On June 30th 2019 after leaving from work I was on my way to pier 1 which is approximately 2 miles away. I turned into the parking lot parked in front of pier 1 and all of a sudden my car accelerated out of control. It jumped the curb crashed through pier 1 window into the store and didn't stop until it hit a wall. At this time I'm in shock glass is every where and I could move I hear people in the background telling me to get out of the car but I was frozen from what just happened. I just want to hold Acura accountable because I see this has happened to several people

The contact owned a 2009 Acura MDX. While the contact's spouse was driving 5 mph pulling into a parking space, the vehicle inadvertently accelerated and crashed into a store. The contact was unsure if any warning indicators were illuminated. The air bags deployed and the driver sustained minor injuries, which did not require medical attention. A police report was filed. The vehicle was towed to a tow lot and deemed a total loss. The manufacturer stated that they would not send an inspector to diagnose the failure. The failure mileage was approximately 100,000.

While driving on the brooklyn-queens expressway (I 278 E)at a high rate of speed the car stalled nearly causing an accident, truck and tractor trailers came barreling down towards my stalled vehicle and abruptly changing lanes to avoid crashing into my car. I dialed 911 and the nypd highway unit sent a towtruck immediately to avoid accidents (I was petrified waiting for the tow) the dealer identified a throttle failure, replaced the throttle again for the second time.
