I just turned 3000 miles on my C. I started the car and the engine chugged and knocked like I have never experienced. I turned off the engine and restarted and no problem. Any body know what gives?
usually, this is the result of starting the engine, and then shutting it down quickly, such as to move the car a short distance.
generally, this happens after starting a cold engine and shutting it down before warm up has concluded.
this is due to ice being cold, started, shut down and next time started, there is unburnt gas in the cylinders.
nah, many people have had this issue. you can find a ton of threads on it. they thought they solved it with an intake manifold redesign. it helped, but they still do it once in a while. just shut it down and fire it back up if it happens again.
Please report this knocking to Toyota. I'm surprised at how many people think it's not an issue just because it might only happen occasionally. I have had it happen to me twice. Today it was warm and I moved the car about half block and parked on a slope. I waited for the ICE to shut down. Upon starting up several hours later, the engine knocked for over 10 seconds. Applying the gas seemed to stop it, but then it returned for a few more seconds. Engine knocking is not good. Something is wrong with the design.
You need to let it run and only turn it off once the ICE shuts down. The ICE has to warm up, it takes about two minutes. Do this and it will not happen again. It's a non-issue, caused by driver error. Remember this is not a normal car and can't be driven like a normal car.
I've experienced this issue at least 3 or 4 times that I can recall, and each time it happened it was always a short distance driven, like moving the car from garage to street or driveway...I try to remember to hit the EV button so the engine won't start up, but I occasionally forget or for w/e reason, the EV mode won't kick in (low traction battery charge level, battery too hot or cold) so the ICE has to fire up. Next time I go to start the car later, it has the shakes for a bit, but it does indeed go away after the car's been driven around for a little while. For me, it really is a non-issue, since it does not happen all that often and most times, is easily avoided.
