Default Club Stumped On KO EX-10 Radio Issue - Help!

The equipment being used in the car includes:
KO Propo EX-10 Helios 75mhz (<4 hours of use)
KO 302f receiver (<4 hours of use)
Toro TS160 ESC (<2 hours of use)
Savox Servo

During a run, the car suddenly stopped and did not respond to input from the transmitter. After about 30 seconds, the steering started going crazy, and the throttle went to 100% a couple times as well. Now, the steering goes crazy whenever the car is turned on, however, turning the transmitter off reduces the movements to almost nothing.

So far I've tried a second set of crystals, as well as a 2nd (used) 302f receiver. Neither have yielded results.

Veterans at my local club initially suggested trying different crystals, and if not successful, a different receiver. Since neither has worked, the only other possibilities are the module, transmitter, esc, or that the second (used) receiver is broken with the same issue. No one at the club has any clue which possibility is most likely.

Please help me identify the problem! Thanks!

Tricky, seems to me there is something in the area causing radio interference.
Does the same thing happen if you go to a difference location?

Try different servo as well. I've seen in RC airplanes where a bad servo will cause other problems with the receiver. You may also want to unplug the esc and use a seperate battery to run the radio system if it's not a servo problem.

Yes, the same thing happens everywhere. Also the problem isn't effected by changing crystals.

That crossed my mind too about the servo, so I tried plugging in only the esc and still can't get it to receive any transmissions. And I've checked all the wires and connections on everything too, by the way.

Try a glitch buster/cap plugged into the receiver. The Savox servos are power hungry servos. You never know, might help. Oh, never mind, I see you tried without the servo. Does the radio have multiple model memory, did you try a different model on the radio?

I hate to be "that guy" but I think it's time for a new radio, mate.
