2025 Chevrolet Tahoe Problems

What owners report

Owners of 2025 Chevrolet Tahoe models most often report sudden internal engine failures, followed by power loss, misfires and shutdowns while driving. Brake and ABS warnings and driver-assist braking complaints form smaller groups. The model year is new, so the reports cover a short period, and most do not state mileage.

   Internal engine failures (thrust and rod bearings)

   • 24 complaints (46%)
   • typically at 1.6 yrs old
   • 1 mention a crash, fire or injury
   • filed 2025–2026

   Owners describe sudden internal engine failures, most often involving thrust bearing or crankshaft play, and in some complaints rod bearings, lifters or camshaft parts. Some describe losing power or shutting down while towing, at highway speed or on a grade, and some say there were no warning lights before the failure. Dealers reportedly confirmed internal failure and recommended complete engine replacement. Some complaints mention a GM bulletin on thrust bearing failure or the 6.2-liter L87 engine, and a complaint says warranty coverage after the repair would be limited to the remaining powertrain miles. Where mileage appears in the complaint text, these reports range from about 3,400 to 65,000 miles, and some describe the failure at highway speed or while towing.

   What to check: Ask whether the dealer has checked for the thrust bearing bulletin mentioned in complaints, and request the engine and oil change records. Listen for knocking or rumbling at idle and under load during a test drive, and ask for an oil pressure reading before purchase.

   “2025 Chevrolet Tahoe, 6.2L L87, approximately 51,500 miles, rod-bearing/internal engine failure, complete engine replacement required. 1500 miles prior to engine failure the cam/lifters were replaced. Repair invoices are attached. I was told my warranty going forward would be the remaining miles left on my 60k power train warranty. This is not acceptable.”

   NHTSA complaint #11760708, filed 2026-08

   “Dealer grounded vehicle for excessive crankshaft play due to thrust bearing failure. Been without vehicle since 1-20-2026 and although I have received 2 text from service manager I have not been told when I will get vehicle back. Mileage was at 4,820. Vehicle build date 7/25”

   Power loss, misfires and shutdowns

   • 25 complaints (48%)
   • typically at 1.5 yrs old
   • 1 mention a crash, fire or injury
   • filed 2025–2026

   Owners describe losing power, lurching, or shutting down while driving, often with warning messages such as reduced power mode or a check engine light. Some say the car would not restart after it shut off, and some were towed, including a case where the car could not be put in neutral or out of park. Some describe misfires or rough running, including a misfire that persisted after coil packs and spark plugs were replaced, and a misfire that recurred after oil changes. Some complaints say dealer diagnosis took weeks and that no loaner vehicle was provided. Where mileage is given, reports range from about 3,400 to 19,000 miles, and most describe the problem happening while the vehicle was being driven.

   What to check: Ask for the full diagnostic history and any warranty repair records for misfires or power loss, including any stored codes. Test drive at highway speed and watch for hesitation, warning messages or loss of power, and check that the car shifts normally out of park.

   “I was leaving my neighborhood on Saturday night 5/16 around 5:30 and on the way out all of a sudden the dashboard started lighting up and the speed was dropping despite me being on the gas. The screens kept flashing then the car stopped and went into park and I could not get it out of park. I was at the front of my nieghborhood entrance and it made it hard for others to come in and out. I tried to restart it. My husband tried to jump it. …”

   NHTSA complaint #11738644, filed 2026-05

   “While I was driving, my vehicle suddenly lost all power I encountered a misfire with the engine light flashing, and diagnostic codes P0353 and P0300 indicated a misfire on cylinder three. The coil pack and spark plugs for that cylinder were replaced, yet issues persist and problems continue. There is a strange popping and cracking noise coming from my dash. My brakes are also making it loud sound randomly when pressing on breaks yet brake pads are fine”

   Brakes

   Brake failure, ABS and brake assist warnings

   • 10 complaints (19%)
   • typically at 1.1 yrs old
   • filed 2025–2026

   Owners describe brakes that suddenly lost effectiveness, with the pedal going to the floor or needing very hard pressure to slow the vehicle. Many of these complaints list dashboard warnings at the same time, such as brake assist failure, ABS or ESC errors, trailer brake errors, or speed limits. Some describe the emergency brake as the only means of stopping, and a complaint says the parking brake can only be applied when the vehicle is fully stopped. A complaint describes repeated wheel speed sensor and braking module repairs, with traction control and ABS warnings returning. Where mileage appears in the text, reports cite about 24,450 miles, and where speed is stated, the failures happened at 40 to 70 mph.

   What to check: Ask whether the dealer has scanned for stored ABS, brake assist and ESC codes, and whether any brake module or wheel speed sensor repairs were done. During a test drive, check the brake pedal feel and warning messages, and confirm the parking brake applies and releases normally.

   “Brake system failure. Brakes were all but gone as I couldn't safely stop my car at an intersection and had to quickly cut in front of on coming traffic to go into a gas station to avoid running a red light.”

   NHTSA complaint #11691515, filed 2025-10

   “I am filing a safety complaint regarding my 2025 Chevrolet Tahoe Premier for repeated brake assist/braking failures. Most recent incident: While driving, the check engine light came on. I turned the vehicle off for approximately 10 minutes and restarted it, but the check engine light remained on. Approximately 20 minutes later, multiple warnings appeared on the dash including: “Brake Assist Failure Press Hard to Brake,” “Speed Limited,” and “Service ESC.” At that point, braking ability was severely reduced. …”

   Forward collision avoidance

   Automatic braking and lane assist acting unexpectedly

   • 8 complaints (15%)
   • typically at 1.5 yrs old
   • 2 mention a crash, fire or injury
   • filed 2025–2026

   Owners describe automatic braking that engages without an apparent reason, including in slow traffic, while reversing with nothing in the way, and when a person is nearby but not in the path. A complaint links the reversing stops to shadows, and says rain worsened it when water sat on the camera lens. Another complaint says the automatic braking slammed on at low speed in traffic and was followed by a rear-end collision. A separate complaint describes Super Cruise signaling a lane change toward a vehicle beside the car, which the driver prevented by taking the steering wheel. Where mileage is given, it is about 8,500 miles, and the braking events were described during slow traffic, reversing and parking.

   What to check: Test the automatic braking features on a safe, open road and in a parking area, including in rain, to see whether they engage without a reason. Ask whether the dealer has checked the camera and whether any driver-assistance software updates have been applied.

   “When backing up the auto braking brakes very hard sudden stop without warning even though no objects near by. Appears to be from shadows and made worse when it is raining and the camera has water on the lense. I turned off the backup auto braking and it still does it. It brakes hard enough that it pinched a nerve in my neck causing sudden pain which chipped a tooth”

   NHTSA complaint #11696183, filed 2025-10

   “I have a 2025 Chevy Tahoe and the automatic braking system is way too sensitive. When I’m reversing, it constantly slams on the brakes even when I still have enough space and nothing is in my way. It also brakes when people are nearby but not actually in my path. One time I was stopped and about to move forward, and the car suddenly braked because a construction worker was a few feet away, not in front of me. It caught me off guard and didn’t feel safe. …”

Buying note. Buyers considering a 2025 Chevrolet Tahoe should ask for the engine and oil change records, check recall status by VIN including the front wheel hub recall, and ask whether any thrust bearing repair has been done. Test drive the vehicle at highway speed and check brake pedal feel, warning lights and automatic braking behavior, since these are the areas where complaints cluster.
