2020 BMW 2 Series Reliability Report

Parked cars move unexpectedly in two reports. One rolls forward with no one inside and hits a garage door. Another accelerates backward into a brick wall when the backup assist feature disengages partway through. Over-the-air software updates download but fail to install, including one meant to fix the head-up display position. Other reports cover a panoramic sunroof shattering while driving, a failed lower active grille that the manufacturer declines to cover, and an open recall with no parts available.

Only a few reports, with no clear pattern. A front tie rod buckles while backing into a parking space at low speed with no impact, leaving the car unable to steer properly and needing a tow. One crash report with an injury describes the drivetrain locking up on the highway after a dealer repair. Another owner suspects a tow truck damaged the axle while dragging the car.

Headlight housings fog up in rain, scattering the low beams so they light only 15-30 feet ahead. The dealer could not replicate the problem once the lenses cleared, and the failure came at about 34,000 miles. Other reports concern the instrument cluster: no indicator shows whether the low beams are on, so a driver may run on daytime lights with the taillights off, and a light sensor dims the digital gauges until they are hard to read in daylight.

Only two reports. One describes losing power steering assist and the car shutting off while driving, ending in a crash that totals the car. The other is not a steering failure at all. That owner describes a fire-risk recall letter, months with no response from the manufacturer, and uncertainty about whether an independent mechanic can service the car while the recall stays open.

Neither report points to a factory structural defect. One describes a hand injury while reaching through the grille to find the secondary hood latch. The other involves a used car that sways side to side and shows multiple warnings soon after purchase, including reduced driver assistance and a check engine light. Service later finds the car had a prior accident and a critical structural safety problem.

Overheating warnings come with coolant loss, and in one case the engine stalls while pulling in. One car leaks coolant under the engine and the warning returns the same day, yet the dealer cannot locate the leak. Another needs a long list of repairs at an independent shop, including hoses, the oil filter, the PCV system, and the valve cover gasket. These reports echo the coolant leaks described under the engine category.

Both reports describe pressing the brake pedal and the car failing to stop, with no warning light. One low-speed failure ends in a rear-end crash with two people injured, and the dealer finds no fault before the problem returns. The other is traced to a failed brake booster at about 86,000 miles and repaired. Two reports are too few to show a pattern, but the loss of braking is a serious crash risk.
