General Motors has issued an extended evaporative emission purge pump warranty period for certain units of the Buick Encore and Buick Encore GX due to the potential to fail.
Certain units of the 2020 Buick Encore and 2020 / 2021 Buick Encore GX may have a condition where the evaporative emission purge pump could fail. If this were to occur, affected units could trip the Malfunction Indicator Light – or the Check Engine Light – and set a Diagnostic Trouble Code (DTC).
As a result, General Motors will extend the warranty coverage on affected vehicles from two years or 24,000 miles (whichever comes first) to a period of 15 years or 150,000 miles (whichever comes first) from the date the vehicle was originally placed into service. Notably, California vehicles have a standard warranty period of three years or 50,000 miles (whichever comes first).
It’s worth noting that owners who paid for the repair service themselves may be eligible for reimbursement. Additionally, if the evaporative emission purge pump were to fail, GM certified technicians will replace the emissions equipment as necessary, free of charge.
There is quite an extensive list of vehicles eligible for this extended warranty period, including (engine code in parenthesis):
- 2021 Buick Encore (1.4L I4 LE2)
- 2020 Buick Encore GX (1.3L I3 L3T or 1.2 I3 LIH)
- 2021 Buick Encore GX (1.3L I3 L3T or 1.2 I3 LIH)
- 2020 Cadillac CT4 (2.0L I4 LSY)
- 2020 Cadillac CT5 (2.0L I4 LSY)
- 2020 Cadillac XT5 (2.0L I4 LSY)
- 2020 Chevy Blazer (2.0L I4 LSY)
- 2021 Chevy Silverado 1500 (2.7L I4 L3B)
- 2021 Chevy Trailblazer (1.3L I3 L3T or 1.2 I3 LIH)
- 2021 Chevy Trax (2.0L I4 LSY)
- 2020 GMC Acadia (2.0L I4 LSY)
- 2021 GMC Sierra 1500 (2.7L I4 L3B)
Claims filed on or after July 28th, 2023 for any of the vehicles listed above will be covered.

My 2020 abuick Encore GX has this issue; has tripped the check engine light. How do I go about filing a claim?
Go to a buick dealer. They will complete the diagnostics order parts and repair. Should be no charge. Buick extended the warranty.
Just had my purge pump crap out on my 2022 encore gx and 2 dealers told me to pound salt I went out of warrenty in beginning of October and mileage is 15500 total don’t buy gm products I had a Chevy trailblazer with less mileage than this with loud engine knock and traded in for this piece of junk thank you very much 2 in a row and I lost my shorts on trade in
2020 encoreGX been waiting 2 months for part. Very disappointed in lack of service from GM shame
2021 Buick Encore GX, check engine light on, part ordered last week.
Same issue with my 2020 encore gx. Part ordered a month ago. We are headed into colder weather and the remote start will not work due to the check engine light on. I can locate the purge pump on line… Not sure why Buick can’t. I don’t blame the dealer. This is on Buick and GM.
For those who had the part replaced… what is the part # and how long did the part take to come in?
Mike. It took about a month. I do not know the part number. Had Buick dealer replace the pump under warranty.
I have a 2020 Encore GX in Coral Springs Buick service since 3-25-2024 waiting for a purge pump to be shipped to them, very frustrating.
Inherited a 2020 Buick Encore GX. First, the turbo goes out. Takes a month to get the part and fix. Next, the engine light comes on. It’s the evaporative purge valve. Got it fixed. The light indicates again. Now it the evaporative purge pump. Nationwide shortage on the part. You know what I did? I traded that in with the engine light on. Good bye.
My check engine light just came on my Buick Encore GX and I need the EVAP purge pump fixed for wherever the leak is at.
But, I did not file a claim for this? It is now July 2024
Check with a buick dealer. They extend the warranty for the purge pump.
