I had this issue of when pressing the brakes when going over 45, the front end shakes & makes a pulsating noise like the rotors are warped, since buying the car. I've taken it in 4 times for it to get fixed. 1st 2 times they said couldn't replicate issue & rotors are fine(they did have to replace both calipers because they found they were leaking.) The issue persisted with new calipers & the faster I go the more pronounced it gets, this time I had the service manager ride along, he said it was tire noise and there was nothing else they could do. I then went on vacation & rented a Sonic. It had the same tires & wheels but did not have the issue. I also went to a Chevy dealer & test drove a Sonic (the same LT trim level as mine) and it did not do what my car does. Took car back to dealer when I got back & got the tech to ride along he also said it was tire & road noise and the cars I drove were in a different state so I couldn't really com[pare it because the road & conditions are different. I said BS & called GM CS & they called the dealer & had them do something that lessened the issue but it was still there just not as bad. They gave me an extend service plan & warranty & said bring it back if anything else happens. Driving the car on the highway tonight I overtook a car, got up to about 70 & the front end started mildly shaking I press the brake & this happened...

I replicated it for the video & got the car towed home because I didn't want to drive it for another 60 miles with that happened on the highway.

They said it's not the ABS system previously and no it's not a low tire(I know the light is on, but its because I bought 17" LTZ rims to replace my 15" wheels & did not put TPMS in) can't take it to another dealer because they are the only Chevy dealer on the island...(one of the bad things about living in paradise, Kailua-Kona, Hawaii....)

It's the same thing that was happening previously( the car never shook when going 70 either), now times 10. You can hear it, feel it in the steering wheel, brake pedal & seat. It was so bad that the car & stuff inside started vibrating. Going to call GM again on Monday, I just don't feel safe in the car with my 6 year old & I don't think they are going to fix it on the 5th try because they don't know whats wrong. I feel like I'm the guinea pig & they'll figure it out after the brakes fail & I crash.

I also have the grinding into reverse issue(3rd time) & rear wiper fluid sprayer(2nd time) doesn't work they have to fix this time in.

This is will be the 6th time the car will have to go in 20 months since purchased. Total issues with this car 11, total days out of service for issues 46.

Drive shafts maybe or lug nuts on wheel are not torqued down to the correct specs.

It's childish for them to say your test drive of another Sonic did not have this problem because of road differences. All they have to do to prove that to your satisfaction is to put you into one of their own Sonics, again with a tech, and drive the same route the same way. That eliminates road differences.

If they say it's tire differences, then they pull the tires off your car and put them on their Sonic and again go the same route, same driving style.

Either they are correct or you are, but they have the power to prove it, and either get you off their backs, or discover that you were right after all, and get in there to figure out what the issue actually is.

The lug nut issue is probably a red herring, because they have pulled the tires on and off while working on your brake caliper issues. Odds of getting this wrong multiple times in a row are low. But if they do the tire swap I suggest, and then your problem mysteriously vanishes... well I guess you should buy a lottery ticket.
