So I've been noticing that the car has been having a very rough idle.

1. Less than 500rpm at idle
2. Steering wheel shakes while idle
3. Car sounds like a diesel (see video below)
4. Sluggish from stop to roll


The car had an oil change not that long ago, I checked the air filter, it's clean, oil level is good. I don't know whats going on...

 

how many miles ?
which year ?
what kind of maintenance was done on this car ?

 

sounds like mine.

 

so no one knows whats wrong?

 

+1 how many miles on the car? is the car throwing any fault codes? OBDII?

 

HAvig the same problem too - here the shop - did a full software yesterday - did not fix issue....stay tuned.

 

Your video clip sounds like my car. I hear a ticking as well. Inside the car, I can hear a faint "sewing machine" kind of sound when I'm driving at low speeds (under 10mph).

I've had issues with rough idling too. For some reason, it seems to be even worse when I don't use Shell gas. I've been meaning to clean the MAF to see if it helps, but haven't gotten around to it. Using a bottle of Chevron Techron treatment smooths things out a bit.

Under warranty, I had brought the sluggishness to the SA's attention many times, but often the tech finds nothing wrong or I'm told that it's normal. They did raise the idle a bit and change the battery in an attempt to resolve.

 

You still haven't posted your mileage. If it's high, it just may be time for new plugs...
Your video sounds like the way my car runs. My car idles at ~500 RPM with the A/C off with just a hint of roughness, which I think is perfectly normal. With the A/C on it idles at ~750 RPM and smooths out quite a bit.

 

Car is at 58k miles. Maybe it's time for a tune-up.

 

Yeah, I think your car is fine, personally...I mean judging by the video and what you've mentioned in this thread. I kinda thought something was wrong when i bought my car with 33K miles...it ran exactly like it does now, just a hint of roughness at idle, especially with the A/C off. It still pulls like a freight train and I can't expect it to idle like a Lexus...I think that's just the way these cars are. The sluggishness from a stop to a roll is a common complaint...the crappy throttle response from the drive by wire. The plugs are supposed to be good for 100K, but i plan on changing them at 80K.
Now, if your car is vibrating really badly, like you can actually SEE the steering wheel vibrate or it's stuttering or stalling, then you have a problem....
