Same here. 2020 Camry TRD with 4800 miles.
First time the battery died was at around the 1500 mile mark. Car had been sitting for the weekend and on Monday it was dead.
Jump started and took it to the dealer. They found nothing wrong with it.
Happened again this weekend even though car had only been sitting for less than 48 hours. Unbelievable.
Good thing I bought a boost pack. Going to be needing it on a regular basis apparently.
Definitely wasn't the key fob as both fobs were in a different county than the car.
I've seen the TSB that essentially admits that the battery dies at about 48 hours. T-SB-0007-19
"A battery in a stored vehicle is subject to conditions that can reduce its performance and service life. These conditions include storage period, temperature, parasitic drain, and battery load. Because of these factors, battery inspection and maintenance are required in order to ensure proper operation and optimal battery life. As a matter of policy, Toyota does not provide battery warranty coverage for discharged and/or failed batteries due to lack of maintenance. It is the dealer’s responsibility to maintain the specified State-Of-Charge (SOC) of the vehicle’s battery while in stock and ensure proper SOC at delivery. To eliminate customer service concerns due to an undercharged battery during the first few weeks of ownership, ALL dealers should check battery SOC and recharge, if necessary, no more than 48 hours before to customer delivery. "
It's going back to the dealer again, but I'm pretty sure it's pointless to do so. Will see.
Have a funny feeling I'll be learning how to do parasitic draw testing very soon.
I see a lot of people post that they are having this issue but so far, no solutions. A quick read of the kbb website reviews
for these cars demonstrates pretty quick how big a problem this one is. Good job Toyota.
