Hi all - does anyone experience a shudder when driving the car for the first time after it's been sitting overnight or sitting all day? It feels like driving over mini sped bumps or driving with the brakes/parking brake on. It only happens for the first two mins or so then disappears. The car is a v6 tech AWD, has just over 800 miles and a build date of 08/15. I don't have the 1-2, 2-3 hard shifting but I do have the coasting/surging when slowing down and the trans is going into 4th gear.

 

I got that yesterday. I parked the car for week and when I started driving I got a constant vibrations and shudder. But after about 5 min it disappears. I have a AWD advanced with Michelin pilot sport AS3 over 19 inch wheels. I thouht it has to do with the tires and cold weather. Cold weather might make all season tires hard and weight of the car makes the contact point of the tire flat. Cold weather keeps it in that shape for few mins. Thats my explanation.

 

Thanks - that could be it as the weather has been getting colder here (CT). Car is garaged but still could be it. I'll keep everyone posted if I notice something different.

 

I have had the exact same issue. When I drive from my house to the highway I don't notice it because I have a couple mile drive and it seems as though whatever causes it has a chance to warm up. However on my ride home from work I hop right onto the highway and I notice an extreme vibration and shudder. Very odd and I don't have the slightest idea what it could be
