I have a 2021 Honda Pilot. Drove it to the store one day and everything seemed fine other than it took a couple attempts to start the car initially. After leaving the store, when I tried to start the car, it would not turn over and displayed several systems errors including:

• Hill Start Assist Problem
• Trailer Stability Assist Problem
• Road Departure Mitigation System Problem
• Brake System Problem
• Auto Engine Idle Stop System Problem
• Anti-Lock Brake System Problem
• Tire Pressure Problem

The vehicle received a software update last week. Also, the turn-over issue was present before the software update. Just an observation.
What can this signify?

 

Need help

 

When trying to start it do you hear a clicking sound? If it's a fast click sound multiple times, it is a voltage issue and if it's one click sound then it is a starter issue.

 

have the battery and alternator tested. with the battery being 5 years old now that's what I would suspect is the issue, but best to check both to be sure
