“The car had 14,500 miles on it when the problem occured. My wife drove the car to chicago and back , upon returning she parked the car in the garage removed some groceries the came back to get the rest and the car was smoking from under the hood. She then called me as I was not home and asked what to do, I told her to get the car out of the garage and because of the intense smoke said she was afraid so I told her to call the fire dept. Which she did. 30 minutes latter the car and garage and all contents were destroyed.”
NHTSA complaint #11338903, filed 2020-07, 14,500 miles“There is a rotten foul odor coming out of the car vents when the car is first started and the air conditioner is not turned on. The smell slowly disappears when turning on the air conditioner.”
NHTSA complaint #11245911, filed 2019-08, 13,000 miles“The heater blower ceased working. The back brakes needed to be replaced for a 3rd time, and the factory never sealed the air filter for the engine properly.”
NHTSA complaint #11397695, filed 2021-02, 49,000 miles“Upon start up, vehicle AC system releases foul musky smell for an undetermined period of time that's more prevalent during the summer/warm weather. Cleaning the AC evaporator core per Bmw service instructions only briefly alleviates the problem before the smell comes back full force again. This is a health concern as there is definitely mold, mildew or bacteria growing within the AC system. These germs are then getting pumped into a confined space, which will likely cause or exacerbate health conditions related to the respiratory system or breathing. …”
NHTSA complaint #11243574, filed 2019-08, 18,000 miles“While driving (car moving and in Drive) the rear hatch opened on the vehicle to about a mid-way position completely obscuring vision from rear view mirror. Fortunately I was able to pull to the side of the road and nothing fell out of the cargo area. Key fob was in my pocket - no buttons were pushed (on purpose or accidentally).”
