On Interstate 95 heading south in North Carolina and hit a downpour, and I noticed the back end of the car started fishtailing. I slowed the car down to 50mph before the fishtailing stopped. The the AEB (Automatic Emergency Braking) alarm came on telling me to check the system. Once the rain lightened up and there was no running water on the road the AEB reset itself. I picked up speed to posted speed limit and no more fishtailing was noticed.

This happened a second time 8/23/20 on Route 29 in Virginia. Not a down pour but just enough rain to cause water to run across the road and it did the same thing fishtailing at 60mph had to slow to 50mph. The AEB did not alarm this time. In both cases the other cars on the road were still maintaining the speed limit. Tires on the car are Vredestein QUATRAC PRO 245/45-18 all tires have 5/32 of tread left.

This is the first car I have owned that has done this in rain.

When driving during heavy rain on the expressway the car begins to fishtail out of control. It forces the driver to drop their expressway speed to about 45 miles per hour. All the other traffic continues to pass by safely at speeds of 60 to 65 or more.This is a definite safety issue. When it began, I was nearly rear-ended by a semi when I was force to drive slowly in the right lane at only 40 to 45 in a 70 mph zone. If I dared to even try to go any faster the car would begin fishtailing. None of the other traffic had ANY issue going faster, and I NEVER experienced this in the 2013 Genesis I had previously. I have read of similar complaints and have been told that the car is reacting to its front sensor being 'blinded'. This is definitely a design flaw, and there does not appear to be ANY way to disable or inform the censor to ignore the present situation.
