2022 Nissan Pathfinder

I am reporting a systemic safety defect regarding the rear Air Conditioning (AC) lines/hoses in the 2022 Nissan Pathfinder. The rear AC lines are prematurely corroding and leaking refrigerant, mirroring a previous recall Nissan issued for the front AC lines due to similar corrosion issues. On June 13, 2026 at approximately 86,000 miles, my vehicle's rear AC system failed due to a rotted, leaking line. This defect creates several critical safety hazards: 1. FLAMMABILITY HAZARD: The 2022 Pathfinder uses R-1234yf refrigerant, which is classified as an ASHRAE A2L mildly flammable gas. A rapid, uncontrolled leak of pressurized R-1234yf near hot exhaust components or electrical wiring creates an unmitigated vehicle fire risk.  2. TOXIC GAS EXPOSURE: If R-1234yf ignites or comes into contact with high heat, it thermally decomposes into hydrogen fluoride. This turns into highly toxic hydrofluoric acid upon contact with moisture, posing an immediate inhalation and chemical burn hazard to vehicle occupants and first responders. 3. OCCUPANT HEALTH RISK: Sudden climate control failure in extreme summer temperatures poses a risk of heat-related illness for vulnerable passengers, like children or the elderly, in the rear seats. 4. REPEATED DEFECT: Nissan previously acknowledged their factory AC lines were prone to premature corrosion but only recalled the front lines. The rear lines suffer from the exact same material or manufacturing defect. This is a widespread issue widely documented by numerous 2022 Pathfinder owners. I request that NHTSA open a safety defect investigation to expand the previous recall remedies before this visibility hazard causes a severe accident.

Components Affected: STRUCTURE:SUNROOF | ELECTRICAL SYSTEM | VISIBILITY/WIPER Description of Safety Hazard: My 2022 Nissan Pathfinder suffers from a severe, chronic manufacturing defect causing substantial water intrusion into the vehicle's cabin through the sunroof assembly during rainfall. To date, the manufacturer’s authorized dealership network has attempted to repair this exact leak three separate times and has failed to cure the defect. This unfixable water leak creates two distinct, critical safety hazards: 1. Electrical Failure/Fire Risk: Water actively flows into the headliner, pooling behind the dashboard and running down the A-pillars. This directly exposes critical safety electronics—including the side-curtain airbags, rearview mirror sensors, forward-collision camera arrays, and steering column electrical modules—to active moisture. This creates a severe risk of sudden, catastrophic electrical short-circuits, unintended airbag deployment, or sudden loss of safety assist systems while operating the vehicle at highway speeds. The vehicle is currently leaking for a fourth time. Because the manufacturer's certified network is entirely incapable of sealing the vehicle or curing this defect, the vehicle remains an ongoing safety hazard to its occupants and other motorists on the road.

I am writing regarding the defective condition of the 2022 Nissan Pathfinder (approx. 16,431 miles) purchased on Nov 10, 2025. With the onset of spring, the A/C system has failed, blowing only ambient air. This aligns with known manufacturer defects: Jump Tube Defect (PC899/PC939): Faulty seals causing refrigerant leaks. A/C Amplifier (NTB23-033A): Irregular airflow and spontaneous surges. Notably, I reported HVAC and mechanical concerns within the 90-day warranty period. On Dec 20, 2025, I notified the dealership of whistling sounds/airflow bursts and clicking noises in the steering system. Although technician dismissed these as "normal" at the time, reporting them within the warranty period preserves my right to repair. While previous issues (loose bolts/chassis vibration) were resolved, the HVAC irregularities persist. On April 18, 2026, I returned to report the A/C failure and was denied a complimentary diagnostic, despite the vehicle being sold in a defective condition. Requested Actions: Full Diagnostic: A comprehensive, no-cost inspection of the entire HVAC system. Complete Repair: Replacement of the condenser, jump tube, seals, A/C amplifier, and related components under dealer responsibility/manufacturer goodwill. System Service: Full evacuation and recharge of refrigerant to manufacturer specs. Confirmation that the vehicle is returned in fully functional and safe condition at no cost due It was reportes during warranty period.

Hi as I was driving my car on a clear road no cars near my car all of a sudden my sunroof exploded as if it was shot my a military tank we panicked thankfully tried to maintain calm and it didn’t hurt my children and thankfully no car was around as the sound did put us at panick mode which could have resulted in a car crash from the cause of the incident

While driving at a moderate speed of 65 mph, the back portion of my panoramic sunroof spontaneously shattered. There was a very loud noises followed by rattling of the glass on the sun roof cover. I pulled over immediately and pulled the sunroof cover half way back to see a hole the size of a softball through the sun roof. There is no debris that was flying in the air, on the road, or any signs of an object hitting my car. On inspection there was no body damage from my car and when i looked into the hole of the sunroof there was no object within it. There was also no vehicles directly in front of me, only a vehicle 150 feet in front. The weather was cloudy, but no rain or wind.

I also have noticed the gurgling sound from the passenger's side when raining and/or when I have had my vehicle washed, and as of this morning 12/02/2025, I have a leak inside the cabin of my vehicle from the middle upper console and over the passenger side window. I am taking it to a windshield repair place to be inspected to see if it is an issue with the windshield or the moonroof. I will then be taking it to the Nissan dealer.

On 10/12/25, while driving on the interstate, the sunroof of our 2022 Nissan Pathfinder suddenly exploded. As of today (10/13/2025), the vehicle is available for inspection upon request. When the sunroof failed, the interior roof shade was closed. I was driving at interstate speeds with my wife and children in the vehicle. The sound of the sunroof exploding was very loud and came without warning, startling all of us - luckily, I managed to keep control of the vehicle. We could hear shards of glass bouncing around above us - had the roof shade been open, we would have had a large amount of sharp glass shards fall on us. This event happened yesterday (10/12/25), and I will be calling our dealer today (10/13/25) to confirm the issue - I have provided a photo of the sunroof, taken after we safely left the interstate. As of today (10/13/25), the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives; it has been inspected by me and my wife. There were no obvious signs of anything striking the sunroof: the only loud noise was the glass shattering, and there was no apparent damage to the fabric of the interior roof shade (which was closed when the sunroof exploded). The interstate was clear of debris when the incident took place and there were no indications of rocks, gravel, etc. Before the sunroof exploded, there were no warning lamps, messages or other symptoms of the problem prior to the failure.

The engine would shift out of drive into neutral while driving on the road. It one time shifted into park while pulling out of my driveway and left me stuck in the middle of the road for several seconds before it would allow me to shift back to drive. This has been continuous throughout. I reported to Nissan with no action from them. Sunroof leaks At 93,000 miles and regular maintenance (at home) the engine seized and they are saying sludge. I know it has been maintained so there has to be a separate cause. We had routine maintenance, the report from Nissan all along provided no engine issues or no oil pressure issues.
