2012 Kia Soul PInging

The squealing is normally belt slip and that is easy to fix with a can of Belt Conditioner spray.

The rest sounds like a weak battery and electrical issues which are best diagnosed by an auto electrician using a pro grade scan tool computer.

It's not the starter!

You did not mention when this pinging occurs (all the time? idle? lugging under load?). If it is in fact in the engine, it is most likely a timing issue which can get complicated because it could be caused by a problem with the distributor, timing chain or chain tensioner, one or more faulty engine sensors, etc.

However, there are other causes of this noise. Most pinging noises at idle or low RPMs are not usually in the motor itself but rather from rotating parts that periodically touch something, and often happen when something comes loose or is bent, bearings get worn, or something made it into the engine compartment that shouldn't be there (a tool, a rock, etc.). Typical examples are worn out HVAC fan, cooling fan or AC compressor clutch bearings; a cooling fan blade touching metal or a loose shield; and so on. If this is the case, you should try to locate exactly where this noise is coming from - a stethoscope from an auto parts store may help.

recheck your timing

this could be something called spark knock, make sure you are checking the oil also, if this is ok should take it into a garage, to make sure its not serious

This is because of the problem with the clutch. So you better consult a technician to fix it up

pinging noise low octane. mix gasoline half and half.half 87 and half 89.run it severals days if it still ping have it scan to check detonation sensor.a bad detonation sensor will also make car ping alot.

The pinging noise that you hear is detonation occuring in one or more of the cylinders. The dealer suggested to move to a higher octane inorder to prevent this because the higher the octane the higher the prevention of Detonation.

The Probable cause of the pinging, would be that you refilled with a bad batch of gasoline. Premium should be used in this vehicle no matter what. Due to the clearances of the heads and valves in the motor. And also due to the material used to make the cylinder heads, if severe detonation occures then the valves could be damaged.
