2020 Nissan Pathfinder Complaints

ENGINE — Filed 07/17/2026

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.

A few months after purchase, the power cut off on me. Then it happened again the following year. Then the screen for backing up started going on and off. Then I started feeling like the car was loosing power. In the last 2 years the power cutting off has occurred 3 more times and the rear screen camera has started glitching more where it goes out when switching in reverse.

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.

BACK OVER PREVENTION — Filed 04/15/2026

The back-up camera and display settings image is no longer visible and the dashboard indicates that it is off. The camera is black and does not display anything nor does it provides information that you are backing up. The safety of drivers and others are at risk. As such, the vehicle fails to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."

Airbag needs replacing at 60,000 mile due to TSB# NTB19-07-1D

POWER TRAIN,VEHICLE SPEED CONTROL,ENGINE — Filed 03/01/2026

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 own a 2020 Nissan Pathfinder with approximately 55,000 miles. The vehicle repeatedly failed Indiana emissions testing because the oxygen sensor monitor would not set to “ready,” despite multiple complete drive cycles and no check‑engine light or stored fault codes. A local shop performed diagnostics and found no issues. They reported that another 2020 Pathfinder came in the following week with the exact same problem. My vehicle was ultimately sent to a Nissan dealership, where they determined the upstream oxygen sensor had failed in a way that prevented the ECM from running the emissions monitor, yet did not trigger any diagnostic trouble codes. The repair required full sensor replacement at a cost of $1,450, not covered under warranty. The failure mode is concerning because: • The vehicle gives no warning to the driver. • The ECM blocks emissions readiness indefinitely. • The issue appears to be occurring in multiple 2020 Pathfinders. • Owners cannot legally renew registration without passing emissions. This may indicate a defective oxygen sensor or ECM logic issue affecting 2020 Pathfinders. I am filing this complaint so NHTSA can track the pattern and determine whether a broader defect investigation is warranted. Vehicle Details: • Year/Make/Model: 2020 Nissan Pathfinder • Mileage at failure: ~55,000 • No warning lights, no stored codes • Emissions monitor would not complete • Dealer confirmed sensor failure and replaced part Safety Concern: A failed emissions component that does not trigger a fault code may indicate a defect in the emissions control system or ECM logic. The lack of diagnostic warnings prevents owners from knowing there is a problem until the vehicle fails emissions testing.

SUSPENSION,POWER TRAIN,ENGINE — Filed 04/07/2025

On April 7, 2025, the dealership attempted to sell me a vehicle that was experiencing an engine condition running too lean. I declined that vehicle due to safety concerns. On April 8, 2025, the salesperson contacted me again and stated that a different vehicle had been located that would meet my needs. At that time, I was nine months pregnant and urgently needed a vehicle with third-row seating for my children. The dealership was aware of my condition and urgency. I took delivery of the vehicle that day. Unexpectedly, I went into labor the following day and gave birth shortly after. Because of childbirth and medical recovery, I did not immediately operate the vehicle extensively or discover the safety issues. After being discharged from the hospital, around April 11, 2025, I began using the vehicle and discovered serious mechanical problems that made the vehicle unsafe to operate. The vehicle exhibited engine-related issues and a major suspension defect that affected vehicle stability and safe operation. The vehicle was returned to the dealership, where repairs were performed and parts were ordered, confirming that the defects existed prior to or at the time of delivery. Despite the vehicle being driven a significant distance immediately before sale, the dealership did not perform a basic oil change or standard post-delivery inspection. Operating a vehicle under these conditions raises concerns for engine reliability, overheating, and failure. The suspension defect created risk of loss of control, and the engine condition created risk of drivability issues. These conditions posed a safety risk to the driver and passengers, including a newborn child. The vehicle remains available for inspection if requested.

ELECTRICAL SYSTEM,STRUCTURE — Filed 01/09/2026

Passenger door unlock/lock does not work at all unless done manually by hand and the driver door is beginning to do the same as well. This has begun a year ago. The lift gate button broke off over a year ago as well and is only connected by cables and today (January 9, 2026) while trying to open the trunk the entire silver trim piece flew off towards me. The manual trunk (ours is not automatic) is a poor design and is not made safely to push the trunk button and pull up easily.
