Purchased new a 2010 Hyundai Santa Fe, se. The problem that occurs randomly every few days is when accelerating slowly at around 20-30 mph and the transmission slips out of 2nd gear effectively putting the transmission in neutral for about 1 second, and then will hard shift into 3rd gear making a loud bang noise. It can feel as though I was rear ended. This problem has been occurring since new and has been taken to the dealer multiple times where there the problem could not be replicated. This is the same complaint as with about 10% of the 140 or so complaints on the NHTSA site for this year and model. There are at least 2 and possibly more TSB's that appear to address this problem (TSB-10-at-006, 12-at-012, 12-at-009-2). I will attempt to address the problem again with the dealer asking him to review these specific TSB's. After so many complaints about a very specific problem to a vital drivetrain component, it is time for Hyundai to take ownership of this problem and fix it! the consumer should not have to go through so much hassle for a widely known issue. How many more people have this problem and don't take the time to report it?.
