I was turning on to a highway, as I accelerated to match the speed of oncoming traffic and merge, the engine power abruptly degraded. I had to swerve out of the lane to avoid an accident. The vehicle had a flashing service engine light and was not producing any power. I had the vehicle towed to park ave. BMW in NJ. The dealer diagnosed my vehicle with a failed dme (engine management computer or ECU) at less than 60K. After doing some research I found many others BMW N54 engine owners online who had encountered the same dme failure. It turns out an electrical component that costs a couple of cents was prematurely failing. This was known to BMW in 2007 when the vehicle was being sold. The BMW service builtin si B 12 18 07 clearly indicates that this is an unexpected failure and is caused by a defective diode. Further more the issue can damage coils and fuel injectors costing thousands of dollars. Replacing coils, injectors, and the dme can exceed $5000. Further more BMW chose no to be proactive and replace the component, instead they put peoples lives at risk, at best their benefiting from their own lack of quality.

BMW said they replaced and fixed the air bag issue and battery cable (positive) recall. It's been over 2 weeks and I just searched on safercar.gov and they both still show as open issues. Did BMW lie?

BMW 335I 2007 has (X3)three times now, the vehicle was traveling during the daylight hours at highways speeds of 65-70mph in the number 1 far left lane of (ca 101 fwy) in may of 2016 when the vehicle displayed ¿engine temperature was high, and that the car needed to be driven at a moderate speed¿. immediately took my foot off the accelerator and began to coast in idle state to the shoulder (ca 101 fwy) 5 lanes over. Before I was able to move to the 3rd lane the vehicle stated ¿engine to hot¿, turned off, lost power (much like if you run out of gas), and I frightfully merged creeping along to the shoulder narrowly missed being hit by several other trucks and vehicles. I went to lift the hood, expecting to be overwhelmed by heat and conditions that would cause a BMW to disable suddenly and lose power. I observed no conditions of heat or unusual to cause a shut down. I was able to turn car on again in 10 minutes with no problems the temperature was no different or warmer than I have ever felt before, conditions were 72/, traffic was moving along at a good flow, with light cool bay area breeze. This has occurred 3times now, I have filled the coolant, I have had the starter and battery replaced and yet the same occurrence comes up. ¿department of Consumer Affairs, ¿better business bureau, ¿us department of transportation, ¿national transportation and safety administration, ¿abc nightline reported: (abcnews.go.com/thelaw/BMW-admits-fuel-pump-flaw-turbo-cars/story?id=11968495 ), ¿dateline nbc reported: (www.nbcnews.com/business/BMW-recalls-134-000-luxury-sedans-over-tail-light-problem-4B11215107 ) ¿NY daily news filed a story : (www.nydailynews.com/news/money/BMW-recalls-150-000-cars-faulty-fuel-pumps-article-1.192673 ), ¿national highway tsa with safercar.gov.

Upon car system notification that a headlight malfunction was noted I open the headlight access door on the dynamic projection headlamp to inspect and replace the bulb. At this time I noticed large amounts exposed wiring going from the connector to the main harness. As I continued to inspect the wiring the insulating material around the wires continued to crumble exposing more wiring. This is true for both left and right headlights, both headlamps have sealed access doors and is concerning for.electrical short or fire hazards in/near the high heat generated from.the lamps and or engine compartment.

Battery died. Jumpstarted, drove for a bit. Turned off, turned back on drove home. Parked the car. Tried to restart and the red electronic steering wheel lock indicator was on. Plenty of juice in the battery, car will not even attempt to turn over. Can not get into neutral to tow out. Car is dead where it sits because of the electronic steering lock. Thank goodness we weren't in the middle of nowhere.

When parked listening to music, my brother plugged in the usb adapter and it electrocuted him ever since he's scared to be in the vehicle. Well right after the incident the cigar igniters to plug in the adapters wouldn't work anymore. I had just got this car from a dealer as a trade in 3 months ago and I noticed really strong smells of gas from the back seat and my siblings sit back there and that really concerns me. Along with the smell of gas, my coolant reservoir starting spilling out brownish fluid like if a gasket was blown and oil got into the coolant ! I am very irritated I'm being charged thousands that I don't have and only have had the car for a few months. My warranty would not fix any damages, and dealership is not helping me out. I need to go to work and school and I have no transportation at the moment.

First occurrence drivers side door will not open, door handle does not disengage lock mechanism to allow egress. Unlocking vehicile renders nothing as the door lock is interment and will not allow door to unlock either inside or outside of vehicle. Second occurrence roughly one year later, front passenger and drivers side rear door will not unlock displaying same chacteristics as first occurrence with drivers side door.

I was driving to work and the steering lock malfunction lite up out of nowhere. The car can not move. This is an electrical problem that's dangerous and expensive to fix. Very common problem expressed by many owners with the same model and year as my car. They should've conducted a recall on this!!

2007 BMW E92 335I - just took off from my home (car was not turned on since the day before atleast not after 8pm) 10 minutes into the road I turned on my A/C blower on max. On about 2 or 3 minutes, suddenly it slowed down and stopped working followed by plastic burning smell. As I tried to pull over as soon as possible, smoke started coming out the dashboard and just like that the car caught fire on the glove compartment and so on... I stranger from an tire shop ran up and used an extinguisher to stop the fire. Sadly there was severe damage to glove compartment, dashboard, electrical components like fuse box, passenger door, front and top interior.plus some money I had stored in the (was my way to the bank to make a deposit and pickup my fiancee) im still waiting for my insurance decision. Im very worried since I've search around in forums and I've read about some other people having same problems and other electrical fires with no response/resolution from BMW. I've owned a MINIcooper and 2 bmws. My cousins, aunt, granpa (E30) have bmws. Any suggestions?

Apparently, the electronic key is defective, leading to an engine shutdown. Fortunately, I was able to steer off the highway without power and restart the engine. Prior to the incident, the car would intermittently fail to start. I notified BMW customer relations after the incident. I was told that these keys have a non-replaceable rechargeable battery, that may "wear out", and therefore not hold a charge! they informed me that as my vehicle was out of warranty, they would not provide me with a replacement key unless I purchased a new one ($250), I pointed out that nowhere in the owner's manual is it stated that keys need replacement, nor the hazard of driving with a "worn out" key. The representative ([xxx], emp.#[xxx]) stated "there is nothing BMW can do in this case." Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I parked the car at work at 7:30 am. At noon a co-worker notified me that my car was filled with smoke in the cabin. I went outside and saw this and immediately called the fire department. I waited for them to show, and opened the door as smoke poured out from the cabin. The fire department said there was an active fire in the glovebox. It looks like it started around the blower motor for the ac and the fuse box. My insurance company declared the car a total loss.

The left passenger door lock has ceased to operate on my 2007 BMW 328I. It does not unlock with either the key fob or the main unlock switch. This is very dangerous if there were any kind of emergency involving this door needing to be opened.

Left headlight control module unit for xenon bulb stopped working on 2007 BMW 335I which caused the low beam xenon headlight bulb to go out at night. Many other BMW owners are reporting the same problem on the same side (left). Type in BMW 335I headlight control module and someone posting that their left side went out, is the first hit on google and many other posts I have seen also state the left side control module failed and their left headlight went out. It is a safety issue and a consumer protection issue as the cost to replace is $1100+.
