  • Estimated Cost to Fix: $2,000 - $4,000+
  • Recalls: None Found
• Oil Consumption
  • Description/Symptoms: Excessive oil consumption, blue smoke from the exhaust, check engine light. Issue is most common on the 5.3L engines equipped with AFM.

In summary, the 2011 GMC Yukon has some potential reliability concerns that buyers should be aware of. The most serious issues revolve around the 5.3L V8 engine, specifically the AFM lifter failure and excessive oil consumption. These repairs can be quite costly. Transmission issues, particularly torque converter shudder, are also relatively common. Electrical problems with door locks and the instrument panel can be irritating. Suspension issues are normally not bad unless the vehicle has the autoride option. Overall, potential buyers should have a pre-purchase inspection performed, paying close attention to these potential problem areas.
