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.

The contact owns a 2023 Nissan Frontier. The contact stated that when applying the accelerator pedal, the vehicle suddenly accelerated and lurched forward. There were no warning lights illuminated. While leaving a store and entering traffic, the vehicle accelerated and crashed into an unknown vehicle, which spun and crashed into another unknown vehicle. The driver was able to drive the vehicle away from the scene. The driver sustained a concussion but did not seek medical attention. The air bags did not deploy. A police report was filed. There was no reported fire. The local dealer was contacted before the crash. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 4,500.

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.

Yes it-??s available for inspection. Sudden increase in speed under certain condition could be a safety issue. This problem has been identified by another owner and taken to Nissan (Apple) York, PA. The problem happened after leaving the Nissan lot on the way home, less than 200 miles. During use of intelligence cruse control, set at 70 mph, came up on a vehicle doing 60 mph and the system slowed my vehicle down to 60 mph, when I was able to move into the passing lane my vehicle down shifted hard going to 6,000 rpm-??s, my truck surged in mph until it caught up with the set speed. The amount of down shift is excessively too much, this happens on small hills and the rpm-??s go to around 4,500 rpm-??s.
