First time went to get in my vehicle and the car would not even open, not even the trunk. Had been parked over night. The car was deader than a door nail. The Toyota dealer had a tow truck dispatched to me with a charge box. The charge box would not even crank the vehicle. Had to use his tow truck to jump the car took to Toyota they said it needed a software update. Did it seemed fine now fast forward several months later now when it cranks doesn't want to crank, dies then have to try again finally it crank. Took in today at dealer they tested battery said it's showing 100% testing so not the battery then they say the update didn't take back months ago so needs to be updated again . So now I've been shuttled home as it will take 2 plus hours. …
Started vehicle and went to back up. Car slammed into reverse and disply showed Drive start control malfunction. The service engine light came on. I removed the battery to reset the error message and the following dayi took it to the dealership. They checked it out and told me that they didnt find anything wrong with it since it wasnt displaying a service engine light. So i went home with it. The next day it did it again so i took it back to them while the condition was happening. Which insisted of the error message, serv eng light, gearshift indicator displaying drive and park at the same time. Also the door locks were continually locking and unlocking. They put a new water valve plus a neut switch assy and a new xmission lever in it and told me it was fixed. I picked it up and the next day it did it again. …
My 2020 Camry has been nothing but a problem and Toyota is noncompliant with helping me. The service recall for the fuel pump was fixed at Vaughn Toyota in Bastrop La .. a week later I still had the same issues. They refused to put another fuel pump on my car even thought the fuel pump had a one year warranty. I then took it to Landers in Little Rock and since I had "codes" I had to pay $180 diagnostic fee. Fast forward to now, still have the same crappy fuel pump. I took it to Ryburn Toyota and was told to replace the charcoal canister and vent valve . That was $1000. Problem not fixed. All my lights stay on, I often get a charging system error notification. It goes into reduced power mode. And has left me stranded numerous times on the side of the road. I want whatever is wrong with my car fixed. I have never owned a vehicle with this many problems. …
Battery was replaced 6 months ago due to being old, however, on Sept 19,2024 the car was completely dead after 4 days of no driving. Jumped by AAA and taken to dealer. Dealer reported on Sept 20 no issue with battery and no idea what could be draining th battery. Told me I don't drive it enough even though I just came back from a high mileage vacation and drove it for over 1 hour each way four days prior and two days before that. Told me I need to run for 30 min every other day even if it is just keep it idle in garage. Prior to this battery change I had no such issue letting it sit for days and not start. There seems to be an issue with this year of Camry that is going unaddressed by Toyota and needs a remedy other than drive your car more often as well as being told to buy a maintainer/charger to keep battery charged as told by the tech. …
