When problems show up
No complaints for this year listed a mileage, so we can't say when problems show up.
Questions to ask the seller
- Were recalls 24V474000 (tires) and 19E044000 (transmission & drivetrain) done? Ask for the dealer printout, or check the VIN.
- Do the seats adjust, heat and lock in place properly?
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?
- Fiat sent dealers 90 repair notes for this car. Was this one done: “WiTECH Small Leak Verification Test (SLVT) - P0456-EVAP SYSTEM SMALL LEAK”?
From this year's own recalls, top problems, top repair bills and Fiat's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 2 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

Recalls 2
- Tires · recall issued 2024
The tire pressure monitoring system (TPMS) warning light may not illuminate as intended.
- Transmission & drivetrain · recall issued 2019
The Shifter Shaft may have been improperly manufactured with a through hole for the set screw rather than a blind hole, which may lead to the breakage of the Shifter Shaft.
Recall repairs are free at any dealer. A recall only matters if it's still open on that exact car, so check its VIN.

Every Fiat 500 year. 2018 is highlighted. Lower is better.
Newest year first. Red = worse than average, gray = about average, too new (2023+: a partial score, marked “partial”) or too few complaints to score. #1, #2… = that year's YouTube rank among the 4 Fiat 500 years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.

Is the 2018 Fiat 500 reliable?
We can't score it: only 5,370 were sold in the U.S. in 2018 (calendar-year sales), under the 20,000 we need for a fair per-car score. Owners filed 2 complaints with NHTSA in its first 3 years.
What are the most common 2018 Fiat 500 problems?
In owner complaints to the government, the parts named most are seats (50%) and brakes (50%). That is the share of complaints, not the share of cars that break.
How many recalls does the 2018 Fiat 500 have?
2 safety recalls (latest: tires). Recall repairs are free at any dealer; check a specific car's VIN at nhtsa.gov/recalls.
Does the 2018 Fiat 500 have transmission problems?
Transmission and drivetrain issues aren't among its top 5 complaint areas.
How much does the 2018 Fiat 500 cost in fuel a year?
About $650 to $3,000 a year, by the EPA's current estimate.
What Fiat 500 year is better than the 2018?
No year within 3 model years of it drew fewer complaints. Across every year, 2013 drew the fewest (a bit more than the average car's complaints).
The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
