NHTSA Complaint #11673155 — 2018 NISSAN MURANO

NHTSA Vehicle Safety Complaint – 2018 Nissan Murano Submitted by: [XXX] Vehicle: 2018 Nissan Murano VIN: [XXX] Mileage at time of issue: Approx. 93,500 miles Location: Albuquerque, NM Date of issue onset: [XXX] Summary of the Problem: Shortly after my vehicle was serviced at a Nissan dealership, it began exhibiting serious mechanical and electrical issues. These include: - Transmission jerking and slipping between gears - Uncommanded RPM surging while accelerating - Occasional loss of power, particularly at highway speeds - Dashboard flickering, resetting, and other electrical irregularities - Brake caliper drag and significantly reduced gas mileage Third-Party Diagnosis: A certified independent repair shop reported the following: - Transmission malfunction (needs full replacement) - Dragging brake caliper - Engine overfilled with oil - Erratic RPM behavior Despite these findings, the dealership dismissed all concerns and returned the vehicle unrepaired, with no adequate documentation of the work performed. Additional Concerns: I believe the vehicle was accessed and tampered with while at the dealership. After their service: - My dashboard and door panels were visibly unsealed or repositioned - The vehicle was held for extended periods (multiple weeks) - No paperwork was provided showing any actual mechanical repairs I have before-and-after photographs and text messages confirming this timeline and change in condition. Safety Impact: The transmission failure, RPM spikes, and braking inconsistencies make the vehicle unsafe to drive. These problems pose a significant crash risk, especially in highway traffic or while merging. I’m submitting this report to NHTSA to contribute to any ongoing investigations related to this vehicle make/model and to help prevent further consumer risk. Additional Observation – Abnormal Heat After Driving After driving the vehicle, extreme heat can be felt rising from underneath the dr INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
