Bought the Santa Fe used with 96046 miles on it. Shortly after buying it it began making a loud banging noise in the rear end when first starting out especially starting out on an upgrade. Also makes the noise when backing up in wet grass or muddy conditions. Sometimes sounds like the whole back end is going to fall off the car. Unfortunately no warranty. There are plenty of complaints regarding the transmission. Needs addressed before someone gets hurt.
