Default Tire pressure indicator

I have a 2015 GS with 55,000 original miles, I have had it since new. My tire monitor inside the car went bland and I got the idiot light. I called Lexus and my advisor who I am not enamored with said it would cost $1200 to replace all of the batteries or $400-500 to just do one. My local tire place which is well respected said about $60 a tire for a generic. Any thoughts?

Thanks you

@BB11 - Yes, I have thoughts for you! Unless your Lexus service advisor is including 4 new tires in his pricing of $1,200 he gave you - - and one new tire for his pricing of $400-$500 - my thoughts about your Lexus service advisor is that he/she absolutely cannot be trusted.

Go to a Discount Tire store...

The battery is good for about 10 years and low males don't make different. I recommend usually the Lexus part. But in this case go with generic wat cat you of to 5 years not 10. Go for.

@BB11 Is your TMPS dash warning is flashing or solid? If the yellow TPMS light is solid, it just means you have one or more tires with low pressure. If the warning symbol is flashing, it means the sensors (most likely battery) need to be replaced:

You can get Denso compatible sensor for around $30-$40 which will have fresh batteries:
Amazon Amazon
(Note: I would buy these sensors and then take it to my local tire guy).

You can buy them from your Lexus dealer for around $70: https://www.mylparts.com/oem-parts/l...sor-4260730060 (you can then take it to your local tire shop and ask how much to install).

A good local tire shop will charge you the $50-$75 which typically includes removal of the old sensor, purchase of a new (likely aftermarket compatible) sensor and install of the new senor.

Note: I believe some folks have removed their old, existing sensors and changed out the battery - but its still just about the same amount of work to just replace the older sensor with a new one.

I had Discount Tire replace one of the TPMS sensors in my old '13 GS350 with a generic unit - you will not notice a difference. Skip the dealer for this one.

You can't replace the battery in a Denso TPMS sensor; instead, you must replace the entire sensor when the battery fails, as the battery is typically glued or potted inside the unit.

It's not impossible to replace the battery, but it's not worth the time to even try...

Thank you, I thought it was a tad high to say the least.

It started flashing then went solid. The next day my pressure readings worked but again stopped later in the day after driving for a bit. It started to flash and then went solid.

Replace the TPMS sensor with the same brand/type as the carmaker installed when the car was made - Denso brand made for Denso by Pacific Industrial.

I'm a not very handy older guy so this would not be for me but going to a shop and using a generic unit seems to be worth a try. I will visit my tire shop and see what they think of the Denslow unit and if they want to supply it or what they have. Thank you.

Just go to Discount Tire - they will have the proper TPMS in stock that matches what was originally installed, and they know how to program/sync it to your car's system.

Is this the sensor that Lexus used in the car when they built it?
