ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
While attempting to accelerate my car hesitates and slows down to about 5 miles an hour. This mostly happens in the morning, but does happen in the afternoon while attempting to accelerate to pass. This issue has almost caused me to get in accidents on several occasions. I first noticed this issue when I first purchased the vehicle. I took it in and it was kept at the dealership for a week or so. When it was returned the dealer told me they couldn’t find a problem. I later took the car to another dealer and was the fuel injectors need to be cleaned but this did not fix the problem.

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.

SERVICE BRAKES, STEERING
BOTH MY WIFE AND I FEEL THAT THE HEATED STEERING WHEEL GETS TOO HOT TO COMFORTABLY HOLD CONTINUOUSLY. THIS ENCOURAGES THE DRIVER TO TURN OFF THE STEERING WHEEL HEATER WHILE DRIVING. UNFORTUNATELY, THE SWITCH IS LOCATED IN THE LOWEST BANK AT THE DRIVERS LEFT KNEE WHERE IT IS VERY DIFFICULT TO SEE. IT IS ALSO IN CLOSE PROXIMITY TO THE SWITCHES TO TURN OFF THE VEHICLE DYNAMIC CONTROL, BACK-UP COLLISION INTERVENTION AND WARNING SYSTEMS. ALL OF THE ABOVE COMBINED RESULT IN THE DRIVER HAVING TO DIRECT THEIR ATTENTION AWAY FROM THE ROAD AND TO THE LOWER CONTROL PANEL AND, IN ADDITION, MAKES IT LIKELY THAT THEY WILL INADVERTENTLY TURN OFF A VEHICLE SAFETY SYSTEM. THE SERVICE MANUAL PROVIDES A RANGE OF 68F - 86F. THE DEALER MEASURED MINE AT 120F. SINCE THIS CLOSELY MATCHED ANOTHER Q70 ON THE LOT IT WAS DEEMED "NORMAL". I SUBMIT THAT IT IS NOT AND BELIEVE THAT IT NEEDS TO BE ATTENDED TO BEFORE IT RESULTS IN AN ACCIDENT. *TR

VISIBILITY/WIPER, 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.

VIBRATION CAN BE FELT IN THE STEERING WHEEL AND THE DRIVER AND PASSENGER FRONT SEAT. TIRES WERE ROAD FORCE REBALANCED BY THE DEALER, BUT THE PROBLEM PERSISTS. SINCE IT IS AT ONLY CERTAIN SPEEDS, THE CAUSE OF THE PROBLEM HAS NOT BEEN IDENTIFIED BY THE DEALER.
