Subaru owners most frequently report excessive oil consumption and transmission problems with their vehicles, according to car repair statistics site CarComplaints.com. Critics and owners also find that Subaru's entry-level vehicles offer too little power as compared to similar cars produced by competitors.
While Subaru vehicles overall have a good reputation for safety and reliability, oil consumption problems have been frequently reported for many models built since 2010. The most affected model is the 2011 Subaru Forester, according to data from CarComplaints.com. The cause of this issue is not clear, but in some cases can lead to engine failure due to inadequate oil.
Transmission issues are common among Subaru vehicles built in the mid-2000s with manual transmissions. Premature clutch failure is the most common such problem reported by owners, though some also report complete transmission failures as well.
Reviewers of recent Subaru models as of June 2015 often find that Subaru's cars lack acceleration capability with the company's base engines, especially at highway speed. This complaint is most often leveled at the Subaru Impreza sedan, XV Crosstrek crossover and Outback wagon. Some owners also find the continuously-variable transmission used on some Subaru models can hesitate and prevent the car from accelerating responsively when the gas pedal is pressed. This problem has been most commonly reported on the 2014 Forester.
