2005 BUICK LESABRE

05 Buick LeSabre, 42,000 miles, 3.8, automatic, check engine, service engine, air bag, traction control u name it all lights were coming on bells were going off, dealer said needed new integrated dash module to the tune of 550. ALso trunk was flying up, trunk ajar light was coming on. Had module replaced, trunk still flying up, so they said I needed new trunk switch module to the tune of 350. Did that but trunk still flying up. Car is at dealer now again, spoke very firmly with service manager this time, they finally found a loose ground wire connection but now are saying that this made the 2 modules go bad. I can see maybe the first one but I feel that while it was in shop with first module they should have found the loose ground connection. Would a loose ground connection cause these modules to go bad? THey have had the car for 2 days this time.

A loose ground connection will NOT cause the modules to go out. It sounds to me like your dealership possibly has an inexperienced individual diagnosing your vehicle. Most people dont understand electronics, so they will tell you things like this to "cover up" a misdiagnosis. You might try a different dealership.P.S. Not all repair facilities operate that way, but there are those very few that will burn you.
