The 2006 Buick Rainier has 4 recalls, the most serious being a fire risk tied to the driver's door power window switch module, which can short-circuit and start a fire even while the vehicle is parked and unattended.
Fluid can work its way into the driver's door master window switch module, corroding the circuit board inside. That corrosion can cause a short that generates enough heat to start a fire without any warning, and prior repair attempts using a protective coating on the circuit board did not fully resolve the problem, which is why multiple recall campaigns address the same underlying issue. The switch faults can also cause power windows to raise or lower on their own without any input from the driver. The fourth recall covers the headlights: on certain vehicles, the headlamps can fail to illuminate, reducing how much of the road the driver can see ahead and making the vehicle harder for oncoming traffic to spot.
