The Aveo was formerly known as the Kalos, a subcompact automobile built by GM Daewoo, a South Korean subsidiary of General Motors. The Aveo is based on Daewoo's latest small car platform and was originally styled by Giorgetto Giugiaro. For 2006, the Aveo, the smallest Chevy-badged car, underwent a number of changes that also gave the sedan a new face. Features in this economy car include advanced dual-stage frontal airbags with passenger sensing system, 13-inch or 14-inch steel wheels with bolt-on wheel covers on the base models or 14-inch alloy wheels on the top model, a retuned suspension with improved steering response and larger-diameter front stabilizer bar, tilting front seat headrests, revised interior fabrics, electronic throttle control and optional CD player. The Aveo comes in three trim lines, and available as a four-door sedan or a carryover five-door hatchback. All are powered by a 1.4-litre in-line four-cylinder, though the pre-facelift Aveo5 hatchback gets a weaker motor, and both come with a good five-speed manual that can be switched for an optional four-speed automatic. The hatchback was restyled for the 2008 model year after a brief hiatus, and remains different from the sedan. After the Sonic was introduced for 2012, the Aveo sedan continued to be offered as a fleet model.
Most problems with early models. Reports of key stuck in ignition stuck due to auto transmission problem, which requires solenoid valve replacement. Various reports of engine oil leaks, usually around oil pump gasket. Random reports of poor build quality, such as loose parts in exhaust system or recurring vibration problems with pedals.
