Speed Sensor problems of the 2007 Jeep Grand Cherokee

My wife was driving our vehicle down the road and not even 2 miles the vehicle would not let her go faster than 30 mph and the vehicle would not shift out of gear. The check engine light came on and we took it to get an obii scan. The code that was prompted was an esm malfunction or transmission speed sensor. I am having so much trouble finding a speed sensor that is available and high priced. The esm is not hardly available anywhere except at a dealer. I have been reading tonight online and there have been many cases of these problems happening with some more severe incidents. If so many people are having shifting, esm and speed sensor issues, shouldn't this issue be addressed. I am pretty sure this isn't the first issue or complaint. I have a 3 year old and a vehicle that was named a Smart buy by consumer guide automotive in 2006 and the redefining vehicle of Jeeps flagship is a hazard and unsafe for my family. I will not be recommending a Jeep of this year to anyone. I hope you take this incident with thoughtful consideration and start thinking about your consumers safety.

My wife was driving and just about to get onto the interstate and with no warning, she couldn't accelerate past 25-30mph. Luckily she was able to pull to the side of the road quickly without an issue and turned the car off, waited a minute and started the Jeep up again and was then able to accelerate. When talking to the dealer, they have never heard of this problem before. When Jeep was checked at a local dealer, they pulled error codes that pointed to the transmission speed sensor. Only about $700 to replace that with labor!! the sensors are all part of the circuit board and thus need to dismantle the transmission to replace the sensors. Then I get on this site and see all the complaints with the same issue. This weekend I'm going car searching to get rid of this thing.
