One problem related to instrument panel failure has been reported for the 2008 Chevrolet Tahoe. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2008 Chevrolet Tahoe based on all problems reported for the 2008 Tahoe.
While driving on the interstate all of the dash board instruments lost power, the door locks actuated as rapidly as possible, the four wheel drive engaged, and the engine temporarily lost power, & all the dome lights came on. The entire episode lasted aproximately five seconds outside of the four wheel drive would not go back into two wheel until the vehicle was shut off and the ignition turned on. This type of scenario has occurred now four times. At one point the vehicle locked itself while shut off with our two year old child in the car stuck in his car seat. The vehicle is going in tomorrow for the fourth time and the mechanics have not been able to replicate the problem. The most recent event was preceded by the rear door refusing to open prior to departure, the headlights flickering, the radio panel shutting off, and when the headlights were switched from dim to bright the door locks again actuated at a high rate, the entire instrument fell dead, the engine briefly lost power & the air bag lights went on and off for about twenty seconds. Once the major failure happened the radio and instrument panel would go dead about every five minutes. Once we reached our destination I shut the car off and went to start it the next day and it had simular problems.
