NHTSA Complaint #11473091 — 2017 BMW 330I

We had a 2017 bmw 330i x-drive. It had approximately 67000 miles. The car stalled while driving about 6 times. The first time was in 3/2021. The diagnostics were for a faulty high pressure fuel pump. We replaced the HPFP. It stalled again while driving. The diagnostics were for a faulty low pressure fuel pump. We replaced this. The car then stalled while driving 2 more times. The car stalled again in 10/2021, and we towed it to the dealer, who diagnosed a problem with the electric fuel pump control unit., which the dealer replaced. We brought the car home for one day, and we had the same problem again. We brought the car back to the BMW dealer, who diagnosed a problem with the VANOS system. The BMW Peabody dealer directed us to BMW corporate for evaluation of available warranties and rebates given the nature of the problem (VANOS) being warranted under the California SULEV emissions standards and the fact that they dealer had diagnosed a separate problem the day before. We sent the diagnostics and the SULEV warranty info to Sean, as everyone at BMW seemed unaware of its existence and who was responsible for following it. He took weeks “looking into it,” and the dealer repaired the VANOS during this time without a final answer from corporate. A car stopping while driving is clearly dangerous to the occupants and surrounding vehicles. BMW did not honor the SULEV warranty, which clearly covers the VANOS and the fuel pumps until 70000 miles. The car was traded to BMW Peabody, as we no longer felt safe driving it. We do not know if the replacement of the VANOS fixed the problem.
