System1 issue
criticalELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM
Filed: Mar 2026

Your 2021 Tahoe is unexpectedly shifting into neutral, losing engine power, and stalling while driving — sometimes without warning — creating dangerous near-miss situations with other vehicles. This has happened multiple times since March 2025, and your dealer has replaced six different components based on error codes, but the problem keeps returning within days to two months. The dealership and Chevrolet Customer Care claim the vehicle is safe, but you've spent over $6,000 on repairs and don't feel confident driving it. Identifying and permanently fixing the underlying electrical or fuel system fault will likely require comprehensive diagnostic testing to find the root cause rather than replacing individual parts.

NHTSA #: 11724504
Steering,power Train,engine1 issue
criticalSTEERING,POWER TRAIN,ENGINE
Filed: Mar 2026

Your 2021 Tahoe has three serious issues: the engine is burning excessive oil (5 quarts every 3,000 miles), causing thick white smoke to pour from the exhaust unexpectedly—a frightening situation that caused panic among your passengers. The transmission jerks harshly when shifting gears, and the steering wheel has become unstable. A Chevrolet dealer determined the vehicle is unsafe to drive due to the transmission and engine problems. These issues will likely require engine rebuild or replacement, transmission repair or replacement, and steering system diagnosis.

NHTSA #: 11721272
Electrical System,engine,forward Collision Avoidance1 issue
highELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE
Filed: Mar 2026

Your truck started making knocking noises and acting rough while idling, then multiple warning lights appeared on your dashboard: the ESV service light, engine light, and forward collision avoidance system failure light. Your vehicle has lost significant power and you're noticing a burning electrical smell from under the hood. The truck is not drivable for normal use and needs immediate diagnosis to identify what's causing the electrical and engine issues.

NHTSA #: 11722698
Exterior Lighting1 issue
highEXTERIOR LIGHTING
Filed: Feb 2026

Your driver's side headlight adjuster broke on its own while driving, causing the headlight to point downward and severely limiting your nighttime visibility. The dealer says the entire headlight assembly must be replaced—a costly repair requiring bumper removal—but both the dealer and GM refused to cover any costs. You're concerned this is a design defect since the plastic adjuster arm separates inside the assembly with no way to access or repair it.

NHTSA #: 11720423
Fuel System, Gasoline1 issue
highFUEL SYSTEM, GASOLINE
Filed: Feb 2026

While driving at 25 mph, your Tahoe lost power when you pressed the accelerator and then stalled without warning. The dealer found that the fuel module had failed and replaced it. You discovered online that this failure matches a known recall campaign, but your vehicle's VIN wasn't included in that recall. The fuel module will need to be replaced to restore normal operation.

NHTSA #: 11719431
Power Train,vehicle Speed Control,engine1 issue
highPOWER TRAIN,VEHICLE SPEED CONTROL,ENGINE
Filed: Feb 2026

While driving your Tahoe at 35 MPH, you heard an abnormal clunking sound followed by unexpected engine revving, a check engine light, and a message telling you to reduce acceleration and drive with care. Your vehicle then started coasting on its own before returning to normal operation after a short time. The dealer diagnosed a transmission valve body failure that requires replacement.
