Many owners of 1995–1998, 2000–2007, 2009, and 2015 Avalons with automatic transmissions have expressed dissatisfaction with their vehicles’ inability to change in the correct gear at the appropriate time.

Many owners of 2014 Avalons have complained about experiencing unexpected acceleration as a typical issue.

Several owners have reported that their vehicles would make strange engine noises due to a damaged oil hose that caused engine oil to leak.
