2009 BMW M3 Owner Comments

problem #3

Oct 172016


  • 44,300 miles


The car suddenly vibrated and the wheels locked up and skidded slightly sideways before going into a reduced power mode. If it had been raining or snowing, or at a higher speed on highway the situation could have been deadly. I had the car taken to the dealer. I was told a the throttle actuator valve was defective. The car has only 44K miles but has surpassed the 4 years of warranty. This is a known issue with thousands of cars affected. BMW refuses to recall and repair the item if the car is not under warranty. The cost for repair is $3000 the part alone is $1200 which I was quoted. My vehicle is also affected by the takata airbag recall.

S65 V8 engine in a BMW M3 E90/92/93 and M5's with a V10 has two throttle valve actuators that fail prematurely at 40-80K miles. Both the internal nylon gears and electronics will fail, affecting accelerator pedal response and causing hesitation, especially with the dct transmission. These parts are not a maintenance item. When failed, the engine malfunction, excess emissions, skid control, and ABS braking warning lights are triggered. Engine goes into limp mode. This is dangerous when it happens while driving in rainy, snowy, and icy road conditions. The throttle valve actuator design defect should have triggered a BMW recall. Replacement parts are $1000-1300 each plus $1000 labor and have never been redesigned by BMW/Bosch. So the replacement parts are also defective and will fail prematurely. Repairs occurred on Dec. 2012 at 80K miles for $2000 and on Jan. 2016 at 140K miles for $3000. A BMW M3 and M5 recall and redesigned parts are warranted. BMW technical service bulletins should be issued for this design flaw. 8yr/80km federal emissions warranty should cover these repairs as well.

Vehicle lost power while taking a turn. I was able to restart it and drive to a nearby parking lot. I drove around slowly to test and noticed knocking noise from the engine. I also noticed engine temperature was above normal, not quite to the next marker, but close. At that point, I had the car towed to a BMW service shop. Their diagnosis was rod bearing failure which led to crankshaft damage, resulting in an engine, with only 57K mi, that is no longer reusable. I am now facing engine replacement costs of $15-25K.
