The 25 Most Complained-About Vehicles in Federal History

The federal complaint database has collected owner grievances against passenger vehicles for three decades. Rank every model year by the number of complaints filed against it, and the top of the list is not a random assortment of unlucky cars. It is a short history of specific engineering decisions that went wrong at scale.

The list

Counted from an August 2026 snapshot of the federal file, covering complaints received since 1995 against vehicles of model year 1981 or later. Each vehicle links to its full file.

Fifteen blue ovals

Fifteen of the twenty-five most complained-about vehicles in federal history are Fords, and thirteen of those fifteen are from a single ten-year span, the 2007 through 2017 model years. That is not one bad car. It is three bad ideas, each repeated across a nameplate.

The first is the PowerShift transmission, a dry dual-clutch automatic that shudders, hesitates, and eats clutches, which puts the 2012 and 2014 Focus in the top fifteen on the strength of one component. The second is the 2010 Fusion and its two siblings, the 2011 and 2012 model years, all three of which sit in the top twenty-five largely for electric power steering that cuts out and throttle bodies that stall. The third is the Escape, which appears three times, the 2010, 2013, and 2017 model years, with the 2013 Escape carrying the engine fire recalls of its smallest EcoBoost engine.

Add the 2013 F-150 and 2013 Edge, both dogged by the larger EcoBoost engine's moisture-related misfire, and the pattern is complete: a decade in which Ford introduced a new transmission, a new steering system, and a new engine family, and owners of each filed complaints by the thousand.

The one-component cars

Almost nothing on this list got there by being bad at everything. The 2011 Sonata is an engine story, the Theta II bearing failures that grew into recalls, an extended engine warranty, and federal enforcement. The 2014 Cherokee and the 2015 Chrysler 200 are both nine-speed transmission stories, the same gearbox in two bodies. The 2018 Ram 2500 is a steering story with a nickname, the death wobble. The 1995 Windstar is a head gasket story. The 2018 CR-V is an engine oil dilution story.

Pull any of those files and the fault profile shows the same shape: one bar that dwarfs the rest. A vehicle rarely becomes notorious for a little of everything. It becomes notorious when one system fails the same way for tens of thousands of owners.

The ones with a body count

Two entries earned their place through something worse than expense. The 2006 Chevrolet Cobalt is the ignition switch case, a switch that could slip out of the run position and disable the airbags, which became one of the largest and most scrutinized recalls of the following decade. The 2007 Camry and 2010 Prius are the two vehicles on this list from the unintended-acceleration era, when complaint volume against Toyota rose with the news coverage and stayed there.

Those two cases also show something about how the file works: when a defect becomes a national story, owners who would never have filed a complaint go looking for the form. Part of what these numbers measure is attention. That is not a reason to discount them. It is a reason to read the vehicle's own file rather than the ranking.

What this list is not

It is not adjusted for sales. The F-150 has been the best-selling vehicle in America for decades, so a complaint rate that would be unremarkable on a low-volume car produces a top-ten total. The 1997 F-150 is on this list partly because there were so many of them and they have had nearly thirty years to break.

It is not a measure of how likely any one car is to fail. It is a count of filings, made by owners, not verified by the agency, and shaped by how expensive, dangerous, and newsworthy each failure was. Read it as a map of where the pain concentrated, and then read the file on the specific car in front of you.
