NHTSA complaint #11656442

Owner complaint summary

Description of the Problem: For the past three years, my vehicle has experienced intermittent and sudden loss of power while driving, including on the highway. The issue is ongoing and has not been resolved despite having the throttle body replaced three separate times, totaling approximately $4,500 in repairs. Each replacement has resulted in the exact same malfunction: the car enters limp mode, drastically reducing power, which is especially dangerous when my children are in the vehicle. Component/Inspection: The issue appears to involve the throttle body and possibly the CVT transmission or related electrical system. The component has been replaced multiple times and is available for inspection if needed. Safety Risk: This malfunction puts my safety and the safety of my passengers at significant risk, particularly when driving at high speeds or in heavy traffic. The car's sudden loss of power makes it difficult to accelerate or maintain speed, which could easily lead to a collision/serious injury. Problem Reproduced/Confirmed: Yes. The problem has been witnessed and confirmed by Midas of Palm Bay, FL and Nissan of Melbourne, FL. Manufacturer Involvement: I reached out to Nissan, but they refused to assist with the repairs or offer any support. Warning Signs/Symptoms: Before the failure, the check engine light comes on, followed by a warning message that reads “Engine Malfunction.” Immediately after, the vehicle loses power and cannot accelerate normally.
