The Maintenance Free Myth

Sometimes we hear people in Winnetka say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's vehicles are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most Winnetka drivers don't realize how high tech automotive fluids have become,  fluids such as engine oil, transmission fluid, coolant and brake fluid.

Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and distances march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories we've heard to emphasize and show how important it is to get things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and money. But they are tales of a stitch in time saves nine.

The first comes from someone who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated on a highway in CA and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been completely replaced - just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundreds of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.

Another story involves the true cost of skipping an annual inspection. This guy took his SUV in for the CA safety inspection to renew his registration. At the Winnetka inspection station, he learned that the law had changed and that his newer rig only required an inspection every two years. He was very happy to save the money. The problem was, his rear brake pads were very worn. Two months later, it was bad enough that he could hear the grind - over the radio, DVD player and the kids. He took it in to get the bad news. Both of the rear brake rotors were damaged. The left one could be resurfaced. The right had to be replaced. So saving a little on his safety inspection turned into an extra $500 over what brake pad replacement would have been. Moral of the story for Winnetka drivers: don't skip your annual inspections. The irony is that many Winnetka service centers would have done a brake inspection for free.

Next: a teenage daughter and a curb. Daddy's little princess smacked a curb when she turned into a shopping center and popped the tire. The problem came when Dad didn't get an alignment. The impact was hard enough to ruin the tire - so it was enough wreck the alignment. But instead of an alignment after the first tire, Papa ended up buying a second tire a few months later - and then an alignment.

Situation: son and wife with cars from the same vehicle manufacturer with essentially the same engine. Our staffer checked the son's maintenance schedule and saw that it needed a timing belt replacement at 90,000 miles/145,000 km. He had it done - it cost several hundred dollars. His wife's car had about 60,000 miles/97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 60,000 mi/97,000 km. At 63,000 mi./101,000 km, the belt snapped on the interstate. The valves all crashed down into the cylinders at high speed, the entire head was shredded and it had to be replaced. The cost: several thousand dollars. Does he wish he had checked the vehicle manufacturer’s maintenance schedule? You bet he does - every time he passes a big-screen TV.
