2024 Mazda CX-50: what breaks, and at what mileage
What breaks on the 2024 Mazda CX-50
On the 2024 Mazda CX-50, the failure owners report most often is other body or interior problem, with 5 reports on file. Across every failure mode on this year, half the dated reports were filed before 15,000 miles. Overall it scores 81 out of 100, severe risk for a 2024.
Severe risk for a 2024 — 16th riskiest of the 226 2024 vehicles we can rate. 52 owner reports; fleet size estimated from this year's own recall paperwork.
The failures owners actually file about
Owners have reported 23 named failure modes on the 2024 Mazda CX-50, and the three most-reported carry 25% of everything filed, which is an unusually even spread for one model year.
Other body or interior problem leads with 5 reports and about 161 per 1,000 vehicles.
Lane keep or steering assist fault follows with 4 reports.
Other electrical problem follows with 4 reports, median 75,000 miles. 1 of those report mention a fire.
By system, the reports fall mostly into adas (10), body (5) and electrical (5).
When these failures get reported
10 of the reports on the 2024 Mazda CX-50 came with an odometer reading, and half of those were filed before 15,000 miles.
Cumulatively, 80% by 50,000 miles, 80% by 100,000 miles and 90% by 150,000 miles of the dated reports had been filed, with 1 filed above the top of the chart.
The busiest stretch is between 0 and 10,000 miles, which alone holds 40% of the dated reports.
80% 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.

How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A further 1 report came in above that, which is why the line stops short of the top. A curve that climbs early is a car with early problems, whatever its total.

What happens when these parts fail
Across the named modes, 4 mention a crash, 3 a fire and 2 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 4.50, 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: other body or interior problem at $200–$2,000, lane keep or steering assist fault at $200–$1,600, other electrical problem at $250–$2,000 and other visibility problem at $150–$1,400. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
12% 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.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. 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 Mazda CX-50 draws about 1,677 per 1,000 vehicles, which puts it in the 99th 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. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 31 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.
Recalls on the 2024 model year
NHTSA has issued 1 recall campaign covering the 2024 Mazda CX-50, affecting an estimated 31 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover trailer hitches. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.
TRAILER HITCHES
63 vehicles 2025-03-14- Defect
- Mazda North American Operations (Mazda) is recalling certain 2024-2025 CX-50 vehicles equipped with Mazda Genuine Accessory trailer hitches. The trailer hitch assembly bolts may loosen and cause the assembly to separate from the vehicle body during towing or normal driving conditions.
- Consequence
- A detached trailer hitch assembly can create a road hazard, increasing the risk of a crash.
- Remedy
- Dealers will tighten the trailer hitch bolts, free of charge. Owner notification letters were mailed April 4, 2025. Mazda's number for this recall is 7225C.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
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.
- Left fewer and less serious reports
- Right more, or worse

Where 2024 sits in the model line
Severe risk for a 2024 — 16th riskiest of the 226 2024 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.
Across the 4 model years of this car that carry enough reports to score, 2026 comes out best at 72 and 2024 worst at 81, with 2024 itself at 81.
If the model year is negotiable, 2026, 2025 and 2023 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.
Within the 2023–2026 generation specifically, 2026 is the strongest year at 72 and 2024 the weakest at 81.
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 2023-2026 generation, 2026 Mazda CX-50 scores best at 72 and 2024 Mazda CX-50 worst at 81.
What this page cannot tell you
52 owner reports; fleet size estimated from this year's own recall paperwork. 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 52 reports, 10 carried an odometer reading, so the mileages here describe 19% 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".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
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 Mazda CX-50?
The most-reported failures are other body or interior problem (5 reports, median 100 miles), lane keep or steering assist fault (4 reports) and other electrical problem (4 reports, median 75,000 miles). 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 Mazda CX-50 reliable?
It scores 81 out of 100 on our risk index, which is severe — 16th 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.
Which year of the Mazda CX-50 is best?
Within the 2023–2026 generation, 2026 scores best at 72 out of 100 and 2024 worst at 81. Same body, same engines, different luck.
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.
