2010 Infiniti G
Engine not specified
| 13000 mi | Knocking noise when engine warmed up....After much testing, engine oil changed to synthetic from factory recommended regular oil. Problem has been resolved but oil change will now cost 2x as much. |

Low battery (changed)- ECM reprogram at N/C - charge to diagnose |
| 51360 mi C $700 |
new accessory drive belt required |
| 93000 mi US $180 |
Cleaned throttle bodies (first time this was done) to alleviate occasional stalling problem at start-up. Symptom: car started but then revs dropped too far and car stalled. This cleaning absolutely fixed the problem. |
| 57000 mi | warm start stall |
| 77900 mi US $60 |
Throttle body needed to be cleaned, car was shaking while in drive and stopped |
| 89000 mi US $600 |
Water pump failing, was losing coolant. |
| 19000 mi | Fuel line damper had to be replaced. Caused loud idle. |
| 27200 mi | Check engine light on, gas cap replaced |
| 68000 mi | Ses light came on. Code was p0106. Dealer said needed ecm upgrade. No charge to me. |
| 85000 mi US $2500 |
Error code P0021 -- Intake Valve Timing Control and low oil pressure. Apparently the entire valve body has to be replaced rather than just the faulty gasket (which would lower the labor to 8hrs instead of 18.5). |
| 88500 mi US $300 |
I had a check engine light on. Error code pointed to a service bulletin saying the MAF sensor was causing it and the ECU had to be updated to fix the issue. |
| 100800 mi US $280 |
I went in for service due to a check engine warning light being on. The issue was related to ignition timing, which required an update to the ECU. ECU update couldn't be downloaded at the dealer, which extended the time. Update performed. $280. Engine drive belt showing wear. Replaced. $180. |
| 108000 mi US $65 |
Crack in the coolant reservoir. Reservoir replaced. |
| 128000 mi | Exhaust was showing signs of age and wear. Replaced from the catalytic converters, back. The Catalytic converters will probably also need replacing within the next year. |
2010 Infiniti G 4dr Sedan
328-horsepower 3.7L V6 6-speed manual RWD
| 64800 mi US $370 |
Brought car in for sporadic P300, P306 codes. Dealer replaced fouled spark plug #1 & didn't find any other problems. I realized this was the reason why it was running "boggy" from low RPM. 1st noticed the "bogginess" around 30k miles |
| 108000 mi | P0300 code persisted from 2013 repair trip. Dealer (via Infiniti Consumer Affairs) replaced: Infamous rear timing chain gasket on the VQ37VHR motor, intake cam sprocket, MAF sensor, coolant temp sensor, & H2O pump (leaking). Code persists. |
| 110000 mi | Dealer replaced intake manifold gasket, fuel injectors, & ignition coil packs for persistent P0300 code. Code came back about 2 weeks later and appears more frequently as well. |
