Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin provides diagnostic tips/steps on testing for possible EVAP leaks in the system to correct a customer concern of an MIL Illuminated with DTCs P0442 and/or P0455 Set.
full bulletin at NHTSA ↗This Preliminary Information communication provides information to the technician about engine block of possible cylinder bore damage, scoring or out of round as the possible cause of engine oil consumption, misfire, cylinder leakage or blow by. Technician will need to inspect the engine for Cylinder damage or scoring, An out of round cylinder bore, Dirt intrusion, and Catalytic Converter failure.
full bulletin at NHTSA ↗This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use. Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement. This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days.
full bulletin at NHTSA ↗This informational bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

The failure pattern owners describe
The 2005 Buick Rainier has a persistent fuel gauge sensor malfunction affecting these vehicles across the mileage range. Owners consistently describe inaccurate fuel-level readings: the gauge displays empty when the tank is full, reads half-full at unexpected times, or sticks on E permanently. Low-fuel warning lights illuminate immediately after fill-ups. Some gauges bounce erratically between empty and full, making it impossible to know actual fuel state.
The problem creates real danger. Multiple owners report engine stalling without warning—one at highway speed in the fast lane with no prior warning, forcing a risky emergency lane change. Others describe the vehicle refusing to move when the fuel gauge falsely indicated empty. Several owners ran out of fuel on the road and were stranded despite believing they had adequate gas. Safety inspection failures have resulted because the fuel gauge defect is considered unsafe.
Owners note the defect affects related GM vehicles (Chevy TrailBlazer, GMC Envoy, GMC Yukon) and that an NHTSA investigation is ongoing. GM issued a technical service bulletin covering 50% of repair costs—acknowledged by owners as proof the manufacturer knows of the problem but stops short of a full recall. Repair costs cited range from $200 to $550 and typically require fuel tank removal.

Failure modes owners describe
Fuel gauge sensor failure with inaccurate readings
The fuel gauge sensor fails to report accurate fuel tank levels. When owners fill the tank, the gauge reads empty, half-full, or anywhere in between; the gauge may then stick on empty or fluctuate erratically (jumping between empty and full). Low-fuel warning lights illuminate despite a full tank. In some cases the gauge moves slowly after fill-up or bounces unpredictably throughout operation.
When: Failures reported between 47,500 and 120,000 miles; owners cite the problem appearing within the first 3–5 years of vehicle operation.
Symptoms owners cite: Gauge displays empty when tank is full; Gauge shows half-full or incorrect level after fill-up; Gauge stuck on E (empty); Gauge fluctuates or bounces between empty and full; Low-fuel warning light on despite full tank; Gauge moves slowly to show full after initial fill-up; No warning before fuel is actually depleted
Repairs/costs cited: Fuel pump module assembly or fuel level sensor replacement. One owner reports dealer quoted $535 repair; another cites approximately $550 out-of-pocket at 55,000 miles; another reports $200 out-of-pocket cost. Repair typically requires draining and removing the fuel tank.
Recalls/TSBs owners mention: GM issued a technical service bulletin covering 50% of repair costs (mentioned in narrative #3). Narrative #11 notes manufacturer assisted with repairs. No full recall issued; NHTSA investigation referenced (DP10001) but appears ongoing.
Engine stalling due to false low-fuel cutoff
In at least two incidents, owners report the vehicle stalling or refusing to move when the fuel gauge falsely indicates empty. In one case, the owner shifted into reverse to prevent a collision but the engine stalled; the low-fuel indicator was illuminated despite over half a tank. The vehicle had to be restarted to continue operation. A separate owner ran out of gas multiple times on the road due to unreliable gauge readings, resulting in stranding.
When: Narrative #2 reports incidents on 2/29/12 and 3/4/12; narrative #4 does not specify dates but describes multiple stranding events.
Symptoms owners cite: Engine stalls when fuel gauge shows low; Vehicle refuses to move or loses power during maneuvers; False low-fuel alarm triggers stalling; Multiple unplanned stalls due to inaccurate readings; Owner stranded on roadside with fuel remaining
Safety hazard: sudden fuel starvation while driving
Narrative #1 describes a critical safety event: with a full tank shown as empty, the engine died without warning while the vehicle was traveling at highway speed in the fast lane. The owner had to coast from the left lane to the shoulder, risking collision with other traffic. Narrative #2 reports a stall during a reverse maneuver on a busy street, with no traffic present at that moment but acknowledged as a dangerous situation.
When: Narrative #1 does not specify the exact date; Narrative #2 dates are 2/29/12 and 3/4/12.
Symptoms owners cite: Sudden engine shutdown at highway speed; No warning before fuel cutoff; Engine dies during low-speed maneuvers; Loss of power while in traffic
Recalls/TSBs owners mention: Narrative #1 mentions mechanic stated manufacturer may have offered financial assistance; owner references NHTSA investigation DP10001 and a petition for recall consideration. Owner notes vehicle failed safety inspection due to unrepaired fuel sensor.

What owners are reporting 2 most recent
Tl* the contact owns a 2005 Buick rainier. The contact stated that the fuel indicator gauge would read inaccurately, making it difficult for the contact to detect how much fuel was in the vehicle. The dealer diagnosed that the fuel sensor would need replacing. The manufacturer assisted the contact with repairs to the vehicle. The failure mileage was 102,000 and the current mileage was 112,000.
The fuel sensor gauge does not accurately depict how much gasoline is in the tank. When I fill up the tank it remains on "e" and the low fuel indicator light is on. The gauge will fluctuate up and down and never go all the way to "f". I am very upset that this problem is so prevalent yet gm will only cover 50% of the expenses. It is unsafe to not know the correct amount of fuel in one's…
