2024 Subaru Legacy: what breaks, and at what mileage
What breaks on the 2024 Subaru Legacy
On the 2024 Subaru Legacy, the failure owners report most often is infotainment screen failure, with 6 reports on file. Across every failure mode on this year, half the dated reports were filed before 15,000 miles. Overall it scores 68 out of 100, high risk for a 2024.
High risk for a 2024 — 184th riskiest of the 226 2024 vehicles we can rate. 29 owner reports; fleet size borrowed from other years of the same model.
What owners report breaking
Owners have reported 12 named failure modes on the 2024 Subaru Legacy, and the three most-reported carry 41% of everything filed.
Infotainment screen failure leads with 6 reports and about 0.2 per 1,000 vehicles.
Lane keep or steering assist fault follows with 3 reports.
Other visibility problem follows with 3 reports.
By system, the reports fall mostly into adas (8), infotainment (6) and glass (3).
The mileage the reports cluster at
Too few of the reports on this year carry an odometer reading to describe the timing: 1 of them do. The mileages quoted elsewhere on this page come from the modes that have enough of them.

Severity, and what it costs
Nothing in the reports on the 2024 Subaru Legacy 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 3.10, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. 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: infotainment screen failure at $400–$2,600, lane keep or steering assist fault at $200–$1,600, other visibility problem at $150–$1,400 and automatic braking for no reason at $0–$1,500. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
3% 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 2024 Subaru Legacy draws about 1.1 per 1,000 vehicles, which puts it in the 76th percentile of complaint rates among 2024 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 27,440 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2024 vehicles, which is what the risk score uses, is far more robust than the rate itself.
How it ranks in the 2024 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.

Better and worse years of the same car
High risk for a 2024 — 184th riskiest of the 226 2024 vehicles we can rate. Because the ranking is against the same model year only, age cancels out of it.
Across the 28 model years of this car that carry enough reports to score, 1996 comes out best at 60 and 2015 worst at 78, with 2024 itself at 68.
If the model year is negotiable, 1996, 1999, 1997 and 2000 score lower than 2024 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.
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.
The limits of complaint data
29 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 29 reports, 1 carried an odometer reading, so the mileages here describe 3% 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.
Questions this page answers
What are the most common problems with the 2024 Subaru Legacy?
The most-reported failures are infotainment screen failure (6 reports), lane keep or steering assist fault (3 reports) and other visibility problem (3 reports). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 2024 Subaru Legacy reliable?
It scores 68 out of 100 on our risk index, which is high — 184th riskiest of the 226 2024 vehicles we can rate. The score is a comparison against other 2024 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
