What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving not able to accelerate , loss of power and check engine light . By turning the engine off sometimes resets and sometimes doesn't.
Also, the check engine light won't go off. Even after 4 times ($2,000) to a service garage. There are [dealer] my area. Not even the dealer where I purchased it will work on it.
The issue looks similar to fiat 500l 2014 recall for transmission software. The problem happens while driving for the first time of the day. The automatic gear doesn't shifts even if the speed goes higher. It take almost a mile or 2 for the transmission to function properly.
