Car Will Not Start problems of the 2007 Chevrolet Tahoe

While driving with cruise control enabled traveling at 70 mph with rpm at 2000 rpm, the 2007 Tahoe surged, jerked if you will, as if the cruise control was telling the vehicle it was going too slow. Hitting the brakes did not disengaged cruise control. Engine raced to 4000 rpm and locked at 4000 rpm! successfully shifted vehicle to neutral and was able to maneuver vehicle off the road and I can only hope the next person this happens to will be as lucky. Had to turn vehicle off to reduce engine rpm from the 4000 rpm it was locked on. Called on star and informed them of what happened and they ran a test which indicated no problem. Vehicle would not restart on first four attempts. Disabled cruise control button on steering wheel, which was glowing yellow, and the engine started. Gm customer service contacted, file 71-965035291 and gm refused to replace cruise control as the local dealer in san angelo TX indicated they could not duplicate the concern. If should be noted it was 104 degrees and the engine had been running for over an hour and 100 miles with the vehicle loaded with 5 people and luggage. The local dealer did not duplicate the exact conditions and instead did a test drive of 60 miles without the load or high temperature. Talked to sarah at 866 790 8601 ext 12869 and she passed me on to victoria, david, and then back to victoria. I am an equipment engineer and victoria did not appear to have any technical knowledge. Gm did not take my offer to remove my cruise control so they could bench test the unit and add heat to drive the faulty component to fail. Gm, specifically victoria, wants to wait until someone else has the same problem. I know this lack of action by chevy/gm seems hard to believe but the description I have provided is accurate.

The cluster readings turned off for a period of time while the vehicle was being driven and not able to see any speed nor gauges readouts during a period of over hour, stopped for gas and the vehicle did not started for 10 mins all cluster gauges not reading at all but able to turn the lights/radio etc.

Early last week, I took my wife's vehicle to a local tire dealer close to my home to have four new tires put on. One of the tire pressure sensors was bad so I went & bought a new one so it could be replaced. While switch was on (engine not running), the tire man began to re-train the sensors. In the process of all this & being indoors & the head lights were on (again engine not running) the battery ran down & the vehicle would not start. He had to use a jump box to start the car. During the running of the engine every idiot light came on & started one at a time to go out. After I left I found that the only thing that was changed was the engine hours re-set to zero. I looked on-line & found that there are several blogs concerning the same as I have described above with the same result. So I contacted gm via email on their web site to tell them the above. They called me back & claimed they never heard of such. They suggested I talk to my local Chevrolet dealer & find out what needed to be done. I explained all the above to edwards Chevrolet in birmingham, al. The service manager ask if anything else was going on besides the engine hours? I told him no. He said I should not worry about it. The next day the gm man called me back & I told him what the service manager said & he said ok but I probably need an electronic control module (ecm) & I said I ain't buying nothing as nothing else was going on with the car. Now I have gotten several calls from a woman at gm saying she has talked to the service manager at edwards and he told her the problem did not happen at edwards (even after I told gm that edwards had nothing to do with this) & happened at a independent dealer (which I already stated) & now the gm woman says I need to purchase a new instrument cluster. Here's what I see, this is a gm issue, not the Chevrolet dealer or the independent tire dealer. I have said all I am going to gm about this matter & I hold them responsible for this. Maybe now a Ford???????.

The contact owns a 2007 Chevrolet Tahoe. The contact stated that the vehicle failed to start. The contact mentioned that the battery was replaced on six occasions, but the failure recurred. In addition, the door locks independently locked and the lights on the instrument panel flashed intermittently. The vehicle was taken to the dealer where the negative cable hot 1. 5 ample and two volt drop positive cables were replaced, but the failure recurred. The manufacturer was notified of the failure.
