The vehicle generated an error message "Plug In Charging System Malfunction" warning on the dash. The remedy is a Toyota T-SB-0021-21 which requires a software upgrade to fix the air fan sensor reading to the charging unit. This is only considered part of the 60 month/60,000 mile power train warranty despite it being part of the battery charging system which has a 150,000 mile warranty. It is also presumably caused by a software error Toyota has made. They should fix this at no cost to the customer, instead I was charged $215 plus tax.
The manufacturer has not corrected the recall in 10 months

Toyota issued a recall in July 2023 stating the the DC-DC conversion system may have been damaged in manufacture, potentially causing a short, and possibly leading to a fire if charged at less than 41 degrees. Toyota indicated that a fix would be available in the 4th quarter of 2023. We are nearing the end of the 4th quarter and fix is still not available. Living in upstate New York, nighttime temperatures frequently are less than 41 degrees. As a result I am reluctant to charge overnight. This defeats the purpose of a plug-in hybrid, resulting in higher fuel costs and excess vehicle pollution, not to mention additional anxiety due to potential fire! This is an unreasonable period of time to wait for such a potentially serious defect.
Car won't accelerate for about 1 to 2 seconds from stopped. Didn't have the issue before the 23TA01 recall performed at the Dealership.
