Air bags

52 reports2 crashes
“My vin # [XXX] comes up as a 2 door 2011 infiniti g37. Mine is a 4 door. The problem is the air bag light started to blink and the airbag light would show passenger airbag. I've researched enough about the takata air bag recall and the 2011 infiniti g37 is a part of that recall. It's mind boggling just thinking about the dangers of my vehicle that I need to get to and from work daily as well putting anyone on the passenger seat. I don't even feel safe driving the vehicle anymore. What can be done, its obvious it's not working properly.”

Electrical system

14 reports2 crashes1 fire
“While car was in operation, Intelligent Key System warning light came on (yellow "KEY" light). After turning off car engine, car will no longer start up. Key fob locks and unlocks doors, but car will not start. Prior to this incident there were no indications of a problem, no wornings. Upon investigation and research, the issue is related to a "Steering Lock Failure", and is widely known for years by other owners, repair shops, and Nissan and Infiniti. Nissan has addressed the issue by recalling and repairing the failure, however Infiniti has ignored the issue even though it is the same part (and same company). Infiniti must be made to repair the failure, as Nissan has done.”

Structure

13 reports1 crash
“The sunroof’s drain ports clogging up is a known common issue to Infiniti dealers, as I have learned while taking my car in after the entire dashboard & electronics shorted out. The mechanic told me this is a common occurrence during the rainy season. Water may intrude the body through the clogged ports and the first location the water goes, happens to be the lower passenger side which ALSO happens to be the location of the body control module (BCM). The car has stopped operating on me in the middle of driving, and also wouldn’t allow me to get out of the gear I was in. What could be a $50 - $150 repair turns into a $2500 - $2800 repair.”

Vehicle speed control

10 reports5 crashes
“I was having gas mileage issues and had an engine light come on one day. I checked it for it to come up with mass air flow sensor code. I had them replaced. Once I replaced them I noticed I still had the light and mileage issues. I did some research and found out you need to reprogram the sensors at a dealership after replacement. I scheduled an appointment at Infiniti of Akron and they reprogrammed them. I left and a couple hours of driving later the acceleration is worse and mileage is bad. The engine light comes back on. I call back they check my ECU and said I was missing an update. They couldn’t do the update due to their systems being down at the time and told me they would call me when they were ready. I left to head home. I hopped on the highway towards my house. After about 10 minutes of driving my car begins to slow down to a complete halt and stalls right in rush hour traffic. I had no where to safely pull over. There was no shoulder available due to construction. I immediately called 911 to assist me to get an emergency tow. I eventually ended up being rear ended by a car. A fire lieutenant stayed with me for about 2 hours to ensure I was safe until…”

“I have been having issues with my passenger airbag warning light. The issue is warning light will not go out. I took my vehicle to an Infiniti dealer for a diagnostic. Dealer found code DTC B1018 OCS unit failure. Much to my disbelief and, dealer recommends new passenger side air bag diagnoses module and lower seat frame before further diagnosis. What really angered me was the price to repair a safety issue on this vehicle that wasn't caused by an accident or repair . The quoted module price was $1275.00, price for lower seat frame is $7695.00. Note, this is the price for parts and didn't include labor. At that point, I didn't ask what the labor cost was because I was flabbergasted and taken aback by the the excessively high price for repair. After reading 100's of forums, many are having the same issue with their Infinities and other Nissan Vehicles. Infinity and NHTSA must be aware of this massive problem and Infiniti/Nissan needs to correct this flaw in engineering at the companies expense. We as consumers who pay a lot for these vehicles should be protected. My concern is I have lupus and Arthritis and have chronic pain daily and need my car for numerous…”

Power train

8 reports1 crash
“Hydraulic clutch fluid overheating causing catastrophic clutch piston failure resulting in not being able to engage, shift, or most importantly disengage the current drive gear in motion. The safety condition of not being able to disengage the operation of the vehicle puts the occupants at risk by limiting the ability to prevent collision. I have experienced this failure approximately every 20,000 miles, leaving the vehicle stranded on the highway with each occurrence of the event.”
