What is some of your Pet Peeve's

[mrmikey]

A recent peeve of mine is traction control on my Mazda.

My '19 Ram is the same way. My driveway although steep is short. If I forget to disable the traction control trying to get up it when snow covered in 2WD is impossible. I could do it in 4WD but it's a sharp right turn at the top and I don't like having the transfer case and axles locked while turning on dry pavement.

They all seem to be like that. I took a curve a bit too fast on an unplowed road yesterday and found myself heading out through the rhubarb. When I stepped on the gas to pull it out, the engine went"bleah". It always reminds me of the good old days when you set the timing too far advanced...

Today's pet peeve is people who hit the brakes when they get on a short stretch of ice. The road is dead straight and level - ease off the gas and hold the wheel straight until you're past it. There's no reason to explore the corn field. What are the odds of having a cop right between the moron and you to get a front row seat? Fortunately there was nobody coming the other way when he spun across the oncoming lane.

It's like the computer is yelling at me, "hey dummy, stop applying throttle!" And in return, I'm yelling, "hey you stupid car, we're not up the hill yet!"

LED's operating off 12VDC likely just have a single series resistor, and maybe a capacitor for reducing any flicker. The LED's themself should basically never fail (> 100 years MTTF), and unlike an LED bulb designed to operate off houshold 115VAC, there's no "power supply circuit" to fail on a DC system.

If they happen to use electrolytic capacitors for flicker reduction, that would be the component that fails first (~20,000 hours), but I honestly wouldn't expect them to use those today. There are just too many cheaper and more reliable ceramic alternatives today.

That leaves the resistors, which if well-chosen, should last many decades. But if there's a voltage regulator mishap, that could wipe 'em all out in one big flash.

I blew nearly every bulb both inside and outside my 1984 Mustang about 30 years ago, by bypassing the voltage regulator, while trying to debug a bad wiring harness. It was very exciting and very bright in my garage for about 3 seconds. Live and learn!

Depending on the application, LEDs can be and often are driven too hard, which causes them to fail. A prime example is household LED bulbs. Driving fewer LEDs harder to get more light out of them is cheaper than adding more LEDs. Also, many LED bulbs have very inefficient power supplies that run really hot, probably consuming more power that the LEDs consume. Bigclive.com has done several videos on how to modify LED bulbs to make them last longer.
I doubt that is the problem with automotive LED applications, where LED failures are probably more likely attributed to bad circuit board design, failed solder joints or moisture intrusion.
An example is the cluster PCB in my '06 F150 that has a common problem of the brake malfunction light coming on when there is no problem. The most common cause is a cold solder joint on one of the connector headers, or a cold joint on a resistor in the circuit. One of these days, I'm going to get brave, pull the cluster and attempt to repair it. There are several videos that show the process, and it doesn't look all that hard.

Store credit.
What a peeve THAT is. Right now there are a few businesses that owe me money via "store credit" which means I have to remember and keep up with it. I paid them in cash, then because I returned something defective I get credit. It may be a year before ordering again.
Just a pita peeve!

Most home LED fixture failures I have had across brands is usually the capacitor.
If I didn't have to pretty much break the bulb to open it, I would probably need to buy less replacements.
Every outage or brownout I seem to lose a "bulb"
If they designed it better with a cap that could take some more punishment, they would last and last.
But it's cheaper to use those lower quality components, and they get a second bonus in that you have to buy a new one.
I still have some incandescents that I got with the home 9 years ago that still work fine.
