Hi
My car is 2016 sonic. Yesterday I found the tire pressure signal light on from dashboard, and I felt it is hard to accelerate when peddling. But this morning I found the signal is off and seems the tires of the car is pumped , everything back to normal . I can tell it is a different feeling from yesterday. But I didn’t do anything but parked at garage all night. Is there any experienced can advise what’s going on here . Got really confused.by the way, the dashboard screen is not functional well yesterday cause only part of the screen shown .

 

tire pressure sensors would have no effect on acceleration. A flat tire would certainly be noticeable on acceleration through. Are you sure it was the tire pressure sensor and not something else?

 

You are right , just feel the tire is flat . I am sure it is the tire pressure sensor light .i double checked with the manual book but can’t find a answer
