Hello, so took my 2011 Impala LTZ in today because one of the tires went flat last night...had AAA put the spare on last night. Today was told the tire couldn't be saved since I apparently drove too far on it...keep in mind replaced in February and only put 1,300 miles on them but OK, I accepted it...but then they came in and said (2) lug nuts and a stud were damaged...$80. Two months ago everything was fine. Last night, the swap to the spare went fine. So...did they maybe damage something and charge me for it? What is the cost you've seen for replacements? Is $80 fair? The AAA agent says maybe $20...I get businesses have to make money but also don't want to be taken advantage of. Thoughts? Suggestions? Thank you in advance.
