POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)
EVENT_SUMMARY
Your vehicle's transmission control module, which helps the automatic transmission work properly, might have a problem with its cover. The cover might not have been made correctly, which could cause oil to leak into the module.
RISK_ASSESSMENT
If oil leaks into the control unit, it can cause the transmission gears to seize, leading to a sudden loss of power and potentially increasing the risk of a crash.
RESOLUTION_PROTOCOL
You can have the transmission mechatronics module and fluid replaced for free at a dealership. You'll receive a letter with instructions, but you can also contact BMW customer service at 1-800-525-7417 for more information.
