Complaint Timeline
Chronological view of owner reports
Engine manufactured with porous block causing coolant to mix with oil resulting in bearing failure. Vehicle has less than 60k miles and I have seen numerous reports on Infiniti Q50/Q60 forums with people having the exact same issue. Some vehicles have had multiple engine replacements. Vehicle out of warranty due to age. Have not been able to drive vehicle for over a year and was told I should report issue to the government since Infiniti has not stepped up and done a voluntary recall.
Internal engine mechanical issues, infiniti of bridgewater diagnosis. The engine cut off midway while driving on the highway. Vehicle received an engine replacement 1-2 years ago from Infiniti of edison (ray catena) who were shut down after the replacement. There was absolutely no warnings or problems before hand.
The contact owns a 2016 Infiniti Q50. The contact stated while driving at various speeds, the vehicle jerked before stalling. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the engine was faulty. After replacing the engine, the failure persisted. The contact stated that the vehicle was repaired several times before the engine was replaced. The manufacturer was not yet notified of the failure. The approximate failure mileage was 60,000.
WE TOOK OUR CAR IN FOR ITS FIRST OIL CHANGE AT A OIL LUBE BUSINESS AND AFTERWARD OUR CAR'S ENGINE SEIZED UP ABOUT 4 MILES DOWN THE ROAD, AND COMPLETELY DESTROYED ITSELF. AFTER INVESTIGATING, IT SEEMS THE OIL TECH MAY HAVE DAMAGED THE OIL FILTER ASSEMBLY'S DELICATE END TIP PIECE UNBEKNOWNST TO HIM. IT IS INCONCLUSIVE IF HE DAMAGED IT OR BROKE IT OFF. AT A LATER DATE THIS OIL LUBE BUSINESS GAVE US AN INFINITI TBS THEY GOT FROM OUR INFINITI DEALERSHIP, THAT THEY NOR I, HAD EVER SEEN. ALSO IT DOES NOT SEEM TO BE FILED WITH ANYONE NOR THE NHTSA. THE TBS CLAIMS THAT THIS PART BREAKS VERY EASILY IF NOT PROPERLY HANDLED. ALSO WHEN OUR PROBLEM WAS DIAGNOSED BY AN INFINITI TECH, HE TOLD US THIS PART BREAKS SO OFTEN, THAT THEY HAVE TO KEEP THE ITEM IN STOCK IN THEIR PARTS DEPARTMENT. HE ALSO SAID THE PART WAS MISSING FROM THE ENGINE IMPLYING THAT THE OIL LUBE BUSINESS HAD BROKEN IT OFF, AND KNOWINGLY PUT A BROKEN PART BACK IN. BUT PER VIDEO THAT WAS GIVEN TO US, THAT IS INCONCLUSIVE. ALL WE SEE IN THE VIDEO IS THE OIL TECH HOLDING THE PART FROM THE DELICATE END OF THE OIL FILTER ASSEMBLY. PER THE INFINITI TBS AND THEIR TECH'S OWN WORDS TO US, THE PROBLEM STEMS FROM THE FIRST OIL CHANGE WHERE THE FILTER IS VERY HARD TO GET OFF THE FIRST TIME. HENCE MANY PEOPLE TEND TO OVER STRESS THE PART AND THE VERY DELICATE PLASTIC END TIP WILL GET DAMAGED OR BREAK OFF DURING THE OIL CHANGE. I BELIEVE THIS PART IS DEFECTIVE AND BUILT VERY WEAK WITH A PLASTIC MATERIAL THAT CAN'T HANDLE ANY STRESS ON IT. IF DURING AN OIL CHANGE BY A DIY OR ANOTHER OIL LUBE BUSINESS LIKE "JIFFY LUBE" WHO DON'T KNOW THIS TBS EXISTS (WHICH WE DID NOT BECAUSE INFINITI KEPT IT FOR THEIR OWN TECHS), THEN THERE IS A POTENTIAL FOR THE DAMAGED PART TO BE REINSERTED IN THE ENGINE WHERE IT COMPLETELY COMES OFF INSIDE AND RUINS THE ENTIRE ENGINE. THIS COULD BE A LIFE THREATENING HAZARD ON THE ROAD IF ENGINE COMES APART!
