Two problems related to other fuel system pump have been reported for the 2004 Buick Rendezvous. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Buick Rendezvous based on all problems reported for the 2004 Rendezvous.
My vehicle has been picking up speed for no reason. The vehicle was not taken to nor taken to a dealer for diagnostic testing or repairs. Also, the fuel pump is not working. I can fill it up with gas and the light will still turn on. Maybe after driving for a couple miles or making a turn the light will turn off.
No acceleration,when I go up a hill no acceleration, or when I go to get on the highway no acceleration, and very dangerous. I went to dealership for a diagnostic test and I replaced fuel tank pressure sensor and vent solenoid, no acceleration. I went to another dealership for diagnostic. They recommended that I replace 3 electrical harnesses and connectors $1350 dollars parts and labor too much for me and that may not solve my problem. I told them the problem was corrosion in the connectors to the fuel pump $160 dollars later they agreed with me. Still dangerous.
