2013 Hyundai Elantra GLS PZEV 4dr Sedan (1.8L 4cyl 6A)
Without a doubt the noisiest and hardest riding car I've ever owned. On complaint,I was told perhaps nitrogen filled tires may be unbalanced.
Guess what? That was not the problem. I was told they could not duplicate the problem[s] and was signed off. I have 2400 miles and will trade in on another 'brand' ASAP!
Insulate main cabin better and improve suspension system
