Typical repair cost, by problem

NHTSA data for this generation is dominated by recalls: roughly 50 of 169 sampled complaints are tied to Campaign 19V904000 — a brake hydraulic control unit / ABS recall shared with the Ford Fusion, which is built on the same platform. One complaint describes the brake pedal remaining on the floorboard on multiple occasions, with the vehicle reportedly left unrepaired.

PROBLEM DETAILS

Engine mount shimmy

engine shimmy at red lights

Check engine light: Off

One documented upper engine mount shimmy at $300 at 78,120 miles. We've widened it into a $240-$330 range. An engine mount issue is mechanical and doesn't trigger a check-engine light.

$240 – $33078,120 mi

Computer module / check engine light issues — one very early-life

a check engine light traced to the engine/transmission computer module

Check engine light: On

Two separate reports: a check engine light from a bad signal at 79,000 miles (cost bundled into another repair, not separately itemized), and a separate case requiring computer reprogramming at just 1,000 miles — essentially a day-one software issue. By definition, this problem involves a check-engine light.

1,000 – 79,000 mi

The 1,000-mile case is essentially a day-one software issue, likely resolved under new-car warranty.

PTU line gas smell

a gas smell from the ventilation system

Check engine light: Off

One documented report of the ventilation system producing a gas smell, tied to the PTU (power transfer unit) line, at 66,000 miles. Worth taking seriously given the safety implications of a gas smell inside the cabin, though it was not described as a fire/explosion risk in this report. This is not the kind of fault that triggers a check-engine light.

66,000 mi

Not described as a fire/explosion risk, but a gas smell inside the cabin is worth taking seriously.

Battery cable corrosion

corrosion buildup on the battery cable

Check engine light: Off

One documented report of battery cable corrosion buildup at 39,000 miles. A corroded battery cable typically doesn't trigger a check-engine light.

39,000 mi

Mass airflow sensor vacuum line issue

an incorrect fuel mixture from a MAF sensor vacuum line issue

Check engine light: On

One documented mass airflow sensor vacuum line issue causing an incorrect fuel mixture, at $500 at 41,000 miles. We've widened it into a $400 - $550 range. A sensor fault like this triggers a check-engine light.

$400 – $55041,000 mi

Harsh or delayed shifting of automatic transmission

Automatic transmission shifts harshly or with a delay

Check engine light: On

Automatic transmission shifts harshly or with a delay. This is among the more frequently reported issues on this generation, with 243 owner reports on file.

This generation has a confirmed brake hydraulic control unit / ABS recall (Campaign 19V904000) — the same recall found on the Ford Fusion, confirming both vehicles share this defect via Ford's CD3/Fusion platform. One NHTSA complaint (ODI 11608299) describes the brake pedal remaining on the floorboard on multiple occasions, with the vehicle reportedly left unrepaired despite the ABS/HECU needing replacement. This generation also has extensive Takata airbag recalls (Campaigns 16V384000, 16V385000, 18V046000, 21V158000) — roughly 85 of 169 sampled complaints relate to these.
