2006 Buick Rainier fuel system problems

Filed Jan 26, 2022 · Fuel system · CO

In driving cross country, filled up the fuel tank and resumed travel when the fuel gauge immediately went to empty (I didn’t even have time to drive up the highway ramp back onto the highway). The alerts started ringing and blinking and dash board told me there was no fuel. I went to a gravel area and inspected the engine compartment, under the car and the interior to be sure I was not missing anything, then restarted the SUV. Could not find any issues anywhere, including leaking fuel. I took off the fuel cap and reattached it to be sure there was no problem there. I had no choice but to get on the highway and continue my journey. The problem continued for the following 1000 ish miles. When I got home I contacted my dealer and set up an appointment to look at vehicle. They found the vehicle needing a sensor kit which was a recall back a few years ago. I had the issue repaired which took 3 days. They may have the removed items. Attached please find the invoice from the repair that shows the message numbers, etc from the inspection prior to and during repair. Since this issue was a recall, but I understand not for my vehicle but for many similar SUV’s and Pickups of the same area of manufacture; I feel the same components were used in my vehicle and should be paid for and included in this recall. Attached please find the invoice if I can figure out how to get it attached to this type of format.

The fuel sensor for my 2006 buick rainier started to malfunction approximately two years ago. I had it diagnosed by gm dealer, king chevrolet buick gmc of longmont, colorado and they informed me the car needed a new fuel sensor. The fuel gauge indicates the tank is empty, when actually full. We decided not to correct the problem, due to the cost. The buick ran out of gas numerous times throughout the last 2 years. Three days ago the car stalled on interstate 25 with passengers on board. We towed it back to king chevrolet buick gmc, longmont, co. And now diagnosed with a faulty fuel pump with an estimated cost of $1400 to correct the fuel pump/sensor problem. Each time the car was diagnosed by the gm dealer, not a word was mentioned by staff/technicians about the known fuel component failure. I discovered this issue after searching the internet, yesterday. I find it hard to believe that this serious safety hazard is not publicly acknowledged by gm corp and its dealers and a recall for these vehicles has not occurred. Seems gm corp and king chevrolet buick gmc have no concern for consumer safety.

The fuel gauge stopped working and the check engine light came on at about 65k miles in february 2009. I took the vehicle to the dealer where I purchased and was told that the fuel sensor inside the gas tank had failed and that the repair would not be covered under warranty because the 60k miles had been exceeded. Not being able to afford this costly repair has forced me to continue to use the trip meter on the odometer as a way to estimate my fuel level. It is now 4 years later and I have never received any notice of recall or service notice from the manufacturer or dealer. The vehicle now has over 125k miles and apparently no longer qualifies for the offer from gm of splitting the repair cost with the customer. I have not received any notification from gm or my dealer of any offer of assistance with this issue. Gm obviously installed faulty equipment and the fact that they expect their so called valued customer to pay at all for correcting this type of issue is not good business practice. I guess that I'm not that valued a customer as I brought this issue to their attention in 2009, repair was denied under warranty and I have never received any service notice regarding this issue.

Fuel gauge showed more fuel than what was actually in fuel tank causing vehicle to stall while driving. Fuel gauge now reads empty at all times even when tank is full.

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.
