Start my diagnosis →Check engine light, surging idle, hesitation
Check engine light: On
Throttle position sensor failures producing a surging idle and hesitation. A TPS fault reliably triggers a check-engine light.
Poor gas mileage
Check engine light: On
An oxygen sensor failure (a shorted rear bank 1 sensor in our documented case) producing poor gas mileage. A failed O2 sensor reliably triggers a check-engine light.
Hiccuping or hesitation at specific speeds
Check engine light: On
EGR valve issues producing hiccuping or hesitation at specific speeds. An EGR fault typically triggers a check-engine light.
Not detailed beyond the named fault in our source sample
Check engine light: On
A fuel pump failure at 120,000 miles. A fuel delivery fault like this typically triggers a check-engine light.
Faulty ignition switch; loose gas cap triggering check engine light
Check engine light: On
Faulty ignition switches and loose gas caps, the latter reliably triggering a check-engine light on its own.
Various, throughout the engine's lifespan
Check engine light: On
Knock sensor and oil pressure sensor failures reported across the engine's lifespan. These sensor faults typically trigger a check-engine light.
Sudden engine shutdown while driving, accompanied by loss of power steering and power brake assist
Check engine light: Off
NHTSA complaints describe sudden engine shutdowns while driving with accompanying loss of power steering and brake assist. Not confirmed as recall-covered.
Engine performance problems, stalling, or failure to start, traced to a failed crankshaft position or angle sensor
Check engine light: On

Alternator failure, addressed by an improved replacement alternator
Check engine light: Off
Alternator failure, addressed by an improved replacement alternator. This is among the more frequently reported issues on this generation, with 23 owner reports on file.
This generation has a confirmed valve cover gasket/alternator recall (Campaign 976) — but the repair reportedly doesn't always hold, with leaks recurring after service. Also confirmed: service brakes (Campaign 21V936000), exterior lighting (Campaign 13V113000), airbags (Campaign 11V472000), and an underbody corrosion coverage program (Campaign 947 — check your eligibility before assuming coverage).

Symptoms described here can have multiple causes, and the presence of a commonly reported problem does not mean your vehicle has it.

This generation has a confirmed recall for a valve cover gasket leak that can damage the alternator and cause stalling — but multiple owners report the recall repair itself doesn't reliably hold, with leaks recurring after service. Separately, NHTSA data describes engine stalling paired with loss of power steering and brakes — the same combination is also reported on the Jeep Patriot.
