BMW 335I jerking problems

Filed Dec 30, 2022 · Engine · NY

I have an F30 body style bmw with the N55 engine. After purchasing the car I noticed a very rough idle for a few moments when warming up the car. The idle would be so rough that when in gear to reverse out of my driveway, it would jerk the car further than it should be meant to go. A slight tap of the throttle and the jerking would propel the car forward resulting in a dangerous situation. I almost collided with a couple of cars so far and I have kids in the car. Upon much research and performing car diagnostics, it was found that the cars valvetronic system which controls the idle for fuel efficiency is defective. After looking into this further and joining a few online forum groups with the same vehicle, it has been known that this is a vastly common issue with this vehicle. Thousands of owners had come up with top issues with this engine and this issue is at the top of the list. I do think that bmw should be responsible for this system as it fails very early on. I only have 58,000 miles on my vehicle and thousands of others reported the same issue and low mileage. This system needs to be looked at for safety precautions.

So I got a paper saying I had a recall on my air bags so I called and got my car takin to bmw in bellevue. Bmw's road side assistants gave the wrong address to the tow company and would not answer the phone tow for them> I even attempted to call and was placed on hold for approximatyely 40 minutes to fix this problem. Finally I spoke with the tow companys dispatcher who was so frustrated he started accusing me of playing games and threatened to have my vehicle dropped at the wrong dealership then extorted me for another 80 dollars just to drop my car off his truck and leave it at my house. Hours later after finally getting a hod of roadside assistance the exact same company returned and delivered my vehicle to the right location. After all of this we are being jerked around by bellevue bmw on the recalls they asked me for 3 hours of labor and promised us to get the vehicle started after approximately a week they said my dme is bad an it would cost 8000.00 to fix it and said it wasn't worth fixing because it was old never mentioned anything about a recall until I finally brought it up the last time I spoke with bmw in bellevue which was monday the15th of march 2021. I was told the wire harness was repaired not replaced and the airbag recall was replaced. Then said my bill was over 600.00 > after doing my research thru theagency website I found out my recalls were not fixed and I took photos with the dates and time showing my recalls were not fixed which I feel upset and very worried and concerned for my safety now I am not sure where to go from hear because my family and I are being placed into a hardship and to make it worse we are in the middle of a pandemic please help us. I don't know if anything was done to the car I think we need to talk to an attorney

"limp mode" is a very well known issue affecting 2012-2014 bmw 335i models with the m sport package. After accelerating from a stop to 60-65 MPH, and merging into traffic, I experienced limp mode. The car would not accelerate, the rpms would not rise above 2500 or fall below 2000. The oil temperature was approximately 200 degrees. During the sudden loss of acceleration and power, no matter how hard or far I pushed the accelerator, the car would not accelerate- the car completely lost all power and the ability to accelerate. As I was coasting, I tried pumping the gas and shifting gears (shiftable automatic) to no avail. There were no warning lights on the dashboard or other warning messages displayed. While traffic zoomed past me, I coasted for a good 30-60 seconds gradually slowing to about 15 MPH. After roughly 60 seconds, I pushed the accelerator down again and the car bucked, lurched and jumped and the rpms began to rise. I was able to accelerate normally again though the temperature did rise to roughly 240. I made an appointment immediately to have the car checked by my local bmw dealer. They replaced the aux cooling fan and applied a software update as is the case with "limp mode". This is the same "fix" applied to countless other 335i owners which simply doesn't work. My dealer opened a puma case with bmw to resolve the issue. Standard operating procedure is to replace the fan and apply a software update the first time, replace the fan relay the second time and apply a software update the third time. None of these work!! Check f30 post, bimmer world and bimmer fest forums. Dealer was great, but I wanted them I will fight for a buyback if it happens again. Had this happened a few seconds later, while pulling out in front of cars traveling 65+ MPH, I would not be here now. Recall this piece of crap!! When my lease is up or if I can get out of it, I will. Not safe.

I am very happy to see your organization taking an interest in this issue. This is a dangerous problem with this vehicle that bmwna is well aware of, but insists that it is "normal behavior" for my car/transmission. I brought the car into the dealer, and they were able to reproduce it, but they were told by bmw that this was "normal behavior." the problem occurs when you slow down- like for a turn, but do not come to a complete stop. The dct transmission seems to have trouble figuring out what gear to select because when you step on the gas to accelerate, there is a very significant delay in the onset of power- up to 2-3 seconds. By this time, the driver is usually really digging into the throttle. The transmission finally picks a gear, which results in the car suddenly lurching forward, sometimes invoking the anti-skip control. The danger in this behavior occurs when making a turn into on-coming traffic after slowing down to around 10-15 MPH. After the turn, the car is positioned in the traffic lane, but you have no power to accelerate into the flow of traffic. The oncoming cars are now closing in on your car at a fast rate, and you're basically stuck. This situation is most pronounced in the "auto" mode of the dct transmission, but also occurs to a lesser degree while in the manual mode when you select second gear in preparation for the turn. It is also very repeatable in both modes. These problems started occurring after a previous recall on this transmission where the engine would stall under hard braking or not shift under hard braking. The recall fixed that problem, but introduced this problem, which occurs almost every day whereas the previous problem only occurred during a specific situation. Thank you for looking into matter.

Tl* the contact owns a 2010 bmw 335i. The contact stated that while driving at speeds between 5 and 25 MPH, the vehicle hesitated to accelerate and jerked when the accelerator pedal was applied. The vehicle was taken into an authorized dealer and they stated that the fuel pump needed to be replaced. The vehicle was repaired, but the contact noticed that the vehicle was still experiencing the same failure. The vehicle was not repaired correctly. The failure mileage unknown and the current mileage was 13,000.

I would formally like to report a major safety concern I have regarding my new 2011 bmw 335is convertible. From a standstill without modifying any of the default configurations on the car, flooring the gas pedal, the car lurches forward (as expected) and then power completely cuts out for a second and then will continue on its way. My guess is the dsc is kicking in causing power to be reduced and then re-established. My concern is that a brand new car should be able to be floored without this happening. I recently had this exact situation occur as I was pulling out into traffic and very narrowly missed getting pummeled by another car when power was cut to my car. I have taken my car to my bmw service station and although they agree that the car should not do this?they at the same time say the car is operating normally. Their advice was to turn off dsc in a situation I want to floor it. This is my 3rd bmw 3 series convertible and I have never experienced this. Also, I do not think the driver should be forced to consider this before pulling out in traffic. And, if I were to lend my car to a family member, how would they know.

Long cranks, stuttering upon pushing on the accelerator with lurching sensation and front engine block shaking. It used to occur every day before they replaced my first high pressure fuel pump at 2500 miles. Second time I had long cranks a few times a week with lurching/stuttering sensation upon pushing on the accelerator while hi-way driving every day. I have a 2009 bmw 335i . Vin [xxx]. I've had my hpfp replaced once. The second time around they just reprogrammed the hpfp but I still get long cranks 2 a week with lurching/stuttering on hi-way acceleration attempts.

Bmw 335i 6-sp manual began shaking roughly on start-up, rpms jumped up and down wildly between 500 and 2000 and check engine light came on. Turned off car, restarted, idling settled down, car ran fine, check engine light did not come back on. Same problem on next startup, but check engine light did not come on and I did not turn off car. After about one minute of idling, car began idling normally, drove fine. Same problem on next start up--called dealer for service. Started car, it seemed fine, so I drove away. On the way to the dealer, the check engine light came on and the car began shaking roughly while driving and had severely diminished acceleration power. Downshifting did not help. Could barely get up to highway speed, especially climbing a hill. Took it to the dealer. Hpfp was replaced within 2 days. Seems okay, but occasional lurching, perceived lag in acceleration at low speeds, and knowledge that this is a known problem with bmw x35s makes me question the car's reliability.

When starting my car the engine jerked and almost stalled on start-up. Also under normal driving conditions car acceleration is sluggish and is "jerky" during braking. This has been a recurring problem since I took delivery in october 2007. Fuel pump and fuel injectors have been replaced twice. Car is in the shop on average of once every 3 weeks! Dealer continues to replace parts but the same problem occurs. Parts seem to be defective!
