Just trying to figure out wtf if going on....if CarMax needs to take car back. (Had it around 2 years from them, put ~20k on it. I bought multiecuscan but before i could buy an obd all this went down and im so sick of throwing money into this thing so i havent done that just yet. figured the fiat people would know more than me but who knows...


Mid July: radio stopped working; odometer started flashing when it wouldn’t work.

But sometimes… the radio would randomly start working again for a bit, then would stop and odometer would flash again…on and off. Someone mentioned might need a proxy alignment?

Mid August: no air blowing. Checked fuses, the one for the blower motor was blown, went to [LOCAL STORE] and asked for the same one. Replaced and started working again.

Early September: Left Napa early AM with full tank of gas headed to Amador (~2.5 hours away). Arrived around11:30am and car sat in 105* weather all day in the sun. Left Amador around 3pm and pulled out of the parking lot to find a gas station to fill up again before I headed back to Napa (had around ~¼ tank of gas left) Was in a pretty hilly area and after I got to the top of a big hill, I noticed the car was having trouble accelerating, and then the instrument panel screen started to flash something about Hill Control Traction/ESC/Hill Start Unavailable, pulled out my phone to Google really quick if that means to stop driving, and before I could even open Google instrument panel said Check Transmission and the car went into limp mode so I pulled right onto the shoulder of the high way and turned the engine off, and by then the CEL light was on. I tried to use my phone, and the radio was randomly working but suddenly made a SUPER loud, electronic noise that wouldn’t stop until I took the key out.

Got it towed home in Napa. Tow truck driver was able to drive it into the driveway.

Plugged in my BMW’s old OBD reader and the only codes were:
[SEE PDF FOR PHOTOS]
U0077

P1607

Towed car to [LOCAL IMPORTS SHOP]. They said the issue was that [LOCAL STORE] gave me the wrong fuse when the blower fuse blew back in August. And that the radio was a “blue and me” problem and very expensive to fix, and to just buy an aftermarket radio.

Picked car up, headed to gas station because light was on, but about 4 minutes later instrument panel started to flash Service Fuel Cut-Off/ESC/Check Transmission/CEL and went into limp mode about 4 minutes later.

Towed car back to [LOCAL IMPORTS SHOP], who then said there’s a whole list of codes showing that only Fiat can read(?):
[SEE PDF FOR PHOTOS]
U0001

U110C

U110E

U0418

U0077

U0001-88

U0001-87


Towed to Fiat Dealership in Santa Rosa. They said it was just low on gas… Picked up from Fiat dealership and window wouldn’t go up. Realized they broke window regulator and scratched the tint when doing so (GRRRRRR)

Drove from Santa Rosa to Napa.

The next day drove from Napa to Fairfield, Fairfield to American Canyon, back to Napa.

Day after, drove about two streets away and car is back in limp mode, same stuff flashing on instrument panel.

Plugged in my BMW’s OBD reader again just for the hell of it, and it had these codes:
[SEE PDF FOR PHOTOS]
U1106-CAN C SIGNAL MISSING

U0077-CONTROL MODULE COMMUNICATION BUS OFF

U0002-88-CAN C BUS OFF PERFORMANCE

Got the car towed to CarMax. And they are saying it just needs a new battery. I guess it was dead because the tow truck driver left the key in it. But they still stand by it just needs a battery....wtf. thoughts?

I don't claim to be an expert on your vehicle (too new for me) however some of your problems may be related to the "Blue & Me " infotainment system, there are many who have mentioned issues with that on Fiat Forum and with possible fix.
One of my daughters bought a Punto Evo with it and I gave her strict instructions not to use it!!!
Apart from that, if you have "Stop/Start" system then a correct battery for that must be fitted and in a certain installation method , so if wrong battery or a battery fault /charging system etc. you will get many error codes on code reader.
By the way if you keep with Fiats I would advise getting the Fiat diagnostic tool that many on Forum use MES (MultiEcuScan) and they will be able to advise on usage.

Your Can C bus is off...this possibly means there's a wire broken leading to your gearbox. Get an auto-electrician to come to your house. If you take this to a garage they'll likely say you need a new gearbox and try to charge you big bucks for a broken wire.
