2018 Nissan Pathfinder: check engine light

Filed Aug 7, 2026 · Engine, Transmission · AZ

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.

The contact owns a 2018 Nissan Pathfinder. The contact stated that while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal. The failure persisted, and there was an abnormal knocking sound coming from the engine with the check engine warning light illuminated. In addition, the vehicle hesitated while starting the vehicle and pressing the Push to Start button. The vehicle was taken to a dealer, where a diagnostic test was performed, and the contact was informed that there was sludge in the engine oil. The mechanic stated that sludge was found in the oil due to a lack of regular oil changes. The contact disputed the claim and provided receipts that all oil changes were up to date. The contact had the engine taken apart by the dealer and an independent mechanic, and both discovered metal shavings inside the engine, which had resulted in the engine failure. The manufacturer was notified of the failure but offered no assistance. The vehicle was repaired by the independent mechanic. The failure mileage was approximately 93,000.

The disabled vehicle when delivered by flatbed car hauler unit to the nearest dealership, Petro Nissan, 47 miles from the breakdown site would not move at highway speed but only jerked/bucked and crept along at little more than a fast walk. This condition was last experienced when the vehicle had been on a remote undulating interstate for about 2 hours. The check engine light had reappeared after being recently reset and the engine revving and loss of ground speed started causally then increased in frequency and intensity until totally failing to the point of forcing me to creep with emergency flashers in mode on the shoulder to reach an exit two miles ahead. The high RPM revving coupled with the ground speed loss condition initial stages occurred each of the two prior days. Two Nissan NA dealerships in those two days had performed diagnostics and service. On each prior day the check engine light, the high revving engine RPM, and the ground speed loss occurred. On each day a potentially serious safety issue arose. Initially an attempt to match speed and merge with traffic at an onramp and again when (using cruise control) during which the vehicle system attempted an automatic acceleration to maintain speed on rolling hills. Both conditions forced me to the shoulder to avoid a potential accident from immediate and drastic ground speed loss and engine revving at or above 4500 RPM After each of these incidents a Nissan NA dealership was consulted and services were performed. In each case I postulated to the service advisors that the transmission sounded/felt like it was slipping on acceleration when the vehicle/ transmission had heated up from extended driving. Both days service advisors checked for diagnostic codes of transmission issues but never mentioned emission issues aside from mass air flow sensor or ABS sensors apparently either not seeing or not looking beyond transmission related codes. The first dealer, Illini Nissan, ran diagnostics on 1/6/25,

I purchased my 2018 pathfinder in march 2018 and before I drove it off the lot the mil light came on. They took it to the service dept, said they fixed it. I drove it home and on the way home you could feel the car stutter and when outside of the car you could hear the engine misfire. The aeb light, slip indicator light and mil came on. Took it back to the dealership. They never could figure out how to fix it. They ended up finding another car like mine and I traded vehicles. Now over a year later the aeb light and slip indicator light have come on a couple times. Was told that there was a sensor that was recalled. They fixed that. Now the aeb light and slip indicator lights came on again. Called to get a service appt - days later the mil light came on. It is currently in the service department at the dealership. I do not feel like this problem should be happening already. The car is less than 2 years old. Having the same lights and problems with 2 cars that are identical is scary. There is a problem - it was not a fluke. Everytime the indicator lights come on I am driving on a highway. You can feel the car stutter and you know the lights are going to come on. Then the car jerks a little and the lights come on. Afterwards you can feel the car struggle at times - like it isn't getting enough gas. Although now that the check engine light is on the car is misfiring - you can hear it when it is idling in the driveway.

My husband roger and I purchased a 2018 nissan pathfinder less than a week ago at granite nissan in rapid city, sd. We drove to dickinson, nd to drop off my stepson to see his mother as required by court order every month. The trip there has no cellular service and temperatures that reach subzero. Upon arriving in dickinson, we had the check engine light come on while driving approximately 65 MPH and the rpms became erratic. We also noticed decreased fuel efficiency. The light came on with less than 400 total miles on the vehicle. We consulted the user manual which advised to drive the car to the dealership with the check engine light remaining on. Unfortunately, when we received the notification of ready for pick up, there was no resolve. The serviceman claimed that it was an issue 'currently being investigated by nissan'. He said they cleared the error and that we will notice less efficiency with gas mileage and stated the vehicle wouldn't breakdown but was unsure of what may happen. We purchased this brand new vehicle to better ensure a safe means to drive in desolate areas and in extreme weather conditions while monthly tranporting our son for visitation. The service technician was dismissive/belittled our concerns when asking about safety, especially with the special circumstances and that we have a one year old and six year old who ride daily in the car in addition to our 14 year old who takes the monthly trips to nd. We are waiting for nissan to reply with when and how the error code p34a9, intake timing control will be fixed and if damage to the engine or other parts of the vehicle while this error occurs. If we are stranded in desolate nd in extreme temperatures, our lives will be at risk as even if the 'sos' feature were to be pressed, the nearest emergency responders are hours away. We've inquired with nissan about the safety of this 2018 pathfinder.
