Why Did My Z, Keep Revving? Video.
 

I've tried to tell a lot of you that I've been having a lot of problems with my 2009 370Z and my 2009 Infiniti FX. While my FX is in the shop for the 3rd week getting it's dashboard ripped apart... (Video on my channel) I took the Z back out since the roads have been dry in Wisconsin.


I felt like I was driving a Toyota with the accelerator stuck. I first noticed it when I was coming off the highway to an intersection. My car would not slow down without hard braking. Come to find out, when I came to a stop, it would just start revving up. The video is further proof that I'm not making things up. I didn't touch that gas pedal. It would really bake my clutch when I'd go to take off. Was the accelerator stuck? You tell me. My floor mat wasn't even close to the gas pedal. I checked it over and over. I even pulled it back 2" to make sure. I'm having some really bad luck with these cars.

Perhaps you are cursed due to being a weatherman? jk :) Have you had the car/SUV at the dealer enough times in the required period to qualify as a lemon?

Good luck with everything, and let us know how it turns out...

This is Unreal...
 

Yeah, call it a curse. Who made Nissan's throttle? Is it CTS? My car wouldn't stop revving! Is it a Toyota?

Try re-booting the car (battery disconnect for a few minutes)

I actually shut the car off twice at two different intersections. Restarted, same thing. I know, I should reconnect the battery, but really ModShack? Why would it do this to me in the first place? What if I had an automatic? At least I have the luxury of pushing the clutch in. Torque converters? Good luck. I pulled hard with the brake on. I do respect your comment, but by the time at at each intersection, it's too late. I don't have the tools to get out and pull off a battery teminal to fix it while I'm sitting at a stoplight.

You need to reset it anyways... just go out and do it now. The system might just need a hard restart and that could clear your issue.

If not, I would take the car to the dealership and show them these videos.

This is a potential safety issue, so I don't think they would send you off without a fix. The throttle assembly needs to be inspected (could be an issue with the hardware there) and the ECU needs to be checked... maybe a software glitch. Either way, you need to take it in and demand they fix it!

Complaining definitely isn't going to help any... take it in! If I was your service manager I would assure you we would not give you the car back until we resolved the issue... and I'd make sure you had a loaded loaner car provided free of charge for as long as it took to repair!

Sorry to hear it. Quick question, if you take the car off the "S Mode", can you replicate such behavior?

That was the Z saying "Its too damn cold out for this sh#t!! Get me back home!"

Since it was in neutral with the car stopped, I don't think the S mode would change anything. If the car's not moving, SynchroRev shouldn't do anything. It's just a guess, but either way. If I'm walking out of the car, it should idle. It was in neutral.

SynchroRev was the only thing that helped me.

Wow, Thats a bad run. My mom has a 2009 Fx35 and I have my 370 and both have been flawless cars, even here in the Utah cold.

I would take it to the nissan dealership or if you have the ability inspect the cables actuating the throttle, there is a possibility that water got in them and froze causing them to stick open. But its just a guess.

Ummm....I didn't mean do it in the middle of an intersection. Do it at home tonight. The only way to clear the memory and a potential Computer scramble is to power down the car (not just tun it off). If it doesn't recover, get it to the dealer as advised above..

It's "drive by wire" so no cabes involved. Totally electronic. The VVEL also does a lot of throttling on the car, not just the throttle bodies. Several potential areas that could be causing this.. If a re-set doesn't do it, the dealers diagnostic machine will certainly pinpoint the fault.

I didn't either. I said go out now... assuming he's on the boards at home, not in the middle of an intersection.

If you weren't implicating that I suggested a bat disco in the intersection then I just was confused by the double quote. :tiphat:

You have a Yaris in wolf's clothing...
