2010MAXIMAVA

Just curious if anyone has heard this or experiencing this themselves.

I have a 2010 Maxima CVT - 39K miles on it.

When i start the car in the morning or sometimes throughout the day. The control panel screen doesn't cut on for about 15 to 20 seconds.

Of course i purchased the extended warranty when i bought the car at 34K miles.

Anyhow, i took it to the dealer and the replaced the control panel. (They thought that would have solved the problem)

I then take it home the same day and it happened again.

So now its back in the shop for the second time and there now going to replace the actual radio itself.

I'm thinking is this just the beginning of something major? Electrical or something. Any thoughts or has someone experienced this themselves?

Also, not to mention; this is the second time i've taken the vehicle into the shop at Sheehy Nissan for an Engine light. The first time, they said it was nothing major. (basically reset it). I then drive to the va beach and it came back on.

So it's now at the shop (as we speak). They said there is a small gasket leak and there replacing. (keep in mind i have the additional warranty; which covers this) My question to you all is? Is there anything else they should look at or fix since the motor basically wide open at this point? I basically don't want to be revisiting this 6 to 12 months down the road.
Thanks
