Starting issues

Have a starting issue with my 2024 Tundra Platinum (approx. 500 miles) and was hoping someone else may have had this experience or some of you might have suggestions. Here is a quick background.
When I went to test drive the vehicle and pushed the start button, I got a message on the dash saying "not ready to start"... and it didn't. I pushed the button off and on about 5 times. Finally the sales rep got a technician out to us with a jumper pack. His thought was the battery was too low to activate the computer. Sure enough, once connected to the pack, it cranked. I purchased the truck and have since had this happen twice more. Fortunately, I didn't have to jump it, but it did take 3-4 attempts before it actually cranked. During those attempts, I got the same message.
I took the truck into the dealer's service department. They put their charger/testing unit onto the battery. The battery was low enough it took about 45 minutes of charging to bring it to 100%. Once there, they stated the battery tested fine and would not be able to replace it under warranty. They felt short, around town trips were not adequate to keep the battery sufficiently charged. Now I realize there is some draw on the battery all the time, with the computer on standby to communicate with the Toyota app, key fob, alarm, etc. However, I find it hard to believe that a battery that size isn't capable of providing adequate cranking power if sitting idle for more than 36- 48 hours ( which is the approximate down times for the two issues I had).
The service department pretty much did not offer any further explanation.
Has anyone had this happen with their Gen 3 Tundra? Could this be some unusual/abnormal power drainage?
Any help would be most appreciated.

 

I had considered that, just buying a new/better battery on my own. Thank you.

 

Shame on them for not replacing it without being asked, but not surprising. I'd upgrade the batt as well if they're giving you the typical run around, aint worth your time. Is this a hybrid?

 

Not a hybrid. And you are right Mattedfred, lesson learned. Honestly, we thought it was just from sitting on the lot for a few weeks. I took it home and did a slow charge overnight and figured I would be good to go. As you said Markus, not worth the time or aggrevation of getting stranded somewhere.

 

I would suspect an abnormal parasitic drain on the battery, if it's losing charge as quickly as you claim. If that's the case, it will do the same thing to a new battery.

 

Find another dealer that will take the time to correct the issue. I work for TMH and Toyota wants a bad battery to be fully charged for a min 10hrs, test it and if it fails repeat the test. My dealership usually just eats it because the customer comes first.
