The vehicle was in motion when I heard a loud pooping sound. A diagnosis was done at pep boys, raleigh nc and I was told the number one spark plug exploded and therefore messed up the coil. I was turning on a city street.

The contact owns a 2006 Acura MDX. While attempting to park in a residential garage, an abnormal noise emitted from the engine. The brakes were engaged and the vehicle suddenly accelerated and crashed into the garage door. The vehicle then accelerated independently in reverse, made a turn, and crashed into a parked vehicle before stopping in a neighbor's front yard. The front driver side curtain air bag deployed. The contact mentioned that the vehicle spun around approximately four times in the middle of the street before coming to a complete stop. A police report was filed. The contact and passenger sustained minor injuries and both required medical attention. The vehicle was towed to an independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 101,000....updated 09/28/15

Like others with the 06 MDX I had to have the motor mounts replaced. It is very possible the "judder" as Honda calls them from the torque converter caused this even though I had the computer software fix. This became an issue as the vibrations from the bad motor mounts damaged the front right half shaft/axial and I was told I was very lucky it did not break while I was driving on the highway.

Transmission has problem shifting and down shifts without notice even when applying pressure on gas - causing car to slow. Dangerous for cars following behind - almost rear ended.

On January 14, 2014 my daughter took our 2006 MDX to the dealer for mechanical evaluation. The car has been hesitating while driving, trying to stop the car while driving. The diagnose came back with the following: Transmission needs to be replaced and engine mounts have to be replaced as well for the total of around $7,200. In October 2008 (mileage 55K) the original transmission has been replaced with a re-manufactured part. December 2009 original symptoms (whining noise, shutter at 40-50 mph) have recurred and have been reported to dealer's mechanics. They could not see any problems. December 2010 whining noise started coming back again. Dealer's mechanics could not find anything wrong. Now we are faced with a transmission that is malfunctioning plus engine mounts have to be replaced. In speaking with Acura's customer care I was informed that the transmission replaced in 2008 was not an authentic Acura part. I kept insisting on more in depth explanation but did not receive any. It is my understanding that improperly working transmission causes damage to engine mounts. It seems Acura dealer's mechanics have somewhathow missed it. Acura is not willing to take responsibility for any of their omissions. Now the car is no longer under warranty. All of described instances are a huge safety hazard. Putting in non-authentic parts under the label of warranty is a fraudulent step. All services have been performed at jerry damson Honda dealership in huntsville, Alabama. I would like a formal investigation. In addition I feel that dealership's mechanics should go through additional training to avoid future misdiagnoses and a reduce danger to consumers.
