NHTSA Complaint #11655543 — 2016 JEEP COMPASS

I recently got the catalytic converter and 02 sensor swapped which removed the check engine light. My vehicle was running perfect. The I drive it today. Made a right turn, next thing you know the vehicle starts shaking and such and won’t go over 20 mph. I take it to the mechanic. They’re telling me the reader isn’t picking up the problem. Invalid data. I looked online and multiple people are having the same problem. My thing is I was overcharged charged 25,000 for this vehicle from Sam at jeep, Chrysler, dodge on route 300 Newburgh New York 2 years ago.
