Randomly shuts off

Hi.I had the same problem. Car would drive jerky, would hesitate at low speeds and eventually shut off for no reason and without any error code stored while stopping or trying a slow turn, vehicle would also have significant increase in fuel consumption. Stealer made me pay for software update, replace ignition switch, throttle service etc.

Expect the following to happen soon: car eventually shuts off again but pretty soon you'll see finally an error code P0406 (EGR Valve high output ) and your check engline light will come on ( it will turn-off again after 4x starting car, but error code will still be stored) in simple words: your EGR Valve soon says bye-bye. But: for as long as EGR valve doesn't go completely, it won't store an error code. And there's a TSB by Chrysler about it. Pretty simple and relatively cheap item to fix.I went back to my stealer and told them, after all I paid for, they either replace the valve at their expense or refund me all the wasted money which didn't fix the problem. So if you got the same problem, it's most likely not an electric issue, it's almost guaranteed your EGR valve.

But: if the car shuts-off completely ( that includes dashboard, radio etc. Then it's going to be your ignition switch relay. Also a known defect hidden by Chrysler in a TSB.

In regards to sunroof: again Chrysler doesn't admit their mistake, but the 300 is known for failing sunroof and rear windows. Again: this is not an electrical issue or a faulty switch. It's a software glitch which has not been addressed by Chrysler and hard to fix

I have a 2006 300c with 190,000 miles. Was having all of the issues stated above. Mine stall, jerk and cut off while driving. Read lots of comments and ended up doing 3 things.

1. Replaced (1) vt solenoid and had the other 3 cleaned.
2. Changed the spark plugs back to OEM Champion.
3. Cleaned throttle body.

So far so good. If I have anymore issues, I'll come back here if not it means all is well.

Engine shuts down sometimes when waiting for a light or won't start after driving for awhile. Had a previous problem with sun roof which leaked and mechanic thinks it could be an electrical problem caused by water that's causing engine to shut down but I had the problem before with engine running hot. Could the engine shut down because it's running too hot? Changed the thermostat but no help. What can I do about this? Is this a problem endemic to this model?

Car began stalling after WOTs when going to stop, once it did in nuetral when revving fast.
Now the car stalls once I shift it to D/R it idles fine in P/N.
Rpm struggles when in gear for a second or 2 & dies.
I can rev it up in d/r & keep it running but as soon as I left the throttle it dies
- Checked fuel pressure its fine at 58 psi
- Checked the TCC solenoid by jacking on the car up & still dies.

What can I do to fix this?

No vacuum leak, now I cant shift to gear without it stalling, about the IAC if it has a problem would my idle be really stable while on P/N?

I did lower the idle it worked fine but with a little struggle did a log to check the base spark is around (18 in P/N - 14 in D/R) now the car runs but when switchinh to R/D it struggle a little.

Vehicle stalls at idle, on highway all speeds, stop lights. Will restart most times.
Both fuel pumps replaced, gas tank replaced by Chrysler, new battery, new computer, all grounds checked, all fuses replaced. Check engine light comes on once in a while but not regular. (Lost communication code). I have had it to several mechanics and no fix yet. Motor was replaced at 175,000 miles by Chrysler.

I took a drive, switched gears many times, Idle struggles some times from D to R & vice versa but returns to be stable. Gonna clean them up & test the car after WOT.

So would a high rpm cause a car to stall in gear?

Same problem happend again after WOT when comming to stop. Now my car stalls the same !

It will stall/cut out at all speeds. Sometimes it will run twenty to thirty miles and have no issue. Other times it will stall out idle long in the driveway. It does this randomly.

It does not give codes all the time, it cuts out or stalls. Very rarely it gives codes. Two codes were lost communication. Lost communication to transmission.

Its tuned by a diablo predator I can adjust the idle & I did, it worked good but once I went wot it stalled back again, yes I have a CAI on the car its new with 2500 km on it & didn't oil it.
