Wacko....
Lonely feeling, getting a raw deal as you did. They were going to have to put the tires back on anyway. Then they blamed the extra charge on the "computer."
I was one of the lucky owners with my 2001 Toyota Tacoma.
In for an oil change and they called, said my frame was rusty and I qualified for a new frame. FREE!
1995.5-2004 Tacomas had a rust problem. The American company that stamped out the frames didn't do a proper rust-proofing, Toyota didn't catch it so if the frame has any perforation, they replace the frames (2001-2004) or buy-back (1995.5-2000) the truck @1.5 KBB, excellent condition. You can be hauling wood, it's still considered excellent condition for the buy-back.
Replaced the frame, rear springs, lower control arms, brake lines w/e-brake cable, hardware, recharge A/C, new anti-freeze, hardware and labor. All free!
My drive train was good, they lifted off the cab and box. Just slid the new frame under and rebuilt the frame.
Here is the common sense kicker that Midas should have done.
Because the old shocks were going to be placed back on the new frame, if I wanted new shocks, just buy them (any brand) and it would be free labor. The work operation was easier for the mechanic. Same job, old or new shocks. It was easier for him because he didn't have to take the old shocks off.
Same deal with exhaust. Same work operation labor wise.
They treated me right! Already had a new Toyota exhaust but I did buy new Toyota shocks. Toyota has a deal. Buy Toyota replacement shocks and/or exhaust, after that it becomes life-time free parts and labor if needed again.
The tires were already off at Midas. What difference would it have been to roll them to another wheel?
They took advantage of the moment and lost a customer. Maybe more customers than just yourself.
Toyota treated me well. I didn't even know of the replacement program. It isn't a recall thing. It is handled differently.
They called me and said I qualified!
The bill sent to Toyota was between $11,000-$12,000.
Only thing I paid for was some new shocks and they discounted that price.
Oh by the way, when they put the tires back on the truck, they rotated them!
Customers remember when treated fairly and never forget when taken advantage of!
