2008 cts sunroof wind noise


Hi Gary,

Apparently there has been some 'alignment' issues with the sunroofs coming out of Cadillac. As noted in the attached thread, the dealer can perform an adjustment which eliminates (reduces) the windnoise.

Hazard lights stay on even when car off on a 08


You have to manually stop the hazards with the switch. It doesn't matter if the keys are in it or not. That's normal.

Is it ok to drive 08 cts with p0008 code


I think code numbers will start at P0100-P0800ish. Higher code numbers are the vehicle specific. Not saying its impossible but but I never say a code list go bellow P0100. Maybe check your code again.

The car cranks fine (good battery) but will not


Hey all. I've had my 2003 in twice for the Crankshaft position sensor. In Feb 08 it fixed everything. My car wouldn't start when it had been running for a while. I'd pull into a gas station, then go to start it again and it would just turn over. Same thing just happened in July 2010. They replaced the crankshaft position sensor again, but now it's still doing the same thing. If I let the car sit for 20-25 minutes, it will start and run just fine. However, this time around the check engine light is on and it has never come on. I'm open to any suggestions as to what to try next. What is the PCM exactly?

Burning rubber smell inside car-2003 CTS Cadillac


Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL
