I found this on Service info and saw some of you already having some check engine lights, here is some info on what it could be,

#08-06-04-035: LNF, Intermittent MIL/SES Light Illuminated, DTCs P0335 and/or P2610 Set (Reprogram Engine Control Module (ECM)) - (Jun 25, 2008)


Subject: LNF, Intermittent MIL/SES Light Illuminated, DTCs P0335 and/or P2610 Set (Reprogram Engine Control Module (ECM))


Models: 2008 Chevrolet Cobalt SS

2008 Pontiac Solstice GXP

2008 Saturn SKY Redline

2008 Opel GT

2008 Daewoo G2X

with ECOTEC® 2.0L I-4 VVT DI Turbocharged Engine (VIN X -- RPO LNF)




--------------------------------------------------------------------------------

Condition
Some customers may comment on a intermittent Malfunction Indicator Lamp (MIL)/Service Engine Soon (SES) light illuminated with no engine performance concerns. Upon inspection, one or more of the following Diagnostic Trouble Codes (DTCs) will be stored in the ECM:

• DTC P0335: Crankshaft Position (CKP) Sensor Circuit

• DTC P2610: Control Module Ignition OFF Timer Performance

Correction
If routine diagnosis using SI does not reveal any obvious cause, DO NOT replace the crankshaft sensor for DTC P0335 or replace the ECM for DTC P2610. Reprogram the ECM using the latest calibration if the above concern is encountered. A revised engine calibration has been developed to address these issues. Reprogram the ECM with an updated software

 

Damn...you mean there's a Daewoo with this engine in it somewhere?

edit: Well, I'll be damned...

 

My thoughts exactly.

 

I would have given odds in a bar bet(-%
