I recently installed a Lithiumhub Emergency Start on my 2024 Lexus RX350h for peace of mind. Installation was easy and it works as described. I am due for my 10000 mile checkup in April and was wondering if I should deinstall prior to dropping off at the dealer. I am trying to avoid having future dealer issues with warranty if they object to the battery protection.

 

Without a doubt remove it. Dealer will call that a modification and it may end up in your repair records.

 

I left it in and they have never commented on it. I've had it serviced 5 times since installing it.

 

As I mentioned previously, the dealer checked our battery health during that rear camera recall, without me asking.

They didn't note anything about the monitor on the paperwork, but the service writer mentioned that it could drain the battery.

I told him "I don't think it does any more than the LED on the dash, and I'm monitoring the voltage and SOC to make sure!"
