Dealer had for 3 weeks replacing the motor that only had 51,000 miles on it and was under warranty, had it for 2 weeks when all of a sudden it would not start. All lights come on put new battery in, new starter which is what the dealership diagnostics test showed was bad, and it still does the same thing. Just says to service stabilitrak and power steering. Can’t figure it out. Please help I need this thing to start.

 

Can't really diagnose that over the internet.
It needs hands on troubleshooting, which the dealer is obligated to do. Take it back.

 

It isn’t under warranty anymore and it doesn’t run

 

I realize that but they worked on your vehicle, changed your starter, and two weeks later it doesn't start. Odds are very likely the problem is related to the work they did. That seems common sense to me. They should at least check, and it doesn't hurt to try.

 

Yeah but I replaced the starter

 

then their diagnostic was wrong.
