Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The 2021 Buick Encore was listed by the NHTSA as having a parts recall with the Evaporative Emission Purge Pump, yet when I look up my VIN and talk to the dealer, I’m told the vehicle is not recalled, even though I’m having the exact same issue that was described in the recall. I’ve been delaying servicing because I was told the part was on back order but now they have it in stock and I’m hoping I don’t have to pay for it since my issue is the same one that was listed in the recall.”
