POWER TRAIN, ENGINE
My 2023 Nissan Rogue with the 1.5L VC-Turbo engine has repeatedly displayed the “Engine Malfunction Power Reduced Service Now” warning, causing reduced engine power and creating a safety risk when accelerating or merging into traffic. We took the vehicle to the dealership to have the ECM reprogrammed (which the recall suggested), but the issue has persisted. According to the Nissan Certified Technician, the vehicle has diagnostic code P210B, and the dealership recommended a valve replacement costing approximately $5,000. Given known engine defects affecting certain Nissan VC-Turbo engines, we are concerned the dealership is addressing the symptoms rather than the underlying problem of a potentially failing engine. We are concerned this could allow a serious engine defect to go unresolved while leaving us responsible for substantial repair costs. I request that NHTSA investigate this issue for potential safety defects and determine whether further recall action is necessary.

Vehicle Mileage: 82,775 Component Affected: Engine / Cooling System / Fuel/Emission System (EGR Cooler) My 2023 Nissan Rogue equipped with the 1.5L VC-Turbo engine suffered a catastrophic internal engine failure, leaving the vehicle completely inoperable and causing a dangerous situation due to severe engine overheating (Diagnostic Trouble Code P1217). A professional inspection and pressure test by a certified technician (Repair Order #38473) revealed that the Exhaust Gas Recirculation (EGR) cooler completely failed to hold pressure. As a direct result of this internal component failure, coolant drained entirely from the reservoir and rapidly flooded Cylinder 2. The coolant cross-contaminated the engine lubrication system, mixing water into the engine oil and permanently destroying the internal integrity of the long block engine assembly. The vehicle now requires a completely new long block engine, turbocharger, catalytic converter, and EGR cooler. Nissa is currently aware of widespread, premature catastrophic engine failures across this exact 2023 Rogue 1.5L VC-Turbo engine line, having issued a massive engine replacement recall and 10-year/120,000-mile warranty extension in March 2026 (NHTSA Campaign 26V080) for main crankshaft bearing failures. However, Nissan is currently exploiting a technical loophole to deny coverage for my vehicle. Because the root cause of my engine's destruction was an internal EGR cooler pressure failure rather than a crankshaft bearing failure, Nissan claims it is exempt from covering the repair despite the final mechanical damage, safety risk, and engine destruction being completely identical. Nissan should not be permitted to avoid liability for a known, systemic powertrain defect by restricting recall remedies to a singular root cause when adjacent components like the EGR cooler are causing identical, catastrophic engine failures well under their self-declared 120,000-mile engine lifespan. It is identical to what has been happening.

I am reporting repeated loss of engine power and subsequent engine failure involving my 2023 Nissan Rogue SV equipped with the 1.5L VC-Turbo engine. On February 3, 2026, at 151,975 miles, Nissan of Boerne performed recall R25D1 and campaign PA447. Following that service, the vehicle experienced repeated loss of power and limp-mode conditions, creating a safety concern while driving because the vehicle could not accelerate normally. In April 2026, World Car Nissan documented an engine malfunction complaint accompanied by forward and rear collision warning lights. In May–June 2026, at 163,589 miles, Nissan of Boerne confirmed trouble code P2564 and diagnosed a turbocharger wastegate stuck open. The dealership replaced the turbocharger assembly. In September 2026, at 172,431 miles, the vehicle again experienced a severe loss of acceleration. The engine RPM increased when pressing the accelerator, but the vehicle would not accelerate normally. The dealership documented the complaint as loss of power without warning lights and replaced the three-way catalytic converter. In October 2026, Nissan of Boerne diagnosed a blown head gasket, coolant leaking into cylinder 3, overheating, and trouble code P04FA (EGR over-temperature). The dealership recommended replacing the engine long block for $7,166.52. The vehicle is currently inoperable. These problems have been examined by authorized Nissan dealerships, and the service invoices document the diagnoses and repairs. The vehicle's current condition may be available for inspection through the dealership, subject to confirmation. I am concerned about the recurring loss of power, the potential danger of being unable to accelerate in traffic, and whether the vehicle was adequately inspected under applicable VC-Turbo engine safety recalls. Nissan Consumer Affairs advised that the recall had been completed and declined further assistance.
ENGINE
Complete engine failure due to leaky EGR valve at 74k miles. Vehicle overheated suddenly in the middle of busy traffic, needing to stop the vehicle in the middle of the road. Problem has been confirmed by an independent contractor. Vehicle has not been inspected by manufacturer or dealership, due to high cost of diagnosis and car being just out of warranty. There was no warning lamp or symptoms before failure.
ENGINE AND ENGINE COOLING
The contact owns a 2023 Nissan Rogue. While driving at 45 MPH, the engine experienced reduced power and hesitated while accelerating. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic and the dealer on several occasions, and the throttle body, HVAC air intake and refrigerant, mass airflow, intercooler pipe, battery, idle air control (IAC) valve, rack and pinion, serpentine belt, and pressure sensor were replaced, and the 3-part fuel system was cleaned; however, the failure persisted. The vehicle was taken back to the independent mechanic, who determined that an unknown part needed to be replaced again. The manufacturer was notified of the failure by email and on the website. The failure mileage was approximately 120,000.
