“My vehicle has 64,000 miles and I was exiting the driveway and accelerating up to 45mph when all the sudden I encountered a complete loss of power with sounded like a bang in the engine. My car immediately slowed down to under 30mph and started shaking. Luckily I was only 2 minutes from my house.

“On 7/9/14, I backed our new 435I up to our garage (outside for the night). The garage door was open, and the warning system let me know that I was close to our lawnmower. Once I was close enough, I put the car in drive to straighten out the car, and immediately the vehicle attempted to accelerate to full speed. I was already on the foot break, but the car would not respond. Our driveway is concrete and quite slick. The rear tire spun uncontrollably, created a cloud of smoke, and left a pile of tire debris behind the vehicle. I hit the kill switch and refused to drive the car further. …”

“There is a major design flaw on the Bmw 435I 2014 to people who live where there is rain. I was pulling into the parking lot of my company and there was a puddle from the ran maybe 5-6 (not enough to penetrate the doors and wet the inside) . I drove through the puddle and the engine hydrolocked causing the engine to have to be replaced. I was told by the service department that the car is low to the ground and that the air intake is on the front grill at the bottom. With this car being low, how can anyone drive in rain in an area where water accumulates? …”
