| Description of the problem | I have been having intermittent transmission problems for a while now. I? Ve had the codes checked several times and by several people, and each one says that its a code for a faulty automatic transmission temperature sensor. It causes very hard and unpredictable shifting. We? Ve had to stop driving it all together because of safety concerns due to the fact that the last time i drove it i had my 11 year old daughter in the car with me and the car would not shift into the proper gear while going through a busy intersection, and we were almost t-boned by a large suv, the impact would have been on the passenger side where my daughter was and i have refused to drive or allow the car to be driven since. I have found a very large number of complaints for this same issue on several sites online, most of which i have come across on a sonata forum. This is a known issue by the manufacturer. This is not something that is uncommon among these cars, but it is extremely dangerous, and the fact that there has not been a recall issued to correct it is, in my opinion, reckless and irresponsible. We put our lives, and the lives of our family and loved ones, in these cars because we trusted this company/manufacturer to keep us safe, and they have failed and continue to fail by not addressing this issue properly. |
