The PCM system does not work at all and brakes seem off - either they stop too hard or drag when pressing in them
My 2017 Silver FIAT 500 pop has a defective miles odometer that flashes. The car was purchased from Tobin Fiat of Las Vegas on 8/21/2017. I test drove this car to my home for 3 days before buying it. On day 2 it starting flashing. I returned to the dealer, reported it and was told it would be repaired. I have over 40 Videos on my cel phone that prove its defective over a 4 year period. Most resent issues on, 10/30/21, 11/1/21, 11/10/21. All 3 parties have refused to fix, repair or replace what causes the flashing...

miles indicator in my car. They said it doesn't exist so there is nothing to fix. The car was sent to the Fiat dealership in Henderson for a few days and they said it didn't flash while there so Fiat, Chrysler and Tobin Fiat of Las Vegas saw it as a none issue or as a customer complaint about nothing.
Car stopped and quickly slowed down without warning. I had very little time to steer car to the side of the road. The rbs/abs system started slowing the car on its own. I had only been going 30 mph, however had I been in a center lane on a freeway at 60 mph, I would have not been able to get it off the road.
The miles indicator flashes. Purchased 8/21/17 and still flashes. Dealership: tobin fiat 2550 s. Jones blvd. Las vegas, nv89146
