the temperature gauge lights up even when it is not cold outside. at different times… sometimes after stopping at a stop light or just comes on. Then goes off ---

It seems that your engine is over heating and I am not sure why you think the outside temperature is relevant . I think you need to have a shop look at this but first check your coolant level . If you don’t know how find a friend that does before you destroy your engine. ---

the heater didn’t seem to work either when the temperature gauge would light up… gauge would come on after stopping at a stop light and starting up or would just come on even when it is cold outside ---

Explain what you mean by “temperature gauge would light up”. Have you checked the coolant level—when cold? ---

I would guess that is your overheating warning to shut it down immediately. **Have** you checked the coolant yet? ---

> [@MaryLawrence](#): > > the heater didn’t seem to work either when the temperature gauge would light up Uh oh. Heater not working due to low coolant due to: leak, neglect, head gasket. Sorry had to say it. Classic sign. Been there. ---

Get this to your dealer immediately, preferably with a tow, or at leas t a refilled radiator (properly done). You may need an engine replacement (under warranty). ---

Hyundai vehicles have a 10 year/100,000 mile powertrain warranty for the first owner. Repairing a coolant leak on the engine might be covered, a damaged engine caused by driving with insufficient coolant will likely be rejected.
