2023 Chevrolet Tahoe Problems

What owners report

Owners of the 2023 Chevrolet Tahoe most often write about engine failures, frequently describing a sudden loss of power or stalling at highway speed with little or no warning, in some cases before or after engine work tied to the 6.2L V8 connecting rod/crankshaft campaign. Transmission complaints follow, typically a valve body failure that leaves the vehicle in limp mode or shifting into neutral. Electrical complaints are reported at lower mileage and involve the infotainment screen, warning messages and driver-assistance systems dropping out.

   Engine

   Engine stalls or fails while driving (6.2L V8)

   • 110 complaints (47%)
   • median 32,295 mi at 2.5 yrs old (19 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2023–2026

   Complaints describe the engine shutting off at highway speed, with the vehicle dropping into neutral and losing power steering assist, sometimes preceded by a tapping, knocking or squealing noise. Several owners report being told by the dealer that the engine needs replacement, and that replacement engines were backordered with no repair date. Others mention that the failure happened before or shortly after work tied to the 6.2L engine campaign; a few describe a second engine failure after a replacement. Mostly reported between roughly 17,000 and 60,000 miles, sometimes at highway speeds without prior warning lights.

   Recall 25V2740006 related service bulletins

   What to check: Ask whether the 6.2L engine campaign (25V274000) inspection was completed and what result it returned, and whether the engine or any internal parts have already been replaced. Listen for tapping or knocking at start-up and during acceleration, and check the oil level and condition.

   “1 week and 1 day later we are stranded again on the side of highway going full speed in our Tahoe. We took it to two different certified Chevy dealerships and they gave us a vague resolution and this issusr is not fixed at all. Our engine is locking up on us at full speed on the highway. This vehicle has 83,000 miles on it and we’ve maintained this vehicle very well.”

   NHTSA complaint #11762588, filed 2026-09

   “I purchased a 2023 Chevrolet Tahoe on December 17, 2025. On January 17, 2026, with approximately 17,000 miles, the vehicle experienced a catastrophic engine failure while I was driving. The engine seized without warning, causing a complete loss of power and leaving me stranded on the side of the road. At the time of the incident, my newborn child was in the vehicle, creating a serious safety risk. The vehicle had no prior warning lights or indicators before the failure. …”

   Transmission and drivetrain

   Transmission valve body failure, limp mode, harsh shifting

   • 51 complaints (22%)
   • median 37,000 mi at 2.5 yrs old (8 state mileage, few)
   • filed 2023–2026

   Owners describe the transmission refusing to shift normally, downshifting on its own, shuddering at cruising speeds and at low-speed deceleration, and dropping into a reduced-acceleration or limp mode with the check engine light on. Dealers commonly diagnosed a failed transmission valve body, and owners note that the part was often on backorder. Some were told the vehicle was not safe to drive while waiting. Often reported between about 15,000 and 40,000 miles, during steady cruising or light acceleration.

   3 related service bulletins

   What to check: Test drive at steady 40-55 mph and during gentle deceleration, looking for shudder or vibration, and ask whether any transmission valve body work or fluid service has been done. A service bulletin describes checking the transmission cooler lines for twisting when harsh shift or shudder is reported.

   “The vehicle’s transmission began slipping at low speeds with less than 40000 miles. I took it to the dealership for diagnostic testing and the requested that I do “maintenance transmission fluid replacement” as well as some additional reprogramming which the dealer also deemed as maintenance. However, the required transmission fluid replacement was not required until 45000 miles and the reprogramming is not listed anywhere in the maintenance plan.”

   NHTSA complaint #11655979, filed 2025-04

   “We were driving on a busy interstate in Knoxville, TN on a Sunday. We were 2 hours from home and my 2023 Tahoe basically went into limp mode while I was in the fast lane and the check engine light came on. No warning in advance. The speed reduced, which backed traffic up, and put me and my 4 children in danger. We finally got off the interstate and the vehicle had to be towed in to the nearest dealership. I had a friend drive us to enterprise where they put us in a Jeep Grand Wagoneer. …”

   Electrical system

   Infotainment screen blanks and driver-assist systems drop

   • 78 complaints (33%)
   • median 33,253 mi at 2.7 yrs old (9 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2023–2026

   Complaints describe the infotainment screen going black and requiring the vehicle to be shut off and the key fob removed before it returns, then crashing again within a short time. Owners link this to loss of the warning chimes, backup camera, lane assist, forward collision alerts and OnStar function. Others report the instrument panel going blank, the backup camera activating in drive, or warnings such as "No Key Detected" and various service messages appearing; dealers often could not duplicate the faults. Reported across a wide mileage range, several under about 20,000 miles.

   Recall 22V9030006 related service bulletins

   What to check: With the vehicle running, check that the touchscreen stays on, that chimes and warning sounds work, and that the backup camera, lane assist and forward collision alerts behave normally. Ask whether any electrical module resets or reprogramming were performed.

   Engine cooling

   Excessive oil use and lifter or top-end noise

   • 21 complaints (9%)
   • median 30,626 mi at 2.9 yrs old (4 state mileage, few)
   • filed 2025–2026

   Complaints describe the vehicle calling for oil between services, an "Add Oil" message after dealer service, and tapping or ticking from the engine compartment that grew louder under acceleration. In some cases dealers replaced lifters or camshaft components; in others owners were told the noise was normal or that the vehicle could not be diagnosed until it failed. Reported from around 15,000 miles upward, often noticed between oil changes.

   3 related service bulletins

   What to check: Check the oil level and look for a fuel or burnt smell, and note whether oil changes were done more often than scheduled. Listen for ticking at cold start and ask whether any lifter, camshaft or coolant control valve repairs have been recorded.

   “Piston ring went bad causing catastrophic engine failure. Now needs new motor. Only had 62k miles. It had been burning oil but was taken to the dealership for maintenance and they didn’t report anything.”

   NHTSA complaint #11750556, filed 2026-07

   “The contact owns a 2023 Chevrolet Tahoe. The contact stated that after the vehicle was serviced at the local dealer, the message Add Oil was displayed, and the vehicle continued to experience excessive oil consumption. The cause of the failure was not yet determined. No further information was available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 18,000.”

   NHTSA complaint #11712054, filed 2026-01, 18,000 miles

Buying note. Because engine and transmission complaints dominate this model year, ask for the full service history and confirmation of whether the 6.2L engine campaign inspection and any transmission work were completed. A slow test drive at cruising and low speeds, plus a cold start listening check, will surface the shudder and engine noise owners most often describe.
