Typical repair cost, by problem

The standout problem on this generation is engine seizure and catastrophic failure — multiple documented cases of seized engines and broken crankshafts, with metal shavings found in the oil, often requiring a full engine replacement. This has been reported across a very wide mileage range, including some low-mileage failures, so don't assume a newer-feeling example is safe from this.

PROBLEM DETAILS

Engine seizure / catastrophic failure

Seized engine, broken crankshaft, metal shavings found in oil; owners describe the engine as 'blown'

Check engine light: On

Multiple documented cases of engine seizure and catastrophic failure, with broken crankshafts and metal shavings found in the oil — owners describe the engine as simply 'blown.' This has been reported across a very wide mileage range, including some failures at surprisingly low mileage, and often requires a full engine replacement. A failure this severe is typically preceded by check-engine-light warnings, unusual noise, or oil-pressure warnings.

$2,000 – $4,8004,800 – 145,000 mi

Engine oil leaks

Oil visible under the vehicle, oil consumption between services

Check engine light: Off

The most frequently named engine issue for this generation: oil leaks from oil pan gaskets, valve cover gaskets, the timing cover, and oil pressure sending units. An oil leak on its own doesn't reliably trigger a check-engine light unless oil pressure drops significantly.

$150 – $2,70125,000 – 160,000 mi

Starting / electrical issues

Intermittent failure to start (push-button ignition), battery/key fob problems, brake sensor failures

Check engine light: Off

Intermittent starting failures tied to the push-button ignition system, along with battery, key fob, and brake sensor problems.

$600 – $840

↑ Back to the problem table

Fuel system failures

Highway-speed stalling; fuel injector defects

Check engine light: On

Fuel pump failures causing stalling at highway speed and fuel injector defects. One documented report describes a fuel injector failure that burned through an entire tank of fuel within 30 miles — a severe, safety-relevant failure. A fuel-system fault like this reliably triggers a check-engine light.

One documented report describes an injector failure burning through a full tank in 30 miles. This is a severe failure, not a routine fuel-economy issue.

↑ Back to the problem table

Overheating / coolant issues

Cracked radiators, failed water pumps, hose failures, coolant mixing into engine oil

Check engine light: On

Overheating tied to cracked radiators, failed water pumps, hose failures, and in some cases coolant mixing into the engine oil. Overheating like this typically triggers a check-engine or temperature warning light.

$150 – $2,600

↑ Back to the problem table

Sensor problems (crankshaft, O2, throttle position)

Check engine light

Check engine light: On

A cluster of sensor failures — crankshaft position, oxygen, and throttle position sensors — each reliably triggering a check-engine light.

$450 – $700

↑ Back to the problem table

Headlamp failure

Headlamp failure, including cases where headlights randomly turn off while driving in auto mode

Check engine light: Off

Headlamp failure, including cases where headlights randomly turn off while driving in auto mode. This is among the more frequently reported issues on this generation, with 653 owner reports on file.

↑ Back to the problem table

AC compressor clutch failure

AC compressor clutch fails, often ending AC function entirely

Check engine light: Off

AC compressor clutch fails, often ending AC function entirely. This is among the more frequently reported issues on this generation, with 221 owner reports on file.

↑ Back to the problem table

Airbag warning light cluster (passenger seat sensor, control module, clock spring)

Erroneous airbag warning light, variously attributed to a passenger seat sensor malfunction, a control module fault, or a clock spring malfunction

Check engine light: Off

Erroneous airbag warning light, variously attributed to a passenger seat sensor malfunction, a control module fault, or a clock spring malfunction. This is among the more frequently reported issues on this generation, with 168 owner reports on file.

↑ Back to the problem table

Updated Timing Chain Tensioner to Correct Noise on Startup

Startup noise corrected by an updated timing chain tensioner

Check engine light: Off

Startup noise corrected by an updated timing chain tensioner. This is among the more frequently reported issues on this generation, with 94 owner reports on file.

↑ Back to the problem table

Software update to correct transmission issues

Transmission shifting problems addressed by a dealer software update

Check engine light: On

Transmission shifting problems addressed by a dealer software update. This is among the more frequently reported issues on this generation, with 87 owner reports on file.

↑ Back to the problem table

Ignition Coil May Fail

Ignition coil failure

Check engine light: On

Ignition coil failure. This is among the more frequently reported issues on this generation, with 77 owner reports on file.

↑ Back to the problem table

No Sound from Speakers

Speakers stop producing sound

Check engine light: Off

Speakers stop producing sound. This is among the more frequently reported issues on this generation, with 73 owner reports on file.
