2026 Nissan Frontier problems

“While driving my 2026 Nissan Frontier PRO-4X at highway speeds, the vehicle intermittently loses the ability to accelerate. The engine remains running, but pressing the accelerator produces no increase in vehicle speed or engine RPM. No warning lights or diagnostic messages appear when the condition occurs. This creates a significant safety risk because the vehicle cannot maintain or increase speed in traffic. The vehicle has been taken to an authorized Nissan dealer on three separate occasions. The dealer was able to reproduce the condition but has not identified a cause or implemented a repair. The defect remains unresolved and continues to present a safety concern.”

“I bought a brand new 2026 Nissan Pro4x from a dealer in Murfreesboro, TN. The hood was misaligned (fitment), which the service department agreed need to be corrected, and there was a significant scuff below the clear coat on the hood. Nissan has refused and denied the claim, even though it is well documented. I went to other Nissan Service Departments and they refused to do the paperwork. I do not believe that Nissan North America warrants the brand new body work on their brand new vehicles. They are not honoring their warranty.”

“The contact owns a 2026 Nissan Frontier. The contact stated that the vehicle was towed to a dealer due to ongoing electrical issues. Prior to towing the vehicle, the radio failed to turn off, and the engine failed to shut off while attempting to turn off the vehicle. Upon inspection, the dealer diagnosed the vehicle with battery failure. The dealer attempted to disable the radio, rearview camera, side-mirror warning signals, and advanced safety systems to prevent the battery drain; however, the software did not provide the option to turn off the features selectively. The dealer turned off the display screen as the fix. The contact had experienced an electrical failure with another similar vehicle. The manufacturer replaced the first Nissan Frontier vehicle with the current vehicle, and the central display and safety features were now disabled by the dealer as a temporary repair. The vehicle was towed to the dealer. The manufacturer was notified of the failure. The failure mileage was 2,700.”

“The contact owns a 2026 Nissan Frontier. The contact stated that while driving at various speeds on several occasions with the cruise control engaged, the cruise control disengaged independently, and the vehicle decelerated quickly. The contact stated that the failure mostly occurred while driving uphill. The vehicle was taken to a dealer to be diagnosed; however, the failure was not duplicated. The manufacturer was notified of the failure. The failure mileage was approximately 4,700.”

“I went into the Nissan dealer with my Nissan Pro4x with 900 miles on with a lowspeed "thunking" sound coming from the rear end. On the highway the truck vibrates really bad at about 60-65 mph. The dealer (NUCAR Nissan of Allentown, Pa (484)223-0564, service writer Simone) inspected the vehicle and "road force balanced" the rear tires. Both rear tires were found to be bad.....900 miles on the vehicle! The dealer (Simone) claims they do not warranty tires, "Call Hankook", they told me. I called Hankook they provided me a reference number #[XXX] and told me they only deal with the dealer service department. I went back to NUCAR Nissan of Allentown, Pa. They (Simone) again told me they can't help me with warranty tires?!! This is an unsafe condition. I have not been driving the vehicle, except for short trips around town, because I'm afraid this condition will result in a tire failure just like the Firestone tire failures of the late 90's early 2000's. I have a copy of the dealers service report if you need it.”

“While driving North on I79 in dayligh I attempted to engage adaptive cruse control. The indicator lights on the dashboard were too dim to be visible and I was unable to tell if cruise control was on or determine what the speed setting was. After successfully engaging the control using buttons on the steering wheel the truck began accellerating strongly. I was unable to tell what the speed setting was but it must have been in excess of 80 mph as I had to turn the control off at that point. I returned truck to dealer and was told that lack of brightness for this indicator (and several others, such as turn signal indicators) was a design issue and could not be repaired by the dealer. I have tried every remidy I could find, even had the dealer's sales person take pictures of the dash while driving to verify the issue.”
