Known issues
-
The 2.4L Ecotec four-cylinder is prone to excessive oil consumption from worn piston rings and a poor PCV design, which can starve and stretch the timing chain and lead to stalling or engine failure; GM issued a service bulletin to replace pistons and rings.
widespread · 729 NHTSA complaints · typically 50k–120k miles · engine
-
Timing chain wear and stretch on the 2.4L engine, often a downstream effect of low oil from the consumption problem, can trigger check-engine codes, rattle on start-up and, if ignored, catastrophic engine damage.
commonly reported · typically 60k–130k miles · engine
-
Windshield wiper and visibility failures recur across the first generation, with wipers stopping mid-operation in rain; a common safety-related complaint especially on 2010-2016 models.
commonly reported · 200 NHTSA complaints · electrical
-
The 6-speed automatic draws complaints of hard shifting, jerking and hesitation, most prominent on early 2010-2012 models.

Depreciation
Move your cursor along the line to see the estimated value for any year.
This listing sits above the typical depreciation curve. Common for heavily-optioned cars and for 2021-2023 model years (pandemic-era pricing); the curve is anchored at base MSRP, which excludes options.
Curve anchored at the entry-trim base MSRP ($25,560). Higher trims started higher (up to $28,510), and options added more.
The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
