If the front end was smushed, there may be a loose intercooler hose or broken intercooler. They've blown off or blown holes in them from time to time, and the 1.4 has no power of its own without the turbo's backup.
Wheel sensor codes could be related to transmission shift quality. As to why they're not registering - you may need to check the wiring or if the axles were replaced with some aftermarket junk that don't read correctly for the ABS sensors. Seen it before, but not on a Cruze.
Jerking at a stop is often the clutch packs in the transmission grabbing when they shouldn't be. Unfortunately a common issue with the 2013-2014 automatics; we don't know if they changed suppliers or what. Many have had them rebuilt under warranty, and it's only solved the issues for some.
The stock pads/rotors are junk. I had a 2016 Limited Cruze with 20K on it and it had pulsing/shaking brakes; my 2012 did about the same by the same mileage. Pick up some Centric Premium rotors and your choice of pads and enjoy a smooth-stopping Cruze. Make sure the rear drums are adjusted correctly - there's a thread on the forum here - even by 2016, the factory still didn't have it right, and I could feel the rear brakes on the rental start to grab when braking hard.
