Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Sometimes the blower motor will not work at the speed selected. A few times have smelled a odd burnt plastic smell. Bmw won't help this issue as there is no recall on this certain model. I have took the time to actually diagnose the issue. Wiring to blower motor resistor module affected. Cannot even unplug the connection. Has brown areas on the resister by ground wire of signs of extreme heat.”

NHTSA complaint #11104028, filed 2018-06, 126,000 miles

“The same blower motor wiring issue in the Bmw 3 series thats causing them to catch on fire and burn to the ground. I have compared the problem with another 3 series with the same exact issue. Although the wiring part number is different, the plug and where the negative and pos terminals are placed is the same exact spot as the 3 series. The car will shut off from voltage spikes when driving and cause sparks and arching noises where there neg and pos wires meet causing both of the wiring housings to melt and potentially cause a fire. …”
