Nissan North America issued recalls for 643,000 Rogue SUVs Thursday after identifying defects in throttle bodies and engine bearings. Owners reported symptoms including hesitation during acceleration and unusual engine noises, according to National Highway Traffic Safety Administration filings.

The larger recall covers 515,417 vehicles from model years 2021-2024 for throttle body gear failures. Dealers will inspect and replace faulty throttle bodies free of charge, plus update engine control software. Affected Rogues include those built at Nissan’s Smyrna, Tennessee, and Kyushu, Japan plants.

Separate from that action, Nissan recalled 127,436 Rogues from 2023-2024 over damaged connecting rod bearings. These can lead to engine damage, oil leaks and potential fires if oil contacts hot surfaces. Remedies involve engine inspections, bearing replacements if needed and software reprogramming.

Drivers might notice reduced power when accelerating, especially on highways. Some report check engine lights, vibrations or burning oil smells. Officials said no crashes or injuries tie directly to these faults, but loss of propulsion heightens crash risks during merges or passes.

Not every Rogue faces both issues. Production dates vary: throttle recall hits vehicles from November 2020 to February 2024; bearing recall targets September 2022 to March 2024 output. Owners should enter their 17-digit vehicle identification number at NHTSA.gov/recalls or NissanUSA.com to confirm involvement.

Dealers prioritize safety checks. Throttle repairs may take under an hour for software alone, longer with parts swaps. Bearing inspections could extend to several hours or days if engine work follows. Nissan notified owners by mail starting next month; appointments book quickly in high-demand areas like California and Texas.

Such recalls stem from warranty claims and testing. Nissan’s data showed throttle gears cracking under stress, disrupting air-fuel mix and triggering limp mode. Bearings wore prematurely from manufacturing debris, per the filings. Both defects emerged in late 2023 probes.

Owners waitlisting repairs should watch for warnings. Pull over safely at signs of power loss, smoke or odd noises. Drive cautiously, avoiding high-speed maneuvers until serviced. Repairs carry no cost; keep service records for warranty proof.

Rogue ranks among America’s top-selling SUVs, with over 300,000 units moved yearly. This action highlights rising complexity in electronic throttles and precision engines. Similar recalls hit Toyota and Honda recently over powertrain glitches.

Federal regulators mandate fixes within 60 days of notice. Nissan reports 95% completion rates on prior campaigns. Owners facing delays can contact Nissan’s recall hotline at 1-800-867-7669.
