I purchased a new 2012 sonata 2.0 2 months ago. The TPMS light has come on 3 x's since purchase. As per bluelink I have taken in for service each time. I am last being told the light is still one but the tire pressure is @ 100%. Has anyone else experience this problem. I also owned a 09 sonata and the TPMS light would go on and off. I traded it for the 12 model.

 

That usually means a bad sensor at the wheel.

 

You are not alone.
I have a 2012 Sonata that I bought 10 months ago.
My sensor lit up and 2 days later went off and now it is back on.
I just had it reset 2 weeks ago when I had an oil change.
Now the sensor is lit up again.
I am sure it is faulty but that does not mean they can fix it.
I have not taken it back yet.
Let me know if you reolve this problem.
Thanks
