Open the full vehicle complaint log (all categories)Wheel lug nuts get swollen due to the material used causing problems when the wheels need to be removed. I was lucky to not be in an emergency situation needing to change a wheel out. This could have easily happened and I would have been unable to change a wheel on the side of the road. I went to Costco to get my tires changed and they refused to take the wheels off because the wheel lug nuts were ALL swollen and could cause issues on removal or/and installation. They were afraid of stripping the hardware during removal or being unable to torque to spec during installation. The replacement of the wheel lug nuts with parts that wont recreate the problem was about $90 and taking an extra day for the tire replacement appointment plus me replacing it on my own saved on labor.
