Q: My Kia is one of the models that is susceptible to theft. The first fix offered was a software program, but apparently that fizzled. I recently got a mailer from Kia telling me there is now an offer to fix by installing an "ignition cylinder protector." Have you heard of this? Any opinion? Thought I'd ask before jumping in.

A: Go ahead, jump in. Kia said in a statement that it was issuing a security measure in response to social media showing crininals how to steal certain vehicles. This hardware modification — an ignition cylinder lock protector — is designed for those vehicles not eligible for the security software upgrade that Kia introduced earlier. It reinforces the ignition cylinder body and helps prevent its removal. The modified cylinder lock was rolled out in December. Each vehicle gets window decals informing would-be thieves that the car is equipped with enhanced theft protection.

Rotation notation

Q: How often do you, as opposed to the owner's manual, suggest rotating tires on a smaller, four-wheel-drive truck? FYI, I always mark my tires before a rotation. I have caught a major dealership not rotating my tires three times. The first time I was compensated with a $10 gift card, and the second time with a tank of gas. This last time, I received a free, five-year extended warranty and an additional $3,000 on my trade.

A: It sounds like you hit the jackpot. I suggest tire rotations every second oil change because that is easier to remember than the mileage in the owner's manual. You are not the first person to mention marking the tires before service, nor the first person to discover the job wasn't done.

No hurry

Q: As an old fogey, I don't understand drivers who accelerate toward a red light only to have to come to a full stop behind the waiting traffic. Your thoughts?

A: I learned to coast when approaching a red traffic signal. With luck, the light will change to green before I have to come to a stop. For those who are annoyed by start/stop technology, this may lessen their annoyance. As a motorcycle rider, I can occasionally avoid putting my foot down, even momentarily, before proceeding. Besides, speeding to the light doesn't save a lick of time.

Clean, don't scratch

Q: I'd like to throw in my two cents in response to a recent letter recommending using a Mr. Clean Magic Eraser on a windshield. They are mildly abrasive, which is part of the way they clean. Using one once or twice on the windshield should not have a serious impact, but regular use could etch the inside surface, hurting visibility.

A: You make some good points. Although automotive glass is pretty durable, it can get scratched or pitted over time.
