HingeConstraint becomes unstable after a certain speed, can't figure out why

So, me and my friend were messing around with a RC car chassis I made that has improved handling. My friend wanted to make the car go faster, so he adjusted the max speed and got strange results.

For some strange reason, the front HingeConstraint motors start seperating from themselves after a certain speed, making the car unstable.

Video of the behavior

The front wheels are set up with a CylindricalConstraint attached to a separate mount block for the servos.

Then, the HingeConstraint motor is attached to the wheel itself from the mount block. This is the part that keeps glitching out and “seperating” from itself after a certain speed.

The rear wheels are set up in a similar fashion, however it uses a single CylindricalConstraint with no mount block. I’ve tried a lot of things, from adjusting the torque and acceleration to adjusting the mass of the mount blocks itself, but nothing has worked. I can’t seem to figure out why this is happening.

here to report this is still an issue that is severely affecting how we make our cars:

ive decided to make the model for the car public so you can take a closer look at what’s going on with it, it is a somewhat older version of the system but it still has the same issue as described above.

you will need a bigger testing ground for this as it can take some time for the car to speed up before the bug occurs. -simply pick up the remote and click on the car to test it
