2013 Chevrolet Suburban - Electrical issues

Total electrical goes out no power anywhere when driving all locks go up and down I have contacted state attorney , Dmv, as well as corporate they are trying to close case and advise dealer will not even trade my truck pick to them had for 87 days

What are you trying to accomplish?
Sounds like you bought a 5 year old car, 3 months ago, that has now developed an electrical problem.
Was it purchased “As is, No Warranty”?
If the used car lot offered a warranty, the warranty is probably highly limited.
What has a mechanic told you the source of the problem?
