Cruise Control problems of the 2011 Jeep Liberty

While driving my 2011 Jeep Liberty with the cruise control set at 70mph on I-65 interstate coming out of gary indiana the tell-tales lit up and the car dropped out of cruise control and it took the car a few seconds to gain power again. This all started with the drivers door not unlocking with the remote. A diagnostics was run on the car and they said they couldn't find anything wrong, other than a rear sensor on the brake making the brake light come on. Doing an internet research the tipm sensor is the cause of most of these problems which Chrysler doesn't want to admit. This same issue was deemed not an issue a few years back by the NHTSA with the Liberty but deemed no good by the NHTSA for the Jeep cherokee and Dodge durango. This was a dangerous situation for me and my family. If I hadn't took action as quick as I did we would have been rear ended by a semi. I don't feel safe driving this SUV and this is my wife's car which she takes my son to school in. The NHTSA needs to do something about this issue now.
