NHTSA — Structure: Body: Door Problems

CarComplaints.com Seal Of Pretty Good

CarComplaints.com Notes: The 2006 Buick Rainier has a lot going for it and just a few issues that keep it from making our "best vehicles" list.

The good news is the SUV has a quiet interior (thanks to triple door seals, acoustic laminate glass, and thicker sound-absorbing pads), a low number of overall complaints, and a RWD system which offers good balance and handling.

Unfortunately, it received poor safety ratings in crash tests, owners report that the gas gauge is unreliable, and there was a large recall for melting power window switches.

So close, Buick. So close.

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 this door and so it is still able to open for now from the inside until it locks its self again. Once it locks it's self again I won't be able to get the door open again to unlock the child safety lock cause the door no longer opens from the outside. At this point I have one door left that functions properly and that is the drivers door if that handle breaks I won't be able to open any of my doors from the outside and will only be able to open the two front doors from the inside. Who makes plastic door handles anyway what a stupid design for a car part that is used many times throughout the course of one day let alone for the life of the vehicle. I don't know if it is a safety issue but my daughter can't get in or out of the back passenger doors and has to crawl up through to the front seats and get out through the drivers door. I can't believe I have a fairly new car and can't properly use 3 doors on it. I too have issues with my gas gauge and will be taking it in to have fixed very soon.
