While driving on the interstate at approximately 71mph, hit a bump vehicle started to violently shake. Slowing down did not fix the issue. I had to pull over and stop. Very scary feeling. Both batteries died out at approximately 39,000, first the main battery, then the auxiliary battery. Noise coming from behind the glove box when the vehicle is powered on or not. Clunking noise when taking off from a stop, or first take off. (dealer stated it was normal (yeah right)) passenger visor broken. Hardtop leaking in center front, causing the rearview mirror to ruin. (has been looked at by the dealership numerous times. Air conditioning when driving a long distance will sometimes blow out hot air on the passenger side. Coolant drained dye put in to detect leaks, no leaks. Still happening floorboards get extremely hot at times it feels like the heater is on.
Rear lower control arm mount/ track bar mount failed. Appeared to have only half of the mount welded in a manufacturing defect. Quality control issue.*dt consumer heard a clunk/knocking noise coming from the rear of the vehicle. The right rear lower control arm bracket had separated from the frame. Manufacturer stated that the cause of the separation was that the right rear lower control arm bracket inboard weld was completely off-seam. Manufacturer repaired vehicle on 2/5/2020.
Body: water leak from hardtop (right front passenger) and (front center - where hardtop meets windshield pillar). Multiple attempts to correct (replaced all seals) and there is still a leak from front center (where hardtop meets windshield pillar). Suspension: loud 'clunk' or 'thump' coming from rear when accelerating from both a dead stop and while moving at less than (5) MPH and accelerating.
Jeep jlu began "death wobble" at 70mph while on I-485 (speed limit is 70). Had to slow down to 40mph to get it to stop, which almost caused a crash with vehicles behind/beside me slowing to match. Since then, "death wobble" has occurred 2-3 times per week on various roads. Speeds 50-70. I now have 3 roads where I can replicate it and will be going back to the dealership. Was told months ago by dealership "it's not death wobble; sometimes stuff gets stuck in the wheels and makes a clunking sound." sorry, not sorry. Entire jeep front end felt like it was on hydraulics.
I have had numerous issue with being able to steer the vehicle strait. The jeep is all over the place. I had to hold the wheel at a angle for the jeep to steer strait. I was hearing a loud clunking noise when driving at low speeds maybe 10-15mph and was told the rear differential had to be replaced.
I entered a parking space and was not within the lines. I backed up about 2 feet and felt a sudden stop and 'clunk.' I could not move the shifter at all. The dash display said 'park lock.' it instructed me to turn the car of and then put it back in gear. After 3 attempts to do that (I may have been rushed the first 2 times) the I was able to put it in gear. There are fewer than 500 miles on this new vehicle. It hasn't hapened again, but this seems very dangerous. I have an appointment to take it to the dealer.
As I was driving on the interstate in miami florida my steering wheel turned to the right but my vehicle kept going straight and I heard a loud clunk from the front left of the vehicle. I was able guide the vehicle off of the interstate with great difficulty and took it to the closest dealership. There I was able to take a picture of what looks like a failed weld on what you could call a track bar or steering bracket. *tt
After turning the steering wheel straight after a left turn, just before it hits the 12 o'clock position, the power steering locks up or resists. Does not happen all the time, mostly when the engine is at full operating temperature. Sometimes the resistance is strong where it can cause you to fight it and over correct. I can here a clunking sound through the steering wheel that originates at power steering motor. This clunking does not happen when the engine is cold, only when the engine is hot and when I'm experiencing this problem. *tt updated 9/20/18
