Typical repair cost, by problem

There is limited repair data for this vehicle, so the problems below are a starting point rather than a complete picture. NHTSA data is heavily airbag-dominated, and includes a genuinely serious safety pattern distinct from the standard Takata inflator recall: non-Takata airbag campaigns tied to actual non-deployment failures in real crashes, including one head-on collision where "not a single airbag in the entire vehicle deployed," resulting in a fractured neck. This is a serious, unresolved safety issue rather than routine wear and tear — check your VIN for open recalls. Separately, three of the problems below are priced in Euros (a European-market data point), not U.S. dollars, and have not been converted given exchange-rate uncertainty.

PROBLEM DETAILS

Timing chain rattling

a rattling noise from the timing chain

Check engine light: On

One documented timing chain rattle repair at €180 at 62,000 miles — a European-market data point, not converted to USD given exchange-rate uncertainty. That works out to a range of roughly €144-€198. Timing-related engine faults typically trigger a check-engine light.

€144 – €198 (not USD)62,000 mi

Reported in Euros, a European-market data point — NOT converted to USD given exchange-rate uncertainty.

Camshaft VVT sprocket issue

engine noise and power loss

Check engine light: On

One documented camshaft VVT sprocket repair at €200 at 46,220 miles — another European-market figure, not converted to USD. That works out to a range of roughly €160-€220. This was reported at the same mileage as the valve shaft sealing/oil consumption problem below — it may be the same underlying repair visit rather than two independent failures. VVT/timing-actuation faults typically trigger a check-engine light.

€160 – €220 (not USD)46,220 mi

Reported in Euros, not converted to USD. Same mileage as the valve shaft sealing problem below — possibly the same repair visit.

↑ Back to the problem table

Valve shaft sealing failure (oil consumption)

oil consumption from failed valve shaft seals

Check engine light: Off

One documented case of oil consumption tied to valve shaft seal failure at 46,220 miles — the same mileage as the camshaft VVT sprocket problem above, so this may be the same repair visit rather than a separate failure. Gradual oil consumption typically doesn't trigger a check-engine light on its own unless it becomes severe.

46,220 mi

No cost figure given. Same mileage as the camshaft VVT sprocket problem above — possibly the same repair visit.

Water pump / thermostat leak

leaking and noise from the water pump/thermostat

Check engine light: Off

One documented water pump/thermostat leak at $850 at 105,000 miles — high mileage, reading as expected wear. We've widened it into a $680 - $940 range. A coolant leak on its own typically doesn't trigger a check-engine light.

$680 – $940105,000 mi

High mileage — reads as expected wear.

Heat shield rattling

a rattling noise from the heat shield

Check engine light: Off

Reported twice: a rattle at 37,700 miles, and a separate rattle at 135,000 miles traced to rusted mounting bolts. A loose heat shield is a cosmetic/noise issue, not a fault that triggers a check-engine light.

37,700 mi and 135,000 mi

No cost figure given for either report.

Alternator belt failure

the alternator belt slipping, then breaking

Check engine light: Off

One documented alternator belt failure at $200 at 74,000 miles — the belt slipped, then broke. We've widened it into a $160 - $220 range. A belt failure is a mechanical fault, not one that triggers a check-engine light on its own.

$160 – $22074,000 mi

Air/fuel mixture sensor malfunction

a malfunctioning air/fuel mixture sensor

Check engine light: On

One documented air/fuel mixture sensor failure at $500 at 53,800 miles — the most expensive single repair in this vehicle's sample. We've widened it into a $400-$550 range. A sensor fault like this typically triggers a check-engine light.

$400 – $55053,800 mi

Starter/ignition no-start issue

the engine not starting right away

Check engine light: Off

One documented report of the engine failing to start right away, at just 47 miles — essentially a day-one issue, most likely resolved under new-car warranty. A no-start condition where the engine never actually runs typically doesn't set a check-engine light.

47 mi

Reported at just 47 miles — essentially a day-one issue, likely resolved under new-car warranty.

Vibration due to damaged engine mount

Vibration traced to a damaged engine mount

Check engine light: Off

Vibration traced to a damaged engine mount. This is among the more frequently reported issues on this generation, with 35 owner reports on file.

↑ Back to the problem table

NHTSA data for this generation includes a serious, unresolved safety pattern: airbag non-deployment in real crashes, referenced under Campaigns 14V168000, 17V006000, and 18V024000 — distinct from the standard Takata inflator recall (Campaign 16V340000), which this generation also has. One complaint describes a head-on collision in which no airbag in the vehicle deployed, resulting in a fractured neck. We also found an unrelated NHTSA-only report of a circuit board smoking near the driver door window at 25 mph, serious enough that a mechanic had to disconnect it to prevent fire — this wasn't independently corroborated and needs a closer look.
