Is Your 2008 Buick Lucerne Running Rough?
If you’re dealing with a frustrating no-start condition, intermittent stalling, a persistent check engine light, or erratic engine behavior, the root cause is often a failing Engine Control Module (ECM). As the brain of your vehicle, when the ECM starts to malfunction, it can create a cascade of problems that are difficult to diagnose. In my 20+ years as a technician, I’ve seen these modules cause everything from poor fuel economy and failed emissions tests to leaving a driver stranded without warning.
From the Shop Floor: A Real-World Scenario
“A customer’s 2008 Lucerne came in last week with these exact symptoms. It would start fine cold, but after 15 minutes of driving, it would stall at stoplights and refuse to restart for half an hour. We scanned it and got a slew of communication loss codes (U-codes) and random sensor faults. After verifying the wiring and power feeds to the ECM, we knew the module itself was failing internally, likely due to heat stress breaking down the processor connections. This is a classic failure mode for these units, especially given their location under the hood.”
