Will You Buy a Used Car With Engine Light On

In the world of car buying, it’s important to be aware of any engine light warnings your car may have. If you see an engine light warning, it means that there is a problem with one or more of your car’s parts and that you should take it to a mechanic as soon as possible. Here’s what you need to know about engine light warnings and how they can impact your car buying decisions.

What is a Used Car With Engine Light On?

If you see a used car with an engine light on, there’s a good chance the light is just a warning. A lot of times, the light will just come on when the car is serviced or when it’s been in an accident. However, if the light is on constantly, it might be a sign that there’s something wrong with the engine. If you’re thinking about buying a used car, it’s important to check the engine light to make sure everything is okay.

Types of Used Cars with Engine Lights On

When you’re shopping for a used car, it’s important to be aware of the types of cars that have engine light on. While all used cars can have problems, some cars are more likely to have issues than others. Here are four types of used cars that are more likely to have engine light on:

1. Crossovers: Crossovers are popular vehicles because they can be used for a variety of purposes. However, they’re also built with a lot of heavy components, which can lead to problems down the road. One common problem with crossovers is the fuel pump. Over time, these pumps can wear out and cause the car to stall or fail to start. If you’re looking for a used crossover, be sure to check the engine light status before you buy.

2. SUVs: SUVs are similar in many ways to crossovers, but they’s also popular for carrying heavier loads. This combination can lead to problems with the suspension and drivetrain. SUV engines also tend to generate more heat than other types of engines, which can cause them to overheat and fail. Again, be sure to check the engine light status before you buy an SUV used car.

How to Check if a Car has an Engine Light On

If you’re shopping for a car, it’s important to know whether or not the engine light is on. The light may come on due to a variety of problems, but it’s usually an indicator that you should take the car in for inspection. Here are four ways to check if the engine light is on:

1. Look for a warning light on the dashboard. This light may indicate that there is an issue with one or more of the car’s engines.
2. Check the odometer. If the car has been driven recently and the mileage has changed, there may be an issue with one of the engines.
3. Use a digital voltmeter to test for voltage at specific points on each engine’s wiring harness. If there is insufficient voltage at any point, this could be an indication of a problem with the engine.
4. Open up each hood and inspect each engine for signs of damage or malfunctioning parts.

What to Do If You Find a Used Car with an Engine Light On

If you find a used car with an engine light on, there are a few things you can do to ensure the car is safe to drive and the problem can be resolved.

First, try to determine the cause of the light. If it’s due to a mechanic’s error, the car may still be safe to drive. However, if the light is caused by something more serious, like a broken part that needs to be fixed, then you should take the car in for service.

If the problem is minor and can be fixed at home or by a mechanic without taking the car in for service, it’s worth trying to do so. However, if the issue is more serious and requires taking the car in for repair, be sure to get a written estimate from the mechanic before making a decision. This will help avoid any surprises down the road.


When it comes to buying a used car, it’s important to be aware of the engine light on symbols. While they don’t always mean there is something wrong with the car, they are a signal that you need to take it in for inspection. If you plan on purchasing a used car, be sure to ask the seller about the engine light and whether or not it needs to be fixed before you make your decision.
