While driving the SUV in a busy street 30-45mph felt the vibration, grinding, the triangle distress sign came on and felt the vehicle is going to stall. Managed to get the SUV to the parking lot on the right side. The SUV completely stalled there and we got it towed to the acura dealer. They looked at it and the technician gave us the initial diagnosis as "radiator has blown coolant line , fluids have cross contaminated and will take a lot of time to bleed out, also possible transmission failure in the process would need to retest drive after radiator replacement to see if transmission works".

I have code p0740 which is tcc function. My trans is operating erratically and undriveable. After faithful service intervals the trans died in my car. Acura denies knowledge of the problem even though there are thousands of people their torque converter failed due to a design flaw. I was almost killed when the trans shuddered and stalled in the middle of the road. I am furious this car is expensive and no need for transmission failure at such low mileage. Please recall and help.

2005 mdx. Within one year of purchase, a high pitched ringing was identified to the acura dealer. Sound was dismissed as normal. For the next four years the sound recurred on acceleration and uphill driving. At 64,000 miles the ringing sound was diagnosed by the dealer to be a failing torque converter. Torque converter was replaced by the dealer (warranty). One year later, the transmission began making a rumbling sound while accelerating between twenty and thirty five miles/hour. Also, the ringing noise re-emerged. Car was taken to dealer. Dealer informed us that there is a recall on our mdx regarding the rumbling problem--told it is an electronic problem requiring a one hour fix. (though at this time I can find no information about this supposed recall). The mdx was given to dealer for fix. After the first day, dealer informed us that the fix had not solved the problem, and they would try again (at the direction of acura technical support) the next day. Again, the dealer informed us that the problem was not fixed. Dealer's mechanic has told us it is the transmission that is faulty, but unfortunately acura technical support is refusing that diagnosis. The car is now going on its fourth day in the dealership and we have been told by the service adviser that acura is unwilling to address the problem beyond the electronic adjustment. We have been advised by them to drive the car until the problem gets worse, then bring it back. The problem, prior to dropping the car off at the dealer this last time, occurred almost constantly while accelerating slowly between 20 and 30 MPH, at times feeling as if the car may stall. It has yet to pose a safety hazard, but has completely eroded our confidence in the vehicle's ability to take extended trips. Fear of breakdown keeps our trips limited to twenty miles or less. We have spoken to a lawyer and will file lawsuit if acura does not address this obvious and unacceptable flaw.

Dt*: the contact stated while driving 20mph the airbag light illuminated without warning and the engine stalled. The engine would not restart and the battery was discharged. Afterwards, the airbag and tire mounting light illuminated. The vehicle was seen by the dealer and the battery was replaced. The dealer determined the navigation unit was draining the battery. The engine stalling persisted and the vehicle lost all power. The engine was restarted but continued to stall. The vehicle was towed to the dealer who determined there was a short within the airbag SRS module wiring. Although the airbag problem was corrected, the stalling continued. The vehicle was taken to the dealer for further inspection, but the dealer was unable to duplicate the stalling problem.
