Since my car had about 45000 miles on the odometer, it has been producing a thick white smoke, not only upon starting the car from a cold start, but also after longer distance trips over 30 miles. After having taken it to the dealership multiple times, their response has been that they cannot recreate the problem and most likely it is from engine sludge due to not maintaining the regular oil change schedule. After having shown the dealership the timely maintanence schedule I had performed on the car over the years, they continued to claim that there is no problem with the car. After the standard warranty had run out one year later and upon taking it to the dealership they claim that I need to replace the head gasket and it would cost me $3500. In addition to the avoidance game they played over that year, in my opinion they were simply pushing back the maintenance until the warranty ran out. This is a common problem with this specific car and the low mileage and I know of at least one more family experiencing this problem. There needs to be a thorough investigation on not only the problem with the engine of this car, but the potential of unscrupulous business practices of the dealerships.
THIS PROBLEMATIC INFINITI QX60 HAD FAILED ONCE AGAIN WHILE I WAS ON THE HIGHWAY. IT'S JUST DEAD AND THE ENGINE REFUSED TO START. I HAD TO CALL THE TOW TRUCK TO DROP OFF AT THE KINGS INFINITI AUTO SHOP FOR REPAIR. FIRST, IT WAS A HUGE INCONVENIENCE THAT THEY COULDN'T TAKE A LOOK AT THE VEHICLE UNTIL A WEEK LATER. SECOND, NO ONE EVER OFFERED ME A LOANER CAR TO TAKE HOME AND HAS STILL DENIED THIS REQUEST. WE DEPEND ON THIS FOR WORK AND SCHOOL. THIRD, JUST TODAY I WAS INFORMED BY THE INFINITI TECHNICIAN THAT I WOULD BE RESPONSIBLE FOR THE REPAIR FEES OF $13,000 DUE TO ENGINE FAILURE! SERIOUSLY?! THIS IS ABSOLUTELY RIDICULOUS AND I HAVE NEVER HEARD OF IT FROM ANYWHERE. TO ME THIS IS TOTALLY UNACCEPTABLE AND I STRONGLY BELIEVE IT IS THE MANUFACTURER GUILTY OF THE CAR ISSUES AND SUSPECTING THIS IS A CAR DEALER FRAUD. $13,000 REPAIR COST IS RIDICULOUSLY HIGH, YOU COULD PUT DOWN A DOWN PAYMENT FOR A CONDO OR TO BUY A LOWER GRADE NISSAN SENDRA. I AM EXTREMELY DISAPPOINTED AT THE UNRELIABILITY OF THIS VEHICLE AND THE COMPANY IN GENERAL. I'VE BEEN LEASING VEHICLES FROM NUMEROUS CAR BRANDS FOR THE LAST 10 YEARS AND HAVE NEVER EXPERIENCED AN ISSUE EVEN REMOTELY TEDIOUS AND FRUSTRATING AS THIS. WE'VE ALREADY DEALT WITH THE MINOR ISSUES OURSELVES BUT HOW COULD WE BE EXPECTED TO BE RESPONSIBLE FOR AN ENGINE FAILURE THAT ISN'T OUR FAULT? AS I HAD MENTIONED ABOVE, I HAVE REGULARLY KEPT UP THE MAINTENANCE SCHEDULE AS LISTED ON THE CAR MANUAL FOR ALL TYPES OF OIL CHANGE, CHANGING ENGINE FILTER, ETC. I'M ATTACHING ALL THE RECEIPTS WE COULD FIND FOR THE MAINTENANCE SERVICES THAT WERE DONE FROM THE LAST COUPLE OF YEARS. IT IS IMPOSSIBLE THAT THE ENGINE COULD FAIL DUE TO "LACK OF MAINTENANCE".
