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.

Premature wear on my rear brakes. Front brakes when checked were at a level 7 out of 10 while the rear brakes at 24,000 miles were down to a 1 per one company and a 3 per Alpine Nissan. I was told it is recommended I do not drive the vehicle without getting the brakes replaced and the problem was due to my driving and all brakes wear different. If that were the case my front brakes would have gone first or been close to the same measurement. It was deemed unsafe to drive after 24,000 miles. I have 2 small children and at this point do not feel like this is a safe vehicle for me and my family to continue driving nor do I feel I need to take on the financial responsibility of replacing my rear brakes every 1-2 years due to a vehicle malfunction. If I had to slam on my brakes at any point my vehicle would skid which made me realize the significance of this issue and safety driving on the road. The only warning sign I had was a squeaking sound for about a week and I took it in immediately and found my break pads were down to a 1 measurement.

I am reporting premature and abnormal tire wear on two consecutive Nissan Pathfinder vehicles (2022 and 2024 models). In both cases, tires required replacement at low mileage (approximately 20,000–25,000 miles) despite normal driving and proper maintenance. My 2022 Pathfinder also experienced brake-related issues, which raises additional concern about potential underlying defects. The repeated pattern across multiple vehicles suggests a possible defect involving alignment, suspension, or braking systems. Premature tire wear presents a safety concern, as it can reduce traction, increase stopping distance, and raise the risk of tire failure or blowout, particularly at highway speeds. A Nissan dealership has confirmed the abnormal tire wear and recommended replacement, and previously acknowledged there may be known issues contributing to this condition. However, the issue continues to be classified as “normal wear and tear,” and no corrective action has been taken. There were no warning lights or messages prior to the issue; it was identified during routine service inspection. The vehicle and affected components are available for inspection upon request. I am requesting an investigation into whether Nissan Pathfinder vehicles have a defect contributing to premature tire wear and associated safety risks.

The car is sending off the alarm for the back seat not being buckled when there is no one back there and there is nothing on the seats, it is now also doing it where it does that but shows one of them as buckled when there’s no one in the seats

There are 2 antifreeze lines going to the back of the vehicle, they are to cool the 3rd row seats using air conditioning. Both lines were incorrectly designed so they have a repetitive failure rate of 100%. Both lines failed in March of 2025 and were replaced by Serra Nissan of Traverse City, MI. Both lines failed again and were confirmed by the dealer yesterday on 7-1-26. The first failure occurred at 8,401 miles. The second failure at 16,742. Anti freeze is spraying on the brakes of the rear passenger area, a major safety issue. Nissan does not want to spend the money to redesign the failed part design so they reinstall the same failed antifreeze lines with every repair. There is a 5 MONTH WAIT for new parts to arrive due to the massive quantity of failures. No warning lights appear during these repetitive failures. The failures are visible, you can see the antifreeze leaks all around the rear brake. And the air conditioning stops functioning in the car. Serra Nissan is very upset that Nissan Inc. is refusing to correct the failed design of the part. So the failures will occur forever.
