One problem related to transmission stuck in gear has been reported for the 1999 Hyundai Accent. The most recently reported issues are listed below.
The vehicle is a 1999 Hyundai Accent and I purchased it new. On July 2, 2004 I got in my car and turned it on. When I tried to put the car in reverse it would not move. The gear shift is stuck in 'park' and will not move unless the override switch is depressed. A technical service bulletin was issued by Hyundai for this exact issue (#99-40-017), so they already know that the problem exists. But, the dealerships I contacted in my area will not fix the problem because my car has a little over 80,000 miles and is no longer under warranty. I contacted Hyundai consumer affairs and they also said I would be responsible for paying for the repairs even though I never caused the problem.
