I, along with my wife, pulled out of the parking slot with seat belts securely fastened and started driving. After a few seconds the car went into sudden acceleration. I had no control on brakes or accelerator. I had to find a way to stop the car. I steer the car on to middle curb of the parking lot. First I hit the gate, which was flexible and did not stop the car. Next thing I hit was a light pole. The car stopped with both air bags deployed, lot of damage to car (completely totaled) and causing personal injury to me and my wife who was in the passenger seat. Due to the speed of the car, the concrete base was lifted from the ground and the pole fell in front away from the car. We both checked into the hospital immediately after the crash. This was caused by manufacturing defect in the car. The reason I say this is because: A) I just left the prayer hall, where I go frequently and am familiar with the surrounding where other cars are parked and moving, people are walking to and from their cars, and had no reason to accelerate; B) I have been driving accident free for past 39 years, my driving record speaks for itself; C) driving is required in the profession I am in, where I have to visit clients few times a week; D) I am familiar with the car because I have been driving this car for over 4 years. E) I am a family man and not a reckless driver. I care too much for my family, and especially my grandson, to take a chance like this; F) I am perfectly healthy and conscious about my surroundings. It has been six weeks and we are still experiencing pain from the injury. I believe something needs to be done to avoid such incidents in future. This crash could have been fatal.

The driver side front brake randomly applies even if you don't touch the brakes. It pulls into oncoming traffic. The vsa! light comes on every time signaling an issue with the traffic control. There was recall that was supposed to fix the issue however it did not. It can occur at 70 mph or 5 mph, there is no rhyme to why it occurs however I fear for my wife and my children when it is driven.

The contact owns a 2005 Acura MDX. The contact stated that while driving 55 mph, he heard a grinding noise and the vehicle pulled to the passenger's side and decelerated independently. The contact stated that the failure recurred the following day while driving 45 mph. After a third failure, the contact had the vehicle towed to the dealer. The contact stated that NHTSA campaign number: 13V092000 (service brakes, hydraulic, traction control system) was previously done on the vehicle. After the repairs were completed, the TPMS, vsa, and traction control lights illuminated then the failure recurred. The contact had the vehicle towed back to the dealer who revealed a yaw sensor code via the diagnostic test. The vehicle was repaired but the failure recurred. The failure mileage was not available.

2005 Acura MDX: Leaving my neighborhood I took a right turn onto the main thoroughfare. After some acceleration (1st gear), I heard a loud squeal/blow. Immediately had no power to maneuver forward and off to side of road in busy traffic. Ironically, MDX was taken for maintenance at dealership. MDX seemingly tested with flying colors 43 days earlier. No cautionary comments from mechanics at dealership.

Driving on city street 1 block from entering freeway I felt a strange grabbing and vibration type sensation from my 2005 MDX. A few feet further the car felt like I had stepped on brakes and gas at the same time and literally stopped in the middle of the street. The car behind swerved and barely missed me. I managed to get the vehicle to the side of the road and called Acura roadside assistance. Had I been on the freeway this would have caused a multiple car collision the roadside assistance was wonderful but I feel that since I only have 70,000 miles on this car; this should not have happened and the locking of the wheels at any speed is unacceptable. The repair was a replacement of the modulator assembly ABS/vsa at a cost of $$1653. I just keep wondering what would have happened had I been on the freeway driving 70 miles per hour.

My accident is still under investigation, but I am going to tell you about this so anyone who has an Acura MDX will be aware. On the day of my daughters wedding, I was in a terrible accident in a parking garage. There were 4 passengers in the car. My transmission surged as I was in reverse hitting a cement pole, within a second, the car surged forward hitting another cement pole. The airbags thankfully deployed. I was burned, badly bruised and have neck and back injuries as does the passenger in the front seat. This car was totally out of control. After researching on the internet I have found numerous complaints involving transmission problems with the Acura's. if I had been parked on the road, there would have been fatalities. I missed hours of the most special day of my daughters life. These memories were stolen from me. My car was at the dealer approximately 3-4 weeks prior to this accident. $700 for the car to be checked and ready to go! please do your homework if you are planning to purchase this car. I loved it too!

The contact owns a 2005 Acura MDX. While driving in reverse, the contact heard a clunking noise coming from the rear of the vehicle. The vehicle jerked backwards and struck a concrete pole approximately 2 feet away. The vehicle automatically shifted into drive, surged forward, and struck another concrete pole. Both air bags deployed. The passenger in the front of the vehicle was trapped and unable to open the door. The police, ambulance, and fire departments arrived at the scene. A police report was filed. The contact had burns and cuts on her arms and face and a swollen right knee. She will have to undergo therapy on her neck and knee. The passenger was badly bruised. The contact spoke with Acura on September 17, 2007 and they stated that their legal department would be in touch with her, however, they have not responded as of yet. This was the second time this failure has occurred. In the first incident, the vehicle was placed in drive and accelerated on its own. The failure occurred while driving 25 mph. The VIN, engine size, and current mileage were unknown. The failure mileage was 32,000. Updated 12/12/07
