“While driving on the highway, my 2011 Bmw 335ci experienced a total power failure leaving me with very sluggish steering, no fuel power, and essentially a dead rolling heavy piece of metal.”
NHTSA complaint #10692004, filed 2015-03, 40,000 miles“My 2011 Bmw 335i, when driving at low speeds (>20mph) and turning (onto streets and into parking lots) stalls and loses all engine power. I am able to re-start car but the sudden loss of power cause safety issues because cars behind you may hit you. This has happened 7-10 times since 2012. I have taken in the car to kelly Bmw and mag Bmw in columbus ohio for inspection on at least 2 occasions, but due to Bmw's warranty requirements regarding replication at the service center, these intermittent but serious safety issues have not been addressed. …”
NHTSA complaint #11032918, filed 2017-10, 12,000 miles“I have had an incident with my car where my car died whiling going on to my military base. After finding out the issue and getting it worked on, I found out that there is a known issue. There are several public complaints of users risking their lives due to a documented defect with n55 engines produced from 2/2010 to 12/2010. This engine is used in several Bmw models, mine included. Both (intake and/or exhaust) of the vanos gear assemblies have failed; the attaching bolts may have also loosened and/or broken. …”
NHTSA complaint #10574484, filed 2014-03, 83,000 miles“Vehicle intermittently stalls at low RPM (less than 650) and low speed (less than 10mph) while driving. Stall happens in every 300-500 miles and car looses power (steering wheel and other power) while on stall making it dangerous to drive. Car doesn't through any fault code to the system if stalls. Mountain view, ca Bmw dealer's technician couldn't reproduce the stall as it happens intermittently and service agent suggested me to keep driving till it gets frequent so that they can reproduce at the dealership. I'm scared to drive the car as it can be a huge risk as it loses power while stalls.”
NHTSA complaint #10881910, filed 2016-06, 47,400 miles“My 2011 335i Bmw convertible stalled for 2nd time while less than 200 miles driven in between. Vehicle stalled in slow speed while turning left in both cases. Vehicle lost total power in both cases. Took to the Bmw mountain view, ca dealership in first occurrence. Dealer checked and no fault found in the system. Technician drove ~60 miles and couldn't reproduce the issue. Dangerous to drive the car as it stalls. Vehicle has only ~38k miles on it.”
