2024 Buick Enclave: what breaks, and at what mileage
What breaks on the 2024 Buick Enclave
On the 2024 Buick Enclave, the failure owners report most often is seat belt or retractor failure, with 2 reports on file. Across every failure mode on this year, half the dated reports were filed before 45,000 miles.
What owners report breaking
Owners have reported 7 named failure modes on the 2024 Buick Enclave, and the three most-reported carry 45% of everything filed.
Seat belt or retractor failure leads with 2 reports and about 0.0 per 1,000 vehicles.
Other engine problem follows with 2 reports, median 45,000 miles.
Excessive oil consumption follows with 1 report.
By system, the reports fall mostly into engine (3), airbag (2) and electrical (1).
When these failures get reported
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.

How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A curve that climbs early is a car with early problems, whatever its total.

Severity, and what it costs
Across the named modes, 2 mention a crash 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 5.82, 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: seat belt or retractor failure at $200–$900, other engine problem at $300–$4,000, excessive oil consumption at $900–$6,500 and control module (ECM/PCM/BCM) failure at $700–$3,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
36% 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 Buick Enclave draws about 0.2 per 1,000 vehicles, which puts it in the 69th 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 66,967 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.
Where 2024 sits in the model line
Across the 17 model years of this car that carry enough reports to score, 2023 comes out best at 61 and 2022 worst at 86.
Within the 2023–2026 generation specifically, 2023 is the strongest year at 61 and 2025 the weakest at 65.
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, 2023 Buick Enclave scores best at 61 and 2025 Buick Enclave worst at 65.
Where these figures stop being useful
11 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 11 reports, 1 carried an odometer reading, so the mileages here describe 9% 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 Buick Enclave?
The most-reported failures are seat belt or retractor failure (2 reports), other engine problem (2 reports, median 45,000 miles) and excessive oil consumption (1 report). 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.
Which year of the Buick Enclave is best?
Within the 2023–2026 generation, 2023 scores best at 61 out of 100 and 2025 worst at 65. 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.
