NHTSA complaint #11758582

Owner complaint summary

My 2022 Nissan Rogue has entered reduced-power/limp mode approximately nine times. The specific component causing the malfunction has not been identified. The vehicle is available for inspection upon request. When the malfunction occurs, the vehicle displays a malfunction/reduced-power warning and substantially reduces available engine power. Several occurrences happened during a long-distance trip involving highway, mountain, and desert driving. The unexpected reduction in power creates a safety concern during highway travel, merging, passing, climbing grades, or travel in remote areas. The problem is intermittent and has not been successfully reproduced by an authorized Nissan dealership. I presented the vehicle to a Nissan dealer and reported the repeated events while the vehicle had approximately 56,500 miles and remained below Nissan's 60,000-mile powertrain warranty mileage limit. The dealership advised that it could not diagnose the problem unless the malfunction occurs again with an active diagnostic code. I have also reported the problem to Nissan Consumer Affairs. The underlying cause remains unidentified and the vehicle has not been repaired for this condition. Warning messages appear when the malfunction occurs. During the long-distance trip, diagnostic codes were cleared to restore vehicle operation. The vehicle would then operate normally for a period before unexpectedly entering reduced-power mode again. My primary concern is that after approximately nine occurrences, I still have no diagnosis or assurance that the condition will not recur during highway operation or another situation where maintaining vehicle power is necessary for safe operation.
