“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. …”
NHTSA complaint #10810217, filed 2015-12, 61,000 miles“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. …”
NHTSA complaint #11089204, filed 2018-04, 64,000 miles“Purchased (new) - july 4th, 2011. One month in, the front driver tire blows out on the 55 freeway in costa mesa. The car is driven to the dealer the next day - to have a tire placed on. The price was surely surprise surprise - $250.00. We push to know why the tire was so expensive, it's because the size is new for this size vehicle and there's one maker of the tire. Bridgestone. We pay for it begrudgingly, and go about our way. February 6th, 2015, 3 years, 6 months of owning the vehicle. …”
NHTSA complaint #10683090, filed 2015-02, 64,262 miles“Car was stationary at the time. I was attempting to back out of a driveway, and the car would not engage into reverse. I was able to push it out and drive it to smithaven Mazda. This car was able to run in drive but would bog down when the transmission would try to shift. The dealership was closed at the time and the next day I spoke to the service manger at Mazda and he performed a diognostic on the car. He called later that day to inform me that the transmission was blown and the cost to replace it would be $4,300. This car has 72,000 miles on it and was purchased new in 2011. …”
