SLUDGE IN ENGINE- UNDER 100,000 MILES We had been keeping up with all recommended services, and it is cosmetically perfect, but the car is now a total loss. A Check Engine light came on, and we began to notice a tremor/shake and took it to Southern Team Nissan. The Nissan dealer diagnosed sludge in the engine and said it would need a total engine replacement. The Nissan dealer advised that the cost of that would be more than the car was worth. After they pulled the pan to check if there was definitely sludge, the car then shook so badly that it felt unsafe to drive. Research shows that this is a known issue, with many cases of documented VQ35DD sludge problems. We see many listed cases on this website under complaints for 2017 Nissan Pathfinders.

ENGINE

Component/system failure. Engine shut off while driving @ 70 mph. The car first shifted into neutral all on its own, system shows AT MALFUNCTION. Vehicle was towed to nearest dealership so it is available for inspection. Safety concern is that the vehicle died in 2nd left hand side of road my had my husband not been able to essentially coast and cross 2 lanes of traffic to get to shoulder the vehicle could have potential been sitting in the 2nd left hand lane where traffic was going 70 plus mph. The dealership has not been able to reproduce issue other than seeing the AT Malfunction code, the vehicle is not starting as it did on side of highway. No other inspections have been done to my knowledge. No messages or warnings appeared prior to the vehicle switching into neutral and turn off engine.

The vehicle veers towards the right, even though a wheel alignment was completed on 7/1/26. On 7/28/26 when driving the vehicle, it wouldn’t accelerate properly, it felt sluggish and although the gas pedal was depressed it was struggling to pick up speed. As the vehicle was attempting to shift between 2nd and 3rd gears the car jolted forward and the traction control and collision lights came on. Both lights reset when the car is off but the vehicle jolts and beeps w/in 5 mins of driving and then the lights come back. This has been happening everyday multiple times a day since 7/28/26. On 7/30/26, the Check Engine light came on and has stayed illuminated w/ code P0101 populating on the obdii reader. The vehicle is currently at the dealership, I am awaiting a diagnosis of the issue which they said may take 3-4 days. I have only had this vehicle for 46 days.

ENGINE

The car stalled three times and died in active traffic. The breakdown was so hazardous that the police department had to intervene and push the car out of the road and had to tow the car more than 3 times and was at the Nissan Dealership for over one week. I paid Nissan dealership $5,000 to repair this specific, life-threatening defect, but the car returned to me unfixed.The vehicle is unsafe and has been sitting parked at my house for 3 months because I cannot safely drive it. It keeps stalling, dying in traffic and making a loud grind noise. I need help.

ENGINE

After only 110,000 miles, my local Nissan service center (Advantage Nissan, 5101 Auto Center Blvd, Bremerton, WA 98312) states that the timing chain is loose. The repair estimate is in excess of $6000. The expense is because it requires removal of the engine to effect repairs. Research reveals that timing chain issues at 100000+ miles are common for this vehicle. It is the expectation that the timing chain system last the lifespan of the vehicle. The result is that owners pay more than half of the original price simply for maintenance because of Nissan's choice to use substandard parts in a critical system, a fact they learned with earlier models where timing chain issues and recalls occured. I'm retired and can't afford to maintain this vehicle by spending $6000 every 100000 miles.

2014 Nissan Parhfinder FWD Premium: this vehicles CVT joint failed that shirt the engine down to about 10 miles an hour immediately. Which caused me the driver to find a place to pull it off the road quickly. If a person or myself could not have a point to pull off the road or someone was behind then could have been rear ended the vehicle and major damage to the vehicle or person driving. Which there was and they were about to go around the pathfinder. The vehicle also may have blown the transmission. Unknown damage right now. But the pathfinder stalled out two times while driving it before it shut totally down on the hwy. I had contacted Nissan and we never got together on a date and time for a phone call with an Arbitration specialist. I had called them back several times and never could connect with them.

While driving the vehicle at approximately 25 miles per hour, on its own, the vehicle put itself into neutral and a warning light to exit the vehicle appeared. Thankfully we safely pulled the car over to the side of the road. Upon restarting the vehicle, it operated normally. Had this incident occurred at a higher rate of speed or on a busy road, there could have been very different consequences.

ENGINE AND ENGINE COOLING

The contact owns a 2024 Nissan Pathfinder. While the vehicle was parked, the contact became aware that coolant was on the garage floor. The vehicle was taken to a dealer where it was diagnosed with a coolant line leak with coolant going back to the third-row seat, and the leak was near the passenger’s side rear tire. The contact was informed that the coolant lines needed to be replaced. The vehicle was repaired, but the failure reoccurred 15 months later. The contact stated that during the failure, the vehicle was being driven at an undisclosed speed, and the A/C unit failed to operate as intended. The vehicle was taken to the same dealer where it was diagnosed, and determined that the coolant lines were leaking and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 8,000.

I purchased the car July 2024 by November 2024 the transmission failed and had to be replaced. Replaced, not repaired. By October 2025 it failed again. The car sputtered and then would not drive. This time the dealer said other repairs had to be done first before they would officially say the transmission failed. Then I found that Nissan had a manufacturer's defect with the transmission. So they should have it replaced it in 2024 for free. Since I refused to make any more repairs on the car they would not replace the transmission and so the car became dangerous to drive. I have reached out to Nissan Corporate several times. I have filed complaints with my county and state Consumer Protection Agencies. I have contacted my senators as well. I am a senior citizen and I need a car. I would like for Nissan to reimburse for the expenses for the transmission replacement and what I owe on the car. Or they can provide me with another car. Thank you.

Rear Door / lift gate will not go all the way up or stay up without manual assistance, causing 2 head injuries and 2 arm injuries on recent occasions. We have confirmed with the dealer & one Nissan Certified Mechanic that this is a common problem. The dealer & 2 mechanics have said they do not know how to fix this without replacing the entire lifting assembly. We did not ask for estimates. We should not have to, but we can live with the problem now that we are aware of it. Transmission was replaced with new Nisson equipment by the previous owner, costing $5,000+. The problems we are having are the same they were having. The vehicle runs rough, hesitates, vibrates & shakes a lot. It is not very safe in traffic. There is a place for a dipstick to check transmission fluid. We have confirmed with 3 parts stores, 2 mechanics & finally with Nissan, they did not make a dipstick for this car or several other models. One way to check the transmission fluid is to jack up the car, remove a port on the transmission & fill it until if overflows (Cost is approximately $1,100.00, vs a dipstick costing less than $30.00 retail for comparable cars) Another way to check is to jack up the car, drain the transmission fluid, change the filter, replace the seal & cover, then pour in the exact correct amount of transmission fluid through the dipstick hole. However, the only way to know it is actually full is to leave the above-mentioned port out until the fluid overflows. (Our 3 cost estimates range from $1,400.00 to $1,850.00) Had we known of the transmission problems occurring with many if not most Nissan cars, we would not have bought the vehicle. Our research shows these are very common problems with this car & Nissan. We don't know if this applies to what you do, but this car also burns through spark plugs & ignition coils very quickly. We have had to replace all spark plugs 2 times plus 8 ignition coils in the 2-1/2 years we have owned it & driven it only 28,000 miles.

We have been documenting a oil leak on the timing chain cam shaft cover. When the motor heats up the engine seeps/leaks oil on the top of the side of engine. This has been documented for the past few months starting at 37,099 miles when we noticed it, date of first notice was on 4/29/2026. We have pic with time stamps and have taken it to dealership to inspect and have written many times of the issue. We have also filed a consumer affairs and BBB autoline complaints. This is an issue safety issue bc oil can start a car fire, it can also cause a motor to malfunction. This is a safety concern. The dealer says their is no leak at all but they wipe off oil and it returns that an issue. We bought this pathfinder in Oct of 2025 and put on now around 42k miles and it is still an active issue.

ENGINE

The vehicle has developed a persistent and progressively worsening rattling noise from the engine during cold starts, along with intermittent rough operation. The symptoms are consistent with a malfunction or defect in the engine timing chain system, including possible timing chain stretch, timing chain tensioner failure, or related internal engine components. This condition presents a serious safety concern because the timing chain controls engine valve timing. A failure or severe degradation of this system could result in sudden engine stalling or complete engine failure while driving, increasing the risk of a crash without warning, particularly in traffic or at highway speeds. The issue began as an intermittent startup rattle and has steadily progressed in frequency and severity. No consistent warning lights were present in the early stages, which may delay driver awareness of an impending failure condition. The vehicle has been inspected by a dealership service department, and the concern was acknowledged, but no repair or corrective action has been performed. The condition remains unresolved and continues to progress. Based on owner reports and service feedback for similar vehicles equipped with this engine, this issue appears to reflect a potential widespread defect pattern affecting the timing chain and/or tensioner system in this engine family, rather than an isolated incident. Multiple reports describe similar symptoms occurring around similar mileage ranges, suggesting a possible systemic reliability defect. The vehicle is currently still operable but is operating with a known and worsening engine defect that could result in catastrophic engine failure without warning.

Hi ! I just purchased the 2024 Nissan pathfinder SL on March 13th , 2026 . Three days later I noticed a slight vibration to the car . I was told it was the mount they’d replace both mounts . Get the car from getting the mounts replaced , & when I went to leave with the “ repaired “ the car sounded horrible while in Reverse. It was a loud sound more than just a vibration. I immediately went into the dealer and they said they’d replace the other two mounts . Fast forward to that appointment, I get a call it needs a new motor . I’m not sure the mileage on the vehicle but it’s less than 46k . The mechanic shop in Macon , Ga has had the car two weeks. They replaced the mount close to the transmission with a OM mount , said the previous one was a defective mount . Now they have no clue what is wrong with the car . This car is so “ new “ to be having these issues. So now I’m waiting to hear what the next steps are on this car . Such a beautiful vehicle truly ! I just don’t know if this mount / transmission is going cause me issues nonstop within the car .

My 2024 Nissan Frontier has experienced repeated complete power loss more than three times. The vehicle shuts off unexpectedly while on the street and cannot be restarted. During some incidents, even the emergency hazard lights did not work. I had to use jump cables to restart the vehicle. I first reported this issue to Nissan in January 2025. The dealer kept the truck for about one week but stated they could not find anything wrong. The problem continues, including incidents on 04/20/2026 and 04/23/2026. This creates a serious safety hazard because the vehicle can lose power in traffic and increase the risk of a crash or injury.

The contact owns a 2024 Nissan Pathfinder. The contact stated that on several occasions when the vehicle was started, the RPM was excessively high, and the engine was revving excessively. The contact stated that while driving on several occasions at various speeds in rainy weather, the Forward Collision Avoidance notification activated inadvertently via the side mirrors on several occasions. The vehicle was taken to the dealer; however, the failure could not be duplicated. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 35,000.

ENGINE

While driving, the vehicle experienced sudden and complete loss of throttle response, resulting in little to no acceleration. This occurred in active traffic and created a dangerous situation where the vehicle could not maintain speed or safely move out of traffic. The vehicle has been serviced multiple times by Nissan of Kenosha, including a full transmission replacement under warranty. Despite these repairs, the same throttle failure has occurred repeatedly, including within hours of being returned as “repaired.” Most recently, the throttle failed again while driving on a public street, and I was only able to move the vehicle into a driveway with minimal acceleration. The vehicle is currently not drivable and remains unsafe to operate. The dealership has not resolved the issue and has released the vehicle multiple times in an unsafe condition. This is an ongoing safety defect involving loss of acceleration and vehicle control.

I was driving the vehicle and it just stopped on the highway, no warning no kickback no precursor that something was wrong with the vehicle, and it stopped, the warning sign: Not available System malfunction came on and then the entire electrical system shut down. I had to have the car towed home because it would not start. I went to the dealer on several attempts and no help was rendered. I was told to either come back or there are too many cars, just really getting the run around for a matter that is fatal. I was driving with my family in the car and it just stopped. I almost had an accident, it could have been fatal. This is unacceptable.

⸻ My 2022 Nissan Pathfinder experienced a catastrophic engine failure at approximately 70,000 miles. The vehicle suddenly developed severe engine knocking and required a complete engine replacement. There were no engine warning lights or oil pressure warning lights prior to the failure. The vehicle had been maintained according to the manufacturer’s recommended service intervals, including oil changes using full synthetic oil. The Nissan maintenance system indicates oil changes at approximately 10,000 mile intervals. Because there were no warning indicators prior to the failure, the issue occurred without any notice to the driver. A sudden engine failure without warning could present a potential safety risk if it occurred while driving in traffic or at highway speeds. The repair required a full engine replacement at a cost exceeding $8,000. The vehicle was just slightly outside the manufacturer’s powertrain warranty at the time of failure. Given the relatively low mileage and lack of warning indicators before the engine failure, I am submitting this complaint so the issue can be documented and evaluated for potential safety concerns or patterns of engine failure in this vehicle model.
