“Infiniti needs to recall the timing chain galley gaskets. My 2009 g37xs sedan recently blew the galley gaskets and it seems as if this is a common problem and is a very expensive fix. Recall this issue please I always use 93 gas. Always use mobil 1 full synthetic oil, and always do all maintenance on the car on time. I'm shocked and aggravated that this issue happened and Infiniti did not recall it.”

There was a vehicle in front over me going about 65 MPH and the furthest left lane was moving closer to my speed. When there was an opening, I signaled and began changing lanes when the vehicle began jerking and losing power.

NHTSA complaint #11354477, filed 2020-09, 186,000 miles“My 2009 Infiniti G37, third owner, has always had its scheduled maintenances through Infiniti. Took the car in because of a rattle sound coming from the undercarriage. Dealership diagnosed it as internal engine damage. No indication from the vehicle that their is a problem with the engine. There has never been a check engine light detected or any other symptom - other than the rattle sound - that would discern an engine problem when driving the vehicle. Infiniti consumer affairs will not help me, and say that I have no recourse. …”
