The Three Most Frequent PROBLEM with Toyota Avalons

Toyota is getting ready to discontinue the Avalon, but there are plenty of used model years for potential buyers to own. Despite Toyota’s reputation for reliability, some of its vehicles still have flaws. That includes the Toyota Avalon with a couple of problems with its name. 

Some of the common problems of the Avalon include checking the engine light indicating a failed oxygen sensor.

What Problems Does The Toyota Avalon Have?

The Toyota Avalon has its own set of problems. According to RepairPal, the Avalon’s rear window sunshades tend to fail or emit a grinding noise. Over 200 owners have complained about this issue.

Moreover, like every other car on the market, the Avalon has examples of mechanical issues that could occur with high mileage. For instance, 171 owners complained about ignition coil failure after the 100,000-mile mark. 

Another issue that the Toyota Avalon has is a check engine light that illuminates following an oxygen sensor failure. That’s a common issue with passenger vehicles and definitely not unique to Toyota’s large, affordable luxury sedan. All in all, Avalon’s issues are manageable.

Does Toyota Avalon Have Transmission Problems?

While it’s infrequent, some Toyota Avalon owners report transmission issues at high mileage. For instance, nearly 100 owners said that their automatic transmissions fail to shift properly after reaching high odometer readings.

Most of the other most frequently reported issues involve sensors and failing components over hundreds of miles. Fortunately, transmission issues are not expected. Moreover, most model years of the Avalon go without mass complaints of transmission. 

Which Year Of The Avalon Should You Buy?

The Avalon model years with the most problems are the 2006, 2007, and 2008 models. Owners report oil leaks and loss of oil pressure without warning in their Avalon’s engine. So, the latest model years, like the 2021 and 2022 models, exhibit fewer problems.
