My BMW had a pinhole in the radiator caused by driving on the highway and being impacted by a small foreign object. Apparently a foreign object (rock?) impacted the radiator creating a tiny leak. BMW repaired the vehicle (new radiator) and installed a "Rock Guard" without discussing this new Guard with me. Rock Guard Part # 17-11-8-185-042. This $1,900 repair is a known defect in the design which is why BMW adds the Rock Guard when replacing radiators. After the repair, research indicates this is a common issue for this model car.

Owner report 11512133 · 2023-03-16 (March 16, 2023)

While driving down the interstate I-65 South, my sunroof spontaneously exploded. It sounded like a bomb explosion inside my car and could have caused grave danger to myself. There was nothing dropped on my sunroof as the screen remained intact and closed with no damage. This was an upward and out explosion of my sunroof, which I feel is a defect and should have been the responsibility of BMW. However, the car manufacturer is prepared to charge me $2,719.05 to fix. This I believe is a defect. How does a sunroof explode spontaneously? Please help…

The rear cross traffic alert system is a major safety issue on my 2024 BMW M340i. It basically does not operate. To get any kind of notification that there is a vehicle approaching from either right or left if you are backing up the approaching vehicle has to be traveling at a speed greater than 7 mph and then you only get an alert within 2 seconds of impact. This is a pointless operation as then it is too late to avoid a collision. The window is to narrow to provide any useful alert and safety function. Also, I receive no alert if a pedestrian…

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
