2015 Tahoe issues

SS1LE02 · February 6, 2019

I’ve got a 2015 Tahoe LT that I’ve owned for about a year. It now has 110,000 miles on it. The issues I’m having are:

1. The gate sometimes won’t open more than a couple of inches. This is with the fob, button on overhead console, and outside handle. It just started happening the last month. I have read about people having issues when it sits in the direction in life but this is in the middle of winter up here in Minnesota I can be in my garage or outside on a cloudy day.

2. The second row overhead dome light flashes when I hit the brakes or left turn signal sometimes. I’ve also read about this online and was wondering if this is a TSB that the dealer would fix since it’s out of warranty. If not how do I do this cheaply. I got a new light pod from a 2015 that some guy was partying out and it didn’t fix it.

3. Oil leak. Is there an oil cooler on this truck? When I look down at the front of the engine with the hood up, it looks like there is a junction where lines coming out of the radiator come together between the radiator and front of the engine. It looks like it’s fairly wet where these lines meet at a grommet/harness. I first noticed with a small puddle under the truck in my garage. It doesn’t appear wet at the harmonic balancer or oil pan from what I can see. I haven’t jacked up the truck and removed belly pan yet.

I also have a 2015 LT, I had problems 2 and 3 in your post. Have not fixed number 2 yet cause it's been too cold, but the fix is in the front courtesy bulbs. Once these are replaced it should correct the problem. For number 3, the dealer found I needed an extension on my oil filter housing. The leak stopped when they added the extension. I think I commented on these issues somewhere on this forum, could be additional info in the other posts.

So are you actually replacing the little LED bulbs in the second row dome light pod? I open that up and it looks like you have to take them out and solder them in. For the oil leak was there a TSB?
