“As I backed out of a parking space, the car surged & I hit another parked car behind me. Even though I had my foot on the brake, the car accelerated for a few seconds. I then placed the other foot on top of the right foot & put the gear into park & the car stopped.”

NHTSA complaint #10506069, filed 2013-04, 72,000 miles“When accelerating suddenly the vehicle would just shift out of gear, make a loud clunking noise and violently thrust forward and then back. It happens a lot when trying to accelerate onto a highway. It is very scary feeling. It is a sudden jolt. When we took the car to the dealership the repairman said has seen a lot of the harsh shifting failure with the transmission with the Montego.”
NHTSA complaint #10759088, filed 2015-08, 63,512 miles“After the engine warms up, upon acceleration and the automatic transmission is shifting gears from 1 to 2, 2 to 3 and 3 to 4 there is a stuttering and often a jerking when the automatic transmission is shifting. This jerking also occurs upon slow braking when the transmission is down-shifting from gears 4 to 3 to 2 to 1. It's getting worse!!”
