2015 Lexus IS 250 — Should You Buy One?

Typical asking price: $15,000–$21,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

Slow, and that is genuinely the biggest complaint anyone has. The 2.5L V6 is underpowered for the chassis but the car is beautifully built and essentially trouble-free. If you want a small luxury sedan you can ignore for a decade, this is the answer.

Known Issues for the 2015 Lexus IS 250

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Carbon buildup on intake valves (4GR-FSE)Medium

The direct-injected V6 builds carbon, causing rough idle and misfires. Toyota's dual-injection later engines avoid this; the IS 250 does not.

Repair cost range: $600-$1,200

Slow accelerationMedium

204 horsepower in a 3,600-pound car with a six-speed automatic. Not a defect but the reason resale is soft — and the reason it is good value.

Repair cost range: n/a

Water pump seepageLow

Weeping around 120k miles. Routine.

Repair cost range: $500-$900

Dated infotainmentLow

No CarPlay, slow response, and a mouse-style controller in later trims.

Repair cost range: $0-$700

Walk-Away Red Flags

  • Rough idle and misfire codes with no intake cleaning
  • Salt-belt underbody corrosion
  • Modified suspension or exhaust
  • Accident repair on a car bought for build quality

Good Signs

  • Intake valves cleaned with documentation
  • Full Lexus service history
  • IS 350 if you want the same car with adequate power
