Any warranty work, or warranty work related to the wheels, tires, brakes, or hub? Because either way, that's bull*crap*.
I had a bad vibration between 28MPH-42MPH. First it was stated that it was due to my aftermarket wheels and Sottozero 3 winter tires. Then I put my factory wheels back on and it was supposedly due to the worn tires. Yea, I know, total B.S. So I said I'd buy new summer tires for my factory wheels.
I asked the SC to match Tire Rack's price, which they wouldn't. Fine, I'll pay the inflated price, but I want some kind of Road Hazard warranty (which BTW, Tire Rack includes for *free*). They said if I buy the tires from the SC, there is no kind of warranty available whatsoever, paid or otherwise. Well, I'm not spending $1600 on tires with no Road Hazard. So I asked if I could buy the TO tires from Tire Rack and have the SC install them. They finally very reluctantly agreed. It cost me almost double for them to install as opposed to other tire shops. Well, guess what... the vibration didn't change.
Now, they blamed it on the *new* tires; saying the the RFV on the rears were way off and this was causing it. Yea, I know, total B.S. So, I called Tire Rack, which provided over the top customer service BTW, and they sent me a new pair of tires overnight. I got a call the next day from the SC, which was asking me who was going to pay the $100 to M&B these 2 new tires. Are you kidding me?! Any other shop, would have done it out of good customer service. Well, I replied back that they should have never sent me home with the car, knowing that the RFV was way out of wack, so I expected them to handle it. Their response was that I didn't pay extra for the RoadForce balancing! Again, are you kidding me?! I paid almost twice the cost of any other shop for them to M&B, and they didn't at least RoadForce *check* them?? I pushed back up to management, and they reluctantly agreed to M&B them. Well, guess what... the vibration didn't change.
Now all of a sudden, after swapping tires that were operating perfectly fine, I have a slow leak on one of the rears. I bring it back, assuming they didn't tighten the valve stem core, and for them to still find the horrible vibration, and low and behold they find that my rear wheel is cracked. Hmm, wasn't cracked before... So, they claim that the cracked wheel is now the culprit behind the 28-42MPH vibration. Yea, I know, total B.S. They also stated that they put on a set of their own wheels and the vibration went away. I ask them what they are going to do about this cracked wheel that was not cracked before, and as I'm sure you can guess, absolutely nothing. So, I take the wheel to a reputable rebuilder, and they weld the crack. Oddly, there was absolutely no bend, deformation, or anything: the wheel was perfect other than a small crack on the inside rim where the bead is. Well, guess what... the vibration didn't change.
So, at this point, I took the factory wheels and tires off of my buddy's brand new Model S that he just took delivery of. Guess what... the vibration didn't change! So, what about them stating that they put their own wheels on and it went away?? I brought my car back up to them with my buddy's wheels on, and told them; here you go, new factory wheels and tires, and it still vibrates, so now what? They said, well now you're introducing way too many new variables. So they had me put my wheels back on and then said that they would try it again with their wheels. I implored them to let me go for the ride with them this time when they put their wheels on. They didn't... However, they did come back and say that low and behold it was doing it for them now. So they looked into it further and found a cracked motor mount!! But it doesn't end there...
After they had originally mucked with my car, it came back with a creak every time you came on and off the throttle. They said they couldn't reproduce it and sent me home with it. This troubled me because it was very easy to reproduce and I even had done it for the tech when he was in the car the first time I brought it in. So, this last time, before I left the parking lot, I tried and sure enough it still did it. I immediately went in and asked for the tech and the SA to get in the car with me so they can hear it. After demonstrating it again, they took my car back into the shop and guess what... they found that the axle bolts weren't tightened to spec!
