It does not mean we will evade a warranty rework of something we did. If there is even a grey area that something needs to be covered under our warranty we will cheerfully take care of it even if it might fall into a grey area.
What the title of this post means is we do not want a warranty situation to occur in the first place, most of all when we should have known better. That means we do a job twice and only get paid once, the vehicle owner is inconvenienced and there could even be tow service expense incurred. For these reasons, we install only the most reliable parts available. We just say no to cheap starters, alternators, etc. with a known poor track record regardless of the fact that they might cost considerably less than parts with a good track record.
Our #1 wholesale parts supplier will look up the parts return % of any part # on request. I check this frequently. When the part # is priced to low to be true, but the statistics on it are not so good, that part # is not an option for us or an option of last resort if there is simply nothing else available. (Rare circumstance.)
Thank you for reading this and your understanding, Don
