I have the same problem - it is the central locking controller found under the passenger seat footwell carpet. If water has got into the footwell it will form a pool in the control unit. The connectors will rot after time and perhaps the unit PCB inside the non-waterproof casing may also be damaged. It is not easy to get at this - remove the glovebox and wrench away at the moulded carpet and see if there are signs of damage (especially you are aware of water ingress).

If your car has oil cooling lines, what happens is expanding in heat, no leak, contracting, getting smaller, in cold, seal do not seal properly, and then leaks occur.
Please let me know what you find.

If you take your car in for a 10000 k checkup they will check all fluids, tranny, rear end/front drive, washer, oil, radiator, etc. They will check all hoses and lines(vacuum). They will check all electrical and electronic components. They will check all operational functions, heater, AC, wipers...etc. In the long run it could cost you well into $600-$800 dollars.....that you don't have to spend. If your vehicle is running well and your satisfied with it, than the only thing you have to do is maintain it with an occasional oil change and tune up. Believe me, I've been working on cars, trucks, heavy equipment etc for forty five years. Save your money, especially nowadays and change your oil for 30 bucks, get a tune-up for another 50-100 bucks and keep the rest in your pocket, Thank you, Dana

I would not hesitate to return this car back to the dealer for repairs

Get your diagnostic codes read at an auto store or mechanic and then cleared.
Once you have the codes you should be able to pinpoint the problem and rectify it.
Hope this helps - please post an answer if you need help with the code or solution, Sherwin

if you dont have it you will need to call the dealer.
Or remove the stereo and get the make and model and search online.
Its going to cost if the dealer won't give it to you for free
