My MY2014 Summit V8 is starting to show some issues that have me concerned as I just rolled past the 100K Mark. The navigation doesn't track right, showing me all over the city I'm in and sometime over water. I consistently get the 'service vehicle phone' message. the 3G icon never illumenates anymore. I know I will have to take this to the dealer, just curious if anyone else has experienced this so I can give the dealer the best guidance to fix the problem. Additional the FCW system is constantly telling me unavailable and to wipe the surface (it's clean) and it produces false "BRAKE!" warnings, I've just disabled the system entirely. Anyways, I've got to get this all sorted out - hope I don't need anything replaced.

Everytime I thought a faulty "Brake" light, it turned out I had a brake problem. Not sure on the JGC, many newer cars have separate "Brake" light for the parking brake reminder and the brake problems warning. But in the past the light meant either or.

There used to be a pressure switch in the "H" block that would trip if there was a difference in pressure between the two circuits coming from the Master Cylinder, this would light the brake light, that till that point only came on when while the parking brake was engaged.

With 4 wheel discs they got rid of the "H" block, so those vehicles often have reservoir low switch that trips to warn if the fluid level gets too low in the reservoir. The fluid level drops as the pads are used up, but it won't go below the "LOW" mark even if the pads are totally worn out. So if the fluid drops below that point, you can only have a leak or loss of fluid, so it trips a light to warn. If the level is close to that point, perhaps it sloshing around with braking/accelerating could trip it for a moment here and there.

Hello JS,

If you do decide to get this inspected by the dealer, please let us know. We'd be glad to get this escalated to a Case Specialist and look more into your situation.
