5.7 Hemi
Need you guys help ASAP. I recently got a 2012 5.7 hemi in my divorce. Was not told about anything that might be wrong with it. For the past month she dies on me while driving. If I turn a corner or even go over a bump, she dies. Up until a week ago I was able to put her in park and start her back up but now nothing. I was told by son that it was the fuel pump, so I replaced that. I did find that the fuel vapor recirculation valve was broken and I can't find a replacement for that. I have found in this past week alot more problems. Passenger windows won't go down but will lock the doors, driver window sometimes won't work and can't lock the doors. Back is fine. A/C won't work but heater does but doesn't blow hard. That's just the tip of the iceberg. I really need your guys help to get me back on the road. Oh and I can't afford a professional shop so I am doing this myself. Oh and the codes I'm getting are P0562, P2096, 0171,0174, No fuse. Brand new Battery. starter, ignition, alternator all tested was told they are good.

P0562 could be a bad voltage regulator, but your first step should be to remove all main power and ground wires, clean the contacts and contact points, and replace any wires that look bad or have sharp kinks.

P2096 could be a bad O2 sensor, but again check contacts first and clean everything up.

P0171 and 0174 could be a bad MAF or MAP, loose exhaust system, check clamps on hose connections, could be one or more bad fuel injectors +consider this last) or the fuel pressure regulator is bad.

Kind of thinking you have electrical contact issues here, get it all cleaned up first and be sure contacts are tight, the issue on turns seems to point to something loose. Do you know vehicle history? Could it have been in a flood. If you don't know, a tell tale sign is a lot of rust on metal up under the dashboard.
