2020 Toyota Camry le dead battery problems. Since I purchased the car on April 25 2020 I have had to purchase two new Toyota batteries from Toyota. The new batteries are 770 cca amps vs my oriinal battery which was only 563 ccawhich they do not make any more.yesterday I spoke with julie a customer care mananger fr. Om Toyota customer care and she said Toyota is getting alot of compaints about dead batteries from customers.when I asked her to do something about my spending over 300.oo dollars on two batteries because nowhere in their 608 page Toyota Camry manual does it tell you you have to close the windows and lock the doors or the battery will go dead. In fact my wife had asked the service manager at parks Toyota in deland Florida this exact question and he david carey saidy ou do not have to close windows or lock your doors.I have gone to the Toyota dealership 4 times spent over $300 dollars on 2 new batteriesand $250 on the correct test equipment to confirm the electrical problem of dead batteries was from the fact that I parked my car in my garage with the windows open and doors unlocked

Found service bulletin tsb00007-19 growing number of customer concerns about needing a new battery after 1 year. I brought my 2020 Toyota Camry into daytona Toyota for diagnosis of dead battery issue-technician took 8 hours and suggested I must have left the door or trunk open. Technician did say I should have received a new battery which is a new design, part #00544H6074770.this battery is rated at 770cca vs my battery which is rated at 560 cca. The new battery actually checks out at 990 cca! technician said it is the newly designed battery for the Toyota Camry and rav4 and would greatly reduce dead battery problem, however Toyota would not authorize a replacement. I have spent 2 full days chasing this problem at 2 dealerships and Toyota says it is my fault for leaving a door, hood, or trunk open-absurd! this is truly lousy service on a brand new vehicle with an underlying serious problem. For the immediate time I disconnect the battery cable when not going to use the care for 4 or 5 days. This vehicle needs a recall for battery or underlying drainage problem. Also see kelly blue book for many complaints about this.

When attempting to start the car from sitting just overnight, the dash will flash and click as if the battery is dead. The car won't start and has to be jumped. However when you have the car checked, it's not a problem with the battery. There is something draining the battery overnight that I haven't been able to diagnose. Nothing is plugged in and the lights are all turned off. The car is simply draining itself. There are only 6000 miles on the clock and no other outside factors that I can think of could be contributing to this issue. Also related to the electronics going crazy, is the rcd feature used while is reverse gear. After the car is jumped, that feature needs to be reset by a technician so the back up camera system works properly. This is very quickly becoming more then an annoyance.

Rodents appear to be attracted to the engine compartment where they are eating critical wiring. The wiring is associated with the fuel injection system. I had the vehicle repaired with the dealership, costing me $600. After returning the vehicle from these repairs at the dealership, I parked the vehicle at home and again rodents entered the engine compartment and chewed up additional wiring the very next day. The new repairs cost me and additional $600. The home is located in a rural area under a carport. I have lived in this home for seven years and have other cars parked adjacent to the automobile in question. No other vehicles, however, have had or are having problems with rodents. I will be trading in this vehicle immediately. I can not afford these costly repair bills.
