2009 Chevrolet Aveo cruise control problems
moderate 14 complaints filed with NHTSA · avg repair $600 · see cruise control across all vehicles →
Of the 7 model years of Chevrolet Aveo we track for cruise control problems, this one carries the most owner complaints on file — 14.
The failure pattern owners describe
Owners of 2009 Aveos describe sudden, uncontrolled changes in speed during normal driving. The most common complaint is unintended deceleration: the vehicle loses power on highways, slowing from 68 mph down to 38 mph in steps, with the accelerator becoming unresponsive despite the engine running. These events recur even after a 5–10 minute reset. Some dealers have blamed transmission failure (at 1,900 miles), loose wiring on acceleration sensors, or failed engine coils and cylinder heads; a few repairs stick, but several fail within days or months.
The flip side is unintended acceleration—the car speeds up on its own, sometimes violently, while the driver's foot is off the pedal. Rough idling, shuddering, and stalling at traffic lights also appear in the complaints.
Diagnostic codes P2101 and P2135 (throttle control) are documented in two reports, and a TSB is known to exist for the same model, but GM has declined to cover repairs outside the warranty period. In many instances, dealers cannot replicate the fault or find no codes at all, leaving owners stranded and uncertain. Multiple owners report visiting the dealer three or more times for the same symptom, with no resolution.
Failure modes owners describe
Unintended deceleration / loss of power
Vehicle loses power and slows down without driver input, sometimes repeatedly stepping down from highway speed (68 to 58 to 48 to 38 mph). Accelerator pedal becomes unresponsive. Can occur at any speed. Dealer diagnostics show no codes or cannot reproduce the issue.
When: 1,900 miles, 9,000 miles, 10,682 miles, 13,421 miles, 16,000 miles, ~78,000 miles, and others. Intermittent.
Symptoms owners cite: Vehicle decelerates without warning or driver input; Accelerator pedal does not respond when pressed; Engine continues to run but car loses propulsion; RPM gauge shows fluctuations or inappropriate response; No check engine light in many cases
Repairs/costs cited: One dealer recommended transmission replacement at 1,900 miles. Another identified loose wire on acceleration sensor; repaired but failure recurred at 4 months. Another mentioned 'part that allows fuel into engine.' One owner replaced MAF sensor without resolution.
Recalls/TSBs owners mention: GM advised recall decision based on mechanic reports of repeated fixes. One owner cited Technical Service Bulletin (TSB) with same model but GM declined to cover repair out of warranty. Referenced NHTSA #10034366.
Unintended acceleration
Vehicle accelerates on its own, sometimes violently, without driver depressing accelerator pedal or after driver has removed foot from pedal. Occurs both while idling and while driving. In one case, occurred while exiting driveway on incline; in another, at drive-thru with foot on brake.
When: 25,000 miles (worsened by 50,000 miles), 129,000 miles. Intermittent.
Symptoms owners cite: Car accelerates without driver pressing accelerator; Violent shuddering while idling; Accelerator pedal unresponsive to driver input; Vehicle revs up unexpectedly, sometimes to 35 mph or beyond; Brake pedal depression may not prevent acceleration
Repairs/costs cited: One dealer claimed behavior was normal. Independent mechanic unable to determine cause. No repairs recorded.
Rough idle, stalling, and surging
Vehicle idles roughly and shudders in Park or at traffic lights. Engine dies at stops (usually restarts). At all speeds, pressing gas produces no response, then vehicle surges forward and loses power. Shaking and lurching during acceleration.
When: 16,000 miles (failure), 17,000 miles (recurrence). Intermittent, ongoing.
Symptoms owners cite: Rough idle and violent shuddering; Engine stalls at traffic lights; No power response when accelerator depressed, then sudden lunge forward; RPM surges without driver input; Vehicle shakes while slowing; No trouble codes or check engine light
Repairs/costs cited: Dealer diagnosed and repaired failed engine coil and cylinder head, but failure recurred shortly after (1,000 miles later). One owner replaced MAF sensor without success.
Throttle / accelerator sensor failure and warning light
Check engine light illuminates while driving. Vehicle cannot be throttled beyond 10–15 mph or 2 mph. Diagnostic codes point to throttle control malfunction. One complaint references P2101/P2135 codes and a known TSB for the same model; GM declined repair due to out-of-warranty status.
When: 78,000 miles. ~36,000 miles (by complaint date). Mileage for narrative #12 not specified.
Symptoms owners cite: Check engine light comes on; Vehicle severely speed-limited (2–15 mph maximum); Accelerator pedal does not increase speed; Multiple failures over time
Repairs/costs cited: Narrative #11: Speed control sensor and accelerator pedal replaced; failure recurred numerous times. Narrative #12: Dealer stated 'part that allows fuel into engine' needed repair; third visit in 7 months.
Recalls/TSBs owners mention: TSB exists for same model (P2101/P2135). GM declined warranty repair for out-of-warranty vehicle.
Instrument cluster malfunction
Information cluster failure resulting in loss of throttle control and false acceleration signal (car accelerated to 4 RPM while idling at 1 RPM). Vehicle lost all power, then revved to 35 mph without warning. No check engine light despite malfunction.
When: Unknown; extended warranty had just expired.
Symptoms owners cite: Violent shuddering while idling; Sudden, unintended acceleration to 4 RPM; Loss of power on demand; False RPM readings or control signals; No check engine light
Repairs/costs cited: Dealer advised information cluster replacement, $700. Chevrolet does not cover this part outside warranty period.

Common questions
How serious is the cruise control problem on the 2009 Chevrolet Aveo?
It's a documented issue but not catastrophic. 14 complaints have been filed. Repairs average $600 and most owners catch it before it causes a breakdown.
At what mileage does the cruise control typically fail?
Across the 14 complaints that reported odometer mileage, most cruise control failures cluster between 16,000 and 78,000 miles, with the median around 40,000. A quarter of owners report trouble before 16,000; a quarter make it past 78,000. 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 $600 for cruise control 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.
Are there any recalls related to cruise control?
No active recalls currently cover cruise control issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
