In owners’ own words

Welds on track bar mount not lined up correctly. Throughout the rest of the frame, lots of slag, misaligned welds, bad penetration, malformed weld caps, spatter, and porosity
I looked under my brand new Wrangler jl after hearing people complain about bad welds. Sure enough, my welds are awful. A Jeep service technician told me there is no way this should have been able to leave the factory. As of right now, Jeep has not done anything for me. Feel very unsafe in this vehicle. I hope Jeep has a recall soon.
Many welds on the frame to include the track bar are extremely porous. If/when the track bar weld gives the vehicle will result in a total loss of steering. Making it a high risk for accident and injury
Steering wheel bracket now welded on to frame properly. It has fallen off car causing steering to be floating and dangerous
Frame welds does not pass your safety standards and Jeep admitted that it was bad and they was going to switch jeeps but all the new jls are bad and starting to rust they have porosity real bad all over
