As I was slowing down to make a turn, the vehicle went into neutral and shut off. I immediately turned it back on and put it in drive and the same thing occurred moments later. I start it again and drove away enough to safely park. I let the car rest in the off position for 30 minutes and it drove fine. There were no warning lights and the vehicle is well maintained with scheduled services. I contacted the nearest reputable mechanic and explained the situation. I drove it there. They found no faulty codes when they plugged in the computer and the battery has no issues. The vehicle drives fine now, but this is very concerning especially since this took place in local traffic.

Vehicle indicated the engine was operating at reduced power, unable to accelerate and barely able to pull over. Speed was reduced to 5mph in the middle of the highway.

The car is putting out white smoke. It seems as though oil is entering the combustion chamber and burning out of the exhaust. The oil is either burning or leaking into the fuel system. There is a significant decrease in fuel consumption and the acceleration is affected. As I was driving there was a warning that the engine has gotten too hot to drive and to pull over immediately and I had it towed to a garage. There were no temperature warning lights or coolant warning lights and coolant level was fine. BMW does not have a temperature gauge to know if your car is getting hot. Stupid design.

X5 xdrive 35I sav; while driving under normal street and highway conditions, vehicle speed and engine RPM have become unstable. This causes the vehicle to increase and decrease it's speed intermittently and without warning. The vehicle is not trustworthy as you may lose power, or unintentionally accelerate while trying to execute a driving maneuver, causing a dangerous condition. Check engine warning light illuminates. Vehicle was brought to BMW dealership (zt motors) for diagnostics. Service personnel stated that the high pressure fuel pump indicated a low fuel pressure at the inlet. This would tell me that the low pressure fuel pump is not delivering the correct fuel flow/pressure to the high pressure fuel pump. Ref NHTSA campaign # 16V746000 et al. Diagnostics also indicated the valvetronic motor shows it short circuiting. Dealer recommended replacement of valvetronic motor, cam shaft and oil injectors. The replacement of the cam shaft and oil injectors are unnecessary maintenance items, only the valvetronic motor would need to be replaced, and fuel system reprogrammed. Ref NHTSA campaign # 14V176000 et al. Recommend recall replacement of both high pressure and low pressure fuel pumps, valvetronic motor, vanos cam shaft and oil injectors as well as reprogramming of fuel operating system. Also replace cam shaft mounting bolts.

On Saturday May 6th 2017. I was driving when I heard this noise to my untrained ear it seemed as if the noise was coming from my front tires? I pulled over got out to check my front tires/wheel's and there was nothing, I get back into my vehicle and start driving again after a few minutes the same noise could be heard again so once again I pulled over got out and checked my tires/wheels and undercarriage. As I am looking there is nothing hanging or loose, I get back into the vehicle and started to head towards my house I was only about 6 blocks away from home so I call my fiance and asked he to come outside (I wanted her to drive the vehicle just a little so that I could see if my wheels were doing anything strange, this would help me to better explain what I through was happing to my vehicles wheels/tires) as soon as I hang the phone up I slowed down to go over a speed hump at the time I did not notice but I had lost power in the vehicle as I tried to use my breaks the vehicle did nothing and I do mean nothing so now I am rolling straight and go through two stop signs hoping and praying that one hits me, due to the vehicle having no power. A message shows up on the screen saying 'transmission malfunction' the malfunction maybe resolved by restarting. Contract nearest BMW center if necessary. Use emerg. Release to disengage park detention prior to towing or pushing vehicle. Now mine you this message only showed after the vehicle lost all power. As I am going through the second stop sign there is a slightl/small hill that I went up and the vehicle lost enough speed that I was able to smash the brakes real hard to stop the vehicle from moving. A car all most hit me in the rest because of this action, and now I am sitting on this slight hill holding my foot on the break. Once the vehicle was towed to a BMW dealership I was told about the driveshaft recall.

Severe acceleration delay from a stop pulling out into traffic nearly caused me to be broadsided. During the first 1/2 to 1 second after depressing the accelerator there is little to no reaction from the vehicle. After this pause, which is well beyond what could cause an accident, the vehicle surges uncontrollably. I found myself sideways on a wet paved road. My natural inclination after the pause was to press for more gas, any other reaction would have left me sitting in the middle of oncoming traffic. This complaint is well documented when researching BMW acceleration lag or throttle tip in on the internet. It is incredible that BMW would be able to allow such unsafe programing of their vehicles. This is sure to have caused accidents. I was lucky, others may not be.

In March of this year my X5 had the increased engine noise, check engine light coming on, and stalled on I-80 in omaha. I got the car pulled over and started again. I then had husker auto of Lincoln ne (BMW shop) look at it. This has not happened again to date. In June I get a letter from BMW about the safety recall of vanos assembly bolts. The description of the problem fit my situation back in March. I took the letter to husker auto but they said I had to wait for another letter from BMW. I have approached husker auto twice more since June, with same story from them. My question to you, is there anything your administration can do about BMW not acting timely on the X5 recall issue?

My 2011 X5 35I has an acceleration delay. BMW has recognized it as an issue in the 535I models, calling it an "acceleration delay" and have issued an sib software update to repair it, but have not done so for the X5 model. I feel this issue is dangerous and a safety issue.

2012 BMW X5. Upon engine start up when cold, the engine surges excessively. If the transmission is engaged during the surging (fluctuating RPM) the vehicle lurches forward/reverse causing a dangerous situation and potential accident.
