2021 Jeep Wrangler: windshield wiper failure

Filed Aug 18, 2026 · Electrical · VA

After dealer recall 21D inspection on 7/30/2026 I have experienced 2 electrical failures in the recall system, and/or systems associated with recall. The first incident on 7/31/2026 at approximately 9:00 PM my wife, 2 kids, and a neighbors kid were at a stop light for a 4 lane road when the Jeep unexpectedly made a popping sound and shut down. When I arrived I pushed the vehicle into a parking lot and attempted to restart. I was able to restart the vehicle but instantly started seeing multiple warnings including Service Power Steering (code associated with the recall), Throttle body warning, and Warning that the vehicle would shutdown for safety. After the vehicle shutdown the electrical system went crazy (gauge cluster lights flashing, windshield wipers turned off and on, relays clicking). I had the vehicle taken to my mechanic on 8/6/2026 where they determined that the AUX battery was bad (previously replaced in 05/2026) AND the main fuse array fuse N3 was blown. The mechanic replaced both components, tested the vehicle, and rechecked for any new error codes. On 8/11/2026 my wife and 2 kids attempted to leave soccer practice and the Jeep would not start. I brought them home and returned to the Jeep. As it was near closing time for most auto parts retailers I decided to start by having the main battery tested. When I opened the hood to remove the battery I noticed that the engine compartment seemed abnormally hot. I removed the battery and had it tested by AutoZone (failed-only 6 CCA). I purchased a new battery and when I installed I still noticed an abnormally high temperature in the engine compartment. After installing the new battery the Jeep started & instantly displayed a power steering warning. I shut the vehicle down and let it rest approximately 30min. When restarted a low voltage warning displayed immediately. I returned the next day to a dead Jeep. I returned the Jeep to the dealership that inspected for 21D. (Aux batt. bad & main fuse array blown AGAIN)

On October 17th. The vehicle exhibited serious electrical issues when I attempted to start it in my school parking lot. Upon pressing the start button, the car would not start, and all electrical items began malfunctioning. The lights inside and outside the vehicle were flashing, the windshield wipers activated on their own, the horn was beeping intermittently, and the car was emitting alarming noises. The situation escalated when the tow truck driver arrived. He was unable to start the vehicle. Instead, the engine produced a loud revving sound, as if it were about to blow up. This experience was not only frustrating but also alarming, considering the potential safety risks. The dealership said they will get to it as soon as they can, but are 7-10 days booked.

Earlier this year vehicle would sometimes do the following, not at start up but when driving; Wipers on by themselves & driver can't shut off, turn signals inop, Both sides blind spot warning continously on alerting driver every time a vehicle on either side is passed or passes vehicle, anywhere from three to five dash warning lights illuminated. Took to dealer in April 2023 & diagnosed a bad can bus connector. Replaced connector (approx $700). Seemed to be the fix until it started again June 2023. This time all the above issues started up again including loss of power steering. I was on I70 at highway speeds in rush hour traffic and it was very dangerous. Returned to dealer yesterday 6/29/23 Immediately following loss of power steering while vehicle was displaying faults & they read codes. They are booked for 2 weeks so I'm scheduled to drop it off 7/10/2023. Dealer has been fine to work with and willing to help. My chief complaint is I have found numerous others that this is happening to (internet Wrangler JL forum) & I feel like car mfg knows about this and is not doing anything about it.

' immediately after purchase of my 2 door 2021 jeep wrangler jl (anniversary) the rear video camera stopped working at start up, and continued to be an ongoing issue, despite software reinstalls. ' two and a half months after purchase and with just 2000 miles on it, while driving in the rain I noticed that approximately 10 seconds after I put on the windshield wipers, the dashboard light would dim significantly, which made it difficult and distracting to see the speed at which I was driving, or the cruise control. Dimming migrated quickly after that to the monitor which became hard to read or see. Uconnect was also not working with images and audio being in discernable. ' not long after that, I noticed that the cruise control was also increasing the MPH on its own while it was being set. Clearly having electrical issues. ' five days later going somewhere between 40-50mph on a highway, the jeep shifted into manual and I could no longer accelerate. Luckily, there was not a lot of traffic and I coasted to the side of the road and pulled into a parking lot where I stopped the car, shut it off, turned it back on. The car was still working, but I was scared by what clearly could have been a life-threatening circumstance. ' at the dealership while the car was being delivered to me in the garage by an employee, it stopped driving in front of many employees and myself. The windshield wipers were going as fast as possible and rain was pouring down, and the car slipped into manual or park, and becoming undrivable. ' the car clearly has serious safety problems with the transmission and my dealership seems unconcerned about the safety of their clients. The jeep continues to be a concern for me, and I do not feel safe driving it. I also believe this is not a new problem for jeeps.

When driving during a medium snow fall: the front windshield defroster is terrible! Even with the front defroster on high heat, and full defrost mode, the defroster only blows hot air onto the center portion of the windshield. The right and left sides of the windshield get no hot defrost air (no air whatsoever) and snow and ice builds up on the right 12' and left 12' of the windshield. This also causes heavy snow/ice buildup on the wiper blades. Terrible and dangerous windshield defroster design. Air comes out of the center defrost vents only. No air comes out of the windshield vents in front of the driver or passenger. Horrible and dangerous design which makes visibility while driving during a snowfall almost impossible.
