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. I believe this part should be recalled because looking at all the complaints with other owners they have the same problem this is a plastic piece that under where in tear and pressure which is designed for it is failing. Some of the stories I've heard are pretty scary also like people being on the highway in this happening.

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? I was never warned or informed of this situation. I have worked at my company for 16 years and have had over 6 cars and have never had to worry about any puddle at the driveway of my business. This is absolutely ridiculous.
