SUBJECT: Recall Campaign 14V‑176: N51, N52K and N52T Engine – Replace VANOS Gear Bolts, (This Service Information bulletin supersedes SI B11 07 14 dated September 2014). My 2011 BMW 528i has around 279000KM and Vanos Gear bolts are broken that Could Lead to Engine Stall and although the federal safety agency has issued recall campaign but BMW dealers are refusing the repair by saying that no such recall is showing against my vin [XXX]. As per online research this is a known issue in my car model and the federal safety agency has already issued a recall campaign#14V‑176 as showing at the top of this statement. I had this issue with VANOS for almost 3 yrs as car was throwing error message once in a while and engine hesitates and bogs at lower RPM. Rough idling/ increase in engine misfires, Increase in fuel consumption. I changed several parts to troubleshoot but could not figure out the actual root cause of this problem, until recently an independent shop opened the engine to change the Engine valve cover/PCV valve, when they noticed that 2 VANOS Gear bolts are broken. That mechanic advised me to contact BMW immediately and stop driving the car as this can lead to permanent serious damage to my engine and car will stall immediately that may cause an accident or a crash. I have always taken good care of this car and hoping BMW to cover the parts/labor cost under recall campaign. I would really appreciate your help is getting this matter resolved with BMW Canada.

There is hesitation or delay with this vehicle upon initial acceleration and when it finally does accelerate it almost gives you whip lash. This is dangerous because you are at intersection and unable to proceed through it initially and then you accelerate at a significant rate. It is so frustrating. And I do not feel safe driving this car. I hope I do not get a neck injury from taking off so suddenly and I pray that when I do accelerate, it is not into the vehicle in front of me.

This vehicle has a hesitation of throttle acceleration from idle and shifting between gears.presents a real safety issue from idle position to acceleration. A 1-2 second delay consistently happens. The bmw dealer reported to me that they are aware of this situation but do not have a solution yet. If enough reports of this incident were handed in then it may necessitate a cure from bmw. Apparently not enough squeaky wheels per say for bmw to act.hopefully this along with hundreds of these complaints already on your web site about this very same issue is enough to get bmw to act on this safety issue.

From a complete stop, when accelerating, there is a lag or hesitation before the car takes off. When it does take off, there is a hard jerk. It makes it very hard to gauge the distance between you and other cars when it lunges very quickly. If you're pulling into traffic, as in my case, it can be very dangerous. Also if it's wet, and this happens, it could cause you to lose control of your vehicle. This needs to be investigated, as it can be a major safety issue.
