High points of this version of the Lexus IS include eye-catching styling and a silky smooth V6 . Performance is rather pokey though. We originally tested the 2.5-liter V6 version, which delivered just 21 mpg overall. Beginning with the 2016 model year, the 2.5-liter was replaced by a turbocharged, 2.0-liter four-cylinder engine and fitted to a new trim line: IS 200t.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2015 Lexus IS owners. The owner comments describe problems respondents experienced with this vehicle.

Body Integrity

Squeaks, rattles, wind noises, loose or cracked seals and/or weather-stripping, air and water leaks.

What Owners Say

Seals and/or weather-stripping

"The weather seal on the sunroof became unattached and had to be glued and reseated"

Todd T., TX (2015 Lexus IS 250 2.5-L V6)
Squeaks or rattles

"Passenger window rattle. Under-hood rattle"

Bruce M., CA (2015 Lexus IS 350 3.5-L V6)

"There was a occasional rattle that caused me to take the vehicle in for inspection. Lexus discovered the issue in quick order and fixed the issue at no cost to me"

John W., CA (2015 Lexus IS 350 3.5-L V6)

"There is a rear suspension rattle when going over bumps"

Anonymous, FL (2015 Lexus IS 250 F sport 2.5-L V6)
Wind noise

"The wind noise was related to the occasional rattle and was fixed with the other issue"

John W., CA (2015 Lexus IS 350 3.5-L V6)

"Stock tires are terrible. Poor balancing, lasted only 18000 miles. When I replaced them (what I felt was way too early), the new tires made the car drive like never before. Quieter, smoother, a lot less noise especially. Crazy that Lexus puts so low quality tires on a $48,000 car. Once I replaced the Bridgestone performance tires with Michelin performance tires (not even top of the line) - the car feels like an entire upgrade took place! Road noise is especially impacted, and smoother ride is really noticeable."

Anonymous, WA (2015 Lexus IS 250 F sport 2.5-L V6)

"TOO MUCH WIND NOISE AT FREEWAY SPEEDS SAME AS ON THE 2014 MODEL"

I replaced brakes at 30k miles with a different dealership service dept saying same thing, must replace brakes more frequently than normal on this model"

Anonymous, TX (2015 Lexus IS 2.5-L V6)

"It went from .5 to .3 in the few months since I purchased it and the brakes squeak consecutively"

Anonymous, ON (2015 Lexus IS 350 F Sport 3.5-L V6)

Anonymous, GA (2015 Lexus IS 350 F Sport 3.5-L V6)
