Got a brand new 2017 LC and already have problems with the TPMS light after a new tire install. Light has been on since it had 350 miles on it. "Sad", as the current commander and chief might say. All sensors are reading but according to 2 dealerships that I visited they need to be reprogrammed. Both dealerships want to charge me to do it. I told them to forget it. My Gen 4 4Runner has lived with a piece of tape over the light for the past 3 years. This brand new car is starting its new life already with tape on its face. I wish I knew how to permanently turn off this system. I learned long ago how to check the air in my tires! Forgive me I'm ranting but I'm serious, I hate this thing.
You have a wife? If not, let me know if you don't and you can borrow mine for ten minutes. She will get that light off. Either that or the six o'clock news will be real interesting that night.
