I was informed after 3 hours at the Hyundai dealer that my 2014 Hyundai Elantra with less than 4,500 miles is gonna need a new transmission. The issue is that when I back up the driveway the entire car shakes and makes a grumbling sound. The tech said that the car will be fine for a beach trip next week, but as soon as I get back they need to install the new (not rebuilt) transmission. This seems like such bullshit that a car with less than 10,000 miles would have this severe of a problem.
