Jerky acceleration while turning

[Gratiotguy]

2011 CTS coupe, all wheel drive, 112,000 miles. 3.6 direct injection. When making tight turns at low speeds, like when navigating a parking lot, I've noticed that there is a jerking while accelerating with the front wheels turned sharply. Otherwise it drives fine and runs great.

I've searched a few forums and the closest symptom I can find is a torque converter issue, but I don't experience the jerky acceleration as described by those with bad converters - at higher speeds. I also read that it could be the transfer case fluid, or a bad driveshaft support bushing.

I'd really like to narrow it down, if possible, before bringing it to the dealership.

Thanks.

More likely a problem with the CV axles and/or alignment (toe on turn) than a torque converter. The TC and transmission don't care if you're turning unless it is causing a change in load.

Sure noise is not from the rear?

There really isn't any noise associated with the jerking/stuttering. It can be felt mostly thru the steering wheel.

Talked to a friend with a new AWD Mercedes who experiences the same thing. It's a known condition in the MB world, referred to as 'crabbing'. Sounds like a few things will increase crabbing: wide performance tires, new tires, cold weather, alignment, tire pressure...

I just had new tires installed on the front, the rear tires only have a couple thousand miles on them. All are OEM spec Michelin, correct size and air pressure, and I live in Michigan and we are just finally coming into spring weather.

Anyone else heard of this?

Just updating for reference. I took the car in for a four wheel alignment. The shop gave me the 'before and after' alignment specs. Caster and thrust angle were the only two measurements that were within specifications. After the alignment, the crabbing is almost completely gone.

Thanks for adding the conclusion. It makes sense that tracking could have been involved.
