750 I 4.4L

  • Automatic transmission
  • 98,251 miles


Three miles on the freeway and I get a critical error message on my 2012 750i with 98k miles... In a quarter mile I was able to pull off the freeway and turn the car of. I let it sit a few minutes and restarted it. As many have describe the motor sounded like a cement mixer with rocks in it (shaking and grinding badly). Luckily, I was able to drive it 1 mile to my local private BMW shop, and the next day he tells me the motor is trash. Throwing many error codes and two critical knock codes. The local Dealer was no help, so I contact BMW North America. After a week they offered me $1k credit toward a new BMW or $1.5k toward replacing the motor ( a $15k+ job). Crazy this offer was sooo weak. Especially since they could see this is my third 7 series and 4th BMW.

I did a lot of research, there was a class action lawsuit and the $1k/$1.5k is the standard offer as well as a new battery (separate issue) and 3 oil changes… But nothing to make the customer whole. In 2017 they did the N63 Customer Care Package – Bulletin B001314 on my car, and all service was done at the BMW Dealer. I bought the car about 18 months old as a CPO from a BMW dealer with a 5-year 100K warranty. the 5 years expired late last year. The car is not worth fixing, even at the low rate the local shop quoted ($9k for new motor installed). I just can’t believe BMW would let this happen, but they have. Lesson learned, don’t buy a BMW or don’t drive one out of warranty.

Any advice?

750 LI 4.4L, V8

  • Automatic transmission
  • 85,235 miles

On July 22, 2020, while slowing down to make a right turn, my 2012 BMW 750li suddenly lost power and started making a loud clunking sound in the engine. I coasted into a store/gas station at the corner. Previous to that moment, it jerked a couple of times but stopped doing that. Prior to this incident, my BMW had been in the repair shop for excessive oil loss. I had the rear main seal and oil pan replaced. I also had the oil changed. Now, I am stuck with a blown engine.

The auto repair shop filed a claim against its insurance company. They denied the claim based on prior history of the oil leak. I have read multiple treads about engine/oil leak problems with BMW 750 series on this site. If anyone out there has found a resolution besides paying $10,000 to $15,000 for a replacement an engine, please let me know. This should not be happening to an elite fleet car of the BMW brand.

750 750 I

  • Automatic transmission

This vehicle has a "care package" which in other words is a recall by BMW on major engine components. This problem occurred only 6 months after BMW did this "care package" and took apart the engine. I was driving down a local street at 35 mph, suddenly the steering column locked and a ABS Chassis stabilization warning showed on the screen. Pulled over in the shoulder turned off the vehicle and it would not restart. Had it towed to BMW, turns out the engine seized. They told us that the engine along with the twin turbos and radiator (hoses and gaskets included) would all have to be replaced. Knowing that BMW had just taken the engine apart just 6 months earlier there is no reason for the engine to have failed. We contacted BMW North America (corporate) and got them involved. We had to pay $15,000 to have all the work done. EXTREMELY DISAPPOINTED in BMW North America and have totally lost faith in the ultimate driving machine. Considering this is supposed to be the best luxury vehicle there should be no reason that at 85,000 miles the entire engine would seize, and that too shortly after BMW certified mechanics took the engine apart.
