general problems of the 2011 Mazda CX-7

The transmission just all of a sudden would not reverse the vehicle.

On 4/18/18 - while driving vehicle, all of a sudden and with no warning, pushing gas pedal, it reved up into gear, stayed there and then all of a sudden banged into next gear and proceeded to do the same through the remaining gears. Then the at light illuminated. I turned the car around and drove back to the office (this was at lunch time). When I left the office for the evening, the car now would not go into reverse. I ended up having it towed to a transmission shop. I was told that it needed a new transmission. Now I would probably be inclined to agree but the car does not even have 65k miles on it!!! everyone I have talked to said that is not normal for a transmission to go with that few miles on it. Something is very wrong here.

On 12/14/2015, I was driving about 60-65 mph on a maryland highway at around 10am. I was in the next lane beside the fast lane. The 2011 Mazda cx7 started to decelerate. I looked down at the gages to make sure I didn¿t inadvertently go into neutral. I was still in drive. I hit the brake, not coming to a complete stop, and then stepped back on the gas, pushing the gas pedal to the floor and the car would not accelerate. It went down to about 20 mph. In my rearview mirror I saw a tractor trailer coming toward me and there was no where I could move, and I could not see on the other side of the trailer to go into the next lane without hitting another vehicle. I was hit in the rear by the trailer. I had on my seatbelt and the airbag did not deploy. I checked for cars in the fast lane and slowly moved onto the shoulder. The driver of the truck followed me. I purchased the car used last year from mile one in baltimore, MD. The car fax for the vehicle was great, with no issues. I got oil changes every 6k miles, my last one being in September 2015, at jiffy lube. This was my first instance with any acceleration and deceleration issues. If there was an issue, I did not get any indication light on my dash board that there was an issue.

Vehicle exhibits sudden acceleration. Approx 25% to 35% of the time vehicle will lurch forward when accelerating from a stop. Vehicle behaves as if the accelerator if pressed down all the way, even though it is barely engaged. Sometimes the acceleration is so strong that the tires will break loose. Sudden acceleration starts at about 2mph and stops by 10mph. Approx 5% to 10% of the time will happen in reverse as well. On approx. Nov 1, 2014 this sudden acceleration caused an crash while the vehicle was being parked.

The contact owns a 2011 Mazda Cx-7. The contact stated when he turned the vehicle on and shift into drive gear all five doors fail to lock unless he manually locked them. The failure was not diagnosed by a dealer or local mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 4,200. Updated 1/16/cn the consumer stated when the vehicle was in drive, the doors would not lock automatically.
