• New Spark Plugs or Plug Wires are required for your 2020 Buick Regal. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will experience a noticeable poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more expensive repairs.
• Your 2020 Buick Regal has a vacuum leak. Every Buick Regal has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower adverse emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, especially if they’re exposed to intense heat or extreme cold.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more immediately and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2020 Buick Regal's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the explicitly correct combination of air and fuel that enters the cylinders in your engine. A broken O2 sensor can again cause a vehicle to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2020 Buick Regal if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Regal to Buick and have our team of accomplished certified mechanics assure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could help you save considerably from having to get poor work and damage caused by poor installation work corrected.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2020 Buick Regal’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is usually caused by constantly neglected maintenance, which is why Coggin Buick/GMC of Orange Park offers a free multi-point examination with every Buick service. If you have an issue with your catalytic converter and don't get it repaired, your 2020 Buick Regal will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other delicate problems from overheating.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Buick Regal is what determines how much fuel is required to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Buick Regal is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a crucial sign of a broken mass airflow sensor.
• One of the most common and frequent cause is that your 2020 Buick Regal gas cap is loose, broken or missing. The gas cap for your 2020 Buick Regal serves numerous purposes. It prevents hazardous gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a broken fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more pricey. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on rapidly after you put gas in your 2020 Buick Regal, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• The battery is low or dead. The battery in your 2020 Buick Regal is every crucial. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone.
