Headlights go from bright to dim 4-7 times/minute when driving. Dealer replaced alternator, did not help. This will happen on some occasions only. *nm

Regarding exterior lighting- while driving at night -the headlights will suddenly go off & stay off for a period of time.sometimes they will come back on & stay & other times just stay off. It was not happening every time,but now seems to do it more frequently. I'm afraid to drive it at night.

When driving at night in the middle of a drive the headlights and drl failed. The next day they worked. This is similar to NHTSA id# 10724629. Called Buick at (800) 521-7300 and she said my complaint was recorded as service request 8-1699743903. She also informed me that even though some 2006 Buick rainers were recalled that my VIN was not included in the recall. I am experiencing the exact problem of other rainers and should be included in the recall. I informed Buick of this. Please contact bucik to demand the same.

Filled up at the gas station one day. Started my rainier and the gas gauge read empty and the low fuel light was on. Drove for a bit and the gas gauge appeared to start working again. Over the next couple of weeks the gauge would fluctuate randomly. Then one day, with my children in the car and my gas gauge telling me I had plenty of fuel, I ran out of gas on a very busy street. I was fortunate enough to coast into a parking lot and avoid an accident. My dealer kept telling me I needed to put a fuel cleaner into my gas tank and that would fix the problem. This faulty fuel sensor has caused me to run out of gas a number of times (even when using the trip mileage indicator to give myself some idea of my fuel levels). This creates a very dangerous situation. Please, please please iss

Filled fuel tank and gas gauge went to empty, turning on the low fuel light and the check engine light. The fuel gauge indicator bounces from empty to full. After a few miles the fuel gauge needle stays in range but as I get closer to needing gas it does not read accurately and I cannot tell for sure if I might run out of gas. My concern is running out of gas when in heavy traffic, fearing for my safety and that of any passengers. I believe this is indicative of a design flaw and needs to be adequately addressed by gm. I have a recall that indicates they would pay half the cost at a gm dealership, this is unacceptable to me. I am not half responsible for this design flaw. This is a serious safety issue and should be completely addressed by gm. *kb

Fuel gauge works erratically. When the gas tank is filled completely the fuel gauge reads low and dings the "low fuel" alarm. Gauge then climbs toward full as you speed up and then repeatedly drops to the low fuel alarm. The faulty fuel level could leave you stranded on the highway with no gas if you are not tracking your fuel level. *tt

Fuel gauge stopped working. Gauge became erratic reporting low/no fuel when tank was filled. Fuel gauge continuously bounces between full and empty. Behavior continues to exist. Can't rely on fuel gauge to determine when a fill up is required. Currently calculating mileage to next fill up by tracking mileage. Flashing low fuel light is distracting. *tr

The engine quits unannounced and the safety lock dash light illuminates. This can occur anytime regardless of speed. If at highway speed, the car will restart on itself. At low speed, I have to put the tranny in neutral and restart the engine. The dealer cannot find the source of the problem but suspects the ignition switch. The problem is what is causing this issue? *tr

12/15/2015 53,000 mi ODI #10810540.0

After filling up the vehicle with fuel, the gas gage goes to zero and the tank empty warning light comes on, after driving about 2 to 3 miles, the check engine light comes on. After driving another 10-15 miles the gas gage returns to showing actual level and the check engine light goes out. However, at about a tank level of about 1/4 the tank is near empty. This erratic malfunction of the gas gage is dangerous.

Buick rainier 2006: windshield wipers and fluid come on by themselves. When this occurs, the on / off function does not work. They cannot be shut off by controls. They merely start and stop at random. It happens both on vehicle start up when vehicle is in park and while driving. It is very difficult to see to drive.

I bought my 2006 Buick rainier in march of 2011 and about 3 months later the right rear passenger door handle broke because it is plastic and can't be opened from the outside. Then a week later the child lock decided to lock itself on the same door and now the door can't be opened from either the inside or outside. Then about 6 months later the front passenger door handle broke and now it won't open from the outside and I have to reach clear across the truck to open the door for any passengers to get in on that side. This last weekend the left back passenger door is now broke and can't be opened from the outside and is self locking the child safety lock now on this door as it did on the other back passenger door. Luckily I got the door opened just once to unlock the child safety lock on t
