Recently, Nissan introduced the latest version of its Leaf, the company's electric car. It has many new features, including something called e-Pedal. It allows the driver to let up on the accelerator and, unlike a gasoline engine car, the Leaf doesn't just slowly lose speed; letting off the throttle pedal brakes the car in a very controlled way, using regenerative and sometimes friction brakes. With practice, a driver can go for a fairly long time without touching the brake pedal. Another system, similar to those found in self-driving vehicles, can steer the car to keep it in the center of the lane using a camera and radar. It literally watches the lane markers and, of course, doesn't work well in snow that obliterates those markers. But the technology is impressive and can greatly reduce fatigue on long trips. In fact, much of this technology has "trickled down" from research on autonomous vehicles, such as adaptive cruise control that slows down your vehicle (even to a stop) if the v ... read more

Think of how much abuse your brakes take. Day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be. Then it's time to get your brakes checked out. After all, you have to be able to stop if you want to be safe. Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime. Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate. It used to be that roto ... read more

You may have had a friend whose vehicle was the victim of hungry rodents.  After all, mice, rats and squirrels—even rabbits—have been known to gnaw on wires in engine compartments, causing vehicle electrical systems to go haywire.  They can disable a vehicle completely and be very expensive to fix. In 2017, some drivers noticed their vehicle's wiring was being chewed and found out the automaker was using a relatively new material for covering their wires: soy.  Many of the repairs to their new vehicles weren't covered under warranty by the manufacturer when it was discovered rodents were eating the wiring.  So the owners filed a class action suit, saying the soy covering was essentially baiting the critters.  The automakers tell a different story, saying mice, rats and squirrels have been chewing through wire insulation long before it was made out of soy.  Regardless of what the insulation is made of, vehicle owners should make sure rodents are ... 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 drive, you know at some point, something's going to go wrong with your vehicle.  And sometimes, it's pretty easy to figure out what's wrong, like a flat tire.  But sometimes your vehicle's symptoms can be really puzzling. One driver in Tennessee was heading to work on a hot July day and noticed when he pressed the accelerator, sometimes it wouldn't do anything. He also noticed his cruise control wouldn't work and his traction control light was constantly on, very unusual. He was trying to figure it out, but none of it made any sense.  His cruise control had always worked perfectly, his traction light never had gone on before and there was never any issue pressing on the accelerator. It was time to take his car in for a professional diagnosis, and boy, was he surprised that it was a freak accident he'd had the previous WINTER that was the root of his problems.  You see, in January, his car had slipped on ice when he was in reverse and had gently tapped a tree ... read more

Perhaps you've found yourself driving when something all of a sudden splashes on your windshield, obstructing your view. You know that sinking feeling when you try to turn on the windshield washers and no fluid comes out. Now you're blinded even more. What can you do? The best thing is to make sure your windshield washer fluid is always topped off and ready for these situations. You probably figure you'll grab a bottle of that blue stuff you see in the store. But is that really the right choice? One thing you know isn't the right choice is plain water. It can freeze when temperatures drop. Plus, when it's close to the freezing mark outside, spraying water on your windshield can freeze, turning it literally into frosted glass and blinding you suddenly. Water freezing in your vehicle's washer lines can also damage them. There are different types of windshield washer fluid made for different climates. Many have alcohol to prevent them from freezing; their label will usually tell you at wh ... read more

You've likely heard how important oil is to your vehicle's engine. Did you know that there's one part that's responsible for holding that oil so you can use it every day? It's called the oil pan, and it sits at the bottom of the engine. The oil pan is a vital, though simple, part of your engine's lubrication system. Oil circulates through parts of your engine to keep them lubricated. It reduces friction so everything works smoothly. Without oil, friction would quickly destroy your engine. The oil pan keeps that oil contained in the lubrication system, so it's important that the oil doesn't leak out. Since it's a metal part attached to another metal part, there is a gasket between the oil pan and the part of the engine it attaches to. Various things can put stress on the oil pan and gasket, including weather extremes, the speed you're traveling and the condition of the oil. You may drive over a couple of bad roads and kick up debris onto your oil pan. All this wear and tear, heat and ti ... read more

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it. A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well. The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to s ... read more

If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB. Here's what a TSB is. Vehicle design and manufacturing is a very complex process. Aftrer every vehicle is introduced, the more units there are on the road, the more likely weaknesses in parts or design will start to show up. Automakers gather data on the issues and how best to fix them. Then they send out TSBs (usually in the first year of the new model) so technicians will know to look for those problems and what to do about them. There may be more than one cause of a problem with a vehicle so there may be more than one TSB for an issue. A TSB can be issued for anything from failing water pumps to strange noises to smelly headliners. A TSB and a recall aren't the same thing. A recall is issue ... read more

If that little brake warning light pops up on your dash, do you know what it means? Well, if you said no, you wouldn't be alone. You know it has something to do with your brakes, but exactly what? You're not sure. One of the reasons is that it could mean a lot of different things. It could be something simple, like you put your parking brake on and forgot to take it off. Easy fix, you're on the road in seconds. Or, it could mean there's something wrong with your anti-lock brake system. That is a pretty complex symphony of speed sensors, computers and wiring, and sometimes things get a little out of whack. You could have a defective sensor or some wiring may have gotten damaged or come loose. A trained technician at Allen's Automotive Center with special equipment can sort it all out. It's also possible you have low brake fluid. That could be caused by a number of things. One simple reason is that your brake pads have worn down. Replacing them could solve the problem. Another possibilit ... read more
