When entering the on ramp to merge onto the highway. I accelerated to merge into traffic and car vibrated violently and would not accelerate. I continued to press the accelerator but nothing happened and a message appeared on the display. Now, I'm stuck between the on ramp and the highway with a tractor trailer rapidly approaching. He barely has enough space to merge to his left and avoids rear ending me.this could have been catastrophic. I continued to press the accelerator and nothing happened. I put my hazards on and quickly read the message. It read, "maximum engine output not available." So, I turned the car off and restarted it, and it worked fine for a few hundred feet until I tried to accelerate. It did the exact same thing but this time it allowed me to creep along at 35 mph. I pulled over into the emergency lane and turned it off and on again, and it worked as normal. But this time I just continued to drive to work at 35 mph. During work, I scheduled a service appointment the next day. After work, I pulled out of my parking space and something popped and once again it stalled. After turning it on and off again, I was able to drive it home. The next day at the dealership, I was informed of the customer care package (recall). But what I didn't know at that time, the car had already been recalled with the previous owner. A lot of the same work was duplicated. Btw, this is a 2012 750li with 37,000 at the time of the second occurrence. The first occurrence happened at 29,931. It happened again 2 months later. This vehicle is unpredictable and you don't know when it will stall on you. The last repair reduced the powertrain output and takes a deep gasp before accelerating. Please read BMW's customer care service. The number of repairs are too numerous to list on the remainder of this thread.

The car engine was caught on fire in the parking lot. After driving from my house (about 3 miles), the car was parked in the mall. I went in the shopping mall for 10 minutes, and I went outside. My car was on fire. Fire department came, and he broke the hood to put out the fire.

- Orlando, FL, USA

This car experiences multiple drivetrain malfunction codes, looses power at intervals when driving, leaks oil from seals which creates white smoke from both the exhaust pipes and from underneath the hood. It also has a rough idle and every so often, the check engine light comes on. BMW should be ashamed of themselves for having these ongoing problems with their cars in this day and age.

- East Orange, NJ, USA

Drove car at approximately 8:30 P.M. car was left in the garage for the night. At 3:35 a.M. was awaken by my dog and smelled smoke, strongest in the area of the garage. Once extinguished by firefighters the car was pulled out. The left front number, headlight, and adjacent structures were melted. Extensive fire damage and smoke damage in the garage, and a lesser degree in the house. Cause of fire origin was not determined, but the car was not excluded. Concerned that this could be related to the auxiliary cooling pump issue noted in 2010 and 2011 models.
