Electrical system

6 reports2 crashes1 related recall
“Check Engine light on due to lower radiator blind jammed and closed. BMW has extended car warranty for this fault for various other models produced 2020 and beyond for up to 150,000 miles, under si B01 03 25 and si B01 12 19 However They do not cover my car, 2020 BMW 530e which has 78,000 miles where most of their 5 series and 3 series are covered under extended warranty for this exact problem for 150000 miles or 15 years. This is an emission part and jamming of flaps put at tremendous risk of car catching fire while driving due to heat. They must cover all their car for this manufacturing defect including 530e models.”

Exterior lighting

2 reports
“The car’s instrument cluster has no indicator light to inform the driver whether or not low beam headlights are active. I took the car into BMW to get this addressed early on after purchasing the vehicle and BMW service technicians informed me that these cars don’t have such a light. Even though the manual includes documentation for the light. This poses a safety hazard as a driver may put the headlight switch in the wrong position and would have no indication they’ve done so. Daytime running lights may confuse them to thinking they have their headlights on. This poses a safety risk as tail lights would also not illuminate reducing visibility for other drivers and could increase the likelihood of a collision.”

Power train

“Last year around this time my differential failed and I lost all power to my wheels when driving in traffic in [XXX] on my way back to [XXX]. The car was driving and a loud clunk sound came from the car and the transmission wouldn't drive and I had to coast off the road cutting off cars to make it to a parking lot. I thought this was just something that happened to my car that maybe I did but then I saw the recall going on for the BMW differentials and realized It wasn't just a one off thing that happened to me. The vehicle was towed to a shop by AAA insurance and was looked at and confirmed to be the differental and driveshaft. I already had the problem looked at and fixed and I have documentation of everything. The only warning signs I noticed before it happened was a clunking noise and feeling like the wheels had a problem with putting power down to the road and I heard it and felt it and it got worse before it broke but I didnt realize what it was until I was actually stuck in [XXX] after it broke. My vehicle isn't included in the official recall but I would like help to get it added because I belive I suffered the same problem and am hoping for…”
