Typical repair cost, by problem

This generation has two confirmed recalls, and some owners report their VIN was not covered: an electrical system recall for stalling (Campaign 14V567000) and an ignition cylinder recall for the key seizing or sticking between positions. Check whether your VIN is covered before assuming a repair is out of pocket. Separately, NHTSA data includes reports of engine fires linked to wire harness failures. That has not been confirmed as a specific recall, so it is not listed as a routine repair below.

PROBLEM DETAILS

Glow plug / glow plug control module failure (3.0L diesel)

Cold starting difficulty

Check engine light: On

Glow plug and glow plug control module failures on the 3.0L diesel variant, causing cold-starting difficulty. Reported costs start around $500, with one far higher outlier case that likely reflects a cascading failure rather than a typical repair. A glow plug system fault typically triggers a check-engine light on this diesel variant.

$500 – $7,500+

Swirl motor failure (3.0L diesel)

Not detailed in our source sample

Check engine light: On

Swirl motor failure on the 3.0L diesel variant. Intake/swirl-motor faults on diesels typically trigger a check-engine light.

↑ Back to the problem table

Water pump failure (multiple engine variants)

Overheating risk

Check engine light: Off

Water pump failures across multiple engine variants (3.0L diesel, 5.7L V8, 4.7L V8, 3.7L V6), creating overheating risk. A coolant leak on its own typically doesn't trigger a check-engine light.

$800 – $1,020

↑ Back to the problem table

Ignition coil failure requiring full plug/wire replacement (4.7L V8)

Misfiring

Check engine light: On

Ignition coil failure on the 4.7L V8 variant requiring a full set of 16 spark plugs and wires to be replaced. A misfire like this triggers a check-engine light.

↑ Back to the problem table

Phantom stall condition (4.7L V8)

Unexplained stalling, resolved in one case by fabricating EMI shielding

Check engine light: On

An unusual, unexplained stalling condition on the 4.7L V8 variant, resolved in one documented case by fabricating EMI (electromagnetic interference) shielding — an aftermarket fix, not a standard dealer part replacement. Stalling like this typically triggers a check-engine light.

Unusual resolution method (aftermarket EMI shielding, not a standard part).

↑ Back to the problem table

Transmission stuck in fourth gear (limp mode)

Transmission shifting issues, stuck in 4th gear

Check engine light: On

Transmission control faults causing the vehicle to stick in fourth gear (limp mode). A transmission limp-mode fault like this typically triggers a check-engine or transmission warning light.

↑ Back to the problem table

Loss of power steering

Loss of power steering

Check engine light: Off

Power steering system failures causing a loss of steering assist. A power steering fault is mechanical/hydraulic and doesn't trigger a check-engine light.

This generation has two separate confirmed recalls, and some owners report their VIN was not covered by either: an electrical system recall (Campaign 14V567000 — unexpected stalling or shutdown while driving) and an ignition cylinder recall (the key seizing or sticking between positions). Separately, NHTSA data includes serious reports of engine fires linked to wire harness failures, and of airbags deploying without an impact. Neither is confirmed as a recall, so neither is listed as a routine repair below. Enter your VIN to get the confirmed, current recall picture for your specific car.
