Starter button lag

[Elton45]

On a few occasions I've pressed the starter button ( held it) without the car starting. There's a lag of 10-20 seconds. I've had the 2013 Genesis Sedan just over three weeks and this happened four times. Seemed like a seat belt interlock twice as car started after I fastened the belt

Any suggestions?

If the brake pedal isn't pushed, pressing and holding the start button for ten plus seconds will cause it to start anyway. Maybe you aren't pressing the brake pedal hard enough, or your brake light switch is failing?

Ok..noticed that I had electronic holding brake on .And also two fobs..wife's and mine in the car.
Could either of those factor in?
TIA

No, neither should be a problem.

Put over 100k on my '15 - foot on brake, press and hold start button for ~1 second and release. There were a couple times where it started a second or so after I released the button - but that was the worst I'd ever seen it do. Don't let off the brake until it starts.

Checked the fob 2.89 vdc
Im guessing it shouldn't be 3.0??

Yes, depending on temperature though. You should probably replace the batteries in the smart keys, but I don't think that will resolve your current problem.

Well I replaced the batteries in both fobs I also checked the battery and the charging system. Both are good. Battery was 12.64v at rest charging @14.35 at idle.
Dealer(Kia) tech "looked at it"
And gave me the word about stepping on the brake;also that it sometimes had to check the system before it would actually connect and start(huh?)
I was following up on another tip to check the ground cable from the battery to the frame(it was fine,tight, no corrosion) when I noticed what I thought was water on this battery and a little bit on the floor of the trunk.
Since I couldn't find any place where water would have leaked in and the battery actually looked like it was sweating. I'm guessing that it may have been overcharged.
Could this be the source of the problem? Any thoughts.

Techs at Kia and Hyundai said rf interference could explain this. They both mentioned my cellphone location in relation to the fob.
Over the period of the last couple of weeks, I acted on suspicions and had my wife leave her Genesis fob at home. For the most that worked. There still was the occasional time there was a lag. Then I noticed she had the fob for her Chrysler 200 in her purse. Left that out of car and so far the car starts every time..going on 10 to 15 times.

Well I think I may have resolved the mystery.
The lagging starter button continued occasionally ever since April. Usually 2 or 3 attempts would finally work.
In the past week it had gotten worse much worse. I was having to try 3 or 4 times.
Finally got to work on it today and started by checking the battery. It was 12.35 which is low so I put it on a 10a charger which registered only 60 % charge. In less than an hour it was fully charged.
Since that time, it has been started stopped and restarted about 5 times all on the first short push of the button. So I'm checking out a new battery. But I think the solution may simply be keeping the thing fully charged. The alternator is putting out 14.6, so that's not the problem.
I'm told the premium antique packages that I have are both powerhogs and just difficult to keep a full charge especially with short trips and frequent starts
Hopefully, this helps some of you out there who've encountered similar problems problems.

How old is the battery? You car is about 13 years so could be end of life for the third one, even the 4th depending on conditions.

I have no idea. Suspect 3 to 4 yrs old. Going to run a load test tomorrow and go from there

Well, you called it right! I couldn't see the date on the battery at all and checked the brand= ceased production in 2019! So at least 5 yrs old.
Rechecked the battery and charging they were OK.
Three days later Car died and left me stranded. I had a towed back to my house And recheck the battery and the charging system.They were all reading fine. The car still would not start. But when I doubled back to check resting charge it was only 12.3.
I finally broke down and had a toad to the dealers bottom line. Weak battery replaced dead starter motor replaced.
Starting at the push of a button now. Techs speculated the weak battery could have hastened the starter demise OR vice-versa. Although average life span of starter on the 3.8 is right around 120,000 miles I'm at 122,000.
Lessons learned...shell out the $250-300 for a new battery, if there's any doubt as to it's health. I I would have avoided months worth of frustration as it deteriorated and maybe avoid an expensive repair.

An expensive but happy ending.
