2011 Cadillac SRX will not start! Was running fine, parked it and came back out to move it and it wouldn't start. It would turn on at first but not start and then quickly drained the battery completely. Have not had any warning messages or lights and it has been running fine. Help!?!?!

Steve Pack has a good point, but I will take a stab at the answer anyway.

Did you disconnect the battery when you were playing with all the lights? If so, you have to reset the security system and engine immobilizer.

However swapping bulbs to LED seldom works and this is why. Your lights are monitored by the Body Control Module. You know that little light on the dash that tells you that you have a light out, well that comes from the BCM rather than the ECM. Also LED bulbs have an electronic control circuit in them and that sends back signals to the BCM that it doesn't understand. Your high end vehicle is fully computerized and you can't play with electrics, especially adding anything that is connected to ECM or BCM. Your vehicle has a complicated 5 volt computer bus network in it.

Put the bulbs back, see if that fixes it.

If the sensor feels any resistance it will move back, clean the sensors, tracks and or blow with light air.

Normally all parking lights are controlled by the light switch. First turn turn on the parking lights and second turn turns on the head lights.

Are you sure it is not your break lights staying on? if this is your break lights - look at break pedal for break light switch staying on or not adjusted correctly. Does your car battery gets drained from your break lights staying on?

Try jump starting it from another car. or that thing should have a volt gauge while trying to crank it if it drops lower then 11volts it wont start. or if you can hook up a volt gauge to the battery if not just try jump starting it.

Honestly, it sounds more like a shunted starter than a bad alternator. Have both tested.

If you need to jump start, you can use any chassis ground point instead of the negative terminal (recommended to do this in all cases anyway).

Hi Adam

You took the car to the dealer and they cant find anything? Hmmmm
Call GM customer service in Canada or USA tell them what your problem is its a 2011 tell them!!!! make sure you get customer service have your Serial number ready and they will get you to a dealer that will fix it. Make a big complaint and tell them you are going to give this car back to them just atch ans see, I fthey dont cal back again and speak to head manager trouble shooting and complaints of GM.The way they sound they cant find any problems sounds worse than that its a caddi they have dash ,cluster electrical problems you still have warranty its a year and half old :)

The pedal has a little rubber stop on it. When the pedal is all the way off push it just a little and watch the light. If it turns off the little stop is bad. It goes in a small hole where the pedal arm rests against a bracket. Also a broken switch can cause this

Probably a Bluetooth compatibility problem. Just because they paired doesn't mean the drivers in both devices are currently compatible (one of them may have been updated without you knowing). You will have to dig deeper and determine what the current Bluetooth versions are on each and then check compatibility.

The battery might need replaced in your remote.
