Sounds like a tire issue.
same problem, and same year. started immediately with new tires. have had them rebalanced 3 times. had them replaced with a different set entirely. it feels like old biased ply tires, when they flat spot. its much worse in the mornings, and when the tires are cold. not nearly as bad in the afternoon. tire guys are as confused as I am. I personally did tires for a few years, and have a good idea what it takes to make these things run smooth. this one has us all baffled.Mine does the same thing right around 65-70. It just flutters. I got brand new tires and all new front suspension. I guess I should look into the brakes.

What tires are you running? I've heard of KO2s having issues like this very frequently.

stock size and tread tires. I couldn't feel ANY difference between the first set, and the current ones. its annoying as hell though...
They are Michelin LTX ms/2.
hmmm wondering if the weight just keeps coming off?
I threw mine on the lift and ran it in gear. the wheels are rock solid. not a bit of runout. but the tires have a definite bounce to them. the tire shop is going to order me yet another set of tires. this time a completely different brand.You know mine is worse in the mornings also! That’s so strange. I have new shocks and front cv axels so can’t think of what it could be.

I am having the same problem, same tires as you installed by Toyota about 5 weeks ago.. Had them re-balanced, but feeling the steering wheel shake again around 65-70 mph.

It might very well be the calipers seize. I too recently had a small highway steering wheel vibration. I lived with it for a while and because the pads were going, I went to replace the rotors and pads. Found one of the caliper pistons on the inboard pass side was completely seized and the same inboard piston on the driver's side was starting to seize. Replaced the calipers and viola! Rides smooth as glass now.
Thank you NAPA Lifetime warranty!
Good luck!
Well after 4 times of rebalancing at Toyota they confirmed with a meter that there are hard spots on the rotors and the calipers are tapping them at highway speeds. So crazy because I just had the calipers, pads and rotors replaced 2 months ago.
They say “Hard spots”. My steering wheel intermittently shakes when hitting the brakes and also inconsistently while cruising at highway speeds (60-70) they said the balancing was spot on and there’s no play in any suspension or steering components. They recommended resurfacing the rotors but I’m going to take it back to the shop that I had The brake job done and have them confirm.
Thanks, I have a similar issue as well, but I pretty sure it's brake related as my brakes are due for replacement.
If they said "hard" spots and that "turning/resurfacing/machining" the rotors was what needed to be done, I'm sure they mean't to say "high" spots because it just doesn't make sense that "hard" spots would cause it to shimmy, especially when not using the brakes.
Please update your issue after getting the rotors resurfaced!

I have the same issue myself and I have a theory I'd like you to think about: I think that in many cases the tires are balanced within spec but drive-line components are slightly out of balance. I have noticed wheel shake on the highway while going straight, but sometimes no shaking for long straight distances, then while going thru a long bend the shake goes away at some point in the turn, then I go thru another turn and the shake starts to increasingly materialize again. I believe the issue could be that the drive-line rotates at different rates in the turns and in time the drive line components line up in opposing high and low spots -no shake- than while going thru a turn the drive line components eventually meets up to a high + high, -right side vs. left drive shafts perhaps- thus exasperating drive line imbalances and the wheel shakes again at different intensities depending on where you are in terms of where the left side drive line is in relationship to the right side of the drive line. I may be crazy but the more I think about this and experiment the more I think it's got some possible relevance.
