2020 NISSAN PATHFINDER Engine Problems

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...

My 202 pathfinder started misfiring with sever knocking, Nissan said there is metal saving in my oil which is caused because of the long block engine failure and timing chain loosening. I had my oil changes done every 4K, and I also had the fluids flushed twice in 5 years because of excessive build up. How does this happen.

Electrical issues with my car including AC. Timing belt chain went and gasket covers. Continuous issue with this vehicle.

There's been a loss of power when accelerating, engine has made an odd noise during startup and occasionally a knocking noise when driven longer than a 10 mins. Dealership said there's metal in the oil pan. I saw an article today that said only nissan three and four cylinder vehicles have these issues but my pathfinder has the same problems.

Engine misfiring on left side due to faulty timing chains. Car would not start at times, and engine light flashing. Safety was at risk due to engine being unreliable, misfiring, and we were advised it could possibly stall/cut-out while driving. Problem confirmed by independent service center. Dealer service center would not diagnose without taking engine apart at our expense, they recommended replacing the whole engine, and the car is only 3 years own. There is a know issue with the timing chains on this model of vehicle, yet they did nothing to resolve the problem.

Back in nov 2022 my car had to go in the shop due to its jerking, shuddering, shaking while accelerating. Then suddenly just stopped wouldn’t let me accelerate turn break nothing locked up luckily I was able to pull over and shut off the car because it was still on during this time. I had just picked my young kids up from elementary school. The dealer ship had us pay the deductible and told us it was the ecm they replaced it and we were 0 dollars out of pocket due to warranty. Well 2023 may it started showing low oil pressure light then it would go off the engine light comes on then goes off and while the lights are coming on and going off the car with shake and studder. Got an oil change it it had stopped. Now July 2023 the engine light is one constantly as...

I drove from Pine Bluff, AR to Memphis, TENN in pouring rain. There were many tractor trailers on the highway throwing water back on my vehicle. When I got into Memphis, my vehicle shut down and would not re-start for several hours. I believe this to be a safety issue because if I had driven a little farther and it suddenly shut down in traffic, this would have caused a terrible accident.

Engine failure while driving. Abnormal engine oil consumption. Oil level dropped without warning and without any warning lights from the vehicle. The vehicle oil level as checked 1 day prior to failure.

Engine pinging/knocking and engine hesitation / surging most obvious in second gear steady throttle around 2k rpm. Doesn't matter what gas is used. Engine hesitation and pinging/knocking is getting worse. NISSAN states its normal operation.

TL* THE CONTACT OWNS A 2020 NISSAN PATHFINDER. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT ILLUMINATED INTERMITTENTLY. THE CONTACT TOOK THE VEHICLE TO COURTESY NISSAN (1777 N CENTRAL EXPY, RICHARDSON, TX 75080, (972) 231-2600) AND WAS INFORMED THAT THE OXYGEN SENSOR FAILED AND NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 19,700.*DT

WHEN DRIVING OR IDLING YOU GET A SMELL OF ANTIFREEZE INSIDE THE DRIVERS COMPARTMENT. DEALER SAID THE ONLY WAY TO FIX WAS TO GET THE HEATING AND COOLING SYSTEM ON RECIRCULATING AND NOT FRESH AIR. THIS IS CONSTANT PROBLEM NO MATTER THE TWHAT THE TEMP AT URGE ISOUTSIDE.
