“Rear tail light connectors melt just like a recall of previous 3-series Bmw's. Nhtsa campaign id number: 11v438000. Getting notification of blinker failure, dealership notified me that the connector had melted and needed to be replaced at my expense. The light bulbs are stock and have never been replaced.”
NHTSA complaint #11163589, filed 2018-12, 48,000 miles“Every time I go from i93 mass to i90 hwy on the exit my car shuts off for 3sec and restarts the electronics. Not sure what defect or sensors are in the area that causes this malfunction. But this only happens when I take the same exact exit every single time.”
NHTSA complaint #11362496, filed 2020-10, 58,000 miles“Driving on 4 lane road at 40mph when 2104 Bmw 335I xdrive vehicle experienced total failure-starting with the navigation screen then the entire dashboard went black and engine shutdown (all in few seconds). There was no shoulder (concrete curb) so vehicle came to stop in the right lane. Headlights were stuck on but nothing else worked including the emergency flashers! Contacted Bmw assist but they were unable to help but sent out police and tow truck. Car would not shift into neutral and was dragged onto a flatbed damaging the vehicle. This was extremely frightening! …”
NHTSA complaint #10669921, filed 2015-01, 7,500 miles“After the car is shut off, the coolant pump will stop with the car but after a min the car will stay off but the coolant pump will kick on. Runs until battery is drained. I do understand there is a feature to circulate the coolant so help mitigate burn/hot spots but this continues until the battery is disconnected by ECU. Then it won't start because the battery is too low. Ongoing issue for the past 2 years now, happens intermittently. Frequency is random but happens more when it's cold out. …”
