Have a 04 Acura TSX. Currently on my fourth battery. Being replaced approx. every two years. Number one, replaced as “free replacement” did not actually fail, but was noted to “sound weak” at service visit, “verified” by testing and replaced under warranty. Second battery dead one morning. Since was only two blocks from dealer, wife called, they collected her and car. Put in new batt, old one dead. Charged lots of money (dealer pricing) cause replaced batt was now over four years old(from time original purchase). About 28 months later, told during servicing, batt was now problematical, could fail at any time. Cost of new one would be “pro-rated” but, to me, still expensive since the cost was so high to begin with. Since this represented a third battery going out at approx. two year intervals, I asked the service rep what is going on. He responded, with an absolutely straight face. “It’s not unusual, in fact perfectly normal for batteries to give out at two years or so. Every and multiple checks of the cars’ electrical and charging system showed it to be in excellent working order. In fact, he routinely replaces his, and especially the battery in his wife’s car at two year intervals.”
I went to a major retailer and got a battery. The service guy said that the battery they pulled out was problematical and possibly going to fail soon. No known reason or guess as to why a 28 month old battery was “going.” Did I miss some major change in the way cars now work? Is there some major regression in batteries going on here. The problem is I’ve asked many friends, relatives and others and surprisingly find many who have no problem with and/or believe in the two year rule. The normal commute is 15-20 miles each way. We have no (extremely rare) weather extremes, especially in temperatures here in Hawaii. Is this the new norm, or is the rest of the automotive world nuts?
