2023 Nissan Frontier transmission problems

Filed Sep 11, 2026 · Acceleration, Electrical · NY

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.

Transmission shifting harshly and may have to be replaced

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.

•What component or system failed or malfunctioned, and is it available for inspection upon request? [Presumably an issue with electrical (alternator failure on 8/15/2024, then again on 9/3/2024, dead battery)] •How was your safety or the safety of others put at risk? [On both dates described above, the vehicle lost complete power and was unable to be restarted. The loss of power occurred in very busy lanes of traffic, causing me (driver and sole occupant) to exit the vehicle and push it our of active lane of traffic. In both cases, the stall caused other motorist to brake hard to avoid hitting my stalled vehicle and/or to pass me on right hand shoulder.] •Has the problem been reproduced or confirmed by a dealer or independent service center? [In both situations, the vehicle was towed to the dealer where vehicle was purchased, and service to the vehicle was provided. On first occasion, I was told the vehicle had a bad alternator, and that the alternator was replaced. On the second incident, I was told the battery was dead, and the battery was replaced.] •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? [Per service tech, a Nissan engineer visited the location and observed the vehicle.] •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? [In both cases, at no time did any warning lights appear prior to loss of power. There were no other indications a power failure that would lead to the vehicle suddenly stalling in busy lanes of traffic was imminent.]

On July 15 2024 my 2023 Nissan Frontier died while running. I had stopped briefly and the entire engine completely died. I attempted to re-stared the truck multiple times. Once the tow truck driver got there he jump started my vehicle which resulted in it finally turning on. I advised my service advisor of this and the vehicle was towed to the dealer. My service advisor had the battery tested and stated everything was normal but they did see a code for “low voltage”. The service advisor said there was nothing he could do for me since the battery appeared fine and they could not replicate the issue. Thank god I was not in a dangerous area and could push my vehicle. I am afraid this problem will happen again since they did nothing to fix the issue and could not diagnose the problem I feel unsafe driving this vehicle.

When setting remote control and the vehicle needs to speed up there are times when the vehicle will lunge forward. When in lower gears there are times when the vehicle is like trying to find a gear. No accident at this time. I have asked if there have been any recalls on this through the company and they said no.
