What in the world happened? TMPS related...

Today I was driving and out of nowhere, the Service Tire Monitor System came on. When I went to check the tire pressure screen, both of the rear tires no longer reads any pressure but the front ones are fine. What in the world????

Sorry to hear about the concern you are experiencing. On pages 10-59 to 10-63 in your owners manual help with a self diagnosis first. You may want to check into doing the TPMS Sensor Matching Process on 10-63. If this doesn’t fix the issue, the best thing for you to do is to get in touch with your local dealership and get it diagnosed. You may even be under a warranty still. If you want to PM me your VIN I can check to see if there are any applicable warranties to address your concern. I look forward to hearing from you!
