Have we reached Peak Reliability for internal combustion engine cars? (camshaft sensor)
Our 10-year-old Infiniti has 80,000 miles on it. It recently went from “running perfectly” to “dead in the middle lane” on the Mass Pike (I-90). The transition occurred in about two seconds. The culprit turned out to be a bad “cam sensor” (Wikipedia article on a similar crankshaft sensor) that feeds the ignition timing system. The old-school distributor wasn’t perfect, but timing problems would result in a rough-running engine rather than an instantly dead engine, no?
Based on my experience with a 1998 Toyota Sienna that simply refused to break, I thought that we were on track for service-free and incident-free vehicles. But now I’m wondering if Peak Reliability wasn’t 10 or more years ago. Cars today have a lot of complexity and, apparently, potential for hard and sudden failures. At 8,000 miles and one year old, this particular Infiniti had an all-systems meltdown caused by some brake system controls. The latest cars have auto-braking, lane-keeping, and various other collision-avoidance systems that would seem to have the potential to disable the vehicle.
Readers; What do you think? Will cars actually be getting less reliable from now on? Except maybe electric cars that have a lot fewer moving parts (but Teslas aren’t good for reliability, are they?).
[Separately, I’m wondering why this Infiniti could be shut down by the failure of a single sensor. The camshaft is plenty long. Amazon sells camshaft sensors for as little as $13 as replacement parts ($172 at the dealer, plus $388 for installation). From this I infer that the factory cost of a sensor must be less than $1. Why wouldn’t Infiniti put in 2 or 3 of these and have the ignition computer pick the cleanest signal?]
Finally, if you’re in the market for a new car, don’t neglect politics. A wealthy Hillary-supporter on Facebook regarding the replacement of a beloved Volvo: “Trump anxiety is a factor in any spending even though the market has been kind to me.” (i.e., Trump has made him $1 million richer, but he is so anxious about the future that he is keeping his money in the market rather than cashing out $50,000 of gains to buy a fancy new car).
