“My car was going good for 3 years and out of nowhere it stopped getting gas or throttle like it should and it's been sitting for a week now... Ima have to get checked or something but out of nowhere my car would start but not throttle properly and would slip and all my lights would go in my car..”

“I got my car in april 2013 not a year yet. I was at work when they said the light started to blink and then the alarm started to go off when the security came by around it was smoking and on fire it was coming from the hood. The police and fire station said they think it was a electric problems. I really don't know what I should do now.”

“Stereo audio cut off and A/C turned on to full blast. Console controls and temperature controls stopped working. Turned off car then on to see if it would fix the issue, but once it was on the A/C turned to full blast again and controls don't work. This issue has my motor running harder bc the A/C is on causing my car to overheat while driving uphill. Ever since the controls have not worked constantly for over a year.”

“The car simply died after pulling on to a busy highway. It would not start for several minutes. After taking the car to the infinity dealership I was informed that it was a cam shift sensor failure. Not just one, but two sensors. I understand that there was a recall for this model but I cannot get the infinity to comply with this recall and the subsequently charged me $500+ to replace the two fouled parts. Very disappointing.”

“Hello, my 2003 Infiniti G35 coupe is experiencing the exact issue that NHTSA campaign number:03v455000 (Infiniti recall no. R3021) describes for the crank/cam shaft position sensors. My car will literally just die while driving at any given time! My steering wheel locks up, and I have to pull over with a stiff steering wheel to turn my car off & restart it. Sometimes, the car won't start becuase of the same issue. However, my local Infiniti dealer and the Infiniti customer service line have both informed me that they cannot fix this issue becuase my VIN was not listed on that recall. …”
