Air bags

46 reports4 crashes2 fires
“The contact owns a 2005 Infiniti G35. The contact stated that the seat failed to recline. The service engine light was illuminated. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 10V175000 (Air Bags, Seats). The vehicle was taken to an independent mechanic who determined that the cause was a faulty fuse. The fuse was replaced, but the failure recurred. The contact called the local dealer, who confirmed the recall repair was previously completed. The vehicle was not diagnosed or repaired. The contact called another local dealer, Douglas Infiniti (430 Morris Ave, Summit, NJ 07901), but there was no response. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 190,000.”

Engine

“The fuel gauge is not reading correctly, and I have to rely on knowing my mileage and how much I last filled in my tank. I have to keep the car running longer than necessary to even duplicate the problem, and when I do the gas gauge just suddenly starts dropping. And if for some reason I even let my gas get low enough to have the low fuel lamp come on, it's almost too late and I barely make it to a gas station. I have not had the issue reproduced/confirmed by any independent servicer. I have seen in many G35 forums that this is an issue that has not had a recall yet. All of the other models for Nissan/Infiniti 2005 were recalled for the fuel sensor in 2010, but not the G35/G37 model. If this keeps happening I will eventually be involved in an accident when my gas runs out unexpectedly on the highway.”

“THE THIRD BRAKE LIGHT INSIDE THE REAR GLASS DOES NOT WORK AND NEVER HAS. IT IS NOT JUST MINE THAT DOESN'T EITHER. ALMOST ALL G35'S WITHOUT OEM SPOILER HAVE THIS ISSUE.”

“05 G35 AUTO SEDAN. GAS GAUGE NOT READING AMOUNT OF GAS CORRECTLY FOR THE LAST 5 YEARS. WASTED OVER 900$ IN PARTS. NEW AND USED TO TRY AND GET IT FIXED. NOTHING WORKED. REPLACED FUEL PUMP, LEVEL SENDER UNITS AND INSTRUMENT CLUSTERS 3 TIME. UPSET NHTSA AND MFR. ARE NOT RECALLING TO FIX THIS ISSUES. A LOT OF VEHICLES HAVING SAME LIFE THREATENING PROBLEMS. FOLKS IN FORUMS AND YOUTUBE AND SOCIAL MEDIAS ALL TALKING ABOUT IT, BUT YET NO ONE'S DOING ANYTHING. AFTER THREE TIMES MY CAR STALLED ON ME I HAD ENOUGH, BECAUSE IT'S MATTER OF TIME WHEN THE NEXT ONE END IN DEADLY CONSEQUENCES. 1ST TIME CAR RAN OUT OF GAS ON HIGHWAY 99 AND A CAR BEHIND ME ALMOST HIT ME FROM BEHIND. THE GAS AT THE TIME WAS READING 1/4 AND NO LOW GAS INDICATOR LIGHTS UP. CAR SHUDDER WITH NO ACCELERATION WHEN GAS PEDAL IS PRESS DOWN. THEN ALL ELECTRICAL AND POWER WENT OUT WITH NO CONTROL EXCEPT FOR HARD STEERING. I MANAGED TO PULL TO SHOULDER FROM THE CAR POOL LANE BEFORE CAR DIED. LUCKILY THERE WEREN'T MANY CARS ON THE FREEWAY THAT MOMENT IT STARTED DYING ON ME. 2ND TIME IT HAPPENED ON THE MAIN STREET AND SAME SYMPTOMS AS FIRST TIME AS ABOVE. THEN I LOOKED AT MY GAS GAUGE AND IT SAYS 1/2 FULL! BUT…”

“I RAN OUT OF GAS ON MY COMMUTE HOME FROM WORK. MY GAS HAND READ A QUARTER OF A TANK WHEN I COMPLETELY RAN OUT OF GAS LEAVING ME STRANDED ON THE INTERSTATE. SINCE THIS HAPPENED I'VE DONE SOME RESEARCH AND IT'S A COMMON PROBLEM FOR G35 INFINITI'S. THEY GAVE A RECALL ON THE NISSAN AND INFINITI SUV FOR THIS EXACT PROBLEM SAME YEAR MY 2005 INFINITI WAS MADE. THE G35 SEDAN AND COUPE SHOULD BE INCLUDED IN THIS RECALL.”
