Hey all,
I finally got the CLA. I've been happy but there is definitive vibration when the car downshifts from 3 to 2 to 1 when coming to a stop. Nobody knows if this is normal or not. Mercedes says it's normal. Also when braking at around 30 mph there is another type of vibration. Also, when in "sport" mode the handling is really jerky. Any thoughts?

 

[BenzFan]

Thats weird. Is their a vibration at idle when stopped?
I'm thinking it could be the engine mounts

 

[shenandoah1]

No there is not a vibration on idle it's only when coming to a slow stop. Others have said because it's a manual-automatic you will feel the downshifting. But who knows?!

 

[AMG4Matic]

where is the vibration coming through? steering wheel? or the car?

 

[sleepyhead]

Does this occur during downshift or braking? If braking it's probably an issue with the disc or pad, especially if during the entire period. When you say the vibration is during the downshift, do you mean right when the gears change or during the entirety of slowing down? And as the above asked, is it something you feel in the steering wheel or in the car as a whole?

 

[shenandoah1]

The vibration is from the car as it is downshifting from 3 to 2 to 1 to when I stop. It seems to be during the gear change.I called Mercedes and the rep said, again, because it's a manual in automatic I would feel the vibration. Still unsure. My Mitsubishi Eclipse I had never felt like this. I'm surprised that a Mercedes does not feel smooth. Also what's with the jerky feeling in "Sport" mode? Thanks

 

[booker]

vibration as in the same vibration one feels when learning to downshift blip and miss, that rattle your teeth rocking back and forth...

If thats normal... well i don't know what to say about that...

Thats a very nissan answer you got.

 

[AMG4Matic]

hard to say without being inside your car.

is the vibration throughout the entire downshift rev drop? vibration as in buzzing through the car? or jerking?

 

[sleepyhead]

Ditto. If it really is the downshift it's kind of hard to tell without being in person. It could be normal (again, this is one of those things that you can spend 1000 words describing and it would take all of one second in person to see). If Mercedes says it is normal why not test drive other cars with paddle shifters and see if it is there? At least then you have more to argue with them about.

 

[holding]

like sleepyhead said, if MB is so adamant this standard operating procedures see if you can get your hands on one of their CLA demos and replicate the situation. If it doesnt replicate you win, if it does they win....

 

[shenandoah1]

It's not with the paddle shifters. It's in "E" mode that I feel that little shutter. I will see If I can do a test drive. Thanks

 

[shenandoah1]

Took the car in and they say it is the brakes. Under warranty so they are going to replace the discs as they say they were warped. We'll see if the that flutter still occurs when coming to a stop.

 

[StayCLAssy]

Brakes was my first guess but since you said in e mode it through me off.

 

[shenandoah1]

Well, I got the brake discs and pads replaced. I no longer have pulsating when braking but I still have that fluttering when coming to a stop. The tech took it for a test drive and it happened 80% of the time. He believes it is normal for this transmission but because the car is so new he has no other comparison. There was no other car on the lot to test drive. If it was "normal", why doesn't it happen 100% of the time? Any thoughts? Does anyone else have this issue on the CLA?

Mine has been perfect so far. I'm not sure what you mean by fluttering, though.

 

[shenandoah1]

When I come to a stop and the gears downshift from 3 to 2 to 1 whether it's in E or S mode, I feel a flutter sensation from the car. It's not a noise but a fluttering vibration. And it does not happen all the time.

 

[sleepyhead]

From the steering column or chassis?

 

[shenandoah1]

from the engine or transmission. I can't tell. But it's not the steering wheel.

 

[ZILLA]

Mine downshifts sloppy in ECO mode, like it slams into gear

If the vibration in the brake pedal? If so could be warped rotors
