Model Years to Avoid

Among the Lexus IS 250 model years to avoid, the 2007, 2008, and 2006 models stand out as the worst due to several common issues.


This particular model year has been reported to have problems with its dashboard, leading to crack formation.

In addition to this, the 2007 Lexus IS 250 is known for having issues with the inoperable wiper arms. In situations with lowered road visibility, these wiper issues can be a serious safety concern for you and your passengers.


The 2008 model year has been flagged for its carbon buildup issue in the engine, which can result in poor acceleration and reduced fuel efficiency.

This problem can be costly to repair and may lead to ongoing maintenance for you as the owner.


The 2006 Lexus IS 250 is known to have issues with excessive oil consumption. This model year tends to consume oil quicker than others, leading to more visits to the mechanic for regular oil changes.

This can be both a financial and time-consuming inconvenience for you.

Reviews and Cons

In your search for a Lexus IS 250, it’s important to weigh the cons and reviews. Some common problems include surging RPMs when stopped, excessive vibration and shaking, and cylinder misfire codes.

As a result, you might face issues like poor fuel economy and sluggish throttle response.

When reading owner reviews, pay attention to factors like reliability, performance, and value for money.

Remember, Lexus IS 250 models with aluminum fuel delivery pipes might face corrosion and fuel leaks, which can be a fire hazard.

Performance and Handling


The Lexus IS 250 has a 2.5-liter V6 engine, which can experience excessive carbon buildup issues, affecting its smoothness and performance. This is more common in the 2006 to 2010 models.


While there aren’t any major braking-related issues reported, it’s essential to maintain your Lexus IS 250’s braking system for safe and reliable handling.

Remember to check your braking system regularly and ensure well-maintained roads for your driving experience.

Safety Features

Your Lexus IS 250 comes equipped with a variety of safety features to keep you protected on the road. One of the key safety aspects includes airbags to cushion the impact during a collision.

Driver and passenger front airbags, side airbags, and curtain airbags all work together to provide you with comprehensive protection.

It’s important to note, though, that even with these features, practicing safe driving habits and regular car maintenance are essential for your safety on the road.

Fuel Consumption

As a Lexus IS 250 owner, you might be interested in its fuel consumption. The IS 250 is known for its efficient engine and performance capabilities.

However, like any vehicle, it can experience issues related to fuel consumption. In this section, we’ll discuss some of the factors that can impact your Lexus IS 250’s fuel efficiency.

Malfunctioning oxygen sensor

One common problem that may affect your IS 250’s fuel consumption is a malfunctioning oxygen sensor.

The oxygen sensor monitors the level of unburnt oxygen in the vehicle’s exhaust gases and helps balance the air-to-fuel ratio for optimal engine performance.

If this sensor isn’t functioning properly, it can lead to a decrease in fuel efficiency. Keep an eye on your Lexus IS 250’s performance, and if you notice any changes, consider having your oxygen sensor checked.

Tire pressure

Another factor that can impact your car’s fuel consumption is tire pressure. Properly inflated tires help reduce rolling resistance and ensure that your Lexus IS 250 is running efficiently.

Make sure to check your tire pressure regularly and inflate them to the manufacturer’s recommended level. You can find this information in your Lexus IS 250 owner’s manual.

Bad driving habits

Additionally, your driving habits can greatly affect your Lexus IS 250’s fuel consumption. Aggressive driving, such as rapid acceleration and excessive braking, can waste fuel and reduce your car’s overall efficiency.

Try to maintain a consistent speed, and avoid sudden changes in acceleration to help optimize your Lexus IS 250’s fuel consumption.

In summary, a well-maintained Lexus IS 250 engine will lead to more efficient fuel consumption.

First and Second Generations

Friendly advice for you, Lexus IS 250 owner! While the First Generation (2001-2005) had a solid reputation, the Second Generation (2006-2013) encountered some issues.

In the Second Generation, the 2006-2008 model years faced the most problems. One prevalent issue was melting dashboard and door panels due to heat in some climates. Furthermore, the infotainment systems often malfunctioned.

Meanwhile, the First Generation Lexus IS 250 had a smooth run. So, if you own a Second Generation model, it’s worth keeping an eye on these specific areas. Stay informed and enjoy your car!
