Just started getting all of these messages while driving today. Anyone know what this means?

Re: Error warnings
For the yellow "SERV 4WD", the owner's manual says:

"The SERV 4WD light monitors the electric shift 4WD system. If the SERV 4WD light stays on or comes on during driving, it means that the 4WD system is not functioning properly and that service is required."

For the yellow light on the speedo dial:

"This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the ignition switch is turned to the ON/RUN position and may stay on for as long as four seconds. If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock portion of the brake system is not functioning and that service is required. However, the conventional brake system will continue to operate normally if the BRAKE warning light is not on. If the ABS light is on, the brake system should be serviced as soon as possible to restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the ignition switch is turned to the ON/RUN position, have the light inspected by an authorized dealer."

For the upper yellow light on the tach dial:

"Electronic Stability Control (ESC) Activation/Malfunction Indicator Light — If Equipped: The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will come on when the ignition switch is turned to the ON/RUN position. It should go out with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes on continuously with the engine running, a malfunction has been detected in the ESC system. If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected."

For the lower yellow light:

"Electronic Stability Control (ESC) OFF Indicator Light — If Equipped: This light indicates the Electronic Stability Control (ESC) is off."

The "Service Park Assist System" announcement says the rear park assist system is malfunctioning and you should "see your authorized dealer."

My guess is an EVIC (computer) malfunction. Get ye to a dealer.

Re: Error warnings
I have heard of other people having similiar issue, I think it has to do with the TIPM, I believe at least.

Re: Error warnings
There is only 1 solution for this: Bring it to the dealer. Your Jeep is under warranty, let them fix it.

Re: Error warnings
I had the same problem today on a '12 Grand Cherokee with 1600 miles on the odo. Called the customer care# and they said to take it to a dealer. I am a few hundred miles from home, and plan to go to a local dealer tomorrow. The customer care rep opened a case that the dealer can refer to, and supposedly will get prompt service at the dealer. BTW - the indicators went off after 8 or 10 engine restarts.
