“Shifting 1st to 2nd and 2nd to 1st is very hard and jolting. It hesitates and doesn't go immediately which could cause an accident.”

“When I'm coming to a stop and the vehicle starts downshifting, the last shift feels like the tranny is going to fall out. Forceful jerk and clunking noise. It's sporadic. One week it's almost every day, one week it seems fine. The dealership said they have heard this a lot and laughed when they told me the manufacturer has told them it's normal. It's definitely not normal.”

Should you keep driving it?

This page can't tell you that. 0 of 33 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
