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.
