| Description of the problem | The first time i thought something strange was going on with my new car (purchased with 16,000 miles on it) at the 18,000 mile mark. . The car was stuck in 4th gear and would not change gears with the auto stick or with the pedals. I stopped the car and tried to pull out in traffic but had no power. I pulled over asap and turned the car off (rebooted the car) and everything worked again. On the dec 17th,2011, (3 weeks later) i was pulling out of a friends house at 10pm and everything seem normal. However, as the car got to about 15mph the tach raced over to 5,000 rpms and then i heard a loud slam and the car shot forward. I recalled the last time the car acted strange so i checked to see what gear it was in and sure enough it was again in 4th gear. When i tried to change gears it would not change gears just as before. I pulled over and tired to reboot the car again, but this time it did not fix itself. I had to drive 30miles home, so i got on the interstate and headed home. The tach raced a few times, but because the car stayed in 4th gear i make it home safely. When i got home i discover the reverse was gone out as well. Now for the good news, i researched the issues one this and a few other site and discover i was not the only one with this problem. I took my car to the dealer this morning and asked for a new transmission. The service tech got me a loaner in less than 30mins i was on my way. Same car and color. I got a call from the dealer a couple of hours later saying they were going to replace the entire transmission. While and i not happy that my new car required a new transmission after only 3500 miles of me driving it and under 20,000 total miles, i am very happy how the dealer handled the entire issue. Hats off to eastern shore h of daphne, ala and thank god i got the 100,000 extended warranty. Will up date when i get my car back in 5 days. |
