Loss of power/won't Rev over 2500rpms No fault codes displayed on dash Radiator fan goes to max and cuts off consistently every 30sec-45sec Very dangerous situation when pulling out in front of traffic. I've only owned this car for 3 months! I need to get this fixed asap. Also, this problem occurs at random times in all different conditions. It will also "reset" after turning car off and restarting. It has happened to me 7 - 8 times in 3 months!

I loved my BMW until I realized it has a faulty engine. I noticed the drive train malfunction light once when I went through a car wash. I turned off when I restarted the car. My car was up to date on all oil changes etc, I take it to BMW specialist only. I noticed a light tick sound and reported it to BMW at my last oil change. They disregarded it and said they did notice oil on the gasket. No changes requested at that time. My car never showed signs of leaking oil and the oil pressure at times showed to be low but would always return to normal. I was told it was because the hybrids work differently. On my way home on the frontage road of I35 my car just shut down and never restarted. I was able to guide it into a parking lot and the engine just stopped turning and the drive train malfunction light turned on. I had it towed to a mechanic and they basically said they had to replace the entire engine. A new engine cost $18000 and a used is around 13000. That does not include labor!!! I had to then have my car towed home to just park it. This is the only car I have, I owe thousands on it and the engine completely broke! as I'm doing research I see multiple complaints with the same issues and same result, complete engine failure!!! this needs to be investigated! from what I gather it is related to the drivetrain malfunction light sending a signal to the engine & stopping oil from reaching the top of the motor, leading to vanos complications and leading to metal in the engine leading to a complete damage to the engine. Cheap issue leading to failure of the entire vehicle. I've also gathered there is a fault with the start/stop that causes this issue. I am left with no car, I'm a full time nurse and now in debt with no working car! this could have been prevented had a recall been done a few years ago with all the initial complaints!! several forums including on this site!!

The door lock actuators have failed. This makes it so that the doors do not open when you are inside the vehicle attempting to get out by pulling the door handle. This is a safety issue not allowing me to get out of my vehicle. If this issue is not resolved by paying the $1500 to fix the issue the doors will stop opening completely making this even more of a safety issue over time. This issue only gets worse and is directly related to the functionality of the car. This door lock actuator should be recalled on all vehicles BMW makes that are having this same issue. This is a known long-standing issue with these vehicles and has yet to be recalled even though it is absolutely a safety issue. BMW should not be able to profit off of their poor safety manufacturing mistakes.

Driver and passenger trapped in car after parking at as gas pump. Doors would unlock but not open resulting in the potential of killing its passengers in a crash. There is a video on youtube of a similar incident.

When I try to open the drivers side door by pulling the handle it does not unlock automatically. The only way to exit the vehicle is through another door or by using the central lock/unlock button. My fear is that in the case of an emergency or accident if the electrical system is compromised I could possibly be trapped in the vehicle. I attempted to have this repaired at the BMW dealership but they claim that the problem being mechanical is not covered by the warranty. On the BMW internet forums there are multiple posts across vehicle models complaining of the same faulty "door actuator" and BMW's unwillingness to repair it free of charge. I was quoted over $950 to replace the part. This is a serious life safety issue I believe needs to be investigated. Thank you very much!

If cell phone placed on the passenger seat, it could cause a false seat belt light to illuminate. I noticed while charging my phone through the usb port and the phone is charging; I can repeat the incident over and over. It is unclear if the airbags are functional at this time. This could happen in motion at any speed (highway/city) or while stationary.

My husband was refueling our 2013 BMW 335I and I was in the passenger seat. During that process, a pickup truck backed up and was close to hitting our car. From the passenger seat, I tried to warn the other driver with our car's horn, but it did not work, so I resorted to screaming as loud as possible since the windows were also closed. Fortunately, my husband heard me and realized what was happening and got the trucks attention and prevented a potentially catastrophic collision right next to a gas pump. It never even crossed our minds at the time that a horn did not operate when the car's electrical system was switched off with the ignition key, which one must do for fire safety reasons when refueling. Nevertheless, after we got home we tried the BMW's horn when the car was off and there was no response. We tried our 2005 Subaru outback's horn with its ignition switched off, and its horn worked just fine. I searched on '2013 BMW horn does not work's' on the internet and the system returned 18,200 results. While I did not read all of them, I found numerous postings about BMW horns not working when the car is off, as far back as 2006. Some internet postings advised having the key in the ignition. I placed the key in the ignition and the dashboard display and I drive screen activated, but the horn did not. Next, I pushed the start button, without engaging the engine, and only then did the horn work. I contacted BMW assist for technical assistance and spoke to a BMW customer service representative in columbus, oh. He confirmed that the horn is operating as designed. He said he would enter my concern into the customer feedback database. We think being unable to warn distracted drivers about to crash into your occupied but parked car is a hazard at least worthy of prominent warnings to drivers of bmws and any other vehicle with this "feature".

The car goes into "limp mode" while driving reducing power immediately. I was making a turn onto a street crossing a highway and my car went into this limp mode. I was almost hit due to the sudden loss of power. Symptoms: 1) loss of power and car will not rev. Past ~3,000 RPM (no fault codes on dash) 2) radiator electric cooling fan on max (very loud) 3) engine oil temp. Approx. 205 degf or lower (while limp mode is occurring, temp. Is usually not at normal operating temp of 245 degf) the problem goes away once car is turned off and back on (it resets). Many users have reported that it seems to happen after a long comfort mode drive on the freeway followed by city driving and switching to sport mode. Repair attempts: 1) auxiliary electric cooling fan replacement (mounted to the radiator and fan shroud) - biggest culprit (the fan is tested directly and will fail the test but may or may not have a fault code stored in the ECU) 2) fan relay replacement 3) thermostat replacement 4) dme replacement with software update as far as we can tell, there is no sib yet but plenty of puma cases have been filed. A few people have had their cars bought back and replaced by BMW. Please look here www.F30post.com/forums/showthread.php?T=786475 there are 50 pages of this and BMW is not helping.

I was rearended, on the freeway, on the passenger side, by an SUV going about 40mph, I slammed in to another SUV in front of me. My vehicle is totaled. The display indicated that there was an airbag deploy error. Also, the reason my car was totaled was because all of the electrical wires for the computer system are behind the rear tail light, and they were melted after impact. This is concerning because this is also where the fuel tank is. Luckily, I walked away with a sore neck and few bruises, but it is concerning that the airbags did not deploy, when they were clearly suppose to. I had the car for less than 2 months prior to the accident, and bought it brand new.

Auto start/stop function has malfunctioned before where when I take my foot off the brake, the car doesn't start again. Normally I can just press the start button and put it in drive. This time, however, I went to start it again after it had an "auto start/stop malfunction", and it wouldn't turn back on. An error popped up saying "ignition malfunction -- do not turn engine off. Car will not start again." Currently waiting to hear back from the dealership after I had to flatbed it. Also the car wouldn't go into neutral so they had to drag it on the flatbed.
