Wonder if someone decided to put red thread lock on it? If one was cross threaded I doubt all would be cross threaded.
Torque sticks are unreliable - You tube video showed big difference between brands and a big difference between an air and battery impact wrench using the same stick.
I remove lugs with impact - but always hand start the nut and use the impact at lowest setting (first bump stop) then use a torque wrench for final tightening
really would like to know the entire story and it's conclusion
Nobody puts thread lock on wheel install so why would you think it's an accident? Or are you thinking someone is screwing with him?
Glad that works for you. Not sure how you can watch a torque value. I fortunately do not know "my techs" as I am able to maintain my own rides. Every journey into a auto shop is an unknown to me and I strive to avoid them. I recently had a Chevy dealer in PHX telling me I had a blown head gasket on a '14 with 45000 easy miles. I took it out of their hands. It was a 15 minute, $110 fix because the plastic coolant tank had popped at a seam. Easy find with a cooling system pressure check. I don't trust nobody but me anymore...... sad state quite frankly.
EDIT: They had the car for 6 days.....put a 100 miles on it while they were "diagnosing"...... M#^$(&F&^!@#$s

I agree nobody would think that - but you never know who is working on your car especially a tire shop. No one would change the oil and leave the drain plug out - but unfortunately have actually seen this happen
Here is a possible scenario. Manager tells new kid put the lugs on tight so they won't come off. Kid thinks for a second I'll also put some lock tite on so they won't come off

That is "I forgot to put it on.". I'll bet that every seasoned tech has done it a time or two. Have I made some bone head moves? Sure. We all have.
That is kinda a stretch, I hope. If not, the owner is looking at 4 wheels being locked up.
Noobe with a big impact wrench and no torque sticks or torque wrench.
DT uses a impact wrench with the regulator turned down with torque sticks for the first 50 - 70 lbs and then finishes up with a torque wrench to the proper torque in a star pattern.
I had the same experience with my new 06 GT Mustang. using a proper lug nut socket and 4 foot cheater bar and all my 180 lb weight to break them loose, all of them. Made the dealership give me new lug nuts.
Talk about mum-nuts.
Wouldn't be nearly as concerned about the nuts, it's the studs that were most stressed. (stretched)

Update: Long story short, his last shop visit did no tire / wheel work, at this visit, took the cranked nuts off, put on new, didn't seem to be any damage.
Beforehand, had a new engine replacwement under warranty at a local Chev dealer, basically dropped the whole bottom of the car, that's where the overtightening came from, Dealer didn't offer anything but says keep an eye on it.....................typical response.

How did they over tighten it so badly and how did they take it off?

Sorry, didn't get names, the how is self explanatory, the owner didn't volunteer giving the who, I suppose pointing the finger would not accomplish anything at this time. The other shop used a high torque impact for HD truck wheels.

On a road trip with friends, the other car developed a semi-slow leak in one tire and he pulled into the nearest interstate tire shop for trucks. Removed wheel and checked, then when shop was about to reinstall I asked what kind of torque they used. Something like 250 lb-ft.
"Step away from the impact wrench and nobody gets hurt." A close call.

You do have to be on top of the folks that work on your car, sometimes that can be hard to do.
New parts should be on order; perhaps even managed to warp the rotors depending on how the over-tightening was done.
Exactly. My mechanic uses the term "spreading the metal" when that happens. When I had brake work done on my C6 years ago, when I got the car back it was shaking like crazy. My trusted mechanic said your lugs are way over tightened causing either your aluminum rims or rotor hats to distort. He said watch after I re torque them. Sure as **** the car was smooth as silk again. I was a firm believer in over torqued lug nuts after this.

I normally specify the torque. I don't do quizzes. Specifications are about 60 ft/lbs and I do final settings since I have antiseize on the threads.
