2000 acura tl seems to have a design flaw that causes sub-frame corrosion. the probable cause is the a/c drain hose draining on top of the front passenger side of the sub-frame. the symptom was a 'clunk' (metal on metal type noise) when making a right-turn. i took the car to a local garage and they showed me that the passenger-side sub-frame has fallen apart due to the corrosion. i contacted acura customer care and referred to other complaints and a 2012 abc news report on this issue requesting a recall. but, they did not recognize this as a defect and failed to provide any assistance with resolving the problem since the vehicle was no longer covered under the manufacturer warranty. given the serious nature of this defect, it would seem appropriate that a recall or safety warning be issued to all owners of honda vehicles impacted by this design issue. *tr
Car family owned since new and serviced. the front right subframe (rear side of the two parts of the subframe cradle) rotted completely thru (passenger side) leaving hole thru and leaving control arms, steering rack detached. the rest of the frame is rot free, just this one area which is completely rotted away. a google search shows that this is not uncommon with this model acura tl and some honda accords. *tr
The front right side of the sub frame has excessive corrosion (rot) and needed to be replaced. i am the original owner and the car has been entirely dealer maintained and thoroughly inspected frequently. i discovered the corrosion while changing the front right tire. dealer informed me the car was unsafe to drive as the front right tire would eventually collapse or fall off. the problem was reported to acura and acura would not provide assistance due to the age of the vehicle. the car was repaired and i am in possession of the rotted sub-frame. other than the rotted sub-frame, the car does not exhibit any rust or corrosion. *tr
