You may find helpful diagnostic fault codes stored in the TIPM, cluster (CCN) and driver/passenger door modules (DDM/PDM). You might need a special code reader to access these; like the StarScan/StarMobile/WiTech (or equivalent).
The pulsing odometer display sounds a lot like a poor ground or power connection to the cluster. A poor connection can leave a module turned on and discharge the battery. Any underdash or underhood work done to install the Remote Start should be checked over carefully. I have seen some real aftermarket accessory hack/splice wiring jobs. Any aftermarket security/alarm system?
If you do take it to a dealer, have them update the software in all the modules to the latest and greatest versions. I can check later for any TSB's or STAR case histories relating to these issues.
