| Power Train 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.
Drive shaft/ drive line noise concern with being disabled. Dealer confirmed noise states "repair under review".
Purchased new 12. 12. 25, drove 3 miles and heard clunk in transmission, went into limp mode at mile 23. Flatbed back to dealer, they replaced solenoid valve and said was good to drive. Drove away and still have loud clunk in transmission on downshifting. 1. 5. 26 dealer still has vehicle, no resolution.
