2020 Camry XLE purchased, Oct 2019 has had the battery drain issue 3 times. Dealership finally replaced the battery in December 2019 the third time I took it to them. 10 months after they replaced the battery Oct 2020, I go out to the car and experienced the same problem! Smart key System malfunctioning / Battery dead. I was livid, this was the 4th time this has happen. I called 1-800 Toyota spoke to a Case Manager and Supervisor while vehicle was being towed to the dealership. I was told by the Case Manager that they had just release an update to correct this issue. I told him to call my dealership and ensure that they had the update and would perform the procedure on my car. He did and once I got to the dealership they informed me they would replace the battery and complete the DCM Reset and Firmware Update EL1934 0.8 86741-#####. Toyota and the Dealership says this will fix the Battery drain issue. I am hoping this works. If you are experiencing the same problem, make sure that 1-800 Toyota documents your case and make sure your dealership is aware of the update.
I had the same problem as everyone else. I joined this forum just so I could thank everyone for their input, especially tdock. When I took my used 2020 LE to the dealership yesterday. The "service coordinator" was not aware of the problem. He said he had heard of it on the Rav 4s, but not the Camrys. I was able to point out to him that this had been reported as a problem with both. He called his service manager who confirmed it was an issue with both models. It was very comforting to see the same Firmware Update EL1934 .8 printed on the service ticket as reported above.
I bought this car used as my final retirement car not expecting any problems. I traded in a 2003 LE with 210K miles, that I had replaced front brake pads, a starter, and front struts. This new car had been a rental/loaner from the dealership. It had remaining warranty, and I believe I paid a fair price. I suspect it had been driven most days, and may not have ever had the battery die. I feel confident now that the dead battery issue may be solved.
My heartfelt thanks to all who have taken the time to post their experiences.
