One problem related to crankcase (pcv) has been reported for the 2012 BMW 528. The most recently reported issues are listed below.
On a rainy October 13, 2018, while riding on the highway(rte. 422) with my 7 year old son my BMW 528i stopped running; without warning. Miraculously, we coasted on the highway ramp into the dealership driveway. The vehicle was diagnosed with an internal engine failure, which required $12,000+ to rebuild/repair. Currently, the payoff is $13,895. 32 till 11/25/18. The monthly payment is $425. 00 and the date of maturity for the loan is 9/15/21. I purchased the vehicle under a pre-owned certified guarantee, which expired in July. The car was regularly serviced and I kept all of my paperwork. Upon researching the engine failure, I discovered that this is a common problem. In fact, presently, an acquaintance of mine has his car at the BMW cleveland dealership with the same problem. These engines suffer reliability issues that result from problems relating to the timing chain, fuel injectors, mass airflow sensors, crankcase vent lines, battery, the engine vacuum pump and low-pressure fuel sensors. Such problems led to more serious concerns such as excessive battery drainage (the �battery defect�), oil leakage (the �oil defect�) and engine seizure, often causing pistons to crack the engine block due to the high pressure (the �engine defect�). Additionally, the engines experience internal engine failure due to loose metal shards in the engine. My question is. . . How did the vehicle pass the multi-point inspection to earn the pre-certified designation?.
