Typical repair cost, by problem

This vehicle's 2.0L Ecotec turbo engine shows a notably high concentration of early-life issues (as early as 7,200-8,000 miles) alongside expected higher-mileage wear, which points to an early-production quality issue rather than normal wear. Separately, a serious brake-pedal-sticking issue (GM Technical Service Bulletin PIC5692D, tied to a documented 45 mph collision) is covered in the recall notice rather than with the common problems below.

PROBLEM DETAILS

Turbocharger failure — some very early-life

turbocharger failure or fault codes

Check engine light: On

Reported at least 3 separate times on this generation's 2.0L Ecotec turbo engine: outright failure at 52,000 miles, "engine noise continued" at just 7,300 miles — essentially day-one — and a turbo bypass valve throwing fault code P2261 at 36,880 miles. No cost figures were given for any of these three cases. The 7,300-mile failure is notably early and, combined with a separate early-life engine mount noise complaint at 7,200 miles, suggests some units may have left the factory with an issue rather than developing one through wear. A turbo fault code like this triggers a check-engine light.

7,300 – 52,000 mi

No cost figures given for any of the 3 reported cases. The 7,300-mile failure is notably early — possible early-production quality issue.

Major multi-component failure — water pump, turbo seals, timing chain guide

loud noise and an oil leak from a combined failure

Check engine light: On

One documented combined failure of the water pump, turbocharger seals, and a fractured timing chain guide, at $6,000 at 100,750 miles — the most expensive single engine repair found in this sample. We've widened it into a $4,800-$6,600 range. A failure this extensive would trigger a check-engine light.

$4,800 – $6,600100,750 mi

Cylinder head failure — severe

a dramatic cylinder head failure

Check engine light: On

One documented, severely-described failure at 58,000 miles: "sucked a valve into the piston head." A failure this severe would trigger a check-engine light.

58,000 mi

No cost figure given, though the failure description is severe.

Timing chain / balance chain noise — some very early-life

vibration or noise from the timing/balance chain

Check engine light: On

Reported at least 3 times: "bad vibration and noise" at 77,424 miles, "balance chain noise" at just 8,000 miles — very early — and belt tensioner chatter at 42,000 miles. No cost figures were given for any of the three. Timing-related noise like this often triggers a check-engine light.

8,000 – 77,424 mi

No cost figures given. The 8,000-mile case is notably early — possible early-production quality issue.

↑ Back to the problem table

Serpentine belt / tensioner issues

chirping or squealing from the belt area

Check engine light: Off

Reported twice: a chirping noise at 49,000 miles, and loud squealing with vibrations at 27,500 miles. No cost figures were given for either case. A belt/tensioner noise on its own typically doesn't trigger a check-engine light.

27,500 – 49,000 mi

No cost figures given for either case.

↑ Back to the problem table

Camshaft solenoid / intake actuator issues

rough idle with fault codes P0010/P1101, or an intake actuator failure

Check engine light: On

Camshaft solenoid failure causing rough idle, with fault codes P0010 and P1101, at 40,000 miles (no cost given); a separate intake actuator failure at 59,000 miles (no cost given); and intake/exhaust solenoids replaced for $500 at 98,704 miles. We've widened the one costed case into a $400-$550 range. These are sensor/actuator faults that trigger a check-engine light — confirmed directly by the P0010/P1101 codes.

$400 – $55040,000 – 98,704 mi

Only 1 of 3 reported cases has a cost figure.

Catalytic converter failure

a hole in the catalytic converter

Check engine light: On

One documented catalytic converter failure — "hole in unit" — at $950 at 84,000 miles. We've widened it into a $760-$1,045 range. A catalytic converter fault triggers a check-engine light.

$760 – $1,04584,000 mi

↑ Back to the problem table

Sensor / emissions issues (MAF sensor, fuel filler cap, emission control solenoid, crankshaft sensor)

a check engine light from a sensor fault

Check engine light: On

Several distinct sensor faults: check engine light traced to the MAF sensor/fuel filler cap ($600 at 45,400 miles, widened to $480 - $660), an emission control solenoid ($250 at 49,000 miles, widened to $200-$275), and a crankshaft sensor (warranty-covered at 54,000 miles, no cost given). We're presenting the combined $480 - $707 range across the costed cases. Sensor faults like these trigger a check-engine light.

$480 – $70745,400 – 54,000 mi

This entry covers three sensor problems (MAF/fuel cap, emission control solenoid, crankshaft sensor). The crankshaft sensor case was warranty-covered with no cost given.

This generation has a confirmed suspension recall for toe link fracture (Campaign 20V764000) and a confirmed exterior lighting recall (Campaign 12V093000, tied to a water seal leak causing complete headlight failure). Separately, and more seriously: a GM Technical Service Bulletin (PIC5692D) documents a brake pedal sticking issue that resulted in at least one 45 mph collision. This is a service bulletin rather than a formal recall, but the documented outcome is severe — ask your shop whether it applies to your car.
