I have an 07 kia sorento, 3.8 liter v-6. Dash lights dim while driving the vehicle. Is it my alternator?

Thanks,

Impossible to say from what little you told us. I’ll give you 2 choices; 1) Take it to an auto parts store and they will do an in-car test for free and tell you if the alternator is bad or if the battery is bad.

Or 2) Post back and answer my questions. Dim how? After a few minutes? Miles, Hours? What does the voltmeter on the car read when driving? Is the check engine light on. What are the codes? - the auto parts store will read those for free, too. Get the actual numbers in the format P1234
