While in motion vehicle check engine light will come on with the following messages. Stabilitrack off, traction control off, engine power reduced. Car will not accelerate above 40 mph. Car will slightly shake while this happens. Car will some times also shut off completely and not restart until codes have been cleared. This has happened on several occasions starting in February 2017. I have been told it needs a new wiring harness, new powertrain control module, new fuse box due to water intrusion, water is stated to come from cracked windshield but windshield has been replaced before and problem persisted. Fuse box has been replaced. Pcm and ignition switch have both been replaced. Gives code p1682 which is ignition 1 switch circuit 2 code. Two document #s have shown up when running diagnostic check (4583190 and 4184289).
