Important Warning Signs To Watch For Your Toyota

Failure of your Toyota car, truck or SUV could be frustrating, because it's hard to pinpoint what exactly is causing the problem.

When your car, truck, or SUV experiences failure, it can be difficult to pinpoint exactly what the issue is. The major systems in your vehicle generally exhibit their own unique warning signs which act of signs of failure. Whether the issue is your electrical system, brakes, shocks or struts, or heating and cooling system, knowing what to look and listen for will help you get the issue resolved quickly and with the minimum amount of inconvenience when you stop by Toyota of Greenville.

As the performance of your engine starts to wear down, the system might exhibit warning signs that are unique to your vehicle. Understanding these signs will assist you in identifying when they occur and what to do when it happens. Remember that your engine is an extremely complicated system and requires preventative maintenance. Keep your engine properly tuned up for maximum vehicle performance.

Check Engine Light Activates

An activated check engine light is a powerful tool that is designed to inform you of potential car engine trouble. This light usually illuminates when detecting engine issues stemming from loss of power. These issues range in severity, type, and implications to your vehicle. If your check engine light comes on, Toyota of Greenville recommends getting an engine diagnostic service to determine the issue.

If you do not have your own diagnostic equipment, Toyota of Greenville offers a free code pull. If you know how to use an engine scanner, then simply write down your fault code and bring it with you when you speak to your service technician.

If your check engine light is flashing, we recommend that you stop driving immediately and call for a tow. A flashing light indicates that something potentially serious could be occurring within one of your vehicle's systems. Stay on top of all of the systems in your vehicle by decoding your dashboard.

Loss of Power

Most gas-powered vehicles are designed with an internal combustion engine. These car engines use a four-stroke combustion cycle to convert gasoline into the power needed to make your vehicle drive. The four strokes are the combustion stroke, intake stroke, compression stroke, and exhaust stroke. The loss of power you are experiencing could be stemming from a hiccup from any one of these four steps (strokes) in the combustion process.

Gas Mileage Drop-off

If you notice the distance your gas tank takes you is not what it used to be, it could be an indicator that there is an issue in the compression stroke of your engine. In this instance, having a fuel system service performed or using a fuel cleaner may clear up the issue. Depending on how long it has been, it might be worth considering a tune-up. If these two recommendations do not help with fuel efficiency, having an engine diagnostic performed might provide you with the information and options you are looking for to correct the issue.

Noises Galore

Knocking, hissing, backfiring, spitting and popping are all sounds we do not want to hear when we start our car, truck, or SUV. These noises can occur when there is an issue in the combustion flow. If you are hearing engine knocking, popping, spitting or your vehicle backfires, bring it into Toyota of Greenville ASAP.

Engine Stalling

Many of us who learned to drive on a manual transmission understand the nature of stalling engine. For those who are unfamiliar, when the clutch pedal and gas pedal are not engaged at the right speed, your car will stop and require a restart - a most frustrating and embarrassing event, especially in traffic.

The frequency of stalling for an automatic transmission is far less common and generally serves as an indication that something is seriously wrong with an engine component. This "wrong" can vary but is usually due to the intake stroke not receiving the right spark or air/fuel mixture. If your manual transmission is stalling (and that stall is not due to human error - don't worry, it happens to the best of us) or your automatic transmission is stalling, have it seen by a Toyota of Greenville professional service technician as soon as possible. This stalling can lead to greater issues and the fix might be as simple as having a tune-up performed.


When the exhaust stroke of your internal combustion engine is starting to fail, it could give off a noxious odor from the exhaust. Much like the familiar sounds of imminent failure, this odor is a tip-off that your vehicle needs attention from a professional.

Engine Continues to Run after Ignition is Turned Off

This occurrence, also known as run-on and dieseling, is most common with high-performance vehicles and usually happens when the octane in the gas is not correct. Other culprits could be a failing solenoid or an overactive carburetor. If this is happening with your vehicle, Toyota of Greenville service professionals will have the answers you need to get your vehicle back to maximum performance.

Rough Running Engine

If your engine is running or idling rough the fix might be as simple as a tune-up. The most common cause of a rough running engine is clogs in the system or old spark plugs. Other issues could be an incorrect octane in the gasoline or a low battery.
