How many cylinders is Lexus 250?
The answer depends on the model. The IS 250 uses a six-cylinder V6, while the NX 250 uses a four-cylinder inline-four engine.
What the badge typically signals across models
In Lexus nomenclature, the number in a badge like "250" can refer to different engine configurations depending on the model and generation. Here are the two most common interpretations you’ll encounter for "Lexus 250."
IS 250 — six-cylinder configuration
The IS 250 badge was used on mid-2000s to early-2010s Lexus IS sedans in many markets. It denotes a 2.5-liter V6 engine with six cylinders.
- Engine: 2.5 L
- Cylinder arrangement: V6 (six cylinders)
- Typical production years in the US: roughly 2005–2013
In this era, the “250” badge corresponds to a V6 powerplant, not a four-cylinder setup.
NX 250 — four-cylinder configuration
In the current NX crossover lineup, the NX 250 uses a 2.5-liter inline-four engine, giving it four cylinders. This is the common interpretation of the NX 250 badge in recent years.
- Engine: 2.5 L
- Cylinder arrangement: Inline-4 (four cylinders)
- Typical production years: 2020s to present in many markets
Here, the “250” badge designates a four-cylinder engine rather than a V6.
Other notes
Some markets or older variations may have used the 250 badge with different engine configurations. If you’re inspecting a specific vehicle, check the exact engine code or the official manufacturer specs for that model year and market.
Summary
There isn’t a universal answer to “Lexus 250” because the badge spans more than one model. IS 250 is a six-cylinder (V6) model, while NX 250 is a four-cylinder (inline-4) model. Always verify the specific model year and market to confirm the engine configuration.

What are the common problems with a Lexus IS 250?
Common problems with the Lexus IS 250 include carbon buildup in the engine, which can cause misfires, and various electrical issues like malfunctioning radio, climate controls, and window switches. Other frequent complaints involve discolored interior rear-view mirrors, a clicking noise from the rear suspension, and sometimes wet carpets due to a clogged A/C drain tube.
Engine issues
- Carbon buildup: The direct injection system is prone to carbon deposits on the intake valves, which can lead to misfires and other drivability problems. This is more common in pre-2010 models and can be exacerbated by using regular gasoline and excessive idling.
- Oil sludge/consumption: Infrequent oil changes can lead to oil sludge, oil consumption, and potential damage to the catalytic converter.
- Engine misfire codes: The check engine light may illuminate with codes like P0300-P0306, which indicates a misfire.
Electrical and interior problems
- Faulty electronics: Owners have reported a wide range of electrical issues, including the radio randomly shutting off, malfunctioning gear shift lights, and non-functional memory seats.
- Discolored interior mirror: The inside rear-view mirror may become discolored over time.
- Sticky dashboard: Some models have a sticky dashboard material, and recall parts may have been unavailable.
- Wet carpet: A clogged A/C drain tube can cause water to leak into the car, resulting in wet carpets.
Other mechanical issues
- Rear suspension noise: A clicking sound from the rear suspension is a reported problem for some owners.
- Transmission problems: Neglecting regular fluid changes can lead to transmission slipping issues.
- DPF and EGR (Diesel models): On diesel models, the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) can become blocked with carbon soot.
