yah, its the way it has been on GD, GE, and GK. not saying it's okay, just saying it's normal on this car. and no it is not a fuel saving "feature". more like an unfortunate characteristic.

I replaced all my interior lights with LEDs. 1/3 the wattage, 5 times the brightness. I've left both maps on all night and started the car up in the morning no problem - but in moderate weather. I don't know how this would go in sub freezing weather.

I believe someone has reported putting in a larger battery without having to get a larger tray. I've observed that my tray is actually bigger than the battery - it only squares up with the battery on 3 sides.

I totally agree. I did the same thing with the same results. As for the battery, I slept in my car one day and accidentally left the headlights on (don't ask). I woke 7 hours later to a totally dead battery. I got a jump and the battery seemed ok for about a month but then started to crank slower and slower. A charger stated that it was fully charged but a load charger rated the battery as only having about 100 cold cranking amps. So I replaced it. Two weeks later, I lost first one then the other high beam/DLR headlights. It seems that the constant charging must have prematurely burned out the elements. In short, once your battery starts to go, don't hesitate on replacing it.

Yes, a larger capacity 51r fits perfectly in the oversize tray. It actually fits better than the original battery.

I'm going to make a note of the 51R on my battery for when I need a replacement.

The 51R battery is
2" longer
1/4" wider
1/8" shorter
than the recommended 151R battery.

Someone approached me to get his battery jumped. He had a 1989 buick electra or something. I left my engine running. We hooked up. I ran my engine at about 2000 rpm and at the same time he started right up.

Have you ever needed a jump? It's a huge relief when someone is available to help. It's late, it's cold, you're late, you knew you needed a new battery. I've needed a lot of jumps over the years so, I try to pay the favor forward. I've easily given out four times as many jumps as I've gotten. When assisting women drivers with a dead battery I have her clip the cables on the batteries. It really helps de-mystify the process for them.

I like communicating information to people but I've found that many people, regardless of sex, appear to not want certain things de-mystified. If you try to de-mystify the sort of thing they don't want de-mystified, they don't try to understand what you have said, get agitated, and may even get angry, and accusatory. If they act this way, I feel like I'm being taken unfair advantage of, if I help them out for free. So I demand payment from them to jump start their car. I only ask for $5.00. Usually, rather than give me $5, they prefer to remain stranded, or call a professional mechanic, wait 45 minutes for them to show up, and give them $50.00. If they are willing to listen, and do some of the work, hook up 2 of the cables, I'll show them where to attach the cable, explain why, and I'll jump their battery for free.

I've found that, these days, young women are just as often as men, if not more often, quite capable of attaching the cables properly, and some older women are quite capable too. For both men and women, I give them one end of the cable set, and see what they do. If they hook the cables up, I'll inspect them to see that they are hooked up correctly, and if so I'll connect the other end to my car. If they ask for help, or do the hookup incorrectly, I'll show them where to clip. If they do nothing and say something like "these things just don't mean much to me" I'll offer to show them where to clip, and explain why. If they don't wan't to listen, I'll demand the $5 to do the hookup myself. I've found that sometimes men act this way. It's not just women.

Which lights are these lights for. Do they fit the front Map lights?
Thanks

Yes, they fit the map light, the overhead light and the cargo light.

You can't leave the interior light on or headlights/marker on -on a 2015+ they automatically shut off. No setting to take this feature away.

I have a 2015 LX. On my car, the map lights do not shut off automatically. On the EX models the map lights look different but I don't know that they work differently. My dome light shuts off automatically only if you have the 3-position switch in the middle position. The other sw positions set it to always on, or always off. The headlights shut off automatically only if you have the switch set to "automatic." In the "headlights on" position they will set off a beeper if you open the driver door while they are on, but they won't switch off. In the "headlights off" position they will usually be off, but will go on, at night, when opening the door and will stay on for little awhile after you leave the car and shut the door, and then they will go off automatically.
