<3k miles - 3rd time back for service. Seeking thoughts.

[nickbeckss]

Newbie here, love all the helpful posts and DIY posts on this forum.

I'm looking for feedback on what I should do next and at what point to start thinking buyback... it seems like the service department doesn't know what is going on. We've got a new 2017 Yukon SLT 4x4, it'll be back in for service a 3rd time (3 work orders, but I've actually taken it back 4 times and they used an open work order once).

Thus far they have replaced the Fuel Level Sensor and the ECM. According to my SA, GM technical support has been involved... I guess they authorized the ECM replacement. Below is all the history. Vehicle now has 3k miles but at the time this issue first arose it was under 2k miles.

8/29
- Initial CEL
- Scheduled Appt for 9/1 was 1st Available

9/1
- CEL was lit upon drop off
- SA said was off when scanned.
- Techs found nothing wrong
- DTC had code stored
- Picked up on 9/2
- Also identified issue with Homelink intermittent issue and ambient light sensor

9/4
- CEL again lit
- Drove directly to dealership
- SA did not create a new ticket, prior ticket from 9/2 had not been closed yet, he pulled used ticket
- This time code was active
- Fuel level sensor was replaced
- Picked up evening of 9/4

9/16
- Fuel level indicator varying dramatically with tank at approx 7/8 full.
- Indicator showed half, empty, full.
- Refueled, only took 3.6 gallons
- Gauge indicated full

9/17 morning
- CEL illuminated
- Fuel gauge indicated empty but would change while driving

9/17 evening
- Tried remote start via app and fob, remote start failed.
- upon unlocking and starting, rough idle (sounds like misfiring), red oil indicator displayed, fuel empty, lots of warning lights, DIS indicated engine at reduced power
- Turned off and restarted, upon restart seemed to be running fine, except fuel level still incorrect

9/18
- leaving work 5:15pm tried remote start and same issue as before was replicated, rough idle, red oil indicator, half fuel, DIS indicated engine at reduced power
- tried replicating issue after getting home, now remote start worked fine, and CEL no longer illuminated

9/19
- dropped off for service
- DTC's included P0463 (Active) and the following in History P2101, C0242, U0140 U0121, U150F, B127E and P0463
- Per SA, ECM to be replaced, soonest part available would be Friday 9/22, but I could come and pick it up because it is "completely driveable"

9/20
- picked up vehicle in the morning, will return when part arrives.

9/22
- part arrived
- dropped off the vehicle
- SA called at 5:30pm indicating that the programming was failing and that they had ordered another ECM (eta Sat Morning 9/23)

9/23
- Service received second ECM and replaced
- Picked up vehicle at 3:45PM

9/27
- noticed fuel gauge acting funny again, slowly dancing between 7/8 and 1/2 tank.
- Sure enough on the next engine start CEL illuminated, pulled code and found the same P0463 active

I'd lemon it.

 

[Robert Frank]

Sad to say but you have a lemon. Get GM to buy it back!!!

 

[gat0r]

dang, sorry to hear your troubles.

i agree w/ others... GM buy back or get lemon lawyer

 

[cardude2000]

Looks like after 3 years they finally got these rigs dialed in!

Or not

Ouch! That’s no fun on a new vehicle, very sorry to hear about your troubles. Hopefully GM can make it right because that thing is a lemon. These specific issues don’t seem to be common though, at least. I don’t think anyways.

 

[hosseface]

I mean there's just a pretty basic system involving that... If I were the dealer, I'd again replace the fuel level sensor and install a new harness to the PCM and call it a day. Thats a HUGE PITA which is why they are dancing around it.

 

[2011SSVHOE]

sounds like a wiring problem, they are just throwing parts at it..

the remote start will not operate if the CEL is on.

 

[swathdiver]

My service manual says that this is a wiring problem, not a parts problem. For the P0463 code, the problem is in the wiring between the ECM and the Fuel Level Sensor.

Might be time to take it to a new dealership or why not find the most experienced tech in the service bays and ask them to check it out for you? It's worked for me when my new car was in for over a month and they still could not fix it. But once the guy with thirty years experience got hold of it, I had it back in a few days. I bent pin or female receptacle can be a bear to trace, it takes patience and time and someone who can work methodically so as not to miss it.

 

[nickbeckss]

Thanks for all the feedback. It's going back in on Monday, we'll see how that goes.

 

[nickbeckss]

Well the truck spent the week at the service department (dropped off Monday, picked up Friday)... swathdiver you were pretty dead on. Their experienced tech (40+ yrs per the Service Manager) was tasked with tracking down the cause of "excessive voltage drop" that was identified at the fuel level sensor. They traced it back to a connector where the gas tank harness connects into the main body harness near one of the shock towers (service documents indicate: Installed 19119842 : SL-N-WIRE (08965-BOPCK) 19119, Replaced the Harness Connector at X125). Hopefully that's the end of my issues.

Curious if any of you with technical document access have any details on the items and locations of the replacement 19119842, 08965-BOPCK, 19119 or X125??

Also regarding the homelink... they did a test with a J41540 Transceiver Tester and found that module to be bad and also replaced that.

Did they manage to fix this for you, finally?

Nope... check engine light with P0463 code showed back up on Sunday 10/8... I'm working towards buyback but the GM process reminds me of the mortgage underwriting process... between the case worker, service dept mgr, DM of aftersales it's a big game of telephone, document submission, review and waiting.

Thus far the vehicle has been in 4 times, but the service department did the first two on the same repair order... so the latest feedback from my case handler was that from their records it has only been in 3 times. I provided the documentation which clearly showed two repair order close dates, with different notes, but the same repair order number.

Any tips or recommendations from those that have gone thru buyback would be greatly appreciated. Each time I talk to the case manager it seems pointless because all he does is document and forward on to the other players involved (DM of after sales, service manager, etc). I can only imagine what the RVDC step in this process will involve.

The bulk of people I talk to on the road love their 2015 plus Tahoe,Suburban and Yukon..If one parks near me at a rest stop or anywhere else on one my trips from Miami-NYC I always ask them if they have any issues with their vehicle.

Yesterday I was in the Times Square area and asked about 10 Livery drivers who were standing outside their vehicle [2015 plus Suburban and Yukon XL] if they had any complaints about their vehicle..All said no issues.

Last I looked the sales of Tahoe's and Suburban's have not changed since 2011.

With that said I would not buy any used vehicle without seeing EVERY SERVICE RECORD from time of purchase.

1) most livery drivers don’t own their vehicles. They couldn’t give a crap if the thing vibrates a little over 80mph or has to go into the shop. It’s not their responsibility.

I was taking a livery to the airport a while back and the thing boomed and vibrated terribly. I asked the guy if he liked the truck (suburban) and he said it was his favorite in the fleet.

2) same goes for most humans. They either don’t notice or don’t care. A buddy of mine has a Tahoe. Says it’s great. Drove with him and it booms. He’s like “oh yeah that? No biggie it’s a lease”.

That's too bad.

This has been my experience exactly. Been on many where owner says it's great and then after 15min I notice booming, buffeting, vibrations that wouldn't last one day with me.

I've asked people driving '15-'17 Tahoe/Yukon about their experience - they love them. My '15 Denali had trim flying off around the window while I was driving (a known defect according to my service advisor), electronic problems (known defect), left front suspension issue covered by TSB fix (known issue), steering column part replacement to fix the popping sound while driving (known defect).

I don't have the buffeting/vibration b/c I have 20's. There have been transmission replacements 4k to 50k miles on these trucks, roof bars glued down, rear a/c systems fixed, antennas and sunroofs that leak. Shocks, axles, seats... The list goes on for some of these SUV owners. I'm guessing the ones on the road got lucky and love them. Another survey demographic would be the service department lobby where owners are waiting to drop off or pick up their vehicles. Those owners don't have the luxury of driving down the road and loving the $80k SUV they purchased.
