Owner reports
Selected complaints filed with NHTSA by 2007 BMW 335i owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2007 BMW 335I. The contact stated that while driving at 50 MPH, the vehicle stalled with the yellow check engine warning light displayed on the instrument panel. Due to the failure, the vehicle behind him came to a screeching halt to avoid causing a major accident. Multiple attempts to restart the vehicle failed, resulting in the vehicle being towed to an independent mechanic. The mechanic determined the failure to be a defective high-pressure fuel pump. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 177,000.
I bought a 2007 BMW 335i convertible on March 10th 2022. On March 18th I left my house and as I was pulling out of my neighborhood the vehicle cut off at about 25 miles an hour and as I pulled over I noticed black smoke coming out from under the hood. There were no warning lights on with the exception of a random airbag light that came on the day after I bought the car and a tire pressure monitor light. My wife and I pulled over and I ran to a nearby house and took a case of Dasani water from painters who were working (with their permission). I got the fire put out within minutes of its starting but the wiring harness is completely melted together along with all of the induction piping to the turbos and the intake manifold and fuel line. I told the car home and had my insurance agent look at it. …
The oil filter housing gasket, the mechatronic transmission and the electrical system failed. Yes, it is available for inspection. My safety and the safety of others were put at risk as a result of my vehicle losing power suddenly while I was driving on the highway. I was driving at the highway speed limit and my vehicle malfunctioned and lost power while others were at high speeds. I had to abruptly stop almost causing an accident. The problem has been reproduced and confirmed by the BMW service center. The vehicle has been inspected by the BMW dealer service department. The warning lamps that came on my dashboard were the check engine light, oil level light, and the transmission light. The car was running poorly. The engine wouldn't crank and then it would jolt after driving. I would smell oil occasionally. The symptoms first appeared in 2011. …
There is already a recall for the fuel injectors in vehicles like mine but my VIN number is not apart of the recall. I am having the same issues stated in the recall. Recall sib 13 01 20 which is for vehicles like mine manufactured between 04/07 and 11/08. My vehicle was manufactured in 07/07 but somehow it was not included. I have been troubleshooting an issue with the vehicle hesitating and misfiring and it is due to the fuel injectors leaking into the cylinder. I have replaced all spark plugs and ignition coils and there is evidence that the spark plugs have fuel on them due to the leaking fuel injector. When I start the vehicle it starts normally but after idling for 5 minutes it begins to misfire with white plumes of smoke exiting the exhaust. The vehicle was not driven before or warmed up before this happened. …
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. …
There is a serious defect with the engine and fuel pump. It takes a long time to accelerate when driving especially on the highway, the car will shake, jolt and the engine will start to make a weird noise. There is oil leaking constantly and the check engine light is constantly coming on even after just being repaired. The car goes into limp mode and has shut down on me numerous times while driving. I've had the fuel pump replaced numerous times and yet it needs to be replaced against. The car will overheat at times and and just shut down. I was driving on a busy city street when the car just shut down, I couldn't steer or brake it just died in the middle of a busy street. It was extremely unsafe and put my life in danger as well as the other drivers on the road, especially since they were driving at fast speeds.
Tl* the contact owns a 2007 BMW 335i. The contact stated that the engine warning indicator illuminated and the vehicle began to shudder as if it were going to stall when the accelerator pedal was depressed. The contact took the vehicle to checkered flag BMW (5225 virginia beach blvd, virginia beach, va 23462; [phone] or [phone]) where it was diagnosed that the high pressure fuel pump and the low pressure fuel sensor failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that the vehicle was included in the voluntary recall regarding the failure; however, due to the age of the vehicle, the failure was no longer covered under warranty. The approximate failure mileage was 73,000.
The car has had numerous issues since purchased. This all came to a head when driving home, under normal conditions, it suddenly would not shift past 1st gear. I proceeded to pull off to a side street and attempt to idle home, as I was about 1 mile from home. After approximately .5 mile, the transmission suddenly lost first gear, there was an audible bang under the hood, and the car completely lost power. After being in a service center for a couple weeks, I am now informed that the engine is locked down and that the car will require a new engine to be working again. This car had been an absolute nightmare and has turned me quite calloused towards bmws quality standards.
High pressure fuel pump - critical failure while driving in heavy traffic on the highway, the engine died without warning while in motion. Brakes and steering became incredibly heavy (presumably without power) as I pulled over with very little time to react. Car would not restart, just repeatedly turn over without trying to start. Pulled codes to discover that the high pressure fuel pump just failed completely - p142e $0018pd. Stalling in motion without any warning signs was scary. Turbo wastegates - caution turbos rattle severely while driving and performance is reduced. Extra time and space is needed when merging and overtaking. No engine codes.
All 6 fuel injectors were leaking and caused the car to stall on the freeway. The fuel injectors were replaced along with the spark plugs and coils. 1 year later at 100K miles, the same issue has arisen. The fuel system seems to be a constant problem with this car. It is a very dangerous problem, since the car shuts down at high speeds on the freeway. BMW should extend the warranty on the fuel injectors as they did with the high pressure fuel pump.

Engine stalling - fuel pump failure
In response to odi's information request for pe08-032 BMW stated that during failure of the high pressure pump the customer should initially experience longer engine starting times or rough engine running.after a distance of approximately 1 to 2 miles the pump- and engine-emergency operation program is activated, and the malfunction indicator lamp is illuminated.despite reduced engine power BMW believes that safe…
