Can the sound be disconnected? Do they require batteries?

Not sure if/how you’d disconnect the sounds, but the batteries came inside (haven’t opened it up to see what kind they use). They’re my son’s favorite toys!

2 of the 4 just completly stopped making sound. Lights work and new batteries have not helped. Anyone have troubleshooting ideas?

When did you buy them? Maybe they are defective? I bought these for my Grandson a few months ago and his are all still working. If it’s only been a short time maybe reach out to the seller and see if they can be replaced?

my little one loves to spin the wheels. Can these be spun by hand or does the friction prevent that?

My kid also loves to spin wheels. And yes, you can spin them. Not all wheels have the friction mechanism, only two out of four wheels on each car. But even those with friction can be spun.
