Yukon Engine Failure - Buyback?

[0x_2a]

@jfoj here's the legal blurb, it's a settlement, they refused buyback. I paid $100K for it.... now probably is worth 70s?

I (“Releasor(s)”), on behalf of myself and my assigns, heirs, and executors, in
consideration of $6,500.00 to be paid by General Motors LLC (“GM”), hereby fully release(s) and
discharge(s) GM and its member(s), parents, subsidiaries, affiliates, authorized dealerships, suppliers,
agents, officers, directors, employees, and representatives (collectively, the “Releasees”) of and from any
and all claims, causes of action, demands, damages, fees, costs, and/or expenses of any kind – known or
unknown – directly or indirectly arising from, related to, or in any way associated with the purchase of,
lease of, use of, operation of, service of, maintenance of, repair of, performance of, any warranty for, or
alleged defects in the 2023 GMC (“Subject Vehicle”). If Releasor(s)
initiated any court, arbitration, or other proceeding against Releasees, Releasor(s) will dismiss any such
proceeding, with prejudice, within one week of the execution of this Release of Claims

How many miles now?

Over 30K.

@blanchard7684 Is that on start up or constant?

Constant, always. Loudest at 1700RPM and 2200RPM. Also, the motor runs hot. I'm checking my oil a lot these days, it turns AMSoil Signature Gold black in 2500 miles.

@0x_2a

I cannot believe that GM tried to buy you out of any real remedy even when the vehicle is still likely under the Powertrain Warranty. While I just glanced over the fine print, it looks like if you or anyone actually would accept and cash the check you would likely be SOL even if GM offered a 10 year - 100,000 mile engine Warranty that MAY?? come out of the NHTSA invesitagation. Pretty much similiar language on Insurance Company checks that if you cash the check, the Insurance company is off the hook.

Either GM needs to fix the vehicle or buy it back, they just cannot buy their way out of Warranty Coverage. Even dealer repairs should have some basic 12 month/12,000 Warranty on the work they perform. Hell BMW has a 24 Month Unlimited mileage Warranty on any dealer repairs, or they did at one time if it has changed. Suggest at a minimum to look into Arbitration, really cost you next to nothing, if you do not like the outcome, then you could take further action, but often it might force GM's hand because they would rather repair than Buy Back.

As for the oil getting black in 2500 miles, this sounds like something is cooking the oil. You indicated the engine is running hot, how high?? Do you know the oil pressure or oil temp?

Do you have any Android devices? You could also monitor the oil pressure and oil temp as well with only spending about $45 if you have an Android device.

Would be great to “LS swap” these engines ASAP

 

[jfoj]

Or put 6.6l gas motors in these. Not sure they have the exact same performance, but no DFM and they should be able to easily tune for these chassis easily.

 

[DunzoDenali]

Thanks. How fast were you going when it stopped the second time? (I've only heard of the failure happening at highway speeds.)

Both were at low speeds, traveling sub 25 mph at the time of failure. Very lucky for me. I had been on the interstate earlier that morning.

 

[viven44]

Not sure they have the exact same performance

They are both rated for about the same HP/Torque and the 6.6L does it with the common man's fuel. I'd also guess a HD truck engine like 6.6L really makes more torque on the lower end (and thus horsepower numbers are skewed lower)

And "LS" is just my term for the Chevy engine that was so reliable once. I guess the 6.6L would perhaps be the only "LS" left sadly.

Interesting thread

6.6 Gas L8T Engine Swap in 2015 Suburban

Hello all! My 2015 Suburban is currently dead. 186k miles with a collapsed lifter and a VERY tired transmission. Current plan was to refresh the engine with non-AFM parts, and go back with a GM reman 6l80 transmission. However, I am recently seeing a lot of information about the L8T engine...

Our 2023 Suburban Z71(27000 miles) gave up the ghost on the wife while driving at highway speeds, confirmed needs new engine. It has been at dealership for 45 days so far with no end in sight, no allocation of engines at this time. I tried the GM Customer Care and have been escalated numerous times, inquired about a buyback and that was denied. The area GM Rep is meeting with the dealership GM today, see if we can get any answers or assistance from them. We were not offered a loaner but rather a rental from enterprise and they would only approve a Chevy Malibu. While that may work for some, it does not work when we are carrying more than 5 people (happens most days) pulling trailers, driving off pavement to job sites/ranch. Very frustrating, we have a small fleet of GM trucks for our business and it is making me wnat to go trade them all in for a different brand due to the lack of concern or even answers to timeframes. They all have issues, just ranting!!!!

You should research the vehicle lemon law for your state. Do not rely on GM to help you with a repurchase / replacement vehicle.

If you qualify (based upon your research), contact an attorney that specialities in consumer law. Do not tell the dealer or a GM representative that you are pursuing a repurchase.

My state provides reasonable attorney fees from the manufacturer for consumers that have a lemon-vehicle that qualifies under state law.

I have undergone two new vehicle repurchases from GM - I filed the action myself on one, and won in BBB arbitration and later used an attorney for the second one.

Don’t give up - don’t let GM string you along.

what engine?

 

[Firetrout]

what engine?

6.2

 

[jfoj]

Have lots of questions if you would be willing to answer.

Trying to get an understanding of the engine failures that occur after 7500 miles.

If you would be willing to answer the following questions it would be helpdful.

1. What City/State do you live in? Need this info to understand the climate conditions.
2. Is remote start used often to warm up the engine in the Winter/colder temps?
3. What fuel is typically used, Regular or Premium?
4. Is the vehicle typically used for trips shorter than 30 minutes on a regular basis?
5. Is the Auto Stop/Start typically turned off or currently bypassed?
6. Is the transmission typically run in L9 or is there a DFM bypass installed?
7. Is the vehicle used for towing and/or hauling heavy loads often? If towing, weight?
8. If towing or hauling, are elevation changes greater than 100 Feet or steep grades used?
9. What oil weight are you using? 0W20 or something different?
10. How often is the oil changed? Typical mileage? Per the OLM?
11. Does the engine consume oil? If so, how much between oil changes?
12. Has the low oil light come on often?
13. Are you the primary driver of the vehicle or your spouse?

If you do not want to post this info here, send me a Private Message, I will not share your details. Again, trying to get a profile for engine failures beyond 7500 miles to see if there are common factors. You are not the first and will not be the last failure in the mileage window from 12,000-45,000 miles which seems to be the window of failures beyond 7,500 miles.

 

[Firetrout]

1. What City/State do you live in? Need this info to understand the climate conditions. South Texas/Gulf Coast
2. Is remote start used often to warm up the engine in the Winter/colder temps? remote start used less than 10 times in life of vehicle
3. What fuel is typically used, Regular or Premium? Premium
4. Is the vehicle typically used for trips shorter than 30 minutes on a regular basis? yes other than road trips
5. Is the Auto Stop/Start typically turned off or currently bypassed? no
6. Is the transmission typically run in L9 or is there a DFM bypass installed? no
7. Is the vehicle used for towing and/or hauling heavy loads often? If towing, weight? tow utility trailer less than 5k
8. If towing or hauling, are elevation changes greater than 100 Feet or steep grades used? really flat topo down hear, nothing reaches +100 ft in elevation for a while
9. What oil weight are you using? 0W20 or something different? 0w-20 full synthetic
10. How often is the oil changed? Typical mileage? Per the OLM? 4000-5000miles
11. Does the engine consume oil? If so, how much between oil changes?none
12. Has the low oil light come on often?never
13. Are you the primary driver of the vehicle or your spouse?wife is primary driver unless we are together then i drive most of the time


Hope that covers the questions and helps build your profile to assist others. There was no indication of pending failure previously. Wife had cruise control activated and she stated that it acted like it was in a strong wind or something as it started to decrease speed, she pulled onto the shoulder and then got the message that others have received on the dash. I brought a trialer out to load it onto so we would not have to wait on the side of the highway for a wrecker but I could not get it into nuetral without doing the disconnect down on the transmission. It was at that time I figured its not my problem so dont mess anything else up and let GM handle it. Onstar was called and sent a wrecker that took it to the nearest dealership which is where it has been since.

@Firetrout

Thanks for the info. Not sure I have a specific idea on what happened, but have some thoughts. Not sure you can get any details or were given details from the dealer if the problem was a spun main bearing or spun rod bearing(s) as this seems to be the failure mode most often.

Sounds like you were doing the best you could to maintain the engine. While hard to quatify the short trips less that 30 minutes are tough on these engines because the oil capacity is around 11-12 qts total with the oil cooler and oil lines, so the oil just gets tup to the engine temp by around 30 minutes unless the ambient temps are in the 70-80's+ then you still need about 20 minutes of driving. Fuel dilution of the oil can be a real problem and can be cumulative if the vehicle is not driven for longer periods in between a lot of short trips, especially in the colder weather.

Just not sure where the oil temps end up on the 6.2l when towing. Assume you have pretty hot temps in TX in the Summer as well. I know I have seen 226F for a while on the highway with fuel and only my smiling face in the Yukon. I really question if 0W20 is good for the engine by itself, but when towing I would clearly have a problem with 0W20, just too thin IMHO for the oil temp and bearing loads.

Been running 5W30 in my 6.2l so far, may change it up to 0W40 due to higher oil temps I am seeing with no real load.

If you plan on keeping the vehicle after repairs I can make some suggestions.

 

[LegalBrief]

@Firetrout it may help you to separate the issues
1. You are in a paid rental car, just not one you like, that’s between you and the rental car center manager, they have a lot of latitude, if your kind.
2. Did you buy new or used? Used yourrights are very limited.
3. You are TX, TX has a very specific and short lemon law 24/24 w/ 30 out of service. TX lemon law is run by the state, you may or may not have made the window - you only have 6 months to file a claim (if you haven’t filed do it today) here’s how https://www.txdmv.gov/motorists/consumer-protection/lemon-law
3. You are still covered under Federal law (36/36 or 60/60 (powertrain)

http://www.jtexconsumerlaw.com/V11N3/JCCL_Magnuson.pdf

4. There are specific requirements to file a notice with the manufacturer (asking for buy back on the phone, doesn’t cut it). You need to send a Formal written demand by certified mail, with all service records attached. You need a case number.
5. A buyback is radically different then a lemon law claim. Either process takes an incredibly long time, truck will be fixed ( and you have to pick it up) while the process works forward.

fantastic information thank you...Did you do the oil changes yourself?

We have a fleet account at a local oil change place that we take all our vehicles to. They usually do a very good job and we have never had issues with the work or materials.

We have not taken the rental car, the $44 per day for rental will put you in a GM vehicle like a Chevy Malibu. That does not work going on ranch properties that our suburban travels on. I am driving one of the extra work trucks and my wife is in my truck for now. I greatly appreciate the feedback, I was just adding to commentary of others and hope it can get some information out there to others that may run into the same issues.

There's hope. Let me know if you're up to discuss any specifics. My situation with failure #2 is increasingly sketch and I'm not sure what is next.

$44 rental car can be anything you want, you just need to talk to the rental car manager. Just because it’s a particular value doesn’t mean you get that car or class.

Have you rented a vehicle lately? Last time I rented a Tahoe on a trip, which was a couple years ago now, that Tahoe run me close to $150 a day with all the added tax and fees. $44 bucks a day won’t get you a big full size SUV lol.
