Suspension Noise problems of the 2006 Jeep Commander

2006 Jeep Commander with 93000. I have had serviced multiple times over brakes and suspension. Brakes will just grind when trying to stop at times. Brakes have been replaced and problem still occurs. Every mechanic has said everything looks good. Had bigotires do 3 inspections on brakes and suspension and everything checked out! suspension- I have had services 3 times. All new parts have been put on front drivers side yet problem still persist. Popping noise and squeaking when turning and hitting speed bumps or pot holes and very noisy when backing up. Lighting has also started to go off and on! I believe something is wrong with the lighting. Sometimes when I turn them on they do not come on and once I turned them off and they did not turn off and made battery go dead but once jumps they were back to normal except my back tail light which I have tried having replaced multiple times does not work anymore and front passenger side head light has some major issues! also it is very hard to see when it rains even with brand new wipers there just wasn't much thought put into the Commanders! too many blind spots and also door handles on the inside easily break off!.

My wife reported a strange thumping sound from under the car. She said it began after dropping children at school and going over a speed bump at the school. Something she does every day. Upon inspection I found the driver side emergency brake cable was interfering with the rear universal joint on the driveshaft. The cable was kinked and being cut by the rotation of the driveshaft. There was also abrasion of the gas tank splash guard. I have no doubt if this happened at highway speed the cable would be cut in half and possibly wrap around the driveshaft causing the driver side emergency brake to apply and lock-up the wheel resulting in a rollover. The gas tank could also have been punctured if the cable was pulled by the driveshaft. Somehow the normal action of the vehicles suspension was able to place this cable in contact with the driveshaft. The rotation of the universal joint caught the cable pulling it into the rotating shaft. I consider this a class 1 defect that should be corrected with a model recall. Normally the emergency brake cable is routed off to the side and not directly over the differential. What were they thinking? Chrysler needs to devise a supplemental attaching point that will ensure the cables are not able to contact the driveshaft even under extreme off road driving. I have a full set of photos available upon request. I have ordered a new cable but the part number is on back order. This indicates there is a problem when the part cannot be stocked due to high demand. This cable should last the life of the vehicle without question. Nhtsa is there for the public. It exists on public taxes. It is not there to shield corporate mistakes and short cuts. I feel that NHTSA is not operating within the public trust if it allows defects to be ignored.
