“The contact owns a 2013 Infiniti QX56. The contact stated that intermittently while parked, and while driving at various speeds, the rear of the vehicle was sagging. No warning lights were illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the air shocks and compressor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and the contact was informed that the warranty had expired. The approximate failure mileage was 40,000.

“SUV WOULD NOT START SO HAD TO GET A JUMP. 1 WEEK LATER SAME THING. HAD BATTERY TESTED BUT WAS NOT BAD AND IT HAD JUST BEEN REPLACED BY DEALER IN 2019. 1 WEEK LATER AGAIN SUV WOULD NOT START. GOT A JUMP AND TOOK TO JBA INFINITI IN ELLICOTT CITY, MD WHO CHARGED THE BATTERY FOR 2 HOURS. 2 WEEKS LATER, SUV IS HESITATING TO START. I REFUSE TO PAY ANOTHER $186 FOR THEM TO DIAGNOSE AND THEN RECHARGE THE BATTERY AGAIN. AFTER SOME RESEARCH IT LOOKS LIKE OTHERS ARE HAVING THIS SAME ISSUE. NEXT, CATALYTIC CONVERTERS. SUV IS 8 YEARS OLD AND JBA INFINITI IS TELLING ME I NEED TO REPLACE THEM @ A COST OF $7500. THIS IS RIDICULOUS.....I DON'T HAVE LOSS OF POWER BUT I SO GET THE "ROTTEN EGG" SMELL SOMETIMES. I WOULD THINK THIS PART WOULD BE COVERED UNDER EMISSION WARRANTY FOR AT LEAST 15 YEARS. I HAVE 142000 MILES ON IT.”
