IllustrationWhile driving on the highway and using the hands free feature on iPhone, I said, Hey Siri, and somehow it made the automatic braking on my 2019 Infiniti Qx50 engage unexpectedly. This is not the first time it has engaged unexpectedly and there are also instances when the sensors engage without anything nearby.

On 3 different occasions while traveling over 50 mph on the highway, with no other cars around, my Qx50 automatic emergency braking initiated and stopped my car. This is a serious safety issue and I am very lucky I was not rear-ended.
The automatic braking system on my car seems to malfunction when going across the Louisiana/Mississippi bridge. As I was driving the car began to brake but it didn’t come to a complete stop. This put my safety at risk because there were cars behind me and if I would have come to a complete stop on the bridge it would have been a…

The automatic braking system on my car seems to malfunction when going across the Louisiana/Mississippi bridge. As I was driving the car began to brake but it didn’t come to a complete stop. This put my safety at risk because there were cars behind me and if I would have come to a complete stop on the bridge it would have been a terrible accident. there was a warning issued on my dash while the car was beginning to brake on the bridge.
I was driving around 30 mph crossing an intersection when the Emergency Braking system activated and caused the truck to stop. There was nothing obstructing the vehicle, nor were any pedestrians near. This is the 3rd occurence when this happened.

THE DCU HAS BEEN REPLACED 4 TIMES AND I STILL HAVE THE SAME ONGOING / UNRESOLVED PROBLEMS. I TOLD THE SERVICE MANAGER (RUDY), TO START REPLACING ALL THE SENSORS, CMS AND CAMERA AND HE REFUSED TO DO THAT. MY QX50 HAS BEEN IN FOR SERVICE FIVE TIMES (INCLUDING TODAY, 04-21-2021), FOR A TOTAL OF 6+ WEEKS. THE MECHANIC AT INFINITY, CAN'T REPLICATE ANY OF MY ONGOING PROBLEMS / UNRESOLVED PROBLEMS AND I HAVE 25 VIDEOS, SHOWING WHAT THE QX50 IS DONG AND INFINITY CAN'T FIX IT. I PAY A LOT OF MONEY FOR THE QX50 AND FOR ALL THE DRIVER SAFETY FEATURES, OTHER AMENITIES AND IT STILL CONTINUES TO FAIL MISERABLY AND DOES NOT PERFORM AS INTENDED. BECAUSE OF THESE UNRESOLVED PROBLEMS AND ONGOING ISSUES, MY WIFE REFUSES TO DRIVE IN THE QX50 WITH ME. I HAVE ASKED INFINITY TO BUY BACK THE QX50 AND THEY FLAT OUT REFUSED. I HAD TO OBTAIN A LAWYER.

DATING BACK TO NOVEMBER 2019, MY VEHICLE'S AUTOMATIC EMERGENCY BRAKING HAVE ENGAGED 3 TIMES WITHOUT REASONABLE CAUSE AT SPEEDS THAT VARY FROM 40-70 MPH. THE FIRST TWO INCIDENTS WERE ON NORMAL CITY ROADS GOING APPROXIMATELY 40-45 MPH. THE LAST INCIDENT (JUNE 2020) HAPPENED WHILE DRIVING ON A HIGHWAY, WITH NO TRAFFIC AROUND, GOING ~70 MPH AND MY VEHICLE ALMOST CAME TO A COMPLETE STOP. THE FIRST TIME I TOOK THE VEHICLE INTO THE DEALERSHIP, THEY RESET THE SYSTEM. THE MOST RECENT TIME THEY SAID THE INCIDENT HAPPENED TWICE TO TECHNICIAN AND THEIR ASSUMPTION WAS THE VEHICLE WAS NOT CLEAN ENOUGH. I FOLLOWED UP WITH INFINITI CONSUMER AFFAIRS AND THEY TOLD ME THESE INCIDENTS HAVE HAPPENED IN OTHER VEHICLES BUT DO NOT THINK THE SITUATIONS ARE RELATED. WITH THE INCIDENT NOW HAPPENING A TOTAL OF 5 TIMES (AND WHEN THE VEHICLE WAS CLEAN), I DO NOT FEEL SAFE IN THE VEHICLE AND BELIEVE THERE IS AN UNDERLYING ISSUE.

1PE23023 · Complete Loss Of Motive Power Due To Engine Failure
Opened Dec 13, 2023 · Closed Jul 18, 2025
Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
On December 13, 2023, the Office of Defects Investigation (ODI) opened PE23-023 to investigate allegations of engine failures leading to loss of motive power in model year (MY) 2021-2023 Nissan Rogue; MY 2019-2021 Nissan Altima; and MY 2019-2021 Infiniti QX50 vehicles. At that time, ODI had received 6 Vehicle Owner Questionnaires (VOQ) and multiple early warning reports, with consumers reporting engine knocking noises accompanied by a loss of engine power while driving. The investigation identified bearing failures in certain vehicles equipped with the subject 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. ODI also identified early warning reports describing thermal incidents that occurred immediately after the vehicle suffered a catastrophic engine failure. The failures were the result of a manufacturing defect in specific engine bearings (main, A-, C-, and L-link) or other engine components that may cause engine damage and potentially lead to engine failure. Engine failure can result in a loss of motive power event that can increase the risk of a crash. Engine failure might also result in a fire if internal components detach and impact the engine block creating a hole that allows engine oil to reach hot surfaces. In its April 2024, May 2024, and June 2025 responses to ODI’s information requests, Nissan provided 998 customer reports (including complaints, field reports, and legal claims) and 1,107 warranty claims related to the alleged defect. When combining ODI and manufacturer report data, there are 1,878 unique VINs that have experienced failures across all subject vehicles. In one of the early warning reports, ODI identified an incident involving a 2022 Infiniti QX55 that resulted in an engine fire following an alleged engine failure. The 2022 Infiniti QX55 was not included in the scope of this investigation but the vehicle model shares the same 4-cylinder 2.0L variable compression turbo engine. Based on the information included with the early warning report, the fire can be directly related to the alleged defect. A further review of ODI and manufacturer data, identified 12 allegations of engine compartment fires in subject vehicles; three were confirmed as directly related to the engine failure, and nine reports described an under-hood fire that occurred following a loss of power event. Additionally, ODI identified multiple reports describing an engine block crack or hole surrounded by oil residue following an engine failure. On June 27, 2025, Nissan submitted recall 25V-437 involving 443,899 MY 2021-2023 Nissan Rogue, MY 2019-2021 Nissan Altima; MY 2019-2021 Infiniti QX50; and 2022 Infiniti QX55 vehicles. The recall remedy provides the dealer instructions to inspect the engine oil pan for the presence of specific metal debris. For customers with the 3-cylinder 1.5L VC-Turbo engine, if no debris is detected during the inspection, dealers will replace the oil pan gasket, engine oil, and reprogram the vehicle’s Engine Control Module (ECM). For customers with the 4-cylinder 2.0L VC-Turbo engine, if no debris is detected, dealers will replace the engine oil. In the case where specific debris is detected and confirmed by Nissan Powertrain Call Center, dealers will be instructed to replace the engine. In addition, Nissan will extend the vehicle warranty to 10 years and 120,000 miles for the recall subject vehicle population after the dealer performs the inspection. Nissan has implemented multiple corrective actions to address the identified manufacturing defects of certain engine block internal components. In view of the recall action (25V437) taken by Nissan, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.
