Q: Vehicle stalling when stopping or turning.

Hi. As for the grinding, I believe you should have your brakes inspected. If the engine stalls and will not restart, that is the best time to see what the engine is missing to run properly. I find it strange that it happens only when you turn or brake. That could indicate loose wiring, bad connectors, or cracked sensors. There are many possibilities for this and some basic tests would need to be performed when the engine is not starting. Scan the computer for codes, check for spark, injector pulse, and fuel pressure. If you need further assistance, I recommend you have a certified technician, like one from YourMechanic, inspect the stalling issue and replace any failing components.
