There are 10 owner-reported fuel system complaints for the 2018 BMW X5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
On July 9, while accelerating on a busy freeway during rush hour, the car stalled in the middle lane and was unable to be driven off to the side. I called 911 and a tow truck came to tow the vehicle. The problem was diagnosed by BMW as the high pressure fuel pump, which was determined to have blown out and sent metal into the entire fuel system - with a repair estimate of $26k. The high pressure fuel pump had already been replaced by BMW under a recall and the remedy was to replace it with the same faulty component, which failed again. There was no warning or signs of impending failure. The 2018 BMW X5 has been serviced solely by BMW and inspected multiple times with no suggestion there were any issues. I called BMW after the incident, and since the car is 3k miles over the extended warranty on this part, they have denied any help in remedying this issue.
