Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
Driving down highway 421 in wilkesboro, nc on a 45 MPH section of the highway, merged over into the turning lane to turn left across two lanes of traffic. Waited for a break in traffic, upon a break in traffic tried to accelerate to cross traffic, as vehicle started to accelerate it stalled in middle of road. Wife and children in car started screaming. Traffic nice enough not to run into us. Had car towed to local automotive repair shop. Found that this is a common problem for the 5.6 litter nissan/ infiniti engine. One of the timing gears for the left bank stopped rotating some how. This side of the engine timing system also powers the fuel pump so that you cannot even limp across the road on half the engine. It just stops right where you are. You have no steering no breaking and no propulsion. This is a dangerous situation and the manufacture should be held responsible for the design and lack of quality of the engine.
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.
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. Should there have been a recall, the service dept would have caught it. They agreed this morning as well.
Catalyst problem p0420 p0420. Seen same vehicles being recalled.

The manufacturer stated that there were no recalls and referenced technical service bulletin: 16-015; however, it expi*bfred in february of 2018. The failure mileage was 120,000. *bf
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.
Hear abnormal noises from the engine sound like rattle or ticking
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.
