NHTSA's VIN data lists these trims for the 2020 Avalon. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 10 complaints with NHTSA about the 2020 Avalon. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 4 recall campaigns for the 2020 Avalon over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Avalon, Avalon Hybrid, Corolla, Highlander, Highlander Hybrid, RAV4, RAV4 Hybrid, Lexus ES350, Lexus RX350, Lexus RX450H, 2021 Sienna Hybrid, Lexus ES250, 2020-2022 Camry, Camry Hybrid, and ES300H vehicles. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.
Risk: An air bag that does not deploy during a crash increases the risk of injury.
Remedy: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 23TB15/23TA15 Lexus 23LB03/23LA03.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles. Breakaway pins within the steering column, designed to absorb energy and reduce injury during a crash, could have been damaged during production, possibly affecting the performance of the driver's air bag in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
Risk: In the event of a crash, an air bag that does not perform as designed can increase the risk of injury.
Remedy: Toyota will notify owners, and dealers will replace the steering column, free of charge. The recall began December 18, 2020. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 20TB17/20TA17.
Risk: If the fuel pump fails, the engine can stall while driving, increasing the risk of a crash.
Remedy: Toyota will notify owners, and dealers will replace the fuel pump assembly with an improved one, free of charge. Owners of specific models were notified that remedy parts were available starting January 21, 2021. Owners of other models will be notified as remedy parts become available. Remedy parts should be available for all affected vehicles by late March 2021. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus customer service at 1-800-255-3987. Note: This recall is an expansion of recall 20V-012. Toyota's number for this recall is 20TA02. Lexus' number for this recall is 20LA01.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020 Toyota Avalon Hybrid, Camry, Camry Hybrid and Lexus ES300h and 2019-2020 RAV4 and RAV4 Hybrid vehicles equipped with 2.5L 4-Cylinder engines. Porosity in the engine castings may result in cracks than can allow coolant to leak internally and/or externally.
Risk: A coolant leak can cause the engine to overheat and cause a vehicle stall in conventional gasoline vehicles, increasing the risk of a crash. Additionally, for all involved vehicles, the engine may get damaged mechanically, possibly resulting in an engine oil leak, increasing the risk of a fire.
Remedy: Toyota will notify owners, and dealers will inspect and replace the engine including the engine block, as necessary, free of charge. The recall began April 3, 2020. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus at 1-800-255-3987. Toyota's number for this recall is 20TA04. Lexus' number for this recall is 20LA02.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
