Why Does My Battery Die When Not Driven? We have had customers come in complaining of a dead battery. Upon questioning we find that sometimes the customer does admit that it has been 2 to even 4 weeks or more since they last drove. Even worse are the cars that only drive once a month or less. On the downside this is normal behavior for modern cars with all the electronics and convenience features they have. On the upside there are things that you can do to help with this issue. Why a Battery Dies While the Car Is Parked Even when your car is off, systems like the security alarm, infotainment memory, and emission monitors stay active. These things and how they operate varies by car make model and options package. Most cars have some amount of energy use off which is also called parasitic draws. Most vehicles start out when they are first turned off with a relatively high draw. But as the systems power down and finish doing all the tests and other things they do it tapers down to a lo ... read more

Heater Core Repair in Concord, NH – Keep Your Car Warm This Winter Winter here in Concord, NH, can be brutal, and the last thing you want on a frosty morning is a windshield that will not defrost. If you have ever wondered how the car gets your cabin nice and toasty? It’s a device called the heater core, a small radiator tucked behind your dashboard. Even most hybrids and EV vehicles have one, although some newer ones use other devices we will not cover here.

Why Is Steam or Vapor Coming Out of My Car Vents? Have you ever turned on your car’s air conditioning or heater and noticed steam, mist, or smoke coming out of the vents? It can look scary, but it isn’t always a sign of a serious problem. Sometimes it’s harmless, but other times it means your vehicle needs attention. At Accomplished Auto in Concord, NH, we want you to know what’s normal, what’s not, and when to bring your vehicle in for service. Harmless Condensation One of the most common reasons for seeing vapor is condensation. On hot and humid days, cold air from your A/C can make moisture in the air turn into tiny water droplets. That mist can look like smoke, but it’s usually nothing to worry about. If it happens once in a while and goes away quickly, it’s most likely just water vapor. However, moisture that sits in your vents for too long can lead to mold and mildew, which causes musty odors inside the car. Running the fan for a few m ... read more

New England’s Tough Driving Conditions: Why Follow Your Car’s Severe Service Schedule Are you confused about how often to service your car? You’re not alone. The simplest answer is: follow the maintenance schedule in your owner’s manual (or the one your service center provides for your specific vehicle). Every car has its own recommended service intervals these days, and the old one-size-fits-all rules are long gone. For example, oil change recommendations from manufacturers can vary anywhere from 3,000 miles to 15,000 miles depending on the engine and oil type. But here’s the truth: The 3,000-mile interval was for much older vehicles – and there are very few of those left on the road in our area. The 15,000-mile extended intervals will usually get you through your warranty, but in our experience they often lead to sludge buildup and engine issues over time. That ... read more
