What 2021 Toyota Avalon owners say
Air bags
My vehicle is under Safety Recall 23V865 (Toyota dealer reference 23TB15) due to potentially defective Occupant Classification System (OCS) sensors in the front passenger seat, which may prevent the airbag from deploying properly. The recall was issued in December 2023, and as of August 2025, there is still no available remedy. Toyota originally estimated a fix by Q3 of 2024, but it is now overdue. This unresolved issue puts passenger safety at risk in the event of a crash. I have contacted dealerships and checked for updates, but no solution has been provided. I believe this delay is unacceptable for a critical safety defect and request NHTSA to investigate the remedy timeline and pressure Toyota to provide a fix or alternative solution.

Driver assistance
The Rear Cross Traffic Warning signal is installed behind rear head rest, which muffles the alert sound to barely audible, even when setting is on high. Vanandergriff Toyota dealership in Arlington, Tx., verified this information to me after bringing my car in four times for service because I was not being warned of persons and vehicles passing behind me. I've called Toyota's home office and told nothing can be done, as it was installed this way, although I am still asking they remove muffling material or change location of warning equipment. It is very dangerous, as persons and cars are not always visible due to parking location or blind spots. This should be a recall item. All other warning signals on front of car work properly. I was told by company representative to just use drive-through parking! Consumer contacted Toyota customer service and the dealership in Arlington, Tx. …

Did not fix the problem. Have been informed that I need a wiring harness! About to spend a total of 400.00
