You mean the same dealer that said his 37" tires were the issue?Not hostile? And yeah encourage how to properly take the steps to test the voltage could have also been a great start also? Besides it’s all new and warranty hence the statement of take it to the dealer, so they can produce the good ol code and warranty him an aux and or both batteries that is all. But then again finding the dealers with people who actually care about the issues can be frustrating. Have yet to see tire size be an issue stop start doesn’t work and probably never will.
