Failure Date: 04/28/2014

The Buick Rendezvous would not start after our son little practice had to tow out of park. Electrical ignition switch had to be replaced by local mechanic. Also out of every 10 starts 2 or 3 have a hard time starting and when you drive on road and push gas pedal it seems like it will stall completely I went to Buick dealer but he told me there is no reacall on this car. I am afraid it will stall on road my kids are in this car all the time I am afraid for them the dealer said he would take a look but I would have to pay to fix because this is not part of recall I think this is horrible treatment of regular people taking money and more money and not concerned about safety what country is this. Usa or some 3rd world country all I want is gm to fix relay between key and ignition switch and change computer module under hood and give me new key I have always bought gm but them and their dealers are making pray everyday that nothing happens to my family in their car.

Summary: on certain sport utility vehicles, contamination on ignition relay contacts can cause high resistance. This can affect signals to the powertrain control module and, could cause intermittent vehicle stalls at any time. Consequence: the vehicle cannot be restarted immediately. If this were to occur, it could result in a vehicle crash.

1. 2004 Buick Rendezvous stalls driving at all speeds. Will not restart until it sits awhile. 2. Starter stays engaged and whines after engine starts for aprox. 3 to 4 seconds. 3. The gas tank is leaking around the filler neck where the tank is (welded). All of these problems have been looked at by 2 dealerships and I have contacted gm to get these problems, all of which are recall problems fixed. Gm will not repair my vehicle after one of the dealership service departments stated that my vehicle was considered undriveable and a serious vehicle hazard. Gm stated that since my vehicle was a part made by a different manufacturer the exact problems on the recall would not apply. Repair cost estimate was aprox. $1200. Gas leak is about 8 inches away from the left rear "hot" brake rotor "fire". Ea07-006. Pco.

The vehicle experienced total electrical failure and would not start. The car radio, door locks, and instrument panel would repeatedly light up and turn off even with the key out of the ignition. The body control module had to be replaced. Buick refused to honor the warranty on this part. As a result, I paid $575 for the repair.

Failure Date: 05/02/2005

The contact stated vehicle stalled while driving. The only warning was the battery light. When the vehicle stalled there was no steering or brakes. The vehicle was taken to the dealership, and they have placed a recorder on the vehicle three times. From the information obtained from the recorder they have replaced the ignition relay, ignition switch, the air control module valve, and reprogrammed the computer. None of these repairs have corrected the stalling problem.

The vehicle stalled when driving on the highway. The vehicle would sometimes cut completely off. The vehicle was taken to the dealer for service, but the dealer could not duplicate the problem. While the dealer was trying to find the problem with the stalling, they found that the brake module lost communication with the computer. The stalling problem continued to occur. Other problems were: the battery light had come on followed by engine stalling, the ebcm was intermittently dropping out therefore the ignition relay was replaced and the liftgate did not open properly.
