In our 2010 rear center seat the belt will only come out a few inches and then stop like that's the end of it. It just got really cold here. We can't have our entire family go in the car now. This is a serous safety issue. Will hopefully call dealer tomorrow
We have not seen ours freezing up. [obviously not saying that such is not possible] I wonder if you parked the vehicle in a heated garage for a couple hours, if that would unfreeze the mechanism.
The seat belts are typically covered under mfg warranty forever as the manufacturers do not want to have a lawsuit on their hands. Take it to a Toyota dealer they should fix it for free. Good luck.
Just went on a 8 hour trip and had to let the car warm up for 30 min before seat belt would come out more than an inch
