Gas-cap issues, front brake rotor wear and power-steering hose leaks are some of the common Buick Rendezvous problems. Most car owners report issues such as engine problems, interior-accessory problems and cooling-system problems.
Some Buick Rendezvous' develop coolant and engine oil leaking problems. Internal coolant leaks may occur causing a mix of the engine oil with the coolant. If the engine runs with a mixed coolant and oil, it may result to engine damage. Mechanics address the problem by replacing the manifold gasket.
Some Buick Rendezvous owners report having experienced problems when starting their vehicles. The problem may result from a faulty flywheel, diagnosed by the lighting of the check engine indicator. Consequently, the vehicle produces a peculiar sound when idling. Ultimately, the car fails to start, even when the battery has sufficient charge. The possible causes of the problem are a torque converter clutch failure or a clutch stuck in the wrong position.
The front brake rotor in a Buick Rendezvous may wear and lead to pulsation problems in the brake pedal. Mechanics correct the problem by replacing the brake pads and the front rotors. Some drivers report an illumination of the check-engine light. This occurs if the gas cap is loose or worn out.
