2023 Nissan Frontier

April 2 I was driving to an appt got off on access road and as I pulled up behind another vehicle the acceleration was faster than the pressure on the pedal warranted and the emergency stop-braking warning came on. After it was safe to proceed to my destination I proceeded to a parking spot as I turned to pull in the vehicle rapidly accelerated on its on and jumped the side walk. I attempted to brake but the pedal went to the floor with no braking and the engine was red lining as we crashed. My passenger pushed the engine off button. Front passenger tire was sheered off. No air bag deployment and vehicle likely totalled.

Vehicle Year/Make/Model: 2023 Nissan Frontier Defect Description: The wiring harness connected to the brake stop lamp switch on 2023 Nissan Frontier vehicles contains a design or manufacturing defect that causes premature switch failure. The defect results in the switch overheating and burning out, evidenced by visible charring and sooty residue inside the switch housing. Upon failure, the brake lights may not illuminate when the brake pedal is depressed, removing a critical safety signal for following drivers. Nissan has acknowledged this defect and issued Technical Service Bulletin NTB22-084. However, owners whose vehicles have exceeded the 36,000-mile bumper-to-bumper warranty threshold are required to bear the full cost of repair out of pocket, despite the defect being a known manufacturing issue. Safety Hazard: Failure of the brake stop lamp switch renders the vehicle's rear brake lights inoperative. This creates a significant safety risk to the vehicle's occupants, following drivers, and the general public — particularly under low-visibility conditions such as nighttime driving, inclement weather, or high-traffic situations. In my personal incident, switch failure occurred without prior warning while traveling at approximately 50 mph on a state highway. A warning light did illuminate, but only after the switch had already failed. At that speed and location, safely moving off the roadway was not immediately possible, placing myself and other motorists in a hazardous situation.

The Nissan Frontier (and perhaps other Nissan vehicles employing the same system) equipped with the 'Intelligent Cruise Control' (ICC) exhibits dangerous behavior when a followed vehicle comes to a complete stop with ICC enabled. When this occurs, the Nissan will come to a complete stop, then a warning chime will sound and the vehicle will immediately start moving quickly forward. Since the ICC brings the vehicle to a stop very close to the followed vehicle, if the driver is thinking the ICC will hold the vehicle in a stationary position, it is possible that this behavior could result in the Nissan rear-ending the followed vehicle. This is the result of a flaw in the design of the Nissan Intelligent Cruise Control that releases the brake with little warning when the traffic in front of the vehicle is stopped. A proper design would hold the brake until some manual driver action is taken such as physically pressing the accelerator or the brake. My personal experience was that I was on an Interstate freeway in very slow traffic. This was the first time I had the ICC enabled in slow and go traffic. It was working fine and, when the traffic came to a complete stop, it properly stopped behind the vehicle in front of me. Then, to my shock, my Nissan beeped and started to accelerate forward nearly rear-ending the vehicle in front of me. Luckily, I was able to press the brake in time to avoid a collision, but this is a flawed design and represents an unnecessary danger to the Nissan as well as followed vehicles.

This first appeared on or about 7/2/24. Saw dealership on 7/9/2024. First driving the cruise control failed and showed malfunction. The next morning truck started but numerous things didn’t work like Radio and rear emergency braking. Rear braking was a Malfunction. Also trip A/B were erased.on 7/9/24. Dealer found some previous codes and said might be due to storage switch issue. But the codes seem to point at a distant sensor but stated it could have happened due to low battery volts. Now on may 29th I requested the battery to be load tested because the A/B trip meters had reset twice. Never saw the results of that test. Back in early May I put the battery on the charger due to it showing lower voltage. Battery was at 50 percent at time of charge. Truck sat on lot from Aug 23 till march 27-24 when I purchased it. sorry about going backwards. So dealer stated on July 9th that codes found were old (3556 miles) cleared and drove truck 3 miles with no problems. On 7/11 failed again reported it to dealership. On 7/14 failed again. All failures were with forward collision system. On 7/16 dealer said no codes drove truck no issues so they wouldn’t do anything else , even though it’s a possible safety issue even though I had documented pictures and text messages sent to dealer. They needed it to happen when they drove it. 30 mins later driving home malfunctioned again called dealership immediately on the side of the freeway to report this issue again. Response was a number for a tow truck and it didn’t matter because they weren’t driving the truck. This resets every time the truck is turned off. I explained numerous times that it’s intermittent, that’s the issue and why I have everything documented. So as for now I have a system that malfunctions with cruise control on or not. Truck has 4000 miles on it. Dealer won’t do anything due to it won’t malfunction in their procession. Currently at a loss.

The cruise control on the vehicle is dangerous. When driving through rolling hills the vehicle does not keep a consistent speed. When it loses speed it puts the vehicle in overdrive accelerates to 4500 RPM to speed the vehicle up to the cruise setting. The danger is while on back roads while cresting a hill or rounding a curve the vehicle feels totally out of control. The problem is not limited to back roads, it also occurs while driving the interstate highway. The only way to stop the vehicle during this process is to cancel the cruise control. The acceleration is so violent that it pushing you back in your seat and your head is pushed into the headrest. Ive been on Frontier forums and many people have experienced the same condition. Seems to lie in the newer 9 speed transmission trucks. Seems Nissan does not acknowledge the problem. Needs a Firmware update.

Easily repeatable issue. When at highway speeds adaptive cruise control detects a slower vehicle in my lane. My Frontier slows as expected. When the necessary lane change is made, my engine will suddenly accelerate rapidly until it reaches about 6000 rpms. This also will occur when climbing a moderately steep hill in either cruise mode. This is a safety hazard in that it is extremely distracting, because you have to divert your attention to cancel the out-of-control cruise control manually with the cancel button or brake pedal. I have contacted Nissan Customer Service, as well as had two dealer service calls. They both said that they could not duplicate the issue. According to the in and out milage they didn't drive it. They did say that Nissan is working on this issue.

EL VEIGULO APLICA LOS FRENOS AUTOMATICAMENTE MIENTRAS ES CONDUCIDO NORMALMENTE Y PRENDE DODO EL TABLERO DE LUCES DE EMERJENCIA Y NOTIFICA (FALLA EN EL SISTEMA VER EL MANUAL DEL FABRICANTE Y FALLA EN EL SISTEMA DE FRENADO). SE A LLEVADO EN DOS OCASIONES AL DILER Y EN LOS CUATRO MESES QUE LA TENGO SOLO LAE PODOTO CONDUCIR POR MAS O MENOS UN MES AL MOMENTO DE ESDA QUERELLA SOLO ME NOTIFICAN QUE NO DAN CON EL PROBLEMA SEGUN EL TALLER DEL DILER.

I was driving in the right hand lane on Interstate 95 with my cruise control on. My speed was approximately 65 mph. In the distance I could see a tow truck stopped in the breakdown lane with it's warning lights flashing. I proceeded to move into the next lane to my left. All of a sudden my vehicle began to brake hard by itself and a message that included "25 mph" began flashing on my dash in the middle. I had to make a split-second decision to put my floor on the accelerator pedal and press to maintain a safe speed since cars in front of and behind me were going close to 60 mph or more and I was afraid I could be rear-ended. I shut off the cruise control. The message including the words "25 mph" continued to flash for about a minute or less and then went away. I cannot find any information in the owners manual that would indicate why this all happened but it could have resulted in a rear end collision if I had not reacted as fast as I did. I've never experienced this kind of thing in all my years of driving. I'm 63 years old and I've been driving since I was 16.
