I assume you put an aftermarket radio in. Did you buy a wire harness made for your vehicle or just cut wires? A lot of cars these days use a bus system that has other wiring tied into it. Before adding an aftermarket radio to modern cars, do a little homework into whether you need a special harness or not.

Issue is more than likely the connection with the bulb

That model had a recall. I hope the dealer did not charge you for it . File a complaint with the division of consumer affairs. Probably won't help since it was probably sold as is. However: anytime there is a manufacturer recall it must be fixed at dealer expense , no matter how old.

Replace the radio with either an aftermarket unit or get a factory replacement at a salvage yard.

Could be the BTSI solenoid in the shifter, have that checked . You may have to buy complete shifter if it proves bad. This would keep you from removing key. Call you local dealer with VIN number and mileage have them check for the recall pertaining to the key rotation, yours may or may not be involved.

It wouldn't be a ground problem If it were the whole instrument cluster would be dead . Checking the BCM an the IPC for DTC'S - diagnostic trouble codes is the proper way to diagnose this type problem . Not worrying about grounds . Odometer The vehicle odometer is calculated and stored electronically in the body control module (BCM) and is sent via the serial data circuit to the instrument panel cluster (IPC) for display. The BCM calculates and stores the mileage based on the vehicle speed serial data information from the PCM/ECM. The IPC displays the season odometer information from the BCM in the driver information center (DIC). The odometer will display error if the IPC detects an invalid odometer data from the BCM. After an invalid odometer data is received from the BCM, the IPC will display the last known odometer reading for 1.5 seconds before error is displayed in the DIC. Speedometer The instrument panel cluster (IPC) displays the vehicle speed based on serial data message from the body control module (BCM). The BCM receives vehicle speed data from the PCM/ECM via the serial data circuit. The speedometer will default to 0 km/h (0 mph) if: • The PCM/ECM detects a malfunction in the vehicle speed sensor circuit. • The BCM detects a loss of serial data communications with the PCM/ECM. • The IPC detects a loss of serial data communications with the BCM. Your best bet would be to take it to the dealer !

Did you check the ground wire for that light? Using your voltmeter, put the positive probe on the battery terminal and your negative lead to the pin/socket that provides ground for the lamp. If you are reading 0 volts, you need to check the ground wire for proper grounding.
