What the data shows
This Yukon Denali offers a lot of capability for $10k, but it's at a mileage where expensive repairs are likely. If the seller has records of transmission service and AFM work (or you're prepared for it), it's a decent consider. Budget about $7,800k–$5k over the first year for potential lifter or transmission fixes.

Detailed findings, 10 items
Click any card for the full breakdown, repair cost, and what to check. Items already handled by the owner show as checked.
Reflects the open findings; items the owner handled are excluded.
Confirm these before you buy. If you or a mechanic can verify them, that clears the car instead of ruling it out.
AFM Lifter Failure
Active Fuel Management lifters can collapse, causing misfire, rough running, and potentially camshaft damage. Extremely common on the 6.2L L9H at 90k–140k miles.
Transmission Shudder & Failure
The 6L80 6-speed automatic is prone to torque converter shudder and internal failure, especially after 100k miles. Symptoms include vibration at highway speeds, delayed shifts, or hard engagement.
Costly repairs, but not urgent to verify before you buy. Price them out and use them to negotiate.
Oil Consumption from AFM
The AFM system can cause excessive oil consumption — many owners report burning a quart every 1,000–2,000 miles post-100k. This is a nuisance and can lead to low oil pressure and engine damage if not monitored.
Fuel Pump Module Failure
Fuel pump modules on GMT900 SUVs are known to fail, especially in high-mileage examples. Symptoms: difficulty starting, stalling, no start.
Minor wear typical for the car’s age. Not worth negotiating over, but good to track as an owner.
Power Steering Pump Whine
Power steering pumps on these trucks often develop a whine at low speed or full lock, especially when cold. It's usually not failure, but can indicate low fluid or impending pump wear.
Dashboard Cracking
The dashboard on 2007–2014 GM trucks is prone to cracking, especially in sun-exposed areas. Many live with it.
Brake Vacuum Pump Recall (NHTSA 15V-240)
GM recalled certain 2010–2014 models for brake vacuum pump failure, which can lead to reduced brake assist and longer stopping distances. Although recalled, some trucks may not have been fixed.
Heated Seat Failure
Driver's side heated seat often stops working due to broken heating element or control module. Common on these trucks after 100k miles.
Verify: Recent Transmission Service
At 142k miles, the 6L80 should have had fluid and filter changes at 100k. If not, it's overdue. Some shops recommend fluid exchange every 50k.
Engine Discrepancy: Listed L96 vs 6.2L L9H
The input lists engine code L96 (a 6.0L) but trim is Denali with 6.2L. This is likely a data entry error. Verify actual engine and ensure it's the 6.2L L9H (or L92). Mix-up could affect parts and performance expectations.
What's working well
Good: 4WD with Auto Transfer Case
The 4WD system on these trucks is generally reliable. At 142k miles, if serviced (transfer case fluid changes every 50k), it should work well. Good for Boise winters.
Adds utility and resale appeal; no common failure points if maintained.
Good: Price Matches Market
You're not overpaying if the mechanical condition is solid.
Reduces risk of negative equity if major repairs are needed.

Critical and major items to confirm first.
Possible year-one expense
Caution items with repair-cost context.
Each range is what that one item costs if it turns out to be present. Not every item will apply to this car, so they do not add up to a bill. Verify with a mechanic.
Asking is $10,000 against a typical $10,000 for this car and mileage. The work is the difference, not the sticker.
Negotiate your offer
Asking is roughly in line with the market estimate. The documented repairs below are common points buyers raise.
- Documented critical/major repairs of $5,600–$9,900 you can point to.
- Strongest items to raise first: Transmission Shudder & Failure, AFM Lifter Failure.
Pricing is in beta. The market estimate comes from research models and can be off by thousands on the same car, so check recent local listings before you rely on it. This is information to help you research, not a professional inspection, an appraisal, or financial advice.

In-person inspection
10 things to check before you buy
2 major and 5 caution findings, turned into a walkthrough for the driveway. Answers save as you go.
Before you leave: Ask the seller not to start or move the car before you arrive. A sales-ready car has usually been warmed up, and a warm engine hides the startup smoke, rattles and rough idle that the first section is built around.
Everything on this list is what you can see standing next to the car. A shop on a lift sees the rest, and a written pre-purchase inspection listing parts and labor is what a seller has to answer to. Budget roughly $100 to $150 at an ASE-certified shop.
