2011 Cruze LT Turbo - well maintained - last oil change Dec 2017 at local dealers - only place car maintained and all oil changes there. On hwy and large warning sign and audible - stop car and engine. Out of town GM dealer says oil plug fell out - engine finished - need new one - $5-6,000+. Ouch!!
Servicing dealer refused to accept liability! Am being told over-tightened plug (stripped/cross threaded) or not tightened properly will undoubtedly be the cause - obviously servicing dealer issue and they should accept responsibility and do the "right thing" by repairing!
Anyone know of any other reasons why plug might fall out?
