First step would be to get a new mechanic. Where abouts are yiu located? There are a few really good experienced Jeep workshops spread around the country.
First step is check all ball joints, tie rod ends and track bar joints for any movement as mentioned above. I do this by setting up my phone in video mode and recording each joint whilst rotating the steering back and forth half a turn. Search for SeaComms on youtube and there is a pile of videos on there of my front end looking for the source of tje wobbles. Mine was worn ball joints in the end combined with worn tie rod and draglink ends with inly 48000km on them - the factory component's rarely outlast the warranty so if yours have not been replaced they should be. All were replaced under warranty and problem gone.
Also Check wheel alignment, should be 1 to 3mm toe in and around 4° caster. Most likely will be lower caster which whilst will not cause death wobbles will allow them to happen easier.
Also might be worth explaining what you mean by death wobbles as their is a lot of misinterpretation around.
Death wobbles is a violent side to side shaking of the whole front end that usually starts around 80kmh or higher, often triggered by a bump or a bend and will only stop by bringing the vehicle to an almost complete stop.
