I have been getting service engine soon light on the dashboard. Then shortly after my battery needed to be replaced and I thought that was the problem. Well the next weekend the light came on and now when I switch gears I get a loud thump and the car jumps really hard. I went to advanced auto parts with the service engine light still on they were able to retrieve codes and verify the transmission range sensor a circuit while in park/reverse/neurtal and drive. And they also retrieved the transmission control sensor. I am scared to drive my car now and I will not drive it till it gets fixed. I have had transmission problems for the longest time and I am scared this car will cause an accident. It is a very unsafe car. And I am concerned about the problem with the airbag not deploying due to many complaints. You need to do a recall on this car before someone gets badly injured or killed.
