2015 Lexus IS 250: what breaks, and at what mileage
What breaks on the 2015 Lexus IS 250
On the 2015 Lexus IS 250, the failure owners report most often is no-start or intermittent start failure, with 2 reports on file. Across every failure mode on this year, half the dated reports were filed before 25,000 miles. Overall it scores 60 out of 100, elevated risk for a 2015.
Elevated risk for a 2015 — 270th riskiest of the 273 2015 vehicles we can rate. 20 owner reports; fleet size borrowed from other years of the same model.
The failures owners actually file about
Owners have reported 9 named failure modes on the 2015 Lexus IS 250, and the three most-reported carry 30% of everything filed, which is an unusually even spread for one model year.
No-start or intermittent start failure leads with 2 reports and about 0.1 per 1,000 vehicles.
Audio or connectivity failure follows with 2 reports.
Other electrical problem follows with 2 reports, median 35,000 miles.
By system, the reports fall mostly into engine (3), infotainment (3) and electrical (2).
At what mileage it happens
14 of the reports on the 2015 Lexus IS 250 came with an odometer reading, and half of those were filed before 25,000 miles.
Cumulatively, 79% by 50,000 miles of the dated reports had been filed.
The busiest stretch is between 0 and 10,000 miles, which alone holds 29% of the dated reports.
50% of the dated reports were filed below 36,000 miles, which is early enough that a fair number of these cars were still under a factory warranty when the owner complained.

What happens when these parts fail
Nothing in the reports on the 2015 Lexus IS 250 mentions a crash, a fire or an injury. That is the ordinary case and it is worth stating: most defect complaints are about a car that stopped working, not one that hurt somebody.
The average severity weight across every report on this year is 2.65, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: no-start or intermittent start failure at $200–$1,800, audio or connectivity failure at $150–$900, other electrical problem at $250–$2,000 and other body or interior problem at $200–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
15% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2015 Lexus IS 250 draws about 0.5 per 1,000 vehicles, which puts it in the 73rd percentile of complaint rates among 2015 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model.
The working figure is 36,552 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2015 vehicles, which is what the risk score uses, is far more robust than the rate itself.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
No-start or intermittent start failure
I was driving and out of no where my indicator light said low voltage steering. I waited a couple of days to get an oil change and have the car inspected and the service guy wrote up the order. I gave the service guy my keys and noticed he never moved the car, I questioned him as to why and he said the car won't start. I replied to his statement and said how is that I just cut it off. The service guy had a tech test the battery and couldn't read it because the voltage was extremely low.

Other electrical problem
Two weeks after buying the vehicle I began to notice that the driver's side door would often time take two or more tries to open with either pulling the door handle or using the keypad. The problem was intermittent in nature and my work schedule was busy so I dealt with it until the problem got significantly worse. The car got to the point in which on 11/27/2015 I recorded a video attempting to get into the vehicle to document my concern .I took the vehicle to the dealership on 11/28/2015 because I figured the issue required immediate attention and I was told that I needed an appointment of which the only convenient appointment was for the next week 12/5/2015. I spoke to andre my service advisor about the issue and left the vehicle for service. By 1 pm that saturday I received a call from andre saying that the issue could not be recreated and that I would basically have to come to pick the vehicle up. I told him that I live in boca and had very limited time during the week. He said he would talk to a manager to basically get permission for the repair. The issue was diagnosed as a problem with stretching of the door cable assembly…

Upon inspection, the contact discovered that electrical connections located in the trunk space were submerged in water. The cause of the water intrusion was not yet determined. The local dealer and manufacturer were notified of the failure and advised the contact to schedule a service appointment. The contact was concerned that with the electrical connections submerged in water, it could cause a fire and safety hazard. The vehicle was not repaired. The failure mileage was 69,000.
How it ranks in the 2015 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse
- Marker this vehicle
Where 2015 sits in the model line
Elevated risk for a 2015 — 270th riskiest of the 273 2015 vehicles we can rate. Because the ranking is against the same model year only, age cancels out of it.
Across the 9 model years of this car that carry enough reports to score, 2015 comes out best at 60 and 2011 worst at 75, with 2015 itself at 60.
No other year of this model scores meaningfully better than 2015, so if this generation is what you want, the year is not the lever.
Within the 2013–2016 generation specifically, 2015 is the strongest year at 60 and 2014 the weakest at 68.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2013-2016 generation, 2015 Lexus IS 250 scores best at 60 and 2014 Lexus IS 250 worst at 68.
What this page cannot tell you
20 owner reports; fleet size borrowed from other years of the same model. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 20 reports, 14 carried an odometer reading, so the mileages here describe 70% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
