I have a 2015 Kia Soul with about 116,000 miles on it that recently lost two cylinders. I plugged in my scan tool and it reads that cylinders three and four are misfiring, but I can't determine any engine damage. The car shakes so bad it vibrates the entire car but there's no knocking or metallic banging sound. The dealership I sent it to 3 weeks ago is stonewalling me and won't return my phone calls and won't answer the phone when I pick up. What can I do?
go there , pick it up, and drive it to another shop

There's a big difference between dead cylinders and cylinders that are badly misfiring. If you have a dead cylinder on a 4-cylinder engine, the normal cylinder firing every 90⁰ rotation of the crankshaft doesn't happen; you would need to complete a 180⁰ rotation for another cylinder to fire, and there won't be enough fuel to get through 180⁰ of rotation. This will outright stall the engine. If two cylinders were dead, it would further drag out the situation; 270⁰ of rotation of the crankshaft would be required before another cylinder can fire.
My old Pontiac has a V8, and I noticed randomly that the engine seemed to be misfiring and I smelled gas when it was cold and the hood was open. Once it warmed up, it was fine. Turned out a couple spark plugs had worked slightly loose probably 5 months after I had put them in.
