2023 corolla

Multiple problems with navigation not working since drove off lot, sounds like something dragging under car, diagnostic screen icons: red stop sign flashing, lights on vehicle diagram flashing, dinging sound constant when attempt to drive. Toyota dealer giving me run around. Same response every time: can't find anything wrong. 10,100 miles in two years. 36,000 mile warranty ends 11/21/25. Mileage dropped 50 mpg to 30 mpg highway. Dealership service manager told me to sell vehicle. Any suggestions? Anybody else having problems? Thanks

 

Is the engine oil level good? Are you the original owner?

 

I would suggest posting in a Corolla forum? But if there are that many lights on the dash and the dealer says nothing is wrong, find another dealer.

 

Yeah....if the dealer is giving you a hard time with all those issues...and lights on the dash. Different dealer time.

 

If a different dealer will not address your warranty issue I would contact Toyota Corporate.
