I really like my new 500L, but it does not like me. After six days, 350ml, it broke down in stop and go traffic on I-25 outside Denver. The twin clutch automatic heated up, smoked and therefore the system shut down. Had roadside assistance tow it back to the Fiat dealer. After sitting for three days, the car started okay and was drivable. The dealer could not find any problems, the engineer in Italy could not find any problem with the readout data. Their comment was that with the stop and go traffic the 500L twin clutch automatic acted "normally". Fiat USA is still working with me so hopefully there will be a positive outcome.
