I have a 2010 S purchased used CPO a few months ago. I noticed that in higher speed turns, if I hit a road inconsistency, e.g. bridge expansion joint, depression, bump etc., the car "wags" side to side. I don't really have a good explanation of the effect, but it's like the car is swaying a bit. I have taken the same turns in other cars like a 318 and 328 BMWs and Ford F150 and none of those (not even the truck) show anything like this effect. It's a very surprising feeling given what I expect a Porsche to handle like.

I haven't been able to find any discussion about the effect, but did see two different one-line comments in two different reviews that noted oddness in turns, but they did not go into detail.

Does anyone have any information on anything like this? I'd like to have some more information if this is a known issue or just a Panamera characteristic before I try to explain it to my dealership, if possible.

Cheers

 

would need to know if you have PDCC, what setting car was on, what tires and what pressure

if this car is handling worse than an F-150 ya got a real problem!!

 

Non-PDCC, any setting, Pilot Sports, dealer-set pressure (39-42 depending on temp).

Tell me about it

 

Well in all honesty ya got a 4000 pound vehicle with no PDCC or torque vectoring
Not on a sport plus setting, tires with not the stiffest or lowest profile and somewhat low pressures
May have contributed somewhat to your unstable feeling that is assuming the driving maneuver was being carried out with the proper line through the corner and appropriate steering and throttle input

Also hitting differing surfaces will unsettle the cars suspension especially at higher speeds

 

I'm not sure if you just don't notice it in the other cars, or your not going fast enough... But this is perfectly normal and all according to the laws of physics..... I haven't felt it happen on my panamera yet, but I haven't had it for long either.

My corvette and lexus do the same thing when going fast around turns. A bump in the road will always make you slightly lose traction for a split second, so momentum takes you towards the outside of the turn. Which is the wagging your talking about. If your not going fast enough, then there isn't enough momentum for you car to move enough for you to feel it. The faster you go around the turn, regardless of vehicle, the more you will feel this. Be careful though, it can make your car lose control.

 

Sounds like a bad shock. Play with the tire pressure (lower it) to see if that makes any difference. If the lower pressure reduces the symptom, it may be a shock problem.

 

Fixed the ride by lowering the pressure.

 

Last time I had a similar problem on a ford - it was a shock/or shocks. There was no quick damping so it it wagged.
