“Was on the highway takings grandkids home and the car just cut off right in the middle of a busy highway. It took several tries to get it to start again but it stayed on only long though for me to get it on the shoulder. We could have been in a serious wreck. It is only by the grace of god and functional hazard lights that we and other vehicles weren't injured. We had to be towed because we were too far from an exit to risk trying to drive it any further!”
NHTSA complaint #10682419, filed 2015-02, 85,341 miles“1 - there is up to a two second delay when quick acceleration is required. At times it feels as if the engine completely stalled. 2 - the vehicle often will not downshift to slow the vehicle on a hill. I could be in 5th gear at around only 1800 RPM, and when I downshift twice, it will not go to 3rd. I often have to downshift up to 6 times for it to respond and switch to third. I need to take my eyes off the road to constantly check if I'm in the gear I select. 3 - the parking/emergency break will not hold the fully loaded vehicle on a hill. …”
