Loud knocking car stopped on highway got it towed home was able to start, a loud knocking started then it just stooped and it won't rotate

It sounds like your belt broke which not only ran the alternator, but also the waterpump. When the waterpump quit the engine got hot and siezed, I am sure that not having any oil helped the already dismal situation of your motor. I am confident that if you were to put a wrench on the front of the main engine pully that is attached to the crank shaft that it would not be willing to move. In short I would say it is time for a new engine.

I follow your story and found it very interesting. Looks like as the vehicle was driven decided to get relaxed. For what you done up to now you spent quite good amount of money with no results. Has at all passed from your mind whether all that cause by means of immobilizer activation or any fuel pump failure? The Knock Sensor want stop deadly the car. It causes misfiring,stalling etc.Hope this help, Good Luck.

Trust you mech on this one.

Unusual for the starter to fail on a one year old car.
You are having it towed to a dealer for warranty repairs, right ?

Have it towed and have it looked at by a professional.

Bang on the catalytic converter being careful not to get burnt and see if it's loose causing a rattle. Until you determind what the problem is don't drive the vehicle. The other possibility is that you may need an engine. If what you're hearing us a connecting rid knock.

Hello, This is a tough problem to find when there are no Diagnostics. I suspect the problem is due to a term called "Heat Sink"

What this term means is that the engine compartment is getting hotter when the engine is just shut off, than when it is running. When the Tow truck moved your car, wind passed by while the Tow truck moved your vehicle. This helped cool it off regardless of when the car was towed.

A lot of times the heat shields on the Catalytic converters are rusted off. In a pursuit vehicle, they could have been knocked off. This means someone needs to look under your car to see what is missing.

The electric components like the Ignition module, coil, Relays, and fuel lines can be overheating.

Try opening your hood when you park your car at home and then go out shortly afterwards and try starting the car. If it helps, you need to find the component that is overheating and replace any missing heat shields.

I hope my solution is very helpful. You can also get FREE scans at Autozne, Advance, and Oreillys autoparts when you get a Code light.

Drop your oil pan and remove the gasket, You will see your oil pump under your crank shaft. You will be able to remove it from here

Likely, you have a damaged engine bearing. When there is a problem there it will turn oil pressure light on because bearings keep the pressure inside the crankshaft...It may stop as the bearing overheats and binds, then loosens up a bit allowing a re-start when it gets cooler. Battery sounding dead is likely because the engine is locking up and too difficult for starter to turn.
At this point, it is not a do-it -yourself project ...either you need a lower end rebuild or engine replacement.

What kind of loud noise was it, like a clanking a banging or a knocking????
