I purchased a pre-owned 2010 BMW 750li back in November 2012. As soon as I drove it off the beverly hills BMW lot, I got a check engine light go off. Beverly hills wrote it off as it was the gas sensor being sensitive. Found out later it was the fuel injectors that went bad on a car with 23,000 miles on. Fast forward 2 years later and 30,000 miles, with multiple stops at sterling BMW and my complaints of having to put quart of oil into the engine every 2000 miles. For 2 years, sterling advised me it was normal for this type of engine to consume that much oil and for all the other engine problems. I have brought the car in for over 6 times (ever other month almost) to the dealer to fix numerous problems with the engine (not normal wear and tear). Then comes the "recall" BMW calls the "comfort care package" and was promised it would resolve the oil consumption with better performance in January 2015. After the recall, my engine required oil every 500 miles and when I brought it back to BMW in April 2015, they advised me it was a hose leak and oil was dripping down to exhaust causing excess smoke from the exhaust. Now BMW of northern America tells me they don't cover the repair because it was our of warranty despite my complaints (which have been documented by sterling for 2 years). The comfort care package made my oil leak worst and into the exhaust and BMW refuses to repair the problem or even remove their comfort care package. It's been more then 2 years since I and my 2 year old daughter have been breathing in this excess smoke from my exhaust which BMW refuses to repair. This engine is a complete lemon.

The engine in this car (N63) has major flaws. At anytime while driving this engine can stall or reduce power. There are issues with the timing chains, fuel injectors, vanos system and other electrical engine parts. This car has been in for service a total of 57 days since April 2014 for engine failure. This car when fails will reduce power or shut down and you have no power to get out of the way of traffic. BMW fails to correct this problem. BMW is currently replacing some of the parts that they think might have some effect but not all dealers are assisting consumers and BMW will not recall this. This is a major safety issue as this N63 engine is used in all BMW vehicles fitted with a V8.

At 57,000 miles, my 2010 BMW 750li needed 6 out of 8 fuel injectors replaced. The fuel injectors for the N63 engine platform have been redesigned multiple times due to a high rate of part failure. The parts were poorly designed, and are failing prematurely on vehicles. BMW refuses to acknowledge the faulty fuel injectors and should properly issue a recall.

I was driving a BMW 750li 2010 on the freeway 70mph. Without warning, the engine stopped and the entire electrical system went off. I steered the car quickly to the shoulder. I only had enough momentum to pull my car to the side of the road. All systems were non responsive. I was unable to place the car in neutral for the tow truck. I was unable to call for assistance via the vehicles call system. I would have to assume that all the systems active safety equipment were useless since I had no power.

While driving on the parking lot the vehicle suddenly jerking around and engine stopped. When tried to run the engine it was shaking tremendously and engine was not running. So I towed it to the dealer next morning for repair. After repair was done which took a week I drove it for about 40 minutes and then when I applied the brake it was shaking alot again every time I was applying brake. I for somehow avoiding all stop sign by driving carefully, took the car home and took it to the dealer next morning at which time it was shaking tremendously or sometime moving forward fast(jerking move) when I applied brake or step on gas pedal.
