2016 Infiniti QX50

Purchased vehicle on 4/23/23 from Carmax. Discovered horn was not working 5/10 when a truck swerved into my lane on the freeway. Carmax refused to refund money under 30 day guarantee stating I drove over 1500 miles. Prior to purchasing I signed documents stating the car was in perfect condition after 3 point inspection , horn included . They scheduled a appointment at the end of the month leaving me with no transportation to get to work . After complaining to the BBB they denied anything was wrong with the car, even after doing a appraisal on 6/10 where I stated the horn was not functioning. I took the car for a third party diagnostic and the mechanic determined a defective horn relay and spiral cable . I have not driven this car at all since 5/13 except 6/10 when I attempted to sell it back to the dealership twice.

This is the 3rd instance of my car rolling backwards down the driveway. Both the first and second instances of uncontrolled rolling happened in 2016. Only the second instance was caught on camera. I shared the video with Infiniti and was instructed to bring the car in for an inspection. I went in for the inspection in December 2016 and they reported that there were no issues (despite video evidence). Today, December 2, 2022, the car (while gear shifted into park) again rolled down the driveway, across a street and hit my neighbor's house. This was all caught on video as well. I posted the video on the manufacturers social media site. See below for the email I sent to the dealership after they contacted me. I've also uploaded the videos to YouTube because they're in MP4 format and I'm unaware of how to convert them to the format required for this submission. The titles of the videos are: Infiniti QX50 Rolling Backwards December 2016 and Infiniti QX50 Rolling Backwards December 2022. Both were published today, December 2, 2022.

The Display / Navigation screen does not always light up. Some time it works when you start the car. Other times it tries for a awhile be fore it starts to work. When it lights up everything from what I can tell works normally. When it does not light up. The AC works by its self, but you can not turn it off or adjust it. The warning sensors work, but Camera does not work. Radio does not work. Because we do not live close to an Infiniti dealer. I took it to a North Strand Nissan dealer 2592 Highway 9 Little River, SC 29566 phone 843-390-7777. They performed a diagnosis and found internal failure in the system. They told us they would need to start with replacing radio unit and then check further at a cost of $6,500. Yet when they moved the car outside to park it everything worked for them. And when we picked up the car everything work until we turned it off. We just drove it 10 hours on a trip. Sometimes it worked when starting up the car. Other times it took an hour or so for it to work. The safety problems is when the screen flashes trying to start at night. It is distracting. Also backup camera does not work if the screen does not light up. Car has 39,000 miles on it Thanks

THERE IS SOMETHING WRONG WITH EITHER THE ACCELERATION, ELECTRICAL OR THROTTLE. WHILE PARKING THE VEHICLE AND APPLYING THE BREAKS, THE VEHICLE SPEED FORWARD AT HIGH SPEED AND WOULD NOT STOP EVEN WITH APPLYING THE BREAKS. IT CRASHED ME AND MY DAUGHTER INTO A BRICK BUILDING AT HIGH SPEED. THE WITNESS SAID HE HAD NEVER SEEN ANYTHING LIKE IT BEFORE AND HE WAS A MECHANIC AND AUTO BODY SPECIALIST. HE SAID WE WENT FROM ALMOST IN THE STOP POSITION TO HIGH SPEED LIKE A CRASH TEST DUMMY VEHICLE. THIS ALL OCCURRED IN A SMALL PARKING LOT IN THE CITY. THE INSURANCE COMPANY DEEMED IT A TOTAL LOSS BECAUSE THE DAMAGES WERE OVER 85% OF THE CARS VALUE. THE WITNESS AND URGENT CARE FACILITY SAID WE ARE LUCKY TO BE ALIVE. I TOOK THE VEHICLE TO THE DEALERSHIP IN FEBRUARY OR MARCH 2020 REGARDING THE VEHICLES ACCELERATION. THE SERVICE REP I WORKED WITH WAS CONDESCENDING AND TRIED TO MAKE ME THINK IT WAS ALL IN MY HEAD AND TOLD ME THERE WAS NOTHING WRONG WITH THE VEHICLE. HE DROVE IT AROUND A FEW BLOCKS WITH ME IN IT AND SAID THERE WAS NOTHING WRONG. I KEPT TELLING HIM THERE IS SOMETHING WRONG BECAUSE IT WOULD EITHER LOSE POWER OR JERK FORWARD OUT OF NOWHERE. THIS WAS A CPO VEHICLE SO I DID NOT EXPECT TO BE TAKING IT IN FOR SERVICE ONLY A COUPLE OF MONTHS AFTER PURCHASING IT. *TR

TL* THE CONTACT OWNS A 2016 INFINITI QX50. CONTACT STATED THAT WHILE TURNING INTO A PARKING FACILITY THE RPM REVVED UP WITHOUT WARNING. THE CONTACT SHIFTED THE VEHICLE INTO NEUTRAL AND THE VEHICLE RETURNED TO NORMAL OPERATION. THE VEHICLE WAS TAKEN TO GEORGE HARTE INFINITI LOCATED AT (1076 S. COLONY DRIVE, WALLINGFORD, CT 06492, (203) 495-6700) WHERE THE VEHICLE WAS TEST DRIVEN AND DIAGNOSED HOWEVER, THE TECHNICIAN WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE RECEIVED AN UNKNOWN REPAIR HOWEVER, THE FAILURE RECURRED INTERMITTENTLY. THE VEHICLE WAS SCHEDULED TO BE DIAGNOSED WHICH WAS STILL PENDING. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 26,000.

FROM A COLD START,DRIVING VEHICLE A SHORT DISTANCE APPROX.( 1 MILE ) PULLING INTO A PARKING SPACE. STEP ON BRAKE PEDAL, ENGINE IDLE INCREASES MAKING YOU PRESS HARDER ON THE BRAKE PEDAL. THIS EXCESSIVE BRAKING TO STOP IS A SAFETY ISSUE. AT FIRST I THOUGHT I WAS STEPPING ON THE BRAKE AND GAS PEDAL AT THE SAME TIME. I FOUND THIS WAS NOT THE CASE. THE VEHICLE WANTS TO LURCH FORWARD . THIS HAS HAPPENED SEVERAL TIMES. THIS EXCESSIVE BRAKING HAS ALSO HAPPENED AT A TRAFFIC SIGNAL LIGHT. CONCERN IS ALWAYS TO BE READY WITH A HEAVY FOOT ON THE BRAKE PEDAL. SINCE I'M A NEW OWNER OF THIS PREOWNED VEHICLE, I WASN'T SURE IF THIS WAS A MINOR PROBLEM ,THE VEHICLE HAS LESS THAN 26K MILES. I CALLED THE DEALER ,WAS TOLD NO PROBLEMS WERE EVER NOTED FOR THIS EXCESSIVE BRAKING ON THE 2016 INFINITI QX50 MODELS. THEY ARE GOING TO CHECK OUT THE VEHICLE AND SEE IF THE PROBLEM CAN BE DUPLICATED BY THEIR TECH'S. I FOUND PREVIOUS INFINITI VEHICLES BACK AROUND 2008 WERE NOTED IN A SERVICE BULLETIN AS TO EXCESSIVE BRAKING FROM INCREASE RPM PERHAPS FROM ICV CONTROL VALVE OR IAC FOR ERRATIC IDLE. I WILL WAIT ON THE RESULTS FROM THE DEALER ON THEIR FINDINGS.

FUEL GAUGE INACCURATE - WHEN FILLED IT SHOWS ABOUT 306 MILE RANGE, I.E. ABOUT 15.2 MPG FOR THE 20 GAL TANK. AFTER DRIVING FOR 20-30 MILES IT SHOWS 360 MILE RANGE WHICH IS MORE ACCURATE - WHETHER STATIONERY OR MOVING. THE FUEL ECONOMY INDICATOR SHOWS 18.8 MPG IN THIS EXAMPLE. ON THE FREEWAY THE INDICATOR MAY SHOW 21.0 MPG BUT THE SAME PROBLEM IS THERE.

THE CHILD SEAT VEHICLE LATCH ANCHORS ARE PRACTICALLY INACCESSIBLE. THE ANCHORS ARE POSITIONED UNDER THE SEAT CAUSING GREAT DIFFICULTY IN ATTACHING THE CHILD SEAT TO THE BRACKETS. THIS HAS CAUSED INJURY TO THE PERSON ATTEMPTING TO ATTACH THE LATCH TO THE ANCHOR. ALSO IT HAS RESULTED IN IMPROPERLY SECURING THE CHILD SEAT. IT SEEMS TO BE A FACTORY DEFECT, WHEREAS THE ANCHOR WHICH IS SHAPED LIKE AN "L" BRACKET WAS INSTALLED UPSIDE DOWN. THE LOCATION OF THESE ANCHORS ARE UNDER THE SEAT RATHER THAN BETWEEN THE GAP OF THE SEAT CUSHION AND THE BACK CUSHION ARE VERY UNREASONABLE TO USE. ATTEMPTING TO UTILIZE THE ANCHOR HAS CAUSED UNDUE AMOUNT OF TIME, STRESS AND INJURY. I HAVE REPORTED THIS ISSUE TO THE DEALER.
