NHTSA Complaint #11473798 — 2015 FIAT 500

Bought the vehicle used and it had zero issues. I bought 4 new tires and immediately after the RBS and ESC warning lights appeared but disappeared one day later. Fives days after the new tires the RBS & ESC warning lights reappeared but remained. I took it to the FIAT Dealership for a diagnostic and they stated that after following the flow chart it states to replace ABS Module due to internal failure. I held off on replacing the ABS module because a separate mechanic stated that it’s common with Fiats for the RBS & ECA warnings to appear after changing all tires. One month later the BRAKE warning light turned on (without the emergency brake in use) and the car began to jerk when in drive or when using the brakes (as I was driving). I had to drive slow with little pressure on the gas so that I would not have to use the brakes as every time I did the car would jerk very roughly and felt as if it was going to break.
