Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey, our reliability history charts give you a rundown on how used vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system.
The Reliability score is based on our latest subscriber survey of 2017 Toyota Avalon owners. The owner comments describe problems respondents experienced with this vehicle.

"Right front fender kept popping out of place over a year ago. Simples putting it back into place failed, requiring a $1900 repair. We think that the car is so low to the ground that the underbody hits the concrete parking barrier meant to simply stop the front tires, thereby causing the right fender issue. The low height, high pressure tires are not a favorite of ours"
