Rear end locks up-anyone w similar problem 2018?

Hi. Looking for similar experience in 2018 Tacoma...automatic...20,000km, owned 1year...recently upon releasing handbrake (2wd mode) either vehicle goes a few feet and makes grinding noise in rear and locks up or won’t move when in gear w same problem. Happened 10 times. Releases after putting in park or reverse and re-engaging drive. Dealer can’t reproduce, no suggestions but imagine pulling into traffic or across train tracks and having it lock up. Dangerous, at least to me, but dealer not concerned. Can’t find TSB on this one. My non-mechanic hunch is one of rear brakes re-engages soon after forward motion.

 

Do you have any lift in the rear?

 

Haven't had that issue on my '18. I'm Box Stock, except for Ride Rite bags, and aftermarket trailer hitch.

 

Why would you use your handbrake just before crossing train tracks or pulling out into traffic?

 

Try driving in reverse and then hit the brakes aggressively.

 

I had this problem. It was caused by my rear lift tugging on my Parking brake cables. Happened when the rear axle flexed at all,

I think OP already traded it in.
