We have been the original owners of our 2005 MDX. on December 12/18/21 at 630. We were wearing our seat belts. We were driving in clear weather on a new street at 35 miles an hour. The passenger side seat airbag and the right side curtain deployed. My wife was sitting in the front passenger seat. There was no collision or hazard. The Airbag just exploded. We were not hit by any metal objects. The Mdx is in perfect working order and we are now told no one will cover the damage. Insurance and the Dealership. We are writing to find out how we can get a fair outcome from our car becoming unusable due to manufactures defect. We have not touched the airbag or the car since this happened. Would we be able to have it inspected?

12/20/2009 58,000 mi ODI #10296492.0

Beginning in 2006 I started to experience a hesitation and a hissing sound in my 2005 Acura mdx at hwy and local rd speed for the past three years I have taken the vehicle to the dealership only to get the same response of unable to duplicate. I recently took the vehicle to the dealership again on 11/09 and this time they were able to duplicate the problem which was a bad torque converter which required the replacement of the transmission. The dealer claimed the issue started at 58,000 mile and therefore out of warranty. The dealer wants $4000.00 to replace transmission. Still contemplating offer. I have discovered blogs that states an ongoing torque converter and transmission problem with the Acura mdx from 2001--2005 including a recall for 2001-2002. *tr

Tl* the contact owns a 2005 Acura mdx. The contact stated that while driving she heard an abnormal grinding noise.

The dealer advised that the letter was sent to caution owners about the possible failures and that the computer would be updated to prevent the failure. The dealer advised that because the contact had already experienced the failure, they were unable to assist. The vehicle was not repaired. The failure and current mileage were 80,000.

Car is making a grinding noise at approximately 30 to 40 m/h. I had the timing belt changed and was told this noise is a transmission problem that is common to Acura mdxs between 02s to 06s. I have justified the cost of acuras because of their longevity and am very upset over the repair cost of $4000. Why hasn't Acura been forced to stand behind this defect when it seems to be so common when I investigated on the internet. *tr

I have a 2005 Acura mdx and felt the car noisy while driving after a while the vsa light came on and stayed on. Thank god I purchased an extended warranty because this happened 1 month after the manufacturers warranty expire. They had to replace the transmission at a cost of $3900. *tr

Engine mounts on the Acura mdx from 2003-2006 seem to fail regularly resulting in excessive torque on the transmission and potential steering input shimming. Honda/Acura is well aware of the early failure of these mounts per referencing tsb 06-014. Further evidenced by numerous inputs of multiple mount failure within a year. This is a significant defect that Honda/Acura should address with either enhanced design or warranty.

12/21/2005 ODI #10145841.0

I first noticed the issue when driving in stop and go traffic. Everytime I started from a stop or hit the brakes to stop there was a thudding noise or bang sound. I took it to the dealer to check it out and they say it is a know issue with this vehicle because of the way they had to situate the gas tank to accommodate the third row seats. It happens when the gas tank is not completely full and the fuel moves in the tank and make s the tank expand and causes the noise. There is nothing they can do about it. I called the manufacturer, they said same thing, they know about it but not going to do anything about it. *nm
