Selected complaints filed with NHTSA by 2018 Jeep Wrangler owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2018 Jeep Wrangler. The contact stated while driving approximately 65 MPH and lowering the sun visor due to the sun glaring into his face, the contact stated that the sun visor detached from a retaining pin on the sun visor arm and hit the contact in the face. The contact stated that he was so startled from the strike of the sun visor that he swerved to the left and almost into oncoming traffic. The contact stated that he was able to place the sun visor into the closed position, but that whenever the sun visor was unhooked, it was hanging straight down and was blocking a portion of the windshield, reducing his visibility while driving. Additionally, the contact stated that the side view mirror toggle switch was no longer functioning, and the contact was not able to adjust the position of the driver's and passenger's side view mirrors. …
My vehicle defrost was on for the back defroster on my way to work as it was one of the coldest days where I live. I work for the fire department and work 48 hrs on. The second day of my shift one of my coworkers noticed the back window broken out on my jeep. Upon looking at what caused it there is burn marks where the rear defrosters touch the window. I initially called the police but they agreed the window was broken due to the rear defroster wires burning the window causing it to break out. Jeep sent out an engineer and is denying all liability. There are TONS of people reporting this on the jeep forums/blogs. I have pictures to prove the burn marks. It appears it happens so often that a jeep sales company "Quadratec" is sold out of replacement rear windows. One guy posted on the Jeep Forum it happened while he was driving 70 on an interstate. …
The contact owns a 2018 Jeep Wrangler JK. The contact stated that while driving at an undisclosed speed, the front windshield wipers failed to operate. An independent mechanic was contacted and reached out to the dealer to obtain a wiper power module for the repair; however, the part was unavailable. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 11,000.
My back window on my Jeep Wrangler will not zip back up all the way. I have only unzipped the back window once, and that was to wipe the inside of the window because it was hard to see clearly though the back window. When I tried zipping the window back up, the zipper did not zip up all the way, and now there is an opening, and water is getting into my jeep. The zipper has never been used except this time, so I could clean the inside of the window. This incident happened about a month ago, and now so much water has come through the opening, it has rusted and ruined my brand new Jack and Jack lift that came with my jeep. …
The driver's side sun visor falls down blocking your view while driving. It pops out of the socket meant to secure it. In researching how to fix it, I located many threads and concerns, including homemade fixes (due to costs) but many things fail causing it to fall down. One person said they were hit in the head with it. From online comments, most fail after the 3 year warranty. As mine did. Estimates online show it costs around $400 to fix. There is already limited vision in Jeep windshields, this is a major concern as the only way to fix is to hit it hard back into the socket.... while driving. I've used a hand gel container to even my hard cell case to secure it. Thank you for considering. I believe this has been an on-going issue with Jeeps with older recalls.

While my vehicle is being repaired for steering issues I was given a loaner vehicle which is a 2020 JLU Sport. Driving the vehicle went to put down the driver-side visor to block the sun. When I did that the visor fell out of the arm. I had to act quickly to move the visor from obstructing my vision of the roadway. THIS IS EXTREMELY DANGEROUS! The few seconds it took to move the visor so I could see the road could have resulted in an accident had there been more traffic on the roadway. This is not considered a powertrain issue so therefore it is not covered by Jeep. My vehicle has the same issue. After some research, there are a lot of other vehicles affected by this. Faulty equipment manufactured by Jeep. THERE NEEDS TO BE A RECALL PROCESSED ON THIS ISSUE.
I have had the rear defroster tab re soldered at dealer under warranty. I don't use the rear defroster because it is parked in garage. After a cold spell at the end of January 2024 heading out on road trip I turned on the rear defroster, 5 minutes down the road the rear window exploded sending glass everywhere. When inspecting the broken window I noticed a burn mark on a sticker where the tab is connected to the glass. This could have caused an accident if traveling on the highway. Jeep has been repairing window tabs when they should be replacing the entire window.
My soft top has never been unzipped, and the back plastic windshield has started to come apart. This causes water to get into my car when it rains. So much water got into my car from the exposed opening in the back window, my car jack actually rusted and cannot be used, so now I have no jack for my car. This opening also causes bugs to get in and lay eyes or make nests, putting me at potential risk to get stung. The water has also caused a build up of dirt on the back windshield, causing extreme difficulty to see out of the back windshield.
Sun visor and post fall out of ceiling into line of vision any time you touch the visor. Has happened multiple times just going over a bump. There are 100s of reports of this issues on various jeep sites. The clip that holds the visor in is defective and has happened on both driver and passenger side on my vehicle. This happens on all trim levels and both 2 and 4 door models of the Wrangler for any of the JL series of Wrangler. It has not been corrected to date.
Driver's side sun visor mount failed while driving. Had visor unclipped to block sun in driver's door window while driving on freeway. Mount broke and the visor unexpectedly hit me on the left side of my head, startling me and and almost caused an accident. The wires from the HomeLink switch group was the only thing that stopped it from falling off. From reading online this is a pretty common problem. There are aftermarket parts to fix the problem.
