- What is wrong
- On certain passenger vehicles, the circuit board for the crank position sensor or cam position sensor may have an improper solder joint due to solder deformation caused by heat stress accelerated by the existence of flux residue during the soldering process.
- Risk
- This could cause the "service engine soon" warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation, which could result in a crash.
- Remedy
- Dealers will replace the crank position sensors. Camshaft position sensor(s), and in some cases, the variable timing control sensor(s). Vehicles involved in a previous recall campaign, 01v357, are also included in this new campaign. The replacement sensors used in that campaign are also affected. Owner notification began on december 22, 2003. Owners should contact nissan at 1‑800‑647‑7261 or infiniti at 1‑800‑662‑6200.

The car engine cuts off / stalls while driving. This has happened multiple times. When driving on highway, the engine stops running, the car loses all power, and it is very difficult to restart the car. I had the car inspected and the local mechanic stated the crankshaft sensor/ camshaft censor is not working properly and he believed this was on recall, but Infiniti stated that my car is not covered. This is extremely dangerous - call stalls in the middle of the road with no power at all.
Twice while driving approximately 70 mph on the freeway, the engine shut off without warning and the service engine soon warning indicator illuminated. The vehicle coasted. There was no shoulder to pull over to. I put it in neutral and it restarted. The vehicle was taken to an independent mechanic where it was diagnosed that the camshaft and crank sensor failed. I looked online and saw a recall for the cam shaft and crank sensors for the, 2003 Infiniti G35. However, when I called, I was told that my vin was not included in the recall.

Hello, my 2003 infiniti g35 coupe is experiencing the exact issue that the federal safety agency 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. I bought this car around 6-7 years ago, so I would not have even been able to take it in to get fixed since they noted it was only 2003 for a certain time. This just recently started happening a few months ago, and I finally found the exact issue on your website. I verified that my cars computer noted that those specific sensors are bad! I'm very upset with infiniti not even caring to help one of their customers for a major safety and liability issue! This keeps happening over and over at random, and I'm honestly nervous to drive my car. This could easily pose danger to others or myself if the car does this while driving in the future! Please help!
Burns oil at 5 quarts a week or more. Piston rings are defective. Common for this car I've read and there was a recall that infiniti issued but this has not included my vehicle. Suspension also wears down brand new tires in less than 3 months. My boyfriend has the exact same car and this is a problem with his vehicle also.
