How we rated the best and worst Lexus IS 250 years

While in the making of this guide, our team created a unique rating system that enabled us to properly and accurately rate the Lexus IS 250 years as best and worst.

To do that, we focused on official records and complaints submitted to NHTSA, as well as some first-hand impressions and driver reviews that we found on forums and platforms like Edmunds, KBB, and CR.

Most common Lexus IS 250 problems

Over the years, you could hear drivers recommend the IS 350 over the IS 250 and state that this car is more reliable and claim it to be more desirable due to the power gap. While having a 3.5-liter engine is certainly worth it in a sporty body like the Lexus IS, the 2.5-liter engine didn’t have that many troubles.

However, this model is known to have struggled with the wiper arms that are sometimes inoperable under load like snow. Finally, a common issue for all the IS 250 generations is the melting dashboard, so let’s take a look at the most frequent problems that the model owners had to deal with.

1. Fuel delivery system faults

One of the most common problems for the Lexus IS 250 is fuel delivery pipes. Cars equipped with aluminum pipes could end up having corroded pipe interiors and it could lead to a fuel leak. Since the pipes are located in the engine compartment, it’s a dangerous issue that could even lead to a fire hazard.

So, this is the first thing you’d want to pay attention to if you are considering buying a used Lexus IS 250. In case the check engine light illuminates, and there doesn’t seem like anything is wrong with the engine except for the increased fuel consumption, you should check the delivery lines.

2. Airbag problems

Well, this one can be just as annoying as having trouble with the fuel delivery pipes. In both cases, you may not even realize that there’s a safety hazard in your Lexus IS 250, making them equally dangerous. There have been numerous airbag system recalls in the Lexus IS 250, and the last one was in 2019.

The airbag problem is mostly associated with inoperable airbag inflator modules. However, there’s another problem with the airbag system, even for the vehicles that got the airbags replaced during a recall. It’s the safety hazard caused by inflator bags that could cause an explosion after humidity exposure if not used for a while.

Not only is the explosion a bad thing for airbag inflation, but the metal fragments could also end up causing lethal injuries. So, it’s best to check your Lexus IS 250’s airbag system and check if the car has gone through one of the mentioned recalls before buying it.

3. Inoperable wiper arms

This one may sound a bit silly at first, but it’s a serious issue in situations with lowered road visibility. Namely, based on NHTSA’s reports, certain Lexus IS 250 models have faced troubles with the inoperable wiper arms. While you can simply replace the arms yourself, relying on factory-set wipers is a bad thing due to their possible malfunction under heavy loads.

So, even a few cubic inches of snow may end up causing mayhem since you won’t be able to move the wipers to clean the windshield. Don’t worry, Lexus issued an official recall to fix these in 2013, for the IS 250 models produced from 2006 to 2012.

4. Interior material quality

Don’t get us wrong here – the Lexus IS 250 offers a refined and comfortable interior when compared to its competitors in the same class. However, we can’t just ignore numerous driver reports stating that the dashboard tends to melt after a while.

Interior materials are said to be of premium quality by Lexus and Toyota, so it’s an odd occurrence that you may end up having with your car. There was no recall issued for this problem, so you may have to go through a bothersome process of replacing the dashboard.

Worst Lexus IS 250 years to avoid

Lexus IS started its journey back in 1998 with the first generation, but it only offered 2.0-liter and 3.0-liter petrol engines. So, the tradition of the IS 250 model started with the second generation of the IS model, and it continued through the third generation.

To avoid confusion, we’ll simply refer to these second and third generations of IS as a model. Among the model years, it’s crucial to dodge the recalled models with airbag issues and leaking fuel lines, so what are the worst Lexus IS 250 years?

The worst Lexus IS 250 years are 2007 and 2008, but here’s a complete list:

• 2006
• 2008
• 2015

You can take a closer look at the issues that affected the reliability of those models below as we thoroughly explain them.

Second-generation Lexus IS (2006-2008 model years)

The second generation Lexus IS is the first generation of the model to feature the 2.5-liter V6 petrol engine, and troubles have started right from its inception. The 2006 model year is one of the toughest for Lexus when it comes to this model, mostly due to dashboard and interior panels melting, as well as problems with the infotainment module.

Other frequently expressed issues for the second generation IS with the 2.5-liter engine include the mentioned airbag problem that led to numerous recalls by the manufacturer.

Third-generation Lexus IS (2015 model year)

The third and current generation of the Lexus IS is a rather reliable one, and the 2.5-liter engine is one of the most convenient options for maintenance. There are some airbag inflator module and SRS light issues associated with 2015 as the final year of the recall.

Also, this model year is the one to avoid due to fuel delivery system issues and bad aluminum fuel piping. Still, it’s safe to go with the 2.5-liter engine when it comes to engine parts in particular since it has proven to be a smooth engine with just enough power to get the wheels rolling fast when needed and without any standout issues.

What are the best Lexus IS 250 years to buy?

Well, now you at least know that the problems that some drivers refer to as serious disadvantages of the IS 250 when compared to IS 350 aren’t that much trouble. The airbag issue was sorted out for the 2016 and following model years, while the windshield wiper problem was sorted out for the 2013 model year.

Still, it’s best to buy a car and cut the worries by picking one of the best model years in favor of the ones that are not so appreciated. Our team made the list below to recommend some of the most reliable Lexus IS 250 model years:

• 2010
• 2013
• 2014
• 2016
• 2017
• 2018
• 2019
• 2020
• 2021

When it comes to the fuel delivery pipe issue, that issue was most persistent for the 2006 to 2009 model years and was later on sorted out with the next generation and later second-gen model years. That’s why it might be a good idea to skip the mentioned model years and go for one of the listed production years just to be safe. The best Lexus IS 250 model years are 2010 and 2013, so we’ll further discuss those two models.

2010 Lexuxs IS 250

The 2010 Lexus IS 250 is one of the most reliable first-gen IS models with a 2.5L engine and it only had some slight body/paint issues. Other than that, everything else was more than just fine with less than 100 complaints ever being served to NHTSA, which is more than decent for a model more than a decade old.

With great driver reviews and ratings and reliable engine and transmission, the 2010 Lexus IS 250 is a go-to option if you are looking into older models.

2013 Lexus IS 250

As for the facelift models, the 2013 Lexus IS 250 holds its ground pretty well with excellent consumer reviews and only a few reliability complaints. It proved to be a more reliable option when compared with some more recent models like the 2015 IS 250 due to better engine efficiency and overall reliability.

Plus, it’s one of the few model years that didn’t face any issues with recalls as there was just an airbag recall scheduled for this model.

Is the Lexus IS 250 worth buying?

When the time comes to draw the line and decide on whether Lexus IS 250 is a reliable car or not, you have to consider all the items mentioned in this guide. It’s ultimately a great car, especially for those looking for a premium-level sedan with sporty looks and quite some performance.

Sure, it won’t pack the same performance as the IS 350, but if hitting the speed limit as fast as possible isn’t your greatest concern, it’s enough to go with the IS 250 and just avoid the problematic model years.

Our detailed evaluations like BMW 335i years to avoid, Audi A4 years to avoid, Cadillac CTS years to avoid focus on distinguishing the model years that excel in performance, luxury, and dependability from those that are best avoided.
