2019 Toyota Avalon

2019 Toyota Avalon XSE with 41,400 miles. Complete failure of the Climate Control Panel. No buttons or lights would work, resulting in lack of any fan, heat, air conditioning, window defroster, mirror defroster or seat heat. Found no fuses blown. On one occasion since then both seat heat lights came on indicating full heat but did not produce any heat. Two days later Panel began to work normally for a 1 hour drive. Later this day there was another complete failure of the same panel. Took car to dealership the next day and panel functioned normally enroute. When dealership diagnosed the problem the Climate Control Panel had failed again and the problem could not be duplicated. No trouble codes were stored in the system. They performed a master reset of the system thinking an update may have been corrupt. Panel worked when leaving the dealership later this day. The next morning the Panel initially did not work, but 20 minutes into a 1 hour drive it started working normally. That evening the Panel failed again on vehicle startup and has not worked since. Took it back to the dealership this morning and did not turn vehicle off, thinking the failure might show up in the car’s system until the service advisor could drive it to a maintenance bay. After 3 hours the problem could not be diagnosed. The lead mechanic contacted Toyota corporate to inquire if this problem has been encountered previously and for a possible solution. Overall this may not be a safety issue warranting any further action. However, if the windows or mirrors were to fog up, there would be no defroster capability for either of these. In this situation it could quickly become a dangerous situation while the vehicle is moving. This should be investigated further.

The sunroof of my 2019 Toyota Avalon is defective. It is available for inspection upon request. My safety, as well as the safety of my passengers, has been put at risk. My problem has been confirmed by Sheehy Toyota of Fredericksburg. No warning lamps or messages to indicate sunroof problem. The driver side of my sunroof keeps clogging. I first took my vehicle to Toyota Sheehy of Fredericksburg on 1/3/2023. Sunroof tray was found to have a buildup of organic detritus, causing drains of sunroof tray to be clogged and allowing rainwater to spill over into interior. Sheehy technician cleared the sunroof tray and drains of organic material. Drains were now flowing properly. Technician claimed that sunroof would not have to be drained for at least two years. There was standing water and a heavy mildew smell in the car. Sheehy refused to clean/drain carpet of water. I took it to a detailer and had the detailer vacuum and clean the carpet. Less than a month later, I started experiencing the same issues -- wet carpeting on the floorboard. I took my vehicle to Sheehy Toyota of Fredericksburg on 2/7/2023. Technician told me that the driver side of the sunroof was clogged. Technician claimed that he fixed the clogged drain of the sunroof. Technician suggested that my sunroof got clogged because I have only driven my car 140 miles this month. Not a rational explanation. He recommended that I replace the carpet due to mold concerns. Why would I replace the carpet if there is a strong possibility of having wet carpet every few weeks? Technician insists that wet floor is not coming from any source other than the sunroof. I suspect that my sunroof is defective. I should not have to worry about wet carpet in my car everyday that we experience rainshowers. Sheehy Toyota insists that nothing is wrong with the structural integrity of the sunroof and that external factors are to blame.

After starting car, from being parked in parking garage from 8am-5pm, the Pre Collision warning system light turned on. Vehicle currently has 20k miles on the odometer. There are numerous records in the car's onboard history of this device failing during car startup. Drove home, started next day with no incident. System is unreliable. According to the Infotainment system, the car seems to report the failure every few months.
