Fuel Pump System Recall Buick: What Every Buick Owner Needs to Know
If you own a Buick vehicle, you need to be aware that General Motors has issued multiple fuel pump system recalls affecting hundreds of thousands of Buick models over the past several years. The most critical issue is that defective fuel pump components can cause your vehicle to suddenly lose power or stall while driving, creating a serious safety hazard. This comprehensive guide explains every Buick fuel pump recall, what symptoms to watch for, how to get your vehicle fixed for free, and what replacement options you have if your car is not covered.
Major Buick Fuel Pump Recalls You Should Know About
1. The Largest Recent Recall: Fuel Pump Control Module Failure (2024)
The most significant Buick fuel pump recall in recent history was announced in late 2023 and began rolling out in May 2024. According to official recall documents, this recall affects 611,260 Buick vehicles in China alone, but similar issues have been reported in North American markets.
The affected Buick models include:
- 2021 to 2023 Buick Envision S (昂科威S)
- 2021 to 2023 Buick LaCrosse (全新一代君越)
- 2021 to 2023 Buick Regal (全新一代君威)
- 2022 to 2023 Buick Envision PLUS (昂科威PLUS)
- 2022 to 2023 Buick Enclave (昂科旗)
- 2023 Buick昂扬 (Buick昂扬)
The Problem: The fuel pump control module has poor moisture protection. When the vehicle goes through water or experiences high humidity, water vapor can侵入 (invade) the control module, causing it to malfunction. In extreme cases, this leads to a complete loss of engine power while driving.
The Fix: Dealers will replace the fuel pump control module with an improved version at no cost to owners. This recall expanded from an earlier 2023 recall that only covered 74,295 Chevrolet探界者 (Equinox) vehicles.
2. 2020 Buick Enclave Fuel Pump Nozzle Blockage Recall
In October 2020, General Motors recalled 2,781 vehicles including the 2020 Buick Enclave due to a fuel pump manufacturing defect. This recall also affected the 2020 Cadillac XT5, Cadillac XT6, Chevrolet Traverse, and GMC Acadia.
The Problem: The fuel pump's jet nozzle had plastic burrs left over from the manufacturing process. These burrs could block the nozzle, preventing adequate fuel flow to the engine. At low fuel levels, the engine could stall without any warning.
NHTSA Campaign Number: 20V639000
GM Recall Number: N202314760
The Fix: Dealers replaced the entire fuel pump module. Owners were notified starting November 30, 2020.
3. High-Pressure Fuel Pump Flange Weld Failure (2018)
Another serious recall involved the high-pressure fuel pump potentially detaching from its mounting flange. This recall, announced in June 2018, affected 895 vehicles including the 2016-2017 Buick Envision and 2018 Buick LaCrosse.
The Problem: The weld joint on the high-pressure fuel pump could crack over time. If the pump separated from the flange, it could oscillate inside the engine compartment and damage the high-pressure fuel line, creating a fuel leak. A fuel leak significantly increases the risk of a fire.
NHTSA Campaign Number: 18V358000
GM Recall Number: 18268
The Fix: GM dealers replaced both the high-pressure fuel pump and high-pressure fuel pipe free of charge. The recall began July 2, 2018.
Why Fuel Pump Recalls Are So Dangerous
A failing fuel pump isn't just an inconvenience—it's a genuine safety risk. When your fuel pump fails, the engine doesn't get enough fuel to maintain power. Here is what can happen:
Sudden Engine Stall: Your car can lose power without any warning signs. This is especially dangerous at highway speeds because other drivers may not have time to react.
Loss of Power Steering and Brakes: When the engine stalls, you lose power steering assist and power brake assist. The steering wheel becomes extremely heavy, and you need to press the brake pedal much harder than normal.
Risk of Rear-End Collision: A car that stalls suddenly in moving traffic is at high risk of being hit from behind. Even if you safely pull to the shoulder, you remain vulnerable.
Fire Hazard: In the case of the high-pressure fuel pump weld failure, a fuel leak can lead to an engine compartment fire, which can be catastrophic.
How to Check If Your Buick Has an Open Recall
If you own a Buick, you should check for open recalls immediately. Here is how:
1. Use the NHTSA Website: Go to www.nhtsa.gov/recalls and enter your Vehicle Identification Number (VIN). You can find your VIN on the driver's side dashboard, inside the driver's door jamb, or on your vehicle registration documents.
2. Call Buick Customer Service: You can contact Buick directly at 1-866-608-8080 for U.S. owners. For Canadian owners, contact General Motors Canada.
3. Visit Your Local Dealer: Any authorized GM dealer can check your VIN for open recalls and perform the repairs at no charge.
Common Symptoms of a Failing Fuel Pump
Even if your Buick is not covered by a specific recall, you should be aware of these warning signs that indicate your fuel pump may be failing:
Engine Hesitation or Misfiring: If the engine doesn't get a consistent fuel supply, you may feel hesitation during acceleration or notice the engine misfiring.
Difficulty Starting: A failing fuel pump may not build enough pressure to start the engine properly. You might need to crank the engine longer than normal.
Whining Noise from the Fuel Tank: A healthy fuel pump makes a quiet hum. If you hear a loud whining or droning noise coming from the rear of the vehicle near the fuel tank, the pump may be failing.
Sudden Loss of Power at High Speeds: This is particularly dangerous. If your car suddenly loses power while driving on the highway, the fuel pump is a likely suspect.
Decreased Fuel Economy: A fuel pump that is not working efficiently can cause the engine to run rich (too much fuel) or lean (too little fuel), both of which hurt gas mileage.
What to Do If Your Buick Has a Fuel Pump Recall
If your vehicle is included in any of the recalls mentioned above, take these steps:
Step 1: Locate your VIN and confirm the recall status using the NHTSA website or by calling Buick customer service.
Step 2: Contact your local GM dealer to schedule an appointment. Be sure to mention that you are coming in for a safety recall repair.
Step 3: The dealer will perform the repair at no cost to you. Depending on the specific recall, the repair may take 2 to 4 hours.
Step 4: If you previously paid for repairs related to this condition, you may be eligible for reimbursement. Contact the GM Reimbursement Department at PO Box 33170, Detroit, MI 48232-5170 with your receipts.
Special Note for California Residents
If you live in California, be aware that the California Air Resources Board (CARB) requires emission-related recalls to be completed before you can renew your vehicle registration. Uncorrected emission recalls will prevent you from renewing your California registration. After the recall repair is performed, the dealer will issue a "Proof of Correction Certificate" that you must keep for your records.
