2015 Buick Enclave — Should You Buy One?

Typical asking price: $11,000–$17,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The plush version of GM's Lambda three-rows, and the pleasantest way to gamble on the wave-plate transmission and timing-chain 3.6L. Quiet, comfortable, and roomy — buy one with documented transmission and timing work, or it's an expensive surprise waiting to happen.

What we checked

Partly reconciled against public records, 2026-09-25

NHTSA holds 171 owner complaints for the 2015 Buick Enclave, and 5 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 61% of them are about one thing — airbags. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

5 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Not written up yet: electrics and electronics (14 complaints). That group is in the public record and is not covered by the issues below. Treat it as something to ask about, not as absent.

Looked at and set aside: airbags (105) — 105 airbag complaints on file, almost always a recall matter rather than a repair bill; have a dealer check this VIN for open airbag campaigns and confirm any were performed.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
