Tahoe 8-cyl

  • 40,000 miles
Actuator failed on 3 out of five doors, so far. Several forums have a lot of reports of failure. I would appreciate someone looking into this. Today, I am paying out of pocket over $500 to have this fixed at a Chevy dealership. You can never be sure a dock is locked or unlock, which poses a safety risk for my child who could open the door while I am going down the road; not to mention the risk of someone entering the car while it is stopped (attended or not).

  • miles
The battery gauge will drop or fluctuate. It does not occur immediately, but after driving for a couple minutes. Once the battery gauge drops many things are affected. The car hesitates to increase speed, braking is affected, cruise control is affected. The cruise control will turn on unexpectedly at times. When needing to accelerate it hesitates and once it goes the engine puts out more than is needed or expected. Braking is slow and pulsates slightly as the transmission is downshifting. The battery and alternator have been checked and appear to be in working order and nothing wrong with either of them.

The contact owns a 2009 Chevrolet Tahoe. The contact stated that the vehicle experienced a failure in which it would intermittently resist acceleration accompanied by a warning chime sounding. The contact also stated that the door locks would unexpectedly lock and unlock. The failure occurred regardless of the speed traveled. The vehicle was taken to an authorized dealer and they were unable to diagnose the failure. The vehicle was not repaired. The manufacturer was made aware of the failure and offered no assistance. The failure mileage was 57,000. Updated 07/06/12 on four occasions the door began locking, unlocking, chiming as if the doors were open. The warning lights began flashing and the vehicle would decelerate quickly as if the vehicle was placed in neutral and the accelerator was unresponsive. The dealer was unable to diagnose the problem.

Tahoe 8-cyl

I have an 2009 Chevrolet Tahoe ltz that has several electrical issues. My local Chevy dealer (lakeside Chevrolet in warsaw) hooked it up on their computer system and can't find anything wrong, so the dealer where I purchased this used vehicle (theautopark.net) replaced the ignition switch because they "think" that may be what's causing my vehicle issues. Below are the various issues that I am experiencing: 1. periodically, the door locks will cycle up and down and the power on the dash (radio, headlights, etc) goes black and the vehicle sputters like it's going to die (even while driving down the highway) 2. after that happens, and the vehicle comes out of this state, but if you smash down on the pedal the whole thing will occur again (huge safety issue while on the highway...no headlights and decreasing speed) 3. sometimes, the vehicle won't start (nothing happens) 4. the cd player sounds like the motor inside is constantly running. The dealer (theautopark.net) said this is a cooling fan...but it always runs? 5. the vehicle will completely die when placing the car in park and shutting off the engine (no power....nothing. Coasts to a halt.) note: We've already replaced the battery and still have all of the aforementioned issues. Update: The ignition switch replacement was a huge fail. On the way home last night, the vehicle did some really wacky things when I used my turn signal (the vehicle slowed dramatically while driving down the highway and the headlights and dash lights flickered off and on). All of this has made me angry enough that I disconnected the battery overnight to reboot the computer....I don't know if this helped or worked, but I am desperate enough to try anything right now because my family's safety is in jeopardy.

  • 4,810 miles
2009 Chevrolet Tahoe - with 5,194 miles intermittent and complete failure of all gauges on instrument panel and also intermittent cycling of door locks and horn as if the vehicle were being locked by using the remote. The failure of the gauges has occurred twice in the last 200 or so miles and the door lock cycling has happened once during the same period of time. There is no apparent pattern to the described problem. Since there are no gauges when the problem occurs, the drivability of the vehicle is severely limited; the speedometer, tachometer, oil, temperature and transmission gear selection indicator are inoperative. The vehicle is scheduled to be inspected on 02/10/2010 by the dealership where the vehicle was purchased and a replacement vehicle is being provided while the vehicle is out of service.
