What stands out
Of the 7 model years of Chevrolet Aveo we track for engine problems, this one has the fewest owner complaints on file (11).
No new NHTSA engine complaint has been filed on this vehicle in over 16 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin provides information on identifying Non-GM Engine Calibrations for Gasoline Engines using the Tech 2 or GDS 2.

The failure pattern owners describe
The 2008 Chevrolet Aveo shows a clear pattern of throttle and sensor problems. Multiple owners report check engine code P2135 around 50,000–81,000 miles, manifesting as unwanted engine revving on startup, stalling, and sudden loss of acceleration. Owners who cleaned their throttle bodies found only temporary relief; the permanent fix involves replacing the throttle body assembly and position sensor, though one owner reported this warranty repair in 2010 didn't solve the issue.
More concerning are the fire reports. Owners describe engine fires starting spontaneously during freeway driving at 60+ mph, fires that continued burning 30–40 minutes after engine shutdown. One fire started after a low-speed deer strike; another occurred at 77,000 miles with no known cause. A separate complaint documents a catastrophic engine mount failure at low speed, where the engine dropped 8 inches, bent pulleys, ruptured the suspension, and ejected sparks and fire from under the hood—mechanics reported never seeing this failure mode before.
One owner experienced fan shroud rubbing against the radiator (addressed by manufacturer bulletin 08-06-02-002B), causing radiator perforation, overheating, loss of power, and steering on the freeway. A handful of owners also report unexplained loss of power and acceleration capability, one at 65 mph with smoke from the rear.
Early complaints include fume infiltration into the cabin at 550 miles; the dealer and manufacturer attributed this to environmental causes.

Failure modes owners describe
Throttle Position Sensor / Accelerator Pedal Voltage Correlation
Throttle or accelerator pedal sensor malfunction causing erratic idle, stalling, and loss of power. Code P2135 indicates voltage correlation failure between sensors.
When: 81,100–81,300 miles in one case; 52,973 miles in another; early (550 miles) in one case
Symptoms owners cite: engine revving on startup without pedal input; stalling after short drives; check engine light illumination; loss of ability to accelerate; independent deceleration while driving
Codes mentioned: P2135
Repairs/costs cited: Owners report throttle body cleaning as temporary fix; permanent solution requires throttle body assembly replacement with new throttle position sensor. One owner had throttle position sensor and accelerator pedal replaced under warranty in 2010 without resolution.
Fan Shroud Rubbing and Radiator Damage
Fan shroud contacts radiator during operation, causing radiator crack and fluid leak, leading to engine overheating, loss of power, and potential fire hazard.
When: Mileage not specified in complaint; occurred during 60–65 mph freeway driving
Symptoms owners cite: loss of acceleration capability; loss of steering power; heavy smoking after shutdown; engine overheating
Repairs/costs cited: Mechanic diagnosed fan shroud rubbing against radiator; radiator cracked and leaked, overheating melted and damaged multiple engine components.
Recalls/TSBs owners mention: Bulletin No. 08-06-02-002B issued addressing fan shroud rubbing
Engine Fire
Multiple reports of fires originating in or under the engine compartment, some during normal highway driving and one after minor collision impact.
When: 36,000 miles (after deer strike); 77,000 miles (cause unknown); mileage not stated in freeway fire case
Symptoms owners cite: smoke from engine compartment; smoke entering via air conditioning; flames engulfing vehicle; total vehicle destruction
Repairs/costs cited: Vehicles totaled; cause undetermined in some cases; one fire occurred post-collision (deer strike at 50 mph).
Catalytic Converter and Ignition Coil Failure
Catalytic converter failure with ignition coil malfunction causing loss of power and smoke from rear of vehicle.
When: 39,500 miles
Symptoms owners cite: loss of power at 65 mph; smoke from rear of vehicle
Repairs/costs cited: Technician diagnosed and replaced catalytic converter, ignition coil, and oxygen sensors.
Recalls/TSBs owners mention: Manufacturer notified of failure
Interior Fume Leakage and Window Condensation
Fumes entering cabin with moisture condensation on windows; dealer identified black soot on interior glass. Dealer and manufacturer attributed to environmental causes rather than manufacturing defect.
When: 550 miles (failure mileage); 1,937 miles (current mileage)
Symptoms owners cite: fumes leaking into passenger cabin; moisture on all interior windows; black soot on windows
Repairs/costs cited: Dealer wiped soot from windows; advised environmental attribution.
Recalls/TSBs owners mention: Manufacturer agreed with dealer's environmental attribution rather than accepting manufacturing defect responsibility
Engine Mount Failure
Engine dropped 8 inches from frame during low-speed driving, with sparks and fire ejecting from under hood. Engine pulleys pushed to side and suspension damaged by dropped engine.
When: Mileage not specified; occurred during 10 mph parking lot driving
Symptoms owners cite: loud explosion and rattle under hood; sparks and fire from engine compartment; engine dropped from frame; engine died
Repairs/costs cited: Engine dropped 3 inches from concrete; pulleys bent; all engine-attached components damaged; suspension destroyed on impact.
Unexplained Loss of Power and Shaking
Vehicle lost acceleration capability above 15 mph after left turn maneuver with preceding shaking sensation.
When: Mileage not stated
Symptoms owners cite: car shaking during left turn; inability to accelerate above 15 mph
Repairs/costs cited: No repair details provided.

A quarter of owners report trouble before 39,500; a quarter make it past 77,443. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
