Welcome to Allpar. Does it seem to be cranking over in the start position fast enough, or is the starter motor slow while cranking?
If you suspect a battery or starter problem, has the starter and wiring been checked? There may be a draw or high resistance.
Once it does start and has a low idle/bogging/hesitation, does that improve as it warms up?
Did the dealer actually have the car act up? It may be best to leave the vehicle the night before so they can diagnose this while it is happening in the morning, otherwise the shotgun approach will probably not fix the problem.
If you have already paid the diagnostic fee and the problem is still there, they should be able to waive any further diagnostic fee for you and get to the root cause (if can act up for them).
There are a number of software flashes availible, depending on when yours was built. Did the dealer update the PCM/TCM controllers?

Vehicle Issue

Hard start, long crank time.;Customer may complain that when the vehicle starts engine runs rough for a few seconds.

System or Component

Engine Misfire,Starting Issues,Hard Start, Long Crank Time;Customer Concern (No DTCs);Group 14 - Fuel System,Fuel Rail,Injectors;Engine Idling;Yes - Intermittent;Fuel Pressure,Fuel Pressure Low,Fuel Quality,Fuel Volume Low,Fuel Injectors,Leaking Injectors,Injector Bleed Down

Recommendation

If there are any codes active in any of the ECUs they should be corrected using TechCONNECT first before continuing. If there are any stored codes in any ECUs document all the Freeze Frame information on the repair order. Stored DTC(s) and Freeze Frame information should be determined if it is symptom related of the customer’s complaint. If there are no DTC(s) stored or active this could be caused by a leaking injector(s). Install a fuel PSI gauge to the fuel system to check the fuel PSI (spec is 58 +or- 5psi) with engine running. The fuel PSI should reach the spec on initial key to run cycle. Fuel pressure bleed down should also be checked when the engine is shut off. Fuel PSI bleed down rate, should not decrease more than 1LB a 1 Minute. If the fuel PSI is not maintaining pull the injector rail with injector tip upside-down and check for fuel pooling in the injector tip(s). If there is fuel pooling in a given injector replace as needed per the TechCONNECT service information. After a repair has been made, retest the vehicle for any codes or issues before releasing the vehicle to customer.

Vehicle Issue

Start and stall. Hard start/long crank. No start.;No start, hard starting after filling fuel tank. Engine would start with throttle assist. Engine runs rough until system clears out. Problem eliminated if purge blocked off. Found faulty purge solenoid. Upon examination of solenoid with cover removed, solenoid traval limit screw was found to be backed out too far. 10mm measurement from base of solenoid to head of screw. Replacement solenoid screw adjustment at 2mm. Replacement of solenoid repaired condition.

System or Component

Die out / Stall,Long Crank During Restart,Runs Poor After Restart,Will not Restart,Starting Issues,Hard Start, Long Crank Time,No Start,Engine Cranks,Start and stall;Customer Concern (No DTCs);Group 18 - Vehicle Performance / Driveability;Starting Vehicle;Yes - Intermittent

Recommendation

Replaced purge solenoid.

Have a battery 'ignition off' draw test done. Something may be draining it. It may be more than that and letting the dealer actually experience the problem is the first step in a correct diagnosis from them. Replacing batteries on a guess is just irresponsible. Testing a discharged battery will not offer valid test result.
The throttle body is electronic control (no throttle cable) and the accelerator pedal position sensor (APPS) does need a relearn after any throttle body or PCM service. It shouldn't need a relearn from a dead battery, unless a glitch somehow occurs.
The latest PCM/TCM software update may help with the bogging/hesitation issue. If the vehicle is under 80,000 miles, this should be covered.

Try to make arrangements to leave the car with them for an overnight and the next day. Give them the time they need to fix it right. They should have no trouble waiving the diagnostic fee as you've already paid that and the vehicle still isn't fixed.
The software updates aren't 'recalls'. They would have to see what part numbers the modules are at and then determine if updates are available.
1.55 amps draw would pull a battery down overnight. This has to be diagnosed and repaired.

Could they be more specific about which connector was at fault and its function? A poor or open connection usually draws 'less' current than it should. If it were causing a module like the BCM not to go to sleep after key-off, that could cause an excessive overnight battery draw.
It may help to speak directly with the technician. Usually the back of the repair order hard copy that goes to the dealer files has the technician's notes on it and sometimes the Service Advisor only gives the customer a generic description of the problem. Ask.

Well still not really enough information to determine either the affected component or the root cause. Is the problem fixed now? If a module stays awake it will draw excessive current overnight while the car sits.
