It is based on the Daewoo Kalos T200 and has been available under the Aveo name in the United States since the 2004 model year. Despite many assets, including its low price, the Aveo has been know to suffer from several technical problems that potential buyers should be aware of.

Engine Problems

Some of the most common problems with the Chevy Aveo involve the engine. Many of the earliest models that used Chevy's 1.4-litre and 1.6-litre four-cylinder engines experienced misfire due to issues with the seating of the valves. This problem could be fixed by replacing the faulty valves. Another engine problem common to early Aveos was leaking oil due to a faulty drain plug, but replacement plugs provide a quick and easy solution. However, severe engine damage can result from driving a vehicle with not enough oil.

Instrument Problems

Aveo owners have also reported problems relating to faulty instrumentation. Corrosion of the fuel level sender unit can result in an inaccurate reading on the fuel gauge. In cases where a cleaning does not fix the problem, a new sender may be needed, which requires draining the gas tank. In addition, minor electrical problems can lead to a check engine warning light, which may have to be reset by a technician. Problems with the oil pressure gauge have also been reported.

Other Issues

Several other issues have plagued the Chevy Aveo, though in smaller numbers. Faulty wheel bearings in the rear axle can cause a loud noise to come from the rear wheels. When the bearing is replaced, the bearing seal may need to be replaced as well. Some Aveos have also experienced transmission problems, with technicians recommending frequent checks of the transmission fluid. Other problems with the Aveo have stemmed from the throttle body, air conditioning system and indicators.

Overall Reliability

Since 2004, the Chevy Aveo has received generally poor ratings for its overall reliability. Other than the problems outlined here, a host of smaller issues have been reported that make the Aveo more costly and inconvenient to maintain and operate than other cars in its class. Consumer Guide Automotive gave the Aveo a 41 (out of 100) rating for the 2004 to 2008 model years, inclusive. General Motors has issued Aveo recalls for items as diverse as the transmission, electrical system, seat belts and airbags.

Repair Costs

With so many potential problems, the cost of common Aveo repairs is far ranging. Replacing drive belts may cost as little as £32. More common service, such as replacing the timing belt or water pump, can cost upward of £195 and £260, respectively. One of the more expensive repairs involves replacing head gaskets, which can surpass the £650 mark. Maintenance cost estimates for the 2010 Chevy Aveo fall within the £1,300 to £2,275 range over the car's first five years.
