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.

Rainier 6-cyl Diesel

The fuel gauge suddenly showed empty after filling and then about 10 miles later showed full. Shortly later empty again. The erratic fuel readings continue to date. This malfunction is creating a very dangerous situation. Buick is not willing to repair or replace the fuel gauge.

This Tuesday as I was driving down a major highway with my 2 year old daughter, my 2006 Buick Rainier turned off and came to a complete stop. It was freezing cold and we were on a major highway, luckily I was able to coast to the shoulder and no one was hurt. Come to find out I ran out of gas. I have never in my life run out of gas, my fuel gauge was reading incorrectly. I had to make my husband leave work, while my daughter and I had to sit in the freezing cold car!!! I have an appointment to fix the fuel gauge, and I was informed this is a common problem. GM is only paying half the repair costs, although they admit this is a defect. Please help, these repairs are not in my budget, but I also can not be stranded again.

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 issue a recall as soon as possible.

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.

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.

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.

Rainier

  • 55,000 miles
The gas gauge began reading empty when it was actually full. This started in spring 2010 with the odometer reading about 65K. When the tank is initially filled the gauge will read full, then go down until the gauge read empty. This continued for several days after fill-up and fluctuated between full and empty. After driving approximately 15 to 20 miles the gauge would return to full and back to empty again. There needs to be a recall on this vehicle. I already paid my Buick dealer over $500 to correct this problem, which is not the result of wear and tear or carelessness or misuse on my part, but rather the failure of a critical safety device. The consumer should not be required to bear this financial burden.

Fuel level sender in the gas tank fails, gauge is unreliable and indicated full tank or empty tank randomly. Can indicate a full tank with only a little bit of fuel left.

Rainier 6-cyl

  • miles
Approximately 3 months ago after filling my tank and starting my 2006 Buick Rainier the gas gauge read past 'empty' and the 'low-fuel" warning light came on. This continued for several days after fill-up and fluctuated between full, empty and all points in between. In addition the check engine light comes on with each fill-up. After driving approximately 15 to 20 miles the gauge would return to more accurate readings. However, most recently this is no longer the case as the false gas gauge readings, low-fuel and check engine warnings have become constant and I can no longer trust them at all. This is a huge problem with a $500 + price tag which consumers should not have to bear.

The gas gauge began reading empty when it was actually full. This started on 03/03/2011 with the odometer reading about 70K. It now has about 76K on the odometer. When the tank is initially filled the gauge will read full, then go down gradually while driving until the gauge read empty. When the tank was full the service engine light would also light until the tank would be at approximately 3/4. at 3/4 full the gauge would then read correctly and the service engine light would go off.

  • Automatic transmission
  • 50,000 miles
The contact owns a 2006 Buick Rainier. The contact stated that after refueling, the fuel gauge would not read the actual level of gasoline in the fuel tank. In addition, when refueling, the pump would shut off before the tank was half full. The vehicle was not inspected by a dealer or repaired. The dealer was contacted and they informed her that they are aware of the failure. The failure mileage was approximately 50,000. The VIN was unavailable. Updated 09/01/2011

Rainier

  • 57,600 miles
The contact owns a 2006 Buick Rainier. While parked, the contact refueled the vehicle and noticed that the fuel gauge indicator was fluctuating in between readings. The vehicle was taken to the dealer for diagnostic testing where the technician indicated that the fuel level sensor needed to be replaced. The vehicle was repaired. There was an open investigation under NHTSA action number: PE11014 (fuel system, other fuel system, other:storage:fuel gauge system) that could potenitally have been related to the failure. The approximate failure mileage was 57,600.

Rainier 6-cyl

  • miles
Fuel gauge on our 2006 Buick Rainier does not display the correct reading for the amount of fuel in the tank. It frequently reads empty when the tank has been filled, and then reads anywhere throughout the range of the gauge, changing while driving and or when shutting the vehicle off and re-starting. We never get a correct reading of the gauge, and therefore never know when we may run out of gas. The problem started during the fall of 2010 and remains to this day.

The gas gauge began reading empty when it was actually full. When the tank was initially filled the gauge read full, then go down gradually while driving until the gauge read empty. When the tank was full the service engine light would also light until the tank would be at approximately 3/4. at 3/4 full the gauge would then read correctly and the service engine light would go off. About two weeks ago the fuel gauge stopped working completely and only reads empty now.

Gas gauge began to fluctuate several months ago. Once down to a half tank, gauge would read empty. Now the gauge reads empty at all times, have to use odometer to figure out when to get gas. Bought from a friend who owned four as company cars, and he found out that all four began doing it.

Rainier

  • 58,000 miles
Erratic fuel gauge beginning in Aug, 2010. Always fails after complete fillup. Sometimes operates below 3/4 tank. Currently not operating at all for past 90 days. It is showing "low-fuel" warning light irreguardless of the amount of fuel in the tank, the gauge needle remains on empty. There is no way to know how much fuel I have or when my 2006 Buick Rainier will run out of fuel.

Rainier 6-cyl

  • 56,000 miles
The fuel gauge on my 2006 Buick Rainier is malfunctioning. The problem started about 6 months ago and is now continual. It does not give accurate fuel levels. Sometimes when the tank is full, the gauge reads empty, and vice versa. This is most definitely a safety issue !!! I was on the freeway the other day and ran out of gas (even though the fuel gauge showed nearly half-a tank.) this could've resulted in serious injury or death to myself and/or others. As I understand it, there are many instances of fuel gauge malfunctions on GMC cars of this vintage. There needs to be a government mandated recall of affected vehicles before lives are lost because of this component failure. My Buick dealer wants over $500 to correct this problem, which is not the result of wear and tear or carelessness or misuse on my part, but rather the failure of a critical safety device. The consumer should not be required to bear this financial burden.

Rainier 6-cyl

  • 83,500 miles
Fuel gauge is intermittent, registers low or high at different times when tank is known to be full or near empty. Cannot be depended on to give accurate information. Registers higher than actual at times, lower than actual at times. Several times before discovery of the problem we have been at risk of low fuel levels that were discovered when refueling. Intermittently continues.
