A 2022 Yukon XL Denali owner on the Tahoe Yukon Forum posted "URGENT" in a thread title after his truck suffered an engine failure. He wasn't alone. GM would go on to recall 597,630 full-size SUVs, including every 2021-2024 Yukon XL with the 6.2L V8, for connecting rods and crankshafts with manufacturing defects that can cause the engine to lose power without warning. A separate recall hit 2022 Yukon XLs for a transmission valve issue that can lock the rear wheels. Neither of those is the widely discussed lifter-tick problem that owners have been trading fixes for since 2021.
The Yukon XL rides on the same T1XL platform as the Tahoe, Suburban, and standard Yukon, and it shares their engines, their electronics, and unfortunately their recall history. What it adds is 14 inches of extra length over the standard Yukon, translating to real cargo room behind the third row. If you're cross-shopping the XL against a Suburban, or you specifically need the longer wheelbase a standard Yukon doesn't offer, here's what four years of forum threads, complaint data, and recall filings say about buying one used.
This Generation at a Glance
The 5th gen Yukon XL (platform code T1XL) launched for 2021 as a ground-up redesign, the first Yukon generation to swap the old solid rear axle for independent rear suspension. That change alone reworked third-row legroom and ride quality versus every Yukon XL before it. GMC refreshed the lineup for 2025 with new front-end styling, a 16.8-inch portrait infotainment screen, a redesigned digital gauge cluster, a column-mounted shifter, and a new 3.0L inline-six diesel (LZ0) replacing the previous LM2 unit.
| Powertrain | Years Available | HP / TQ | Transmission | MPG (Combined) |
|---|---|---|---|---|
| 5.3L V8 (L84) | 2021-2025 | 355 hp / 383 lb-ft | 10-speed auto | 17 (2WD) |
| 6.2L V8 (L87) | 2021-2025 | 420 hp / 460 lb-ft | 10-speed auto | 16 (2WD) |
| 3.0L Turbodiesel I6 (LM2, 2021-2024 / LZ0, 2025+) | 2021-2025 | 277 hp / 460 lb-ft (LM2); 305 hp / 495 lb-ft (LZ0) | 10-speed auto | 23 (2WD) |
The Yukon XL seats up to 9 and offers 41.5 cubic feet of cargo space behind the third row, essentially matching the Chevrolet Suburban and beating the standard-length Yukon by a wide margin. Max towing runs 8,200-8,300 pounds depending on model year and configuration. Every powertrain pairs with GM's 10-speed automatic across RWD and 4WD.
CarScout's own market data shows a wide used-price spread on the 5th gen Yukon XL: high-mileage 2021 examples start around $22,700, while low-mileage 2024 Denalis and AT4s run past $99,000. That range reflects how much trim and powertrain choice matters on this platform more than it does on most SUVs.

Powertrain and Trim Breakdown
5.3L V8 (SLE, SLT, Elevation, AT4)
The 5.3L L84 is the volume engine and the one most buyers on the used market will find. It uses GM's Dynamic Fuel Management system, which can run the engine on anywhere from 2 to 8 cylinders depending on load. The constant cycling of the DFM lifters, collapsing and re-extending dozens of times per second under partial-cylinder operation, is the mechanism behind this generation's best-known complaint: lifter failure.
Owners on the Tahoe Yukon Forum have maintained a dedicated "5.3 & 6.2 Lifter Failures Compilation Thread" tracking cases across both engines. The failure signature is a tick at idle that follows RPM and does not fade at operating temperature. Mileage at failure varies widely; some owners report it under 10,000 miles, others past 100,000. GM has issued technical service bulletins addressing lifter replacement procedures but has not recalled the DFM lifter issue itself on either engine.
When a lifter collapses, it can damage the camshaft lobe it rides on. Lifter-only repairs run in the $3,500-$5,000 range at a dealer; cam damage pushes that toward $10,000-$15,000, and a full engine replacement can run $15,000-$17,000. A popular preventive step among 5th gen owners is an aftermarket DFM/AFM disabler plugged into the OBD-II port, which keeps the engine running on all cylinders full-time and removes the lifter-cycling risk going forward. If you're buying used, ask whether one is installed and whether it stays with the truck.
Forum consensus: The 5.3L is well-liked when it's running right, and the DFM delete is treated as a near-mandatory purchase by owners who want to stop worrying about it. The 10-speed transmission has also drawn complaints about harsh downshifts at light throttle; GM's transmission control valve recall (below) addresses a related but distinct failure mode on 2022 trucks specifically.
6.2L V8 (Denali, AT4X): the recall you have to verify
The 6.2L L87 makes 420 hp and 460 lb-ft and is the standard engine on Denali and AT4X trims. It shares the same DFM lifter hardware and risk profile as the 5.3L. It also carries a serious, separate problem: NHTSA campaign 25V274000, filed in 2025, covers connecting rod and crankshaft manufacturing defects across roughly 597,630 GM full-size SUVs and trucks, including every 2021-2024 Yukon XL built with the L87. The defect can cause unusual engine noise, a check engine light, hesitation or rough running, and in the worst case complete loss of propulsion while driving.
The remedy is a free dealer inspection using diagnostic code P0016 as the flag for crankshaft-to-camshaft misalignment; trucks that fail inspection get an engine repair or replacement, and trucks that pass receive a higher-viscosity oil fill, a new oil cap, and a new oil filter. This is a large-scale recall covering Cadillac Escalade, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL. If a Denali or AT4X you're considering hasn't had this inspection done, that is not optional due diligence: it's the single most important thing to check on this powertrain.
Forum and complaint data: NHTSA complaint filings for the Yukon XL logged engine-related complaints in the dozens for 2021-2023 model years specifically, a pattern consistent with the L87 defect and the DFM lifter issue compounding on the same engine family. Owners who've had the recall inspection completed generally describe the truck as reliable afterward; owners who discovered the problem outside of a completed recall describe expensive, unplanned engine work.
3.0L Turbodiesel Inline-6 (All Trims, Optional)
The diesel returns the best fuel economy in the lineup at 23 mpg combined, versus 16-17 for the gas engines, while matching the 6.2L's torque output at 460 lb-ft on the 2021-2024 LM2 unit. The 2025 refresh brought the new LZ0 diesel with 305 hp and 495 lb-ft.
Owners on DuramaxForum.com report mixed but generally positive experiences with the earlier LM2 diesel: some describe years of trouble-free ownership, while others cite long cold-crank times traced to bent or warped camshaft position exciter wheels, high-pressure fuel pump replacement ($1,500-$3,000), and DEF system faults that can trigger limp mode if the fluid runs low or gets contaminated. Early production (2021-2022) skews toward more reported issues than 2023-2024 trucks.
The newer LZ0 diesel, introduced for 2025, has drawn its own early attention: reports on GM-focused outlets describe a rattle or knock from the bellhousing area on some 2025-2026 trucks, tied to diagnostic code P06DD and linked to crankshaft end-play and thrust bearing wear. Given how new the LZ0 is on the used market, treat any 2025 diesel Yukon XL as an early-adopter purchase and budget for the possibility of unresolved TSB-level issues.
Forum consensus: The diesel makes the most sense for buyers logging highway-heavy miles who value the fuel savings over the gas V8s. Stick to 2022-2024 LM2 trucks unless you're comfortable being an early adopter of the 2025 LZ0.
Transmission and electrical recalls that apply across engines
Two additional recalls apply regardless of which engine is under the hood. NHTSA campaign 24V797000 (expanded in 2026 under 26V085000) covers a transmission control valve defect on 2022 Yukon and Yukon XL models with the 10-speed and Electronic Transmission Range Select: excessive valve body wear can cause a fluid leak the onboard software doesn't flag, and in the worst case the rear wheels can lock up. The fix is a transmission control module software update that limits the truck to 5th gear and triggers a warning light before wheel lockup can occur. Separately, NHTSA campaign 24V674000 covers 2023-2024 Yukon XLs (among other GM full-size SUVs) where the electronic brake control module's software may fail to warn the driver of a brake fluid leak; the fix is a free OTA or dealer software update.
Trim Levels
| Trim | Key Equipment | What to Pay Extra For |
|---|---|---|
| SLE / SLT (2021-2024), Elevation (2025+) | 5.3L V8, cloth or base leatherette, standard suspension | 4WD if you're outside a warm-climate state |
| AT4 | Standard 4WD, Magnetic Ride Control, 4-corner air ride suspension, skid plates, off-road tuning | The off-road capability is real, but so is the added air suspension maintenance cost below |
| Denali | 6.2L V8 standard, premium interior, 22-inch wheels, extensive active suspension package | The 6.2L's power, if you've verified the connecting rod recall is closed |
| AT4X | 6.2L V8, most aggressive off-road package, unique tuning | Priced at the top of the lineup; verify the same 6.2L recall applies |
SLE and SLT (renamed Elevation for 2025) are the value trims: standard 5.3L V8, no standard air suspension or Magnetic Ride Control, and the most accessible used pricing in the lineup. AT4 adds genuine off-road hardware, but that comes bundled with four-corner air suspension, a known maintenance liability. The compressor alone runs $1,000-$1,200 OEM, and a factory-flawed air inlet hose routing (diagnostic code C1197) is a common, usually low-cost fix (rerouting a pinched hose) rather than a compressor replacement, so don't assume the worst before it's diagnosed. Denali and AT4X both carry the 6.2L V8 and its connecting rod recall as standard equipment, not an option to avoid.
Which Model Years to Target Within This Generation
| Year | Recall Activity | Key Changes | Verdict |
|---|---|---|---|
| 2021 | Launch-year DFM lifter reports; 6.2L recall applies | IRS debut, diesel and 10-speed introduced | Caution |
| 2022 | Transmission control valve recall (24V797000/26V085000); 6.2L recall applies | Same powertrains, early production DFM issues persist | Caution |
| 2023 | 6.2L recall applies; eBCM software recall begins (24V674000) | Denali Ultimate-equivalent packages expand | Good |
| 2024 | 6.2L recall applies (final covered year); eBCM recall applies | Most refined pre-facelift year | Best overall |
| 2025 | Outside 6.2L connecting rod recall's 2021-2024 window | Full refresh: new styling, 16.8-in screen, LZ0 diesel | Good, but priced high and diesel is unproven |
A note on this table before you read it: GMC's own recall filings for the Yukon and Yukon XL are issued jointly, and coverage windows vary by campaign rather than lining up neatly with model years. Don't treat "fewer recalls listed" as proof a given VIN is clean: always run the specific VIN through the recall lookup tool rather than relying on model-year generalizations alone.
2021: Caution. First-year production carries the most-discussed DFM lifter complaints on the Tahoe Yukon Forum, and every 6.2L-equipped 2021 falls inside the connecting rod recall's window. It's also the highest-mileage year on the used market by a wide margin (CarScout shows a mean of roughly 96,000 miles on 2021 listings), which compounds lifter risk on trucks that haven't had preventive work done.
2022: Caution. This is the specific model year targeted by the transmission control valve recall (24V797000/26V085000) in addition to the ongoing 6.2L recall exposure. Forum threads documenting 2022 Denali engine failures and instrument cluster failures are among the most detailed in this generation's history. A 2022 with clean, documented recall completion is fine; a 2022 without that documentation carries more open questions than 2023 or 2024.
2023: Good. Complaint volume and mean mileage both improve versus 2021-2022. The 6.2L recall still applies to every Denali and AT4X from this year, and the eBCM software recall begins covering 2023 trucks, but the overall build quality trend is positive.
2024: Best overall. This is the last model year covered by the 6.2L connecting rod recall, meaning every 2024 Denali or AT4X still needs that inspection verified, but it's also the most refined version of the pre-facelift 5th gen Yukon XL. Lower mean mileage (roughly 40,500 miles per CarScout listings) means less accumulated wear on trucks that haven't had lifter issues yet.
2025: Good, but expensive and diesel is unproven. The 2025 falls outside the 6.2L recall's 2021-2024 coverage window, a genuine plus if you're specifically worried about that defect. But CarScout listings show a 2025 Yukon XL price floor around $55,900, well above the used-buying sweet spot, and the new LZ0 diesel has already generated early reports of bellhousing knock on a small number of trucks. If you want the 2025 refresh's styling and tech without the diesel risk, stick to a gas V8.
Pre-Purchase Inspection Checklist
For every 5th gen Yukon XL
- Run the VIN first. Use CarScout's recall lookup before you see the truck in person. This generation carries several distinct, high-consequence recalls, and completion status is not guaranteed just because a truck is a few years old.
- Start the engine cold and listen. A tick at idle that follows RPM and doesn't fade at operating temperature points to DFM lifter wear on either V8.
- Check the OBD-II port for a DFM/AFM disabler. If one's installed, ask if it stays with the truck. Its absence doesn't mean the lifters have failed, but its presence tells you the previous owner was managing the risk.
- Pull service records for any lifter or engine TSB work. Documentation of past lifter replacement is useful, but understand it doesn't guarantee the root cause was fully addressed.
- Test the transmission for shudder or hesitation under light throttle acceleration between 20-50 mph, and note any harsh or delayed downshifts.
For 6.2L V8 Models (Denali, AT4X)
- Verify recall 25V274000 completion directly with the dealer and ask for closed-recall paperwork, not a verbal confirmation. This is the connecting rod/crankshaft defect and the single highest-stakes item on this checklist.
- Listen for a deep knock distinct from the normal DFM tick. That points toward the rod bearing damage this recall exists to catch.
For 2022 Models Specifically
- Ask about recall 24V797000 / 26V085000 (transmission control valve). Request confirmation the TCM software update has been applied. If the truck has ever displayed a service engine light with reduced power and a transmission stuck in 5th gear, that's the failure mode this recall addresses.
For AT4 (Air Suspension) Models
- Check that the truck sits level. A sagging corner points to a failing air spring or compressor.
- Listen to the compressor cycle at startup. A loud or prolonged cycle suggests the system is working to compensate for a leak.
- Ask whether a "Service Leveling System" message has appeared, and whether diagnostic code C1197 (pinched air inlet hose, a known factory routing flaw) was the cause and fix, versus a full component replacement.
For 2023-2024 Models
- Verify recall 24V674000 completion (electronic brake control module software). Ask whether the OTA update was applied automatically or required a dealer visit.
For Diesel Models
- Time the cold start. Cranking beyond a few seconds on a 2021-2022 truck points to the known camshaft exciter wheel issue.
- Check DEF fluid level and ask about DEF system service history. Low or contaminated DEF is the most common trigger for limp mode.
- On a 2025-2026 LZ0 diesel, listen for a rattle from the bellhousing area and ask directly whether the truck has thrown code P06DD.
Running Costs
| Powertrain | Combined MPG | Key Maintenance Items | Est. Annual Repair Cost |
|---|---|---|---|
| 5.3L V8 | 17 mpg (2WD) | Synthetic oil every 7,500 mi, optional DFM disabler (~$300 one-time), tires | $1,200-$2,500 (higher if lifters fail) |
| 6.2L V8 | 16 mpg (2WD) | Same as 5.3L, plus mandatory recall 25V274000 verification | $1,500-$3,500 (escalates if the recall wasn't completed before purchase) |
| 3.0L Diesel | 23 mpg (2WD) | DEF fluid every ~8,000 mi, diesel-rated oil/filters, HPFP monitoring | $1,500-$3,000 |
Air suspension trucks (AT4, and Denali/AT4X where equipped) add a real long-term line item: a single rear air spring runs around $1,500, and once one corner starts leaking, the others are often not far behind. Factor that into any AT4 purchase even if the system is functioning perfectly at the time of sale.
Frequently Asked Questions
Is the GMC Yukon XL 6.2L V8 reliable? The 6.2L is powerful and well-liked when running correctly, but every 2021-2024 example is covered by NHTSA recall 25V274000 for connecting rod and crankshaft manufacturing defects that can cause engine failure. Verify the recall inspection was completed before buying; a truck that's passed inspection or been repaired is a materially different purchase than one that hasn't.
What year GMC Yukon XL should I avoid? No year in this generation should be bought sight unseen, but 2021 and 2022 carry the most forum-documented DFM lifter cases and the highest average mileage on the used market, and 2022 specifically is the model year targeted by the transmission control valve recall. 2023 and 2024 show fewer complaints and lower average mileage.
What is the GMC Yukon XL connecting rod recall? NHTSA campaign 25V274000 covers roughly 597,630 GM full-size SUVs and trucks, including every 2021-2024 Yukon XL with the 6.2L V8, for connecting rod and crankshaft manufacturing defects that can cause engine damage or complete loss of power while driving. The remedy is a free inspection and, if needed, free engine repair or replacement.
How many miles does a 5th gen Yukon XL last? A Yukon XL with the DFM lifter risk managed and any applicable recalls completed should reach 200,000-plus miles; the T1 platform underneath it is fundamentally durable. The risk factors specific to this generation are the DFM lifters on both V8s, the 6.2L's connecting rod recall, and air suspension components on AT4 and Denali/AT4X trims. Address those proactively rather than reactively.
Is the GMC Yukon XL diesel worth it? For highway-heavy drivers, yes: the 3.0L returns 23 mpg combined versus 16-17 for the gas V8s. Stick to 2022-2024 LM2 diesels with a documented service history; 2021 examples carry more reported cold-start and DEF issues, and the new 2025 LZ0 diesel is still building a track record on the used market.
Bottom Line
Target a 2023 or 2024 Yukon XL SLT or Elevation with the 5.3L V8: post-launch quality issues are mostly resolved, mileage runs lower than 2021-2022 examples, and you avoid the transmission valve recall specific to 2022. If you want the 6.2L's power in a Denali or AT4X, buy 2023 or 2024 and do not skip verifying recall 25V274000 is closed. Run every VIN through a recall check before you commit, and ask specifically about lifter service history on either V8.
