$150 – $3,850

Typical repair cost, by problem

The most notable organic (non-recall) issue we found is timing chain failure — chain slack leading to major engine damage, documented at $3,500, the single most expensive organic repair in the available data for this vehicle. Separately, this generation has two issues we're treating as recall/campaign territory rather than routine wear — a recalled fuel pump control module and a widely-reported steering column lock defect that can prevent the car from starting — see the recall notice below rather than the problems list above for those.

PROBLEM DETAILS

Timing chain failure

chain slack that, left unaddressed, leads to major engine damage

Check engine light: On

This is the most severe non-recall problem for this generation: timing chain failure, where chain slack leads to major engine damage. One documented case at $3,500 and 103,000 miles is the most expensive single non-recall engine repair reported for this vehicle (roughly $2,800-$3,850). Timing chain problems commonly trigger timing-related fault codes, so we have this marked as typically setting a check-engine light.

$2,800 – $3,850103,000 mi

single documented figure ($3,500) widened ±10-20% into a range; the most expensive organic engine repair found in.

PCV valve failure

a high-pitched whistling or shrieking sound

Check engine light: On

PCV valve failure is reported across a very wide mileage range — 22,000 to 85,000 miles, including early-life failures. The telltale symptom is a high-pitched whistling or shrieking sound. A failed PCV valve typically causes a vacuum leak, which can trigger a lean-condition check-engine light.

$150 – $1,50022,000–85,000 mi

Water pump failure

a coolant leak, or noise coming from the water pump

Check engine light: Off

Water pump failure shows up as a recurring issue, with a documented cost range of $875 to $1,800 that we're using as-is since it's. Reported between 69,000 and 111,000 miles. This is a mechanical coolant-system fault, so it doesn't typically trigger a check-engine light unless it progresses to overheating.

$875 – $1,80069,000–111,000 mi

↑ Back to the problem table

High-pressure fuel pump failure

a loss of power, or the engine stalling

Check engine light: On

A high-pressure fuel pump failure causing loss of power and stalling shows up across a wide mileage range (34,000-110,000 mi), with a documented cost range of $580 to $1,500. Note: this is a distinct component from the fuel pump control module covered by a formal recall for this generation (Campaign 17V509000) — but we haven't fully verified whether the two overlap in practice. We're including this because it's independently documented across a meaningful mileage and cost range, but check your VIN regardless before assuming this isn't recall-covered. Fuel delivery faults like this typically trigger a check-engine light.

$580 – $1,50034,000–110,000 mi

may overlap with, or be distinct from, the recalled fuel pump control module (Campaign 17V509000) — not fully verified. Included because it's independently documented, but check your VIN regardless.

Thermostat failure

hard starting, along with a check engine light

Check engine light: On

Thermostat failure is reported across a wide mileage range (22,000-110,000 mi), with a documented cost range of $250 to $580. Owners specifically reported a check engine light alongside hard starting.

$250 – $58022,000–110,000 mi

check-engine-light status is directly sourced from owner reports for this item, not a mechanical judgment call.

↑ Back to the problem table

Oil leaks (multiple locations)

oil leaking from more than one location on the engine

Check engine light: Off

One notable report described oil leaks "from 3 different locations" on the engine, part of a broader pattern of oil-seal-related leaks across this generation, with a documented cost range of $692 to $1,500. Reported between 78,000 and 148,000 miles. This is a mechanical oil-leak fault, not a sensor or emissions issue, so it doesn't typically trigger a check-engine light.

$692 – $1,50078,000–148,000 mi

Coil pack misfire

a misfire under load

Check engine light: On

Coil pack failure causing a misfire under load is reported across a wide mileage range (78,000-150,700 mi), with a documented cost range of $150 to $425. Misfires typically trigger a check-engine light.

$150 – $42578,000–150,700 mi

↑ Back to the problem table

Turbocharger component issues (turbo trims)

surging or whistling from the turbo, or a valve failure

Check engine light: On

Turbocharger trim component issues — surging, whistling, and valve failures — show up across an unusually wide mileage range (22,000-170,000 mi), with a documented cost range of $175 to $415. Turbo boost-related faults commonly trigger a check-engine light, so this is marked On.

$175 – $41522,000–170,000 mi

ABS light due to ABS control module failure

ABS warning light triggered by a failed ABS control module

Check engine light: Off

ABS warning light triggered by a failed ABS control module. This is among the more frequently reported issues on this generation, with 255 owner reports on file.

↑ Back to the problem table

Digital display on instrument cluster may fail

Instrument cluster digital display fails

Check engine light: Off

Instrument cluster digital display fails. This is among the more frequently reported issues on this generation, with 184 owner reports on file.

↑ Back to the problem table

Water intrusion from clogged sunroof and plenum tray drains damages control modules

Water accumulates from clogged sunroof and plenum tray drains, damaging electronic control modules

Check engine light: Off

Water accumulates from clogged sunroof and plenum tray drains, damaging electronic control modules. This is among the more frequently reported issues on this generation, with 116 owner reports on file.

↑ Back to the problem table

Check engine light due to catalytic converter fault

Check engine light from a catalytic converter fault

Check engine light: On

Check engine light from a catalytic converter fault. This is among the more frequently reported issues on this generation, with 90 owner reports on file.

↑ Back to the problem table

Flasher relay failure, erratic turn signal

Turn signal behaves erratically due to a flasher relay failure

Check engine light: Off

Turn signal behaves erratically due to a flasher relay failure. This is among the more frequently reported issues on this generation, with 66 owner reports on file.

Odor from HVAC vents

Unpleasant odor coming from the HVAC vents

Check engine light: Off

Unpleasant odor coming from the HVAC vents. This is among the more frequently reported issues on this generation, with 52 owner reports on file.

↑ Back to the problem table

Check engine light due to faulty torque converter

Check engine light traced to a faulty torque converter

Check engine light: On

Check engine light traced to a faulty torque converter. This is among the more frequently reported issues on this generation, with 49 owner reports on file.

This generation is tied to Campaign 17V509000 (Fuel System, Gasoline — also referenced as manufacturer recall "20AE"), covering a fuel pump control module that can cause stalling and no-restart after a dealership repair. Separately, owners widely report a steering column lock defect that can prevent the car from starting — one complaint noted "hundreds to thousands" of similar reports on SaferCar.gov — though no campaign number has been confirmed for it. A third campaign, 08V235000, covers engine surge issues distinct from the organic engine wear items above. Two further campaigns cover airbags: 18V148000 and 16V078000, the latter Takata-related.
