The misfire detection monitor, a software strategy built into the computer, is designed to detect an engine misfire. The computer can also normally identify the specific cylinder in which the misfire has occurred. A misfire is nothing more than a lack of combustion, which can be caused by poor fuel quality or metering, low compression, lack of spark or unmetered air entering the engine. There are other possible, less obvious causes as well, such as uncommanded exhaust gas recirculation (egr), flow. When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.

Rental of 2014 BMW 320I in June 2014. Parked auto in level parking lot by placing foot on brake and depressing "park" button on gear shift, after which wife exited passenger seat to retrieve package in rear seat. When brake released to turn off engine, auto rolled forward onto wife's left foot, crushing it into the pavement under the weight of rear wheel of auto and causing her to fall hard on concrete pavement. Gear shift when "park" button engaged had gone into "neutral" one gear above "park." Because engine was turned off and has to be depressed twice very slowly - with space in-between each depression - or engine will not engage, rear wheel was crushing wife's foot for 1-2 minutes before engine would re-engage and auto could be rolled off her foot. Please note that 2014 mbw 320I gear shift has "park" in the middle of the gear shift, not at the top as is customary, with "neutral" one slot above "park." We tested putting the car in park several more times after the incident described above and nearly 50% of time when the "park" button is depressed, the gear shift slides forward one slot past "park" into "neutral." If auto were on a significant incline or if parked in front of concrete or barbed wire barrier with someone walking in front of auto when "park" button is engaged, mistakenly sliding into "neutral, " someone could be injured much more seriously or even fatally. We note previous complaints to the NHTSA regarding same gear shift defect in 7-series BMW's made between 2001 and 2008 that resulted in a class action lawsuit, which was dismissed because plaintiff's failed to prove that BMW knew about the problem. That can hardly be a legitimate excuse in this instance with a BMW 320I made in 2014.

This BMW has approximately 16000 miles on it (was purchased last year). Car was being driven first time that day. Car was stopped at a traffic intersection. When light changed and gas was pressed, the car made a stuttering noise and moved a few feet and stopped. The dashboard indicated drivetrain malfunction and transmission overheat. The car would not restart and was towed away to a BMW dealer. After a few days of back and forth about software reset etc, the dealer worked with BMW to determine that the transmission had to be replaced. This could have been dangerous as the car was in a very busy intersection when the failure happened. It is surprising that the failure happened this early in the car's life. The dealer attempted to reassure us by saying that this failure happens more often than people think (which made us even more concerned).

While driving on the highway the vehicle stopped accelerating and the power train malfunction light came on. The vehicle was undrivable and could only be coasted to a safe position. This is the second issue with the electronics on this car, the audio system had a short in it as well a few weeks after it was purchased with only about 800 miles on it.

The contact owns a 2014 BMW 320I. After parking the vehicle with the brakes engaged, the transmission shifted gears independently. The failure occurred multiple times. The dealer stated that the floormats depressed the accelerator pedal and caused the vehicle to shift to other gears. The manufacturer was notified of the failure. The manufacturer performed an investigation confirming the dealer's diagnosis. The approximate failure mileage was 17,000...updated 12/17/14 updated 9/29/2015
