“The service engine light came on, and I brought the vehicle to thousand oaks Infiniti where I regularly have the vehicle serviced. The diagnosis was a bank 2 catalytic convertor failure. Based on my research, this is a very common problem with the car and it is just a matter of time that the other catalytic convertor will also need to be replaced.”

NHTSA complaint #11131472, filed 2018-09, 143,000 miles

“Timing chain was loosened and was rubbing against another part make a loud noise while sitting and driving. Thankfully I stopped in to have it checked out. The service department said it was ready to break at anytime. Thankfully nothing happen to me, kids, and husband on the highway. Frightening to think of losing control of a vehicle while driving 65 MPH. There was a recall on time chains for the same year, but my VIN # was not covered. It should have been covered. I have had it to the dealership several times for normal upkeep. …”

“The vehicle was completely dead and would not start when battery was jumped. Battery was replaced once it was discovered that the original battery was completely dead. Once the vehicle started , the engine light was visible on the dash. The vehicle was making a very loud humming sound coming from under the hood. The sound got louder and intensified as the rpms increased.”

NHTSA complaint #11316183, filed 2020-03, 75,000 miles

“Loud whistling/whining sound from the motor at start up. Extreme loss of power when starting up a grade or to get up to speed on the interstate causing fear of rear end collision. It appears to be a common issue with this vehicle that results in a timing chain or catalytic converter repair, costing several thousand dollars. It appears Infiniti is aware of the problem but won't issue a recall for obvious reasons. This vehicle is now virtually inoperable as it is not safe to be on the road until it is fixed.”
