Dealer has determined that the problem is with the positive battery terminal which is on order to be replaced. It was not in full contact with the battery due to a defect. My dealer has given me a 2024 Corolla Hatchback XSE as a loaner until the part comes and they can perform a full diagnosis of the vehicle.

 

Since the car is 2024 this might be of relevant but do you know if the warranty claim falls under the "Hybrid-Related Component Coverage" or "Hybrid Battery",

 

This is very similar to what I am currently going through. I got my CC Hybrid just before March and on April 1st got 6 emergency messages on my display. And yet everything was working fine otherwise. I got back into town the next day and took it in. Service spent the entire day diagnosing the issue and going through the codes, etc. Everything cleared and fine until 3 weeks later it happened again. Exact same issue. Back in the Toyota garage. Parts on order this time. They still don't have an exact idea what's triggering this.
With everyone's similar and repetitive issues, has anyone tried to file a lemon law claim? Or at least get either a refund or car exchange from the Toyota dealer?

 

Yes, Toyota service took care of all that and none have returned.

 

Wow. Good to know in case anyone gets the same issue! Thanks!

 

Sorry, no I don't know, I just know that its covered.

 

Thank goodness it’s covered. But what a nuisance!

 

Until I lost all electrical power and needed to be towed to my Toyota dealer, they never looked at the 12vdc battery in the back passenger area of the SUV. Instead they focused under the hood and could not replicate the problem. Finaly, they found that the positive cable was defective and needed to be replaced.

When the tech did see it, they thought that perhaps the tow-truck operator damaged it but when I reminded them that he could not access the battery and had to jump start the vehicle using the terminal in the fuse box under the hood, they dropped that line.

I've been golden since the battery cable was replaced.

 

Have your error codes been reset and cleared from the display?

 

I posted last month about my hybrid's similar situation. I brought it in a second time and after 7 days, they brought in techs with an entirely new differential unit! It's been 3 weeks since and seems fine.🤞

 

Hi John,

How've things been for you, since your issues last year?

 

I actually have this same exactly issues and currently my car in the workshop for repairs.. at first the service enter inform only battery 12v issues and need to replaced. Then when I come and picked up the car the problem still unsolved and now it’s been 3 days in service centre and they did find the problem but still need to wait for spare parts to come.. it’s better to towing if the problem persist and let them find the problem..
