Alfred Hitchcock once made a mystery thriller film called "Rear Window." It had nothing to do with the rear window of today's cars, SUVs, CUVs and light trucks.  But there is one thing that some drivers DO find mysterious.  Why don't the rear windows in the second row of many of these vehicles go down all the way? You've probably seen or owned one or two. That rear side window only goes down about a third, a half or three-quarters of the way. Yet there are some similar vehicles where the window goes down all the way.  What gives? There was the rumor going around that the restriction on how far those windows could go down was a child safety feature.  The thought was that if those windows couldn't open up fully, a child (or pet) would be less likely to fall out.  But it turns out the real reason is that the way the rear doors were designed, there was just no room for the window to go down all the way into. Many vehicles are configured so that the rear wheel arch ... read more

So your vehicle won't start.  What's the first thing that comes to mind?  Battery dead? Starter motor worn out? Out of gas?  Well, those are all reasons that make sense.  But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it.  Here's how that works. You have lots of computers in your vehicle.  They need to know the status of things so there are several sensors monitoring various things going on.  These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel.  They know when things aren't quite right and prevent you from starting your engine if that's going to damage it.  Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly. Here's an example of a sensor doing its job.  Your engine needs oil to lubric ... read more

  Hello Rockville, let's talk about brakes. But the mechanical aspects of the brakes themselves are just one issue. There's also the power brake pump and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.Let's step back. A new vehicle or truck rolls off a local Rockville showroom floor. It has brand new brakes with brand new brake pads. The brake lines and pump are filled with fresh fluid and are completely clean inside. And the tires are brand new, with full tread. It is ready to go.Naturally, braking power is at its peak performance. Now the miles/kilometers start to add up on the vehicle. Rockville drivers tend to focus on the brake pads. In the automotive business, the pads and shoes on drum brakes are called the friction material. That's because they provide the friction used to stop the vehicle. The pads are designed to be effective throughout their useful life – it's not until they are worn so thin as to be out of 'specs ... read more

A lot of Rockville drivers have asked whether or not they should use their severe service maintenance schedule, which is listed in their vehicle's  owner's  manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for over 30 years and is a speaker, a trainer and a writer. Cricket says there's so much confusion on this topic because, "Most owner's manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service.' Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement and transmission service be done more often: either in fewer miles or in less time." Foreign and domestic vehicle manufacturers create a specific schedule for each vehicle they manufacture ... read more

If someone told you that your vehicle could have the same power but with a smaller engine, wouldn't that sound like great idea? Just think, a smaller engine would save you money at the gas station and you'd still get the same horsepower. The technology to do just that has been around for a long time. It's called a turbocharger. Race cars and other performance vehicles have been using turbochargers for years. It gives them a power boost without the need of a bigger engine, saving them fuel and pit stops. Automakers have offered turbo gasoline and diesel engines for years, but there were problems with durability. Plus drivers had to make some driving adjustments with the way turbos delivered power. Newer turbos, though, have been vastly improved, and manufacturers are including them in more models. For example, Jeep offers its 2019 Cherokee with a choice of two engines that each make about 270 horsepower. One is a 4-cylinder turbocharged engine and the other is a 6-cylinder conventional ... read more

If you've ever gotten in an unfamiliar vehicle, maybe a rental car, you may have pulled up to the gas pump and wondered, "Which side is the fuel filler on?" Here's a tip for you.  There is usually a little arrow on the instrument panel near the fuel gauge that points to the side where the fuel filler is.  But why are the fuel fillers not all on the same side, anyway? There are lots of reasons.  At one time, many manufacturers tried putting them in an easy-to-reach spot: in the center of the vehicle's rear end.  Some even hid them behind a hinged license plate door.  Cool place, but it turned out not to be a good idea.  When a vehicle with a fuel filler in the rear was hit by another vehicle from behind, it was much more prone to catch fire and explode. Safety regulations now dictate that the fuel filler doors be placed within crumple zones and away from where they can drip fuel on hot exhaust pipes or near electrical connections.  But why do manufactu ... read more

If you're like most people and drive a gasoline-powered vehicle, you need to be up to speed on its fuel-related components.  They're pretty basic: the fuel, the fuel filter and the fuel pump. The fuel's the easy part.  You probably gas up your vehicle yourself and, if you're like most drivers, price is a big factor in what you put in your vehicle. Maybe you think it doesn't matter what kind of gasoline you buy, but one major automobile association has found it does make a big difference.  Their study showed that the additives that are put in different brands can affect your vehicle's performance.  Certain gasoline retailers sell gasoline that meets performance standards called Top Tier.  The detergents used in Top Tier gasoline help protect newer engines from carbon buildup and deposits on intake valves, all things that can affect how smoothly your engine runs, how it accelerates and what kind of fuel economy you get.  You can check online or ask your serv ... read more

If you saw a dollar bill on the ground, you'd pick it up, right? Well, whether you find that dollar on the ground or in savings at the gas pump, money is money, and here are some ways to hold on to more of it. Slowing down is the easiest way to save fuel, especially for every speed increase over 50 mph/80 k/hr.  Tone down the speed, turn up the cash savings.  Drive smoothly (not like a race car driver) and you'll also save money in fuel.  Aggressive, fast-start, jerky-stop habits are just pulling the bucks out of your wallet about a third more than if you drove just a little more gently.  Oh, and cruise control can help with that smooth, steady speed, so use it on the highway. Bonus! Are you hauling around a set of dumbbells or a box of books? That extra weight is costing you dough.  Store them somewhere else.  When's the last time you checked to see your tires were inflated properly? That's another money saver and makes your vehicle safer. An idle thought ... read more

Everybody's got friends like this.  You know, the kind who, the minute they get in their vehicle and turn the key, the sound system is deafening.  They just love to hear that music, sports, news… anything but the sound of the vehicle itself. And maybe you're that person, too.  Here's something to consider: your sound system might be drowning out some valuable clues that could help you diagnose problems with your vehicle, problems that need to be dealt with. So, turn down the volume and listen for these things: A clicking sound when you're braking or turning—You could be missing some parts in your braking system, or it could be damaged. That sound could also signal that components are just plain worn out. Rattling under the hood—If it sounds like metal clanking against metal, you could have something serious going on, maybe an overheating engine or your timing needs adjusting. That knocking sound could also be as simple as you've been using lower octan ... read more
