When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2015 Infiniti Q70

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2014539 10,434 units in Canada

Fuel System

On certain vehicles, the fuel pressure sensor connected to the engine fuel delivery rail may not have been sufficiently tightened during vehicle assembly. Should the pressure sensor loosen, fuel could leak past a gasket used in the connection between the sensor and the rail. Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury. Correction: Dealers will inspect the pressure sensor and tighten to specification. Note: This is an expansion of recall 2012-074. Vehicles that were repaired under the previous campaign are not affected because that remedy would have corrected the subject condition.

Recall 2014415 511 units in Canada

Powertrain

On certain hybrid vehicles, a defect in engine control module programming could cause a gradual throttle increase without driver input, which could cause vehicle speed to increase. This could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will update vehicle software. Note: Applying the brake would allow the vehicle to be slowed or stopped.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

AIR BAGS

Driver side airbag deployed as I was turning the corner leaving me with no visual of pedestrians. The deployment resulted in lacerations on my forearm and a knot on my head with a busted lip. My vehicle is technically not drivable because my seatbelts are locked. I am also afraid of driving my vehicle due to the other airbags deploying on my family out of no where. There were no prior lights or warnings to this incident.

VEHICLE SPEED CONTROL

CAR WILL STOP ACCELERATING WITH NO WARNINGS THEN WILL START BACK MOVE WHEN YOU LET THE SIT FOR AND HOUR. ENGINE LIGHT WILL NOT LIGHT UP WHEN THE INCIDENT HAPPENED SO THE PROBLEM CAN NOT BE DIAGNOSED UNTIL THE ENGINE COME ON. HOWEVER WHEN THE ENGINE LIGHT DOES COME YOU CAN TAKE TO DEALERSHIP AND THEY WILL TELL THAT THE TRANSMISSION SPEED SENSORS NEED TO BE REPLACED IN WHICH THE SENSOR IS LOCATED INSIDE THE TRANSMISSION AND IN CONJUNCTION TO THAT IT IS RECOMMENDED THAT THE VALVE BODY SHOULD BE REPLACED ALSO. THIS HAS BEEN A PROBLEM WITH A LOT OF THE INFINITI'S WITH YEARS RANGING FROM 2014-2019 WITH 3.7 LITER ENGINE. THIS PROBLEM SHOULD BE RESOLVED BECAUSE THE CAR CAN SUDDENLY STOP MOVE AT HIGH SPEEDS AND CAUSE AND ACCIDENT. PLEASE TAKE A GOOD LOOK AT THIS RECALL AAMCO TRANSMISSION HAVE HAD HUNDREDS OF INFINITI'S WITH THE SAME PROBLEM AND THEY CAN NOT REPAIR SO THEY WILL SEND YOU TO THE DEALERSHIP FOR REPAIRS IN WHICH IT WILL COST THE CONSUMER 3,000 PLUS TO FIX THE PROBLEM AND THEY WILL RECOMMEND THAT YOU SHOULD GET THE TRANSMISSION REPLACED INSTEAD OF REPAIRING IT AND MOST OF THE VEHICLES ARE HAVING THIS PROBLEM WITH LOW MILEAGE.

EXTERIOR LIGHTING

HEADLAMPS LOW BEAMS DO NOT ILLUMINATE PROPERLY. THE IS ABSOLUTELY NO ILLUMINATION ABOVE A VERY LOW HORIZONTAL PLANE WHEN GOING DOWN A HILL OR UP A HILL. IN SOME CASES, THERE IS NO LIGHT VISIBLE BEYOND 30-40 FEET. THIS CREATES AN EXTREMELY DANGEROUS SITUATION WHEN NAVIGATION HILLY ROADS. IN FACT IT IS DOWNRIGHT SCARY TO DRIVE THIS CAR AT NIGHT. SPOKE TO DEALER AND THEY ADJUSTED THE BEAMS AS HIGH AS THEY COULD, BUT THIS DID NOT HELP. JUST LAST NIGHT I ALMOST HIT A DEER. I COULD NOT SEE FAR ENOUGH IN FRONT TO THE CAR. LUCKILY, I WAS DRIVING SLOWLY AND I WAS ABLE TO STOP IN TIME.
