2024 Chevrolet Tahoe Transmission Problems

Your 2024 Tahoe stalled without warning while driving at 55-60 mph, and later shifted unexpectedly into neutral and entered a reduced-power "limp mode." The dealer found multiple trouble codes related to the engine control module, transmission solenoid, and communication issues, but was unable to repair the problem after 10 visits. Chevrolet has opened a case to investigate what appears to be a serious electrical or transmission control system malfunction that may require replacement of the transmission control module, engine control module, or related wiring harnesses.

Your vehicle passed a diagnostic test in February 2026, but later you received an oil pressure warning light while driving and the engine shut down in the middle of the road. The dealer determined the engine had failed and needs to be replaced. The repair will involve removing and installing a new or rebuilt engine.

Your transmission shifter has repeatedly failed, preventing your Tahoe from going into reverse even though you can shift into drive. Each time you take it to the dealer, they replace the shifter, but the problem keeps coming back after a few hundred miles. The dealer has confirmed the shifter itself is the culprit and replaced it four times already.

My wife drove the 2024 Tahoe with 13,464 miles to Florida for a beach trip with the kids. The car stopped working while she was driving. The vehicle flashed and the automatic transmission wasn’t changing gears. She manually shifted the gears until arriving at a safe place. The dealer states it is the transmission valve body that needs replaced. The part is on back order and from what the dealer said being built as needed.

Brand new 2024 Z71 Tahoe at 11,000 miles had transmission failure due to the transmission valve body failing. No previous issues, has never driven long distance, has never towed anything. While in school drop off line was alerted and given an error message on screen stating “reduced acceleration, drive with caution” placing the vehicle in limp mode and check engine light came on.

My family and I were returning from vacation from Florida to our home state, North Carolina, when our new Tahoe with 5700 miles started to act strangely. We hit bad traffic leaving Florida so there was plenty of stop and go type maneuvers. At one point, the vehicle turned itself off and put itself in neutral while we were thankfully going a slower speed due to traffic. I was able to get off the shoulder near the [XXX] and restart the car. It ran fine after restart until it started making a clanging type noise from the engine bay. We stopped again and checked temperatures and fluids and the clanging stopped. About 30 minutes later the clanging and a guttural noise began to occur from the engine bay and the transmission would not shift, keeping the vehicle at/around 4,000 RPM at 60mph. We were able to get the vehicle to a nearby rest stop. My wife, 3 children, and I were put in harm’s way due to GM’s faulty product and poor quality control. To have your vehicle shut itself off and/or not shift, especially on the interstate, is incredibly dangerous to the occupants of the vehicle as well as the motoring public. It is important to note that the vehicle never displayed any warning lights of any kind before, during, or after the incidents described. Almost two weeks later, Chevrolet (Cooper Chevrolet S.C.) has not even diagnosed the vehicle. They have told be that they will more than likely have to tear the motor apart to figure out the issue(s), confirming that the problem has been replicated by their technicians. The Tahoe is equipped with a 6.2l V8, a motor with well documented issues. The Tahoe is currently located at Cooper Chevrolet in Walterboro North Carolina.
