Manufacturer file
What the FIAT records can tell us
The FIAT file currently stops at 3 nameplates: 124 Spider, 500, 500X. Those 17 model-year entries contain 376 owner complaints. The missing denominator matters because these records do not say how many vehicles were on the road.
Electrical System appears most often in the component tags, with 97 mentions. A single complaint may carry several tags. I use the total as a prompt to read that system's contract terms, not as odds that a repair will happen.
Across the same model years, NHTSA records show 32 recall campaigns and 1,570 manufacturer communications. Recall repairs are handled separately from a paid service contract, while communications include far more than defects.
