My 2017 cx 5 engine will sometime vibrate waiting at a red light maybe after 30 min of driving around .
Technician says its a common thing with Mazda and absolutely nothing to worry about .
Just wondering if others think so?
The SkyActiv 2.5L is a noisy, vibrating engine from the get go.
Just have a look and listen when the bonnet is open.
Nothing new there.
That said during driving, vibrations should not be noticeable except on cold start up.
At a stoplight, try pushing your foot down a bit harder on the brake pedal. This should cause the transmission to slip into N and reduce vibrations through the wheel.
Yep. The torque converter disengages to reduce drag at a stop. When you release the brake, you can feel a little nudge as it re-engages. I believe all SkyActiv automatic transmissions function this way.
Whatever gave you that idea?
Can you explain what would cause this behavior in my CX-5 if it's not the torque converter re-engaging after taking my foot from the brake?
1. Foot off brake
2. 1/2 sec later, vehicle slowly starts moving forward
3. Steadily idles forward
More posts here suggesting the TC disengages at a stop.
I noticed my CX-5 roll back two or three inches taking off from a steep incline before "catching", which I suppose would make sense if the torque converter is disengaging at a stop.
It could be but finally got my answer.Isn’t this the third thread you’ve mentioned this vibration thing?
Exactly! Someone also said on the other day that our SkyActiv-Drive transmission will shift gear into "Natural" by itself when the vehicle is stopped with foot on brake. He also said it's described in the service manual. But I couldn't find anything in "service manual" describing this, nor a copy of such description posted from any Mazda official documents!Now, we agree that the TC "disengages" or "slips"; that's just terminology. But you said the tranny goes into N, and that just can't be.
Glad you noticed the problem early and your dealer was able to locate the cause of the problem and fixed it.It could be but finally got my answer.
Brought it in for an oil change ,the dealer had to change a support for the transmission.
So no more engine vibration at red lights.
