Example complaints

“A few months ago the vehicle started to display drive train malfunction on the screen while shaking with a horrible odor of fuel. I took the vehicle in to the dealer and was told all of the fuel injectors needed to be replaced! We are talking about a $100k+ vehicle barely out of warranty. After battling with the dealer I was told Bmw has agreed to fix the problem under warranty. When I went to pickup the car I was given an invoice for almost $500 for a deductible! …”

“While driving my car on highway 20 west my engine loss all power making my car slow completely down. I was in heavy traffic and I had to move over two lanes to get to the shoulder of the highway. Once my car stopped the car put its self in park and would not allow me to select any gear. Come to find out the turbo charger wen out in my car causing the car to act in this un safe manner. This is a reall safety issue that Bmw has on these particular engines. This matter needs o be addressed with my car please”

“A warning light for the passenger side front airbag is on. Bmw wants to charge me $1500 to replace the faulty airbag. How can it be damaged if it's never been used? How is this repair my responsibility? Additionally, this Bmw burns oil. It seems to be a problem with all 8 cylinder models as they age. I have to add a quart of oil every 300 miles or so and the car blows black smoke via the exhaust. I've spent $1300 to repair it, but it didn't repair the issue. Now I'm being told it's a $10,000 repair. How is a problem that's systematic with so many 8 cylinder bmws my responsibility?”

NHTSA complaint #11220935, filed 2019-06, 70,000 miles

“Bmw 650 n63 engine issues aka drivetrain malfunction (dtm) error has been a very common issue in these cars. If you do your research people with brand new cars with less than 100 miles have these issues as well. Long story short Bmw, na offered to buy back my car after spending more than 5 weeks in the shop for 2nd repair. First repair was the recall , Bmw offered as the customer care package . I purchased it cpo (certified pre-owned) w/ 26,000 miles., I was unhappy with the offer since they deducted mileage used. …”

NHTSA complaint #10808085, filed 2015-12, 29,000 miles

“Vehicle engine (n63) loses power while in operation and goes into a drivetrain failure mode reducing enging power substantially. This is a recurring problem in the car. Bmw is aware of the issue and has taken the car in to repair it 3 times. They recenly performed a customer care program to remediate the problem. But it occurred agian shortly after thet attempt. Bmw made a ruling today, that they will not buyback my car nor offer any other remedy. I specifically want the NHTSA to make an official recall of this engine as it is not repaired after widespread failures for this specific engine.”
