general problems of the 2009 Chevrolet Tahoe

I purchased the gm sts2 software and program my truck and now I have no brakes, have all lights on with calibration and rams problem I’m sure that the calibration they provided to me, costed this problem and none off the lights are turning off, the truck lost brakes I have to stand on the paddle to stop the truck. Now I have no choice to send it the gm for there mistake. I spoke to acdelco sts2 rep. And he couldn’t figure out the problem. And the hybrid system issue also. Both front air bag impact sensors cracks in the middle turns the light on. That’s been a fault with all gm trucks. They need to update this problem.

Takata recall has a recall on my vehicle airbags. When I hit a pothole on city street airbag came out, brakes locked up and stabilization and traction controlservice lights came on. Had to call for a tow truck. .

When driving the dash lights flash, door locks move up and down, speedometer will go to zero then back up to speed an so forth, the Tahoe will start gearing down on its own, the air will go off, and the radio will flash on and off. The vehicle has even shut completely off before when going down the interstate. Have had to replace dvd player,horn. Also have 3 children this vehicle is not safe at all to drive. I dont want to sale it because im scared for someone eles's life.

I have had to replace the brakes twice, as well as the driver side hub. I have replace the door trim at least 4 times. Everyone I have met that has the same year has had trouble with the trim. I also feel that the transmission has trouble shifting when towing.

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.

On or about 8-9-10, we felt a shuddering feeling in our vehicle. We took the vehicle to a gm dealer and they stated the brakes needed to have the rotors turned. Gm dealer completed repairs and on or about may of 2011, vehicle began to shudder again. We took the vehicle back to the same gm dealer and the rotors were bad again. The dealer stated that the rotors had been turned improperly back in August 2010. They returned the rotors and told us it was an engineering defect and that we would have to come back every year to have our brakes repaired and they would take responsibility. On or about 8-5-11, the vehicle began to shudder once again. On 8-9-11, we returned the vehicle to the same gm dealer and advised them it was shuddering again. The service representative advised that we would have to replace the rotors and it would cost us as it is not covered under warranty. We informed him of the prior visits and he was not forthright that he knew of our vehicle. I advised him that I was told by the service manager that the rotors were repaired improperly and he acknowledged it was a bad machine and they have a new one now. He said it was due to our driving habits and was not a warranty item as it is normal wear and tear. He then attempted to change the conversation by getting us to perform recommended maintenance on the transmission, fuel injectors, and differential. These services were not even required by the owners manual until at least 100,000 miles and this vehicle only has 30,000 miles currently. We changed the conversation back to the issue at hand (the brakes) and he said he would inspect and advise and document to the service manager.
