My Suburban 2015 LTZ's issues

Suburban2015 · October 16, 2014

I received my Suburban 2015 LTZ Black in March. I found it interesting reading the various issues as it looked like I wrote some of them.

Mine are as follows:

1. USB ports do not have enough amps to charge any current smartphone such as a Samsung Note 3 or Note 4. It will keep it power but it will not "charge" it. So using USB to charge is useless. One either has to use the cig lighter or the 110 plug which is what I use to "charge" it.

2. I read about the trunk popping issue. Interestingly this occurred within a few days of me using it. It happened only one time and has never happened again. Maybe good luck and it fixed itself... I live in South Florida with hot sun!

3. I just started noticing my drivers seat wiggle when turning or going over bumps. Kinda freaky...

4. I have an ongoing annoying rattle in the passenger driver's side door speaker.

5. Had a one time occurrence of an error message displaying on my center console saying "Service Front Camera". I took a photo of it and took it to a local dealer who couldn't explain it and reported it. Funny that the Suburban has no front camera.

6, Tunnel noise sound with windows up. This is an ongoing issue.

7. Sometimes it has great pickup power from a standstill and sometimes it seems like it is a problem and slow with the gears. Anyone have this?

From my experience, the problem when you report an issue for a brand new product is the dealer service techs have no clue and when one goes fishing for the problems, they create more problems. So it's like you want everything to be working as perfect for a $65K+ SUV but at what price and time of constantly bringing it in...

Is it possible #7 can be fuel related? I know my 2013 acts differently depending on where I get my gas.

---It does ... if you have lane departure warning, you have a front camera.

I actually use Super all the time. I assume it is possible...

Interesting..but they aren't actually video cameras that display like the backup camera then.

No it doesn't display video...it "sees" lane markings, dividers, road edges, etc.

Anon2015 · October 19, 2014

....aren't you just a little bit concerned the dealer didn't know you had a front camera?

Suburban2015 · October 24, 2014

Concerned not really as I know the dealer is horrible and even though they are 10 miles from me I now will go 60 miles to another dealer. I will never go back to a non run properly business.

Turn off the traction control and take off. The truck holds itself back with it on. Its a totally different animal with it off

Does your happen to be black? I had to have my rear spoiler replaced b/c it would heat up and not allow the back hatch to open. Just curious on the color, that is all I've seen have the issue on boards.

3. I just started noticing my drivers seat wiggle when turning or going over bumps. Kinda freaky...

Mine does this and it is annoying. Taken it in twice and they keep saying they can't duplicate it. It's about to go back for a 3rd time and I will not pick it up until it's fixed.

4. I have an ongoing annoying rattle in the passenger driver's side door speaker.

I had a horrible rattle coming from the rear passenger side due to an issue with the jack that is inside the wall. Once they replaced some part, it went away.

7. Sometimes it has great pickup power from a standstill and sometimes it seems like it is a problem and slow with the gears. Anyone have this?

I use to have a problem when I'd turn at a stop light from a stop. Once they did some technical service bulletin fix, it went away.

It's sad that we spent over $60k on this and we have so many issues already. It's been 6 months for me and I don't know how much longer we will continue to deal with it until we decide enough is enough and take the hit on it.

I would like to hear more about the "tunnel sound noise" you are experiencing. Did your dealer try anything to solve it?

I just picked up a 2015.5 Denali XL and as soon as I drove it home I noticed a resonance noise that drives my ears crazy. Its a low frequency "drumming" noise that is there at most speeds but gets really noticeable around the 68-75 mph. At its worst it can almost feel to my ears like the buffeting when a rear window is left open. I took it to the dealer and they agree its not like it should be but have no idea what it could be, so they are going to contact GM to see if they know. I test drove a 2015 Yukon XL SLE to see how that one sounds and it was every bit as bad. So I am curious if anyone else is experiencing the same thing?

carz24 - visit the "2015 Yukon Noise In Cabin" thread, be prepared. You say you have a 2015.5 model, folks on that thread would like to hear from you

They replaced the front drivers seat bottom frame on my 2015 suburban and it fixed the seat movement issue.

I have no input on most of the issues, but on the USB port ones, are you using your OEM Samsung USB cable? Some aftermarket cables draw more power than the phone actually needs.

Reason I ask is because I rented a 2015 Tahoe for a few days and it charged both my iPhone 6 Plus and my friend's Note 3 without any issues.

Other than that, good luck with your SUV. It is indeed sad that a vehicle this expensive has so many small issues with it so early in its life.

I have an issue with my brakes on my 2015 suburban LTZ.

In March 2015 I got a DTC message service brakes assist. Dealer checked and reported no issues found. Mileage at that time 7956. From then till now had the brakes checked due to crunching noise from wheel area while braking. Dealer unable to duplicate. On 2/24/16 while driving in traffic in NYC suddenly the brake peddal felt like a brick and the truck was difficult to bring to a stop. Thank god it stopped without incident. Took it to dealer and its the Vaccum pump., Truck just exited warranty 25 days ago dealer says I have to pay for repairs even though they have changed on about 4 other Suburbans and GM has replaced the original pump due to failure on other suburbans.

Anyone else with this problem?
