2013 BMW 550I Fuel system Problems

“Takata recall I have a 2013 Bmw 550I xdrive m sport. It keeps on misfiring on cylinder number two and I have changed all 8 spark plugs and the injector for that cylinder. I also used octane booster and sea foam to clean the carbon out the fuel system. I don't know what else it could be if it's still misfiring on that cylinder. It starts up good and sometimes it starts up kind of hesitant. When I come to a complete stop after really going fast it starts to shake as I am stopped and when I go to take off it lurches sometimes. …”

“The complaint is not a safety issue. It's a quality issue. Bmw's n63 engine is evidently not well engineered. They have a customer care package ' in place for those customers that complain to the service dept about their engines not running right. Bmw is very careful to make sure customers do not view the repair as a recall. That said the amount of work required is extensive (takes more than 1 week to complete). From what I've read online the fix they have in place does not always work. …”

“After having made several replacements to parts (e.g. All three fuel pumps) to this vehicle over three, the vehicle now requires a new engine due to the failure of a rod ring. The root cause for this failure remains unidentified, however Bmw is refusing to identify and/or accept accountability to address this failure which requires an engine replacement (>$13000). Any vehicle of this age (~7 years old) and mileage (~80,000 mi.) should not require an engine replacement. Fortunately this issue occurred while traveling on urban roads at speeds less that 50 MPH. …”

“While drive below 30 MPH, the front driveshaft broke and ruptured a hole in the engine's upper oil pan. The flexible joint or universal joint seized and broke the front part of the front driveshaft. Then the vehicle had metal in the engine oil and that has damaged the engine and the turbochargers. The vehicle is going to need a new engine, new turbochargers, and a new front driveshaft. The repair estimates are: new engine - $3800.00 turbo chargers - $1100.00 front driveshaft - $1500.00 auxiliaries parts - $1200.00 labor/repair cost - $7000.00 total cost - $14,600.00”

“The contact owns a 2013 BMW 550i. The contact stated while driving 50 MPH, the warning message illuminated on the instrument panel stating, “Driving moderately and drive pit not available”. The vehicle was taken to the dealer and the high-speed fuel pump on the passenger’s side was replaced but the failure continued. The vehicle was taken back to the dealer and the high-speed pressure sensor was replaced. The manufacturer was not contacted. The failure mileage was 96,280.”
