Buick Enclave
What the car is
The Buick Enclave is a three-row premium crossover built by GM on the C1 platform, made at Lansing Delta Township, Michigan. The third generation launched for 2025, replacing the 3.6-liter V6 with a turbocharged 2.5-liter four (LK0, 328 hp / 326 lb-ft) paired to an 8-speed automatic, with front- or all-wheel drive. It carries the largest-in-class 30-inch combined infotainment display, available Super Cruise (the first Buick to offer it), and a standard trailering package from 2026 (5,000-lb max tow). 2026 trims: Preferred, Sport Touring, Avenir; pricing after the December 2025 adjustment runs $48,395 (Preferred FWD) to $61,995 (Avenir, destination $1,995 included). 2026 adds a key-card entry feature, new paint colors, and expanded rear-camera-mirror availability. Sold in the US and China.
Social-first owner evidence
- Facebook groups "Buick Enclave Owners and Enthusiasts", "2025+ Buick Enclave", "Buick Enclave Fans", and "Buick Enclave Problems" are the main owner hubs.
- In the problems/transmission-oriented group: a 2019 owner reported a $10,000 transmission replacement at 125,000 miles; a 2021 Avenir owner reported undercarriage creaking; older-model threads repeatedly center on transmissions, timing chains, and no-start issues — lineage context, not proof about the new generation.
- 2025 third-generation owner/review evidence: complaints include blank infotainment screens, squeaky brakes, and one sunroof-detachment report; TSB-tracked issues with a damaged torque-converter turbine-shaft seal (code P2817, slipping, delayed/rough shifts, fluid leaks).
- 2025–2026 AWD fault: "Service AWD/4WD" warning with code U3000 Sym 92; temporary battery-reset remedy while GM engineering investigates, with no permanent fix at reporting time.
- Consumer Reports signal for the 2025: below-average predicted reliability; the Enclave lost its CR Recommended rating (GM Authority, March–May 2026).
- A 2024 owner complaint described a failed radio receiver on national backorder, disabling the camera and audible warnings — evidence of GM parts-pipeline strain carrying into the new generation's era.
Reliability record
- Third-generation (2025+) early issues: torque-converter seal TSB (P2817), AWD service warnings (U3000 Sym 92), infotainment blanking, brake squeal. First-year-redesign risk is the defining reliability story.
- Second-generation (2018–2024) lineage: transmission replacements ($10,000 at 125k miles reported), timing-chain and no-start complaints on older builds.
- Recalls: no Enclave-specific recall campaign numbers were verified in collected evidence — check VIN at NHTSA.
- Used-market signal: a one-year-old 2025 averaged $41,191 and a three-year-old 2023 $33,462 (thehealthyattitude.com, citing market data, September 2026) — steep early depreciation consistent with below-average reliability perception.
Support reality
- Buick dealer network services the Enclave; Super Cruise-equipped cars need dealers with current calibration tooling.
- Parts delays documented in the GM ecosystem: radio receiver on national backorder (2024 owner case); Optiq Wi-Fi module six-month wait is a sibling-brand warning sign for new-tech GM parts.
- Warranty: 4-year/50,000-mile bumper-to-bumper, 6-year/70,000-mile powertrain (US). Super Cruise requires subscription after included period.
- The U3000 AWD fault's "battery reset" workaround with engineering still investigating suggests owners may live with intermittent faults for months.
Hype flags
- "Most powerful Enclave ever" (328 hp) is true on paper but comes from a turbo four replacing a V6; long-term durability of the downsized powertrain under 5,000-lb towing is UNVERIFIED by owner evidence.
- The 30-inch display is class-leading in size, but blank-screen complaints undercut the tech-leader story.
- Claims that 2026 resolved the 2025 first-year issues are UNVERIFIED — the powertrain carries over and the AWD fault spans 2025–2026.
Model-year timeline 2021–2026
| Year | Generation & changes | Reliability notes | Recalls/TSBs | Used-price band |
|---|---|---|---|---|
| 2021 | Second generation continues; 3.6L V6 + 9-speed. | Lineage issues: transmission complaints, undercarriage creaking (Avenir owner report). | Check VIN; no campaign verified in collected evidence. | US: ~$30,000–$34,000 est. (band approximate, Sept 2026) |
| 2022 | Second generation; minor updates. | Stable late-gen year; fewer severe complaints than early second-gen. | Check VIN; no campaign verified in collected evidence. | US: ~$32,000–$36,000 est. (approximate, Sept 2026) |
| 2023 | Second generation; final full year. | Mature powertrain; owner sentiment best of second-gen run. | Check VIN; no campaign verified in collected evidence. | US: ~$33,462 avg (market data, Sept 2026) |
| 2024 | Second generation; final year. | Radio-receiver backorder case; otherwise late-gen stability. | Check VIN; no campaign verified in collected evidence. | US: ~$37,000–$41,000 est. (approximate, Sept 2026) |
| 2025 | All-new third generation: 2.5T four, 8-speed, 30-inch display, Super Cruise. | First-year risk: torque-converter seal TSB (P2817), AWD U3000 fault, infotainment blanking; CR below-average predicted. | TSBs for P2817/U3000; recall campaigns UNVERIFIED — check VIN. | US: ~$41,191 avg one-year-old (market data, Sept 2026) |
| 2026 | Carryover; key card, new colors, standard trailering pack; $48,395–$61,995. | Carryover powertrain; watch whether 2025 faults persist. | None documented at collection time — verify by VIN. | US: new $48,395–$61,995 (Dec 2025 adjusted MSRP, incl. $1,995 DFC) |
Raw quotes
- "$10,000 transmission replacement at 125,000 miles" — 2019 Enclave owner, Facebook problems group (paraphrase).
- 2021 Avenir owner, Facebook group (paraphrase): undercarriage creaking noise, unresolved in thread.
- 2025–2026 AWD fault (paraphrase from TSB-tracked reports): "Service AWD/4WD" warning, code U3000 Sym 92; temporary fix is a battery reset while engineering investigates — no permanent remedy at reporting time.
- Torque-converter TSB (paraphrase): damaged turbine-shaft seal causing slipping, delayed/rough shifts, fluid leaks, code P2817.
- 2024 owner complaint (paraphrase): radio receiver failed and replacement was on national backorder, disabling the backup camera and audible warnings.
- Market analysis (thehealthyattitude.com, Sept 2026): "a one-year-old 2025 Enclave averages $41,191… a three-year-old 2023 model drops to $33,462" — steep early depreciation.
- GM Authority (2026): the Enclave "has lost the Consumer Reports 'Recommended' rating."
