Is Your 2015-2016 Yukon XL 1500 Suddenly Plagued with Issues?
You get in your Yukon XL, turn the key, and… nothing. Or maybe it starts, but it runs rough, hesitates, and the dashboard is lit up like a Christmas tree. If you’re experiencing a frustrating mix of seemingly unrelated problems, the brain of your engineโthe Engine Control Module (ECM)โis often the culprit. As a technician with over two decades of experience under the hood of these GM trucks and SUVs, I’ve seen this exact scenario play out hundreds of times. The ECM is the master controller, and when it starts to fail, it can cause system-wide chaos.
Common Symptoms of a Failing GM ECM
A faulty ECM doesn’t always fail completely at once. It often starts with intermittent issues that can be maddening to diagnose. Look out for:
- โ Check Engine Light that won’t go away, even after clearing codes.
- โ Vehicle randomly stalling or refusing to start.
- โ Noticeable decrease in fuel economy and engine performance.
- โ Harsh or erratic shifting from the automatic transmission.
- โ Multiple communication error codes (U-codes) when scanned.
- โ Other warning lights like ‘Service StabiliTrak’ appearing alongside engine issues.
Expert Pro Tip: Check Your Grounds First!
Before you condemn your ECM, do a simple check. In my shop, I always verify the battery is healthy (above 12.4 volts with the engine off) and that the main engine-to-chassis ground strap is clean and tight. A corroded ground can cause voltage drops that mimic all the symptoms of a bad ECM. It’s a 10-minute check that has saved my customers hundreds of dollars over the years.
