N VEHICLE LOW SPEED TIRE SCRUB CONDITION (SHUDDER FEEL)
Description: N Vehicles are designed to maximize dynamic steering performance. In normal Ackerman
steering geometry, the inner front tire turns more than the outer tire to help cornering in low-speed
situations, i.e., parking lot maneuvering or sharp U-turns. N vehicles have a steering geometry optimized
for performance driving. The N vehicle’s steering angle difference between the front wheels is reduced to
enhance cornering performance. While this helps in high performance driving conditions, it can cause a
higher level of tire side scrub that may create a slow shudder or vibration while turning at full steering lock.
The feel is similar to turning a 4WD vehicle on dry asphalt when locked in 4WD. This shudder or vibration
at parking lot speeds is normal, and no repairs should be performed.
Additionally, the summer tires on the N vehicles can make the shudder or vibration more pronounced in
cold ambient conditions.
Applicable Vehicles: All MY Elantra N (CN7N), Kona N (OSN), and Veloster N (JSN)
