The most-complained-about new car of every model year

Ask "what's the most-complained-about car?" and you'll get an argument. Ask it one model year at a time, against the federal complaint record, and you get a list — twenty-one winners, and a clear pattern in who keeps showing up.

The single most-complained-about vehicle of the last two decades is the 2010 Ford Fusion, with 5,124 NHTSA owner complaints. And one brand dominates the annual title: Ford holds the top spot in 10 of 21 model years — the Escape, Fusion, Focus and Explorer trading the crown through the 2010s.

The most-complained-about vehicle of every year

Why the raw count rewards best-sellers

Here's the honest part. A raw complaint total is driven by two things that have nothing to do with how good the car is: how many were sold, and how long they've been on the road. The vehicles on this list are, overwhelmingly, high-volume mainstream models — the Escape, Fusion, Camry, Sonata, Cobalt. More cars on the road means more owners who can file, so a popular car starts with a structural head start in any complaint tally. This is a count of complaints, not a per-capita failure rate; we don't have registration denominators, so treat the list as "where the most owner reports landed," not "the objectively worst-built cars."

The exposure effect is just as important, and you can see it in the chart: the numbers fall off a cliff after about 2020. The 2025 RAM 1500 tops its year with only a few hundred complaints — not because it's bulletproof, but because a car that's a year or two old simply hasn't had time to rack them up. A low number on a recent model year means "too new to tell," not "reliable."

What it's actually good for

Read correctly, the list is still useful in two ways. First, on the older model years — where every car has had a full life on the road — a runaway leader usually signals a real, well-documented defect pattern, not just popularity. The 2010 Ford Fusion, the 2006 Chevrolet Cobalt, the 2011 Hyundai Sonata: these top their years because they carried genuine, named problems, and the individual vehicle pages break down exactly which systems owners flagged. Second, it's a map of which nameplates to research harder before you buy — not a verdict, a starting point. Pull the specific year/make/model and read what owners actually reported.

The recent shift is worth a note, too. The last few annual winners aren't the old sedans and SUVs — they're newer Hondas and, increasingly, EVs. As the fleet electrifies, the complaint record is starting to follow; it's just early, and the volumes are still small.

How we did it

Source. NHTSA owner-complaint counts from our copy of the public NHTSA complaint database, computed live at publish time. For each model year 2005–2025 we took the single (year, make, model) with the highest total complaint count. Figures refresh with our weekly NHTSA sync. Full per-vehicle data is downloadable as the open Vehicle Reliability Scorecard (CC BY 4.0).

Caveat. Complaint counts reflect how often owners file, not a failure rate, and are unverified consumer reports. Volume tracks sales and time-on-road, so high-production, long-lived models accumulate more; recent model years are undercounted because their vehicles are young. Recall counts are NHTSA campaigns touching that vehicle, not necessarily for the most-complained component. Motorcycles are excluded. For the honest per-vehicle picture, always open the specific year/make/model page.
