Diagnosing Vehicle Issues: Why Further Work Is Sometimes Necessary At Accomplished Auto, we take great pride in our ability to diagnose and repair your vehicle with precision and care. However, we want to share some insight into why, on occasion, additional problems may surface after an initial repair is completed. Modern vehicles are incredibly complex machines, equipped with multiple computer systems constantly monitoring various subsystems, especially emissions and safety-related components. These computers are designed to ensure your vehicle operates cleanly, efficiently, and safely. When a fault occurs in one system, the vehicle's onboard computers often continue to monitor the issue to see if it self-corrects. However, many diagnostic tests depend on other systems being fully operational before they can run. As a result, when we repair one problem, it often allows the vehicle to complete tests that were previously blocked by the initial fault. For example, if your vehicle ... read more

As the summer heat sets in, there’s nothing more frustrating than turning on your vehicle’s air conditioner and realizing…it’s not blowing cold air. At Accomplished Auto in Concord, NH, we hear this question all the time. The good news? You’re not alone—and we’re here to help. Understanding the A/C System Basics Your vehicle’s air conditioning (A/C) system relies on refrigerant—a gas that circulates through components like the compressor, condenser, and evaporator—to create cool air. But a number of issues can disrupt this system. Let’s break down the most common culprits. 1. Refrigerant Leaks: The Most Common Problem The A/C system must be completely sealed to function correctly. Unfortunately, small leaks in hoses, seals, or couplers can allow refrigerant to escape. Even a pinhole can cause enough loss over time to prevent the system from cooling. Federal law requ ... read more

This includes components such as catalytic converters and smog pumps ... read more

Your car has several filters working quietly in the background to protect key components and keep everything running as it should. While oil changes and brake inspections often get top billing during routine service, these filters play a crucial role in engine health, fuel efficiency, and cabin comfort. Ignoring them can lead to reduced performance, premature wear, and costly repairs. Let’s take a look at the five most important filters in your vehicle and why they should be a regular part of your maintenance schedule. 1. Engine Oil Filter Every time you drive, your engine oil picks up dirt, metal shavings, and carbon deposits. The oil filter traps these contaminants and keeps them from circulating back through the engine. If the filter becomes clogged or too old, it won’t do its job effectively, and dirty oil can cause damage to engine bearings, pistons, and other moving parts. Changing your oil filter along with the oil is essential. Skipping the filt ... read more
