Red triangle

the triangle is telling you, 'there are trouble codes, please read them'

 

You already mentioned the possible culprit "rebuilt battery new cells with 4 years warranty". You're going to be using that warranty a whole lot.....

The idea is your car will break down often enough for you to get frustrated and not call in for warranty anymore. A good question would be asking them what are the "new cells" they mentioned. They should show it to you, most likely all you'll see are old cells in your rebuilt used battery pack

 

Dealership in Okc said have to do with the light assembly level sensor installed in the back driverside tire?

They said it suppose to be like Lexus and Benz that the light beam curve follow when the car turn?? I never pay attention to this but Kudlow (the Liz) said is a life changer in rough environment like like AK??
