Yeah, they don't like the "I'm going to sue this rich famous person to chisel some money out of them" card either.
If you're right, then that means that Andre is an extortionist scumbag. Why would you believe that? He's always been a great guy, and has never done anything remotely negative or objectionable.
Okay. Let's say this is the case. We'll take that as a truth - guy told Andre that the redo would screw up the airbags. Why would Andre then demand a full refund? I mean, the implication is that Andre is such a scumbag that he would extort the guy for the full cost of the job (figure 5 grand or more) for a few hundred bucks in Mercedes mechanic time. You're pretty much saying that you believe that the likeliest story is that Andre is a scumbag.
Maybe the guy did not tell Andre. Maybe it was the 2015 model and he didn't realize that unplugging the modules would force a reset. Mabye his associated neglected to tell Andre. If any of those things are true, maybe Andre went to pick up his car and the air bag light was on and he came in and said, "WTF is that? And the guy said, "Oh yeah Andre, no biggie, just drive across town in your less-safe vehicle and get that fixed at the dealership," to which Andre responded, "no, and I'm not paying you because you didn't reveal this to me." Maybe Andre was not told and the light came on when he was driving home and scared the hell out of him, he called, and the guy said, "oh yeah . . . about that . . . "
But all we have from Andre right now is a tweet or two. I find it fascinating and frightening that you, presumably a lawyer, have already settled on the likeliest scenario being Andre is a and an extortionist w/out even hearing his response to the complaint.
My experience has been this - 100% of plaintiff clients will lie to you when they tell you what happened. You'll never get the whole truth. 100% of filed complaints have distortions, half truths, and outright lies in them.
I have faith in Andre, who always struck me as a good human being, and a happy go lucky guy. I'm going to wait to hear his response before I conclude what's most likely, but as a starting point, based on what I know about Andre, it seems more likely than not to me that the customizer is the sleazebag, Andre called him out on it, it hurt his business, and he found a scum attention whore attorney to file a suit. You know already the attorney is scum because he said that Drummond said that his client "almost killed him." That is a scum lawyer distortion - Drummond tweeted that they did things that "could have cost" his life. Only a scum lawyer would publicly utter such a despicable distortion.
