2023 Nissan Frontier

Muffler developed hole in the top of it prematurely and melted the main wiring harness due to a known design flaw. The vehicle is still at the dealer awaiting repair. All warning lights came on, 4 wheel drive was disabled, center console lost power and hvac was disabled. Safety was put at risk as this happened on the nys thruway and the vehicles main wiring harness was actively melting/shorting while driving. The shorts disabled all Safety features like lane assist, detections, and abs. Transmission would also not down shift properly leaving me unable to safely accelerate. Im unsure if the tail lights were still operational or not but wouldnt be surprised if they weren't as many other systems to the rear of the vehicle were fully disabled. The truck is at the dealer I have a quote and video of the muffler and melted wiring harness. The truck is not safe to drive but the problem is constant. This is a known problem by nissan as theres a tsb to place a larger heat shield over the wiring harness.

I purchased a pre-owned certified vehicle in June of 2025 it was a 2023 model with approximately 23k miles on it. In August of 2026 I was driving on the interstate and the vehicles warning lights came on and the vehicle shut down completely at a speed of 70 mph. The safety flashers quit working along with the headlights leaving the vehicle totally dark on a remote section of Interstate at night. I had the vehicle towed to a Nissan dealership and I was sent a video of what happened from the certified Nissan technician. I can provide the link to the video upon request. The technician stated in the video that the muffler had developed a very large hole in it and the heat from the exhaust coming from the hole melted the vehicles wiring harness. I feel this is a very dangerous situation as it could cause a vehicle to catch fire. It also caused the emergency lights to not work and all of the other vehicle systems stopped working. I did some research online and found that this is a well documented issue with this make and model of vehicle. The manufacturer has even went as far as offering an additional heat shield for purchase which I only recently found out about. 1. I have the old exhaust system available for inspection. 2.The vehicle could of caught fire of we could of been hit by another vehicle since it was night time and the lights quit working. 3.I am unsure but there are many well documented cases available from a simple online search. 4. Just the service center. 5.It was sudden and there were no warnings and the vehicle had passed a certified inspection 11 months prior with nothing noted.

The power door lock system intermittently malfunctions. During the initial failure, the passenger rear door lock seized in the unlocked position and could not be manually operated. The vehicle was taken to an authorized Nissan dealership, where all three passenger door lock actuators were replaced. Following the repair, the seized lock condition was resolved; however, the underlying malfunction continues. The passenger front and passenger rear doors will unlock electronically but will not lock using the key fob, interior lock switch, or intelligent key functions. The driver rear side door does not respond to electronic lock or unlock commands. The only way to secure or access the affected doors is by manually operating each individual door lock. The malfunction affects three of the four doors simultaneously and occurs intermittently without warning. No warning lights or messages are displayed when the failure occurs. This defect creates a safety concern because the vehicle cannot be secured as designed, and passengers may not be able to quickly access or enter through an affected door without manual intervention. In an emergency, delays caused by manually locking or unlocking doors could impede access to passengers or evacuation from the vehicle. The issue has been reproduced multiple times and confirmed by an authorized Nissan dealership. Although the passenger door lock actuators were replaced, the malfunction persists, indicating the repair did not correct the underlying defect. The vehicle remains available for inspection.

While underway at speeds under 20 mph. Vehicle hesitates and lurches creating a danger when taking off from a stop light. Vehicle may delay acceleration from a stop, which can feel unsafe in traffic and in merging situations.This activity is uncontrollable as the driver has no control and could lead to an accident or injury to pedestrians or other wise. Another problem is rough shifting, hard downshifts and a jerking. There is both an audible clunk and felt responce or "shift shock". Potential safety risk of hesitation or unexpected gear changes may compromise vehicle control. I have reported and visited the Bradenton Nissan dealership. (2 times) to no avail.

Bought my 2023 Nissan Frontier PRO 4X last year and immediately noticed a clicking sound coming from the steering wheel. This noise only occurs while driving and making slight adjustments to the wheel. The noise ranges in loudness and intensity and at times can be felt while holding the steering wheel. Reported issue at 2 separate dealerships so far with no resolution offered. Concerned that the constant clicking/rubbing in the steering column may lead to a catastrophic failure while driving.
