Summary The 2009 Pontiac G3 has a range of potential issues, with some being more common than others. Engine-related problems such as EVAP leaks and O2 sensor failures can lead to check engine lights and reduced fuel economy. Transmission issues can cause rough shifting, while suspension problems can affect ride quality and handling. Electrical issues, such as window motor failures, can be inconvenient. Rust is a potential concern, especially in areas with harsh weather conditions. While some of these issues are relatively minor and inexpensive to fix, others can be more costly, potentially requiring extensive repairs.
