Had this happen a week ago and still don’t know how to feel about it.
Basically a few months ago I had my steady mechanic of 2 years install a car alarm system with a kill switch into my car. I worked fine for a month but then would randomly have the alarm go off at all hours and even while I was driving. I told him this and told him to turn it off which he did. Things were fine for about a month but then the car alarm started to start going off despite being disabled and eventually my car refused to start. I got AAA to tow my car to his shop and have him take a look at it and told him that the alarm system’s killswitch much have somehow accidentally switched on permanently and had killed the battery. So then he did a few tests and replaced my battery and told me that the problem was that when he installed it he didn’t check to see if my car battery was low and that causes a bunch of electrical problems that caused the alarm to go haywire which seemed believable enough.
However afterward when I told him I wanted him to again disable the alarm system because I didn’t want to deal with it anymore he got somewhat aggressive and asked me “Do you know how a car battery works?” I said no but then told him I just didn’t want to deal with the car battery getting kill-switched again and again he told me rather aggressively “Do you know how a car battery works?” I then said Yes and then he told me “Yeah how does it work then?” Miffed I just told him I wanted to pay for the battery and that was it so I did.
I understand what he was saying now (the car battery was just a cause not the symptom) but the way he aggressively phrased it made it seem like he was treating me like shit because I was inferring that he needed to do some more free work on my car to fix it (since the install was still under a 6-month warranty from him). I’m now considering just finding another mechanic since this was very rude and just came out of nowhere. Anyone else think I’m overreacting?
