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. …
Cruise control stopped working while driving interstate speed. Would not work and all lights on dashboard came on . Proceeded to Nearest dealership and was informed that I needed a brake switch. Did not fix the problem. Have been informed that I need a wiring harness! About to spend a total of 400.00
This incident has happened twice in three years. Hence it is a very rare occurrence. Both times involved the same events. Cruise control was on. I was traveling in the left lane of the interstate highway, approaching an 18-wheel truck which was in the right lane. When I was approximately 50 feet from the rear of the truck, the truck began to enter my lane. I suspect I was in the trucker's blind spot. My car did not sense the truck. The cruise control did not disengage. The brakes did not engage. But the MOST troublesome was that the car did not respond to my pressing on the brake pedal. I had to press 4 or 5 times before the cruise control would disengage and the brakes engage. Since I was traveling approximately 70 mph, the distance between my car and the truck (each time) closed rapidly. In the first instance, the truck tire hit my right front fender. …
After starting to accelerate from a stop light ,the Dashboard had a warning message that the accelerator and brake pedals were pressed simultaneously. The acceleration stopped and the car slowed automatically. After a few seconds the warning indicator went away and the car could accelerate. The cars behind my auto had to stop suddenly. At the time. I though that I might have hit both petals at the same time. When it happened again I opened an incident report with Toyota. Incident opened on 07-19-25 Case # 250719000440. The Toyota rep told me it should be take to a Toyota dealer to diagmose any error codes.The next time the same problem occured I took it to my Toyota dealer and was told there were no error codes to indicate a problem. …

05/04/2025 First of all, we love our Avalon. However, for the last 6 months or so, water is getting in the car and ends up soaking the carpet on the left front floorboard carpet. We have checked everything we can think of to find the source of the leak but was uneasily. We had to have some scratches fixed and took the car to a body shop to see if they could find the source of the leak. They sprayed water on the sunroof for about an hour but no water leaked inside. We have also taken the car to the local Toyota Dealership (Sheehy Toyota in the Fredericksburg area, they could not find the source of the leak. It rained here (Fredericksburg, VA last night and the left front floorboard was soaked. I need help finding the source of the leak(s) so we can continue enjoying our Avalon.

Toyota issued recall 15V728, regarding the pcs system on our Avalon. That was last November, 2015. Toyota has failed to provide a fix, and we have been without this very expensive important safety feature for over half a year. Toyota's notice stated that if "Toyota has failed or is unable to remedy within a reasonable time, you May submit a complaint to the administrator , national highway traffic safety administration. " I am herein registering that complaint, and request that the NHTSA require Toyota to refund to owners of the affected vehicles the value of the feature we have been deprived of for over half a year. It does not appear that Toyota is going to be able to correct this safety defect in the indefinite future, so Toyota's failure to provide this feature we paid dearly for is bordering on fraud. …
