In the morning of October 23rd, I've noticed the low tire pressure warning indicator (tpm) turn on in my car for the rear passenger wheel. It appeared to be completely flat. With the runt flat tire, I drove carefully to the nearest gas station to fill the tire with air to specification of 42 psi. Hours later, I check the pressure to see if it holds. The tire lost significant pressure and the tpm turned on again. I once again went to the nearest gas station to fill the tire with air and hours later, it lost pressure again, eventually going completely flat. It appears that many other owners of this particular make and model with the same rim style is experiencing the same problem and I suspect that the rim has a slight crack driving under normal conditions. It seems to be a flaw in the structural integrity of the rim that allows it to crack and lose air pressure.

26sep12 the tire pressure monitoring system will provide a false failure when there is certain electrical interference (e.g. cell towers). This is a recognized fact as noted in the driver's manual (P.71). The issue is that the system fails to reset after the interference has passed and all of the failure lights remain on for an indeterminate period of time (from 2 hours to 3 days) before automatically resetting. Absent this resetting the car is unsafe as, without a warning system for tire failure (either low pressure or tread failure), an accident could occur. The dealer offered no solution as the computer does not register a system incident and all systems passed a computer check on 16aug.. BMW North America ([xxx]) could not provide any further assistance. A properly functioning reset system is needed to insure safe operation of the motor vehicle. Thank you for your time.
