-When braking while hybrid and engine system are attemping to determine the power draw the vehicle will propel forward increasing momentum of vehicle rather than braking. -Vehicle is available for inspection. -This issue can cause collision due to the sudden undesired propulsion of the vehicle, as well as addition unnecssary use of the braking system. -Dealer states this is normal condition. -Vehicle has only been inspected by dealer. -There are NO warning signs, indicators, or alerts. Issue first started around 35,000 miles. -In addition the drivetrain might also affect the ability to propel forward. While in slow speeds (10 mph and below) the vehicle the vehicle will stutter making take off difficult from complete stop. Additionally, vehicle stutters just the same while braking to come to a stop (10 mph and below) making it difficult to navigate a safe stop.

ENGINE HAS ROUGH IDLE WHILE IN PARK. EVEN AFTER THE FOLLOWING MAINTENANCE WAS DONE. REPLACING SPARK PLUGS, ENGINE SOFTWARE UPDATE, COOLANT FLUSH, POWER STEERING FLUSH, FUEL SYSTEM CLEAN, NEW MASS AIR FLOW SENSORS BOTH SIDES, SERPENTINE BELT, ALL NEW GASKETS ON TOP PART OF ENGINE, VALVE COVER, INTAKE MANIFOLD, SPARK PLUG TUBE SEALS. FLUSHED REAR AND REAR DIFF AND TRANSMISSION. STEERING IS HEAVY TO TURN. THE COLDER IT IS OUTSIDE THE WORSE THE ENGINE SHAKES. THROTTLE RESPONSE IS DELAYED AT TIMES. TRANSMISSION SHIFTS HARD THE WORSE THE ENGINE SHAKES. COLDER IT IS THE SLOWER THE WINDOWS ROLL UP AND DOWN ALONG WITH THE WIPERS. ENGINE DROPS RPM WHEN TURNING WHEEL WHILE IN PARK. WHEN DRIVING ENGINE DROPS ABOUT 100 - 200 RPM THEN KEEPS GOING BACK UP UNDER ACCELERATION BUT CAUSES TRANSMISSION TO SHIFT HARD. THIS PROBLEM CAUSES THE OUTPUT SHAFT SEAL TO BREAK AND REAR WHEEL SPEED SENSORS WERE...

FIRST INSTANCE: WHILE DRIVING ON THE HIGHWAY GOING 60MPH MY CAR POWERED DOWN, PREVENTING ME FROM CONTROLLING THE CAR. THE GAUGES AND LIGHTS INSIDE THE CAR WENT DARK AND MPH WENT TO 0. I LOST ELECTRICAL POWER AND AFTER 1 MINUTE THE CAR IS BACK TO NORMAL. SECOND INSTANCE: AS I WAS PULLING INTO A DRIVEWAY AND WENT OVER A BUMP THE CAR LOST POWER AND POWERED DOWN, I NATURALLY PRESSED THE GAS BEFORE I UNDERSTOOD WHAT WAS WRONG, THE CAR POWERS BACK UP AS I'M PRESSING THE GAS AND CAUSED ME TO ALMOST HIT ANOTHER CAR.

MY POWER STEERING BELT SNAPPED OFF. PRIOR TO THAT, MY BRAKE PEDAL WAS LOOSE ENOUGH TO MOVE IT UP AND DOWN ROUGHLY A 1/4 OF AN INCH WITH MY FOOT. THE ONLY WAY TO ENGAGE THE CRUISE CONTROL WAS TO HOLD THE BRAKE PEDAL UP WITH MY FOOT, THEN IN ORDER TO KEEP THE CRUISE CONTROL ENGAGED WAS TO KEEP HOLDING THE BRAKE PEDAL UP WITH MY FOOT BECAUSE IT WOULD SENSE THAT THE DRIVER SLIGHTLY TAPPED THE BRAKE PEDAL TO DISENGAGE IT IF I STOPPED HOLDING IT UP MANUALLY. I HAD TO HAVE THE BRAKE PEDAL BOLT TIGHTENED. IT HAS HAPPENED AGAIN AND I CAN'T REACH THE BOLT, SO I HAVE TO PAY TO HAVE IT FIXED AGAIN ALONG WITH THE OTHER ISSUES. THE OTHER ISSUE IS MY A/C BLEND DOOR IS NOT OPERATING, WHICH IS CAUSING THE TWO DRIVER SIDE A/C VENTS TO BLOW WARM AIR OUT OF...

DURING 20 DEGREE F, I DROVE MY CAR WITH NO ISSUES TO A RETAIL STORE, PARKED IT IN A PARKING LOT. AFTER SHOPPING, RETURNED TO MY CAR & STARTED IT UP, PUT IN REVERSE, STARTED BACKING UP, THEN SEVERAL MALFUNCTION LIGHTS LIT UP ON THE CAR'S DASH & THE STEERING WHEEL LOCKED ALL OF A SUDDEN. I COULD NOT TURN THE STEERING WHEEL. I COULD ONLY MOVE THE CAR FORWARD & BACKWARD & THIS IS ALL WHILE THE CAR IS POWERED ON. I HAD TO HAVE THE CAR TOWED TO THE DEALERSHIP. IN PAST HISTORY, THERE HAS BEEN 2 OTHER STEERING RECALLS (ELECTRIC POWER ASSIST SYSTEM & ADAPTIVE STEERING PARTS) ON THIS SAME MAKE/MODEL,& YEAR. THE DEALERSHIP SERVICE TEAM TOLD ME ON 1/22/19 & THE ISSUE WITH MY CAR WAS THE CHASSIS CONTROL MODULE (THE BRAIN OF THE STEERING WHEEL) & A LANE DEPARTURE MALFUNCTION & THE COST OF REPAIR...

ON SEVERAL OCCASIONS WHILE DRIVING MY CAR, IT HAS LOCKED UP ON ME. I HAVE TAKEN THE CAR BACK TO THE DEALERSHIP THREE TIMES FOR THIS SAME ISSUE. THE LAST TIME I TOOK IT IN BECAUSE MY CAR LOCKED UP ON ME AFTER COMING OFF AN HIGHWAY AND I WAS HIT BY ANOTHER CAR. I TOOK IT BACK TO INFINITI WHO CLAIMED THEY COULD NOT DUPLICATE THIS ISSUE. EVEN THOUGH I POINTED THEM TO SCORES AND SCORES OF SIMILAR ISSUES BEING REPORTED ON THE INTERNET. INFINITI'S RESPONSE WAS "ANYONE CAN WRITE ANYTHING ON THE INTERNET". I THOUGHT THIS COMMENT WAS INSENSITIVE AND DOWNRIGHT RIDICULOUS. EVEN THOUGH ANYONE CAN WRITE ANYTHING ON THE INTERNET, MOST PEOPLE WOULD NOT GET ON THE INTERNET TO COMPLAIN ABOUT A PROBLEM WITH THEIR CAR THAT WAS NOT TRUE - WHAT WOULD THEY GET OUT OF IT??INFINITI'S CAVALIER ATTITUDE HAS SHOCKED ME SINCE MY FAMILY HAVE...

I LIVE IN A ONE FAMILY HOUSE WITH AN ATTACHED GARAGE. MY WIFE PARKED THE CAR,WITH 1/3 OF A TANK OF GAS,IN OUR GARAGE ABOUT 6:30 PM ON AUGUST 17. SHE THOUGHT SHE HAD PUSHED THE BUTTON TO TURN OFF THE ENGINE, AND EXITED THE CAR TAKING THE SMART KEY WITH HER. ABOUT 9 THE NEXT MORNING, WHILE WALKING MY DOG, I FELT HEAT COMING FROM THE GARAGE AND OPENED THE DOOR. IT WAS VERY HOT TO TOUCH. I THEN TOUCHED THE CAR AND BURNED MY HAND. I CALLED OUR LOCAL FIRE DEPARTMENT AND THEY PULLED THE CAR OUT OF THE GARAGE. THE CAR WAS SO HOT, A CD IN THE DOOR COMPARTMENT MELTED. THE FIREMEN EXPLAINED THAT MY WIFE AND I AND OUR DOG, COULD VERY EASILY HAVE BEEN KILLED BY CARBON MONOXIDE AND THE ENTIRE STRUCTURE COULD HAVE BURNED FROM THE HEAT. I HAVE SINCE LEARNED THAT WHAT...
