What Corolla owners report across recent generations
Owner summary2020–present (12th generation)
The most common complaint on the 2020 is a failed coolant bypass valve. Many NHTSA reports link it to an Engine Maintenance Required message that will not clear, and owners object to the repair cost for what they see as a small part. Some manual transmission owners describe clutch slave cylinder trouble. CarComplaints has few reports for this generation, led by a sour air conditioning smell, a failed A/C condenser and excessive road and engine noise. Recalls cover rear seat belts on some 2020 cars and a passenger occupant sensor on 2020–2021 cars that can keep the air bag from deploying. [1] [2]
2014–2019 (11th generation)
Owner trouble on this generation looks light. NHTSA complaints for the 2014 are spread across air bags, electrical items and a handful of transmission reports, without one dominant failure. CarComplaints ranks air conditioning that does not work properly, a radio that stops working and dashboard rattles as the top 2014 problems. The key recall covers 2011–2019 Corollas whose air bag control unit may malfunction in certain crashes and disable the air bags or seat belt pretensioners. [3] [4]
2009–2013 (10th generation)
The 2009 draws the most complaints of this generation. NHTSA reports focus on air bags, steering that wanders or loses assist at highway speed, and unintended acceleration, and 2009–2010 cars were part of the accelerator pedal and floor mat recalls. CarComplaints ranks excessive oil consumption first for 2009, followed by water pump failure and a loud engine noise. Other recalls cover passenger air bag inflators and a power window master switch that could short circuit and overheat. [5] [6]
