  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Several ongoing problems with G90 Ultimate, purchased in Nov 2016:

1. Have to press start button twice to start. First press makes a sound like a partial start. This happens daily, usually when the car hasn't been running recently.

2. Have to shift several times to get into Drive. First few attempts, the shift bounces back to the prior gear (usually Reverse). This happens daily, usually when the car hasn't been running recently. Most often when the car is in Reverse then trying to shift to Drive (e.g., backing out of a parking space, then trying to go forward). Sometimes the shifter gets stuck between gears and I when I nudge it up or down, it drops into gear.

3. Driver's headrest is too far forward. Yes, I know there are various headrest and seat adjustments, but these are not enough to prevent the problem.

My local dealer (Hampton Hyundai) does not acknowledge or know how to fix these problems.

My prior cars were Lexus LS sedans. These kinds of problems rarely showed up in those cars. The few problems that did show up were handled competently by Lexus service. Ongoing G90 service problems may force me back to Lexus.
 
It sounds like a low battery voltage issue. Can you put the battery on a tender and have it charged up to the max the see if the issues come back?
I have an electric vehicle (PHEV) and low 12v battery voltage causes all kinds of issues when it sits for a while.
I'm thinking that these modern cars with multiple computers get finicky when the battery runs low.

Let us know.

Agree or could be a wonky ground connection somewhere. Check your battery cable connections in the trunk and make sure they are good and tight.
 
+1 - ground connection.
If Ok do a battery test after a long "rest".
As a third point: Check for draining sources.
The mentioned symptoms are not usual. Nothing similar in 5 years of G1 + G2 Genesis.
Agree that the dealer should and could do it.
