Engine failure in my vehicle equipped with the VQ35DD engine, which I believe is the result of a widespread and well-documented design defect involving internal sludge buildup. I have owned this vehicle for over five years and have followed the recommended routine maintenance schedule, including on-time oil changes using high-quality oil. At no point during any inspection, service, or maintenance appointment was I informed of any sludge buildup or concerns with the engine. Only after a serious mechanical failure did the Nissan servicing dealership claim the engine was full of sludge, subsequently recommending an engine replacement. Despite my diligence in maintaining the vehicle, I am now facing an engine replacement that was entirely unexpected and has created a safety risk due to loss of motive power. This could have resulted in a serious accident, and I believe this issue merits urgent and transparent attention. Upon researching this issue, I found dozens of similar complaints from...

PCV Valve hose clogging rendering system useless and resulting in sludge buildup in engine. The sludge buildup causes issues with timing chain lubrication and ultimately destroys the guides causing excessive engine rattling, aluminum flakes in the engine. Causes loss of power, numerous different engine codes, and ultimately catastrophic failure of engine. Hise collapses within itself and prevents proper crankcase ventilation. See attached pictures.

My Nissan pathfinder has consistently had a AC compressor unit replacement several times. There is OBVIOUSLY a sealing issue on this part /vehicle. It’s absolutely unacceptable to replace a AC compressor unit 3 times within the 5 years of owning this vehicle.
