Thur. afternoon I pulled into my garage and put my Cruze into park and the check eng. light came on and the idle became erratic...It was 10 min. to 5 so I drove over to my dealership immediately and pulled into the service door and told the Service Manager what happened and he told me to shut it off (I figured the comp. would retain the code) as they didn't have time to look at it and they would call me tomorrow...They called at 1030, CND the malfunction and couldn't find any codes in the computer (which I don't understand) Because the ck. engine light was on all the to the dealership...BUT they found that the Cooling fan LOW side was inoperative...I always wondered why Chevy made the fan run SO high! I purchased it new from that dealership and it has always run at high speed...I explained this to the Service Manager and he said he would see what he could do as the quote was over 400.00! So he was able to get it down to apx $200.00 plus (with help from GM) The Service Manager mentioned the PCV has been an issue with the 1.4t so I looked it up on this forum and was surprised how many owners have had these issues...WHATS worse is the PCV valve is incorporated into the Valve/Cam Cover! What BAD Engineering! Rather than changing the valve you have to change the whole cover! The PCV failures, Water Pump and Coolant Smell issues must have cost Chevy/GM a fortune! Suggestion, Put Buicks Chief of Quality Control in charge of Chevrolet! The car I traded in for my Cruze was a 1999 Buick Regal 3800, Great car with 200,000 mi and NO issues...My Cruze is a 2012LT with 54,000 mi...Fun to drive, good looking, but all these these recalls/non recall troubles, are just unacceptable...Everything has been under warranty, till now, yet now its starting to come from my pockets, the fan (which I would think would be included in the ENG/DRIVETRAIN Warranty) Not to mention my trunk switch just died, another $60.00... for a 4 year old car!
