2005 Buick Rainier Reviews

I have had suspension problems, gas gauge problems and now thermostat problems. I have replaced the temperature sensor which caused temperature to jump all over the place. Started out stuck at 50 degrees, now climbs to 120 degrees. Problem is the air conditioner stops working when reading changes radically, up and down. I am a cardiac patient with asthma and emphysema and cannot ride in the extreme heat without a reliable source of cooling. When it works, it cools beautifully, but doesn't last. It is so sporadic, I can not rely on it. What can I do? Seems electronics are a big problem.

I have had this vehicle for 2 + yrs it had 101,592 miles on it when I first got stuck with it. Since then I had to have the valve cover gasket replaced ($378) (intake manifold also had to be replaced), at 103,692 miles the transmission failed, it had to be rebuilt ($3012.80)it was determined that when assembled by GM they assembled it was not aligned properly at factory, then the thermostst went out (cost $239), when thermostat went the gauge in instrument panel stoped working it had to be sent to location to be fixed. Since I've had this vehicle it has done nothing but fail. Iwill not buy or reommend a Buick to anyone!

I need a repair on the rear air springs, the air compressor has failed causing the rear suspension to sit low. I also need to get the front Differential rebuilt. Has anyone had any of these repairs done and at what cost???

I started having problems with my 2005 buick rainier shortly after purchasing the car. When you press the brakes sometimes the car will fish tail and have failed twice. The Buick dealership I purchased the car from fixed the issue and pretended it was never a problem because the insurance company called after I had an accident and the brakes failed. The other problems started after reaching 100,000 miles. It has been a complete mess that Buick seems to ignore. It started with the gas needle fluctuating. I fixed it last year. Buick recalled it this year. Next, the oil needle fluctuates, the check engine light is on majority of the time due to the fuel cap. The hvac blower got stuck on high, repaired that. Now the heat comes on by itself sometimes. Let's not forget the rear air springs issue. I will replace that next. Several of the controls went out but the fuse is not blown. Complete mess of a car.

Love the Ranier. Only problem is recent. The air conditioner and heater has intermittent blower issues.
