As anyone experienced this? I was literally driving down the road, coming to a stop light when the engine turned off like a light switch. The radio, lights and gauges stayed on? After coming to a stop and waving cars around me I rolled it backwards into a gas station where I was greeted by the owner of Draco Performance, Barry Bodine. I'm in NC so I'm pretty sure this guy was related to the famous NASCAR driver Jeff Bodine. Anyway I got out, went to the trunk and turned the power switch off for 30 seconds, got back in the car…no luck! The car would turn over fine just wouldn't fire? Barry then suggested we leave the switch off for 5 minutes for all the power to drain off the ECU...it worked! It fired right up after we gave it time.

Has this happened to anyone else? Thankfully this happened at 45 MPH and not on the interstate at 80 mph or on a curvy ass road because the power steering goes when the car dies.

I do have FD DBW & ECU. Not sure this has something to do with it or not? I did switch the DBW from aggressive to nonaggressive while the power switch was off. Not sure if this is linked together.

Any thoughts??

Thanks, Justin

Justin,
Sorry to hear that. It is scary stuff. I have not exactly had that happen to me but once my car engine just shut down coming to a traffic light once. (from about 5mph) It only happened once and the car started back up. I would take in it and get it looked at...

Justin,

No reported or related DBW / ECM issues from customers. I know that you had a few wiring issues with the car though, perhaps this is related. I'd keep my eye on it!

Best Regards,

I've seen the shutdown issue at low speeds before, in my case (it scared the hell out of me) was just a dirty MAF sensor due to the intake sucking dirty air.

I don't think this is related to the DBW or ECU by FD, if you wire something wrongly then you'd probably get a CEL or at least it would be a permanent problem.

You can buy CFC MAF cleaner locally I'm sure. Just try a local auto parts shop, but I'd be careful not to damage it either, it's delicate.

Best Regards,

Do I need to "clean" the dirty MAF sensor?
Yes, as Jeff mentioned above there is a cleaning spray that you can use. Mine was very dirty, the wire was completely black and had a lot of dirt stuck on it.

PS:
the MAF works by heating a small wire and calculates how fast it cools down by the intake air, thus calculating how much air in sucked in. There are other types of MAF sensors which work differently.

I just had this exact same problem today.. 2008 Granturismo... stopped at a stop light and and wasn't really paying attention, all of a sudden, it was real quiet and I noticed the engine wasn't on anymore!! I then put the car into park and turned the key, started right back up again and didn't give me anymore problems.... Is this a common problem? Was it a MAF sensor problem for the original poster of the thread?

I've seen issues before where the clutch position sensor gets confused and does not know at what position the t/o bearing and clutch is at and shuts the car down.

This happened to me once, but the circumstances were different than yours - in my case, it was at very low speeds (parking lot), stopped to wait for some pedestrians to cross in front of me, when I started to move forward again, the vehicle stalled. Took me 2-3 tries to get it to start up again... didn't have to reset the battery, though, but the Check Engine Light stayed on all the way home (car ran fine, though).

Eddie Rodriguez noticed my post & replied that it might be the Clutch Position Sensor, and he was right (as VT DMC also suggested, above) - OBD reader pulled a code to that effect. This was a few weeks ago, and I haven't had it happen since then, so fingers crossed!

I don't know if this may be the same issue as yours or not, since the situation was different (you were driving right along, I was barely starting to move forward from a stop).

I had same thing happen today exiting a lot in Boston. I had the same thing happen with my MB 430 E several years ago and the dealer said to check the gas cap to ensure it was tight. I had not twisted the cap on Maserati far enough, didn't want to break it, on the last fill. Got home and filled the tank and gave a "three click" twist and the light went off. . We will see...

This happened to me 3 times today. First time idling, 2nd time idling again and 3rd time just stopped at the lights.
Engine cut off and also the dash and all power. Just as it cuts off the red light on battery was showing. Engine light came on.
I re-started the car each time and it came back up.
I don't know if this has anything to do today but it was in manual rather than auto (been lazy the past week). Also I possibly noticed that the even in manual it used to shift automatically up. (which it shouldn't)
I switched it back to auto and drove it 30 mins to mechanics without any issues. Engine light also disappeared.

Could it be a fault detected by the sensor and shuts down the car? It just got back from mechanics 2 days ago got the thumbs up that the engine and the rest of the car is fine.

Any feedback is greatly appreciated.

Regards;
Saturn

Shop said it was a clutch error.
Clutch at 80%.
I didn't realize a clutch error code could actually shut off engine and power.
Anyone else ever had this symptom.
I get this error in manual and no issues with auto.

Since it has to be done the clutch is getting replaced at 27k miles.

If you mean Clutch Position Sensor, then yes (see my post, above).

When you say "clutch is at 80%", do you mean your clutch has 80% life left, or has 80% wear?

DD is right Saturn, the clutch errors are related to the clutch position. If the TCU doesn't have a clear and concise understanding of where the T/O is it will shut down the engine to avoid causing damage or mis-engaging and causing an accident.

Clutch position sensor errors are also the most common "failure" in the F1 system.

DesertDawg:
Its at 80% wear. Only 20% left. In auto it seems there is no issues.



ECSofVirginia:
When switched to manual or auto-off on the CC or F1 it seems the issue come back on. I do not know why it would manifest more on manual mode. I was thinking it would manifest in automatic.


So now its at the shop and the clutch is getting replaced. :(
ouch....

If you're still having trouble with it, have it checked for a faulty electrical relay. That could be creating the intermittent shut-offs.

It was the clutch. Once the clutch was replaced the issue went away.

Thanks.
