Was buying DEF, The Walmart I went to was out of stock-NONE. Went to Home Depot they had it, Blue DEF-$15, and also Platinum DEF- $21, Is there a difference in Def Fluids? Worth the $ difference? Also, this is 2nd time Walmart sold out, is DEF fluid becoming a shortage item like everything else?  Was not close to the dealer I deal with so I thiought Blue Def is fine? Think I used GM DEF 2 times and Blue DEF 2 times, first time I saw the Platinum DEF, I grabed a 2.5 gals of Blue DEF

Peak claims that 'Platinum' def is 'better' than their regular def and the def of others.

 

Until this new product and new claim I was in the camp that all def is the same.

 

Several posters on dmax sites have reported issues after switching to Platinum, that went away when they switched back.  

At least one poster reported talking to Peak -- who acknowledged there was an issue with some GM trucks, and claimed it was a GM issue.  GM of course insists its's an issue with the 'platinum' version.

 

I'm not interested in trying it. 

It's claim to be better because it 'fixes' a problem that my trucks multiple def trucks have not had.

I'd gladly use the regular version the peak sells -- it would even be on my preferred list -- but I'm not interested in paying extra to be a tester of the 'platinum' version.

It's all the same crap. The chemical formula is the same no matter what bottle you buy.

 

Urea is used at a 32.5 % mixture with 67.5% DI water, that's it.

 

I've run the truck stop DEF fluid for over 164,000 miles in my work truck, never once had a single DEF related failure because of that. We also buy the cheapest jugs of DEF from NAPA as a backup with no problems.

 

DEF is a stable fluid so it can be stored for a super long time. If you want to make your life simple you can buy a spare fuel jug (they sell blue ones) and just go to the local truck stop and pump it full. It's about $4 a gallon here I think. Can buy more gallons for $15 than you can just buying one 2.5 gallon jug from the store.

I bought box of the platinum because the Peak blue was sold out. I promptly received a P2BAA code "SERVICE DEF SYSTEM."  The countdown to limp was activated. The code cleared after a few restarts. Interesting that others have reported issues with the Platinum....will be researching more.

Multiple posters on multiple 'GM' forums have reported problem with the platinum version -- even though the regular peak product has an excellent reputation. 

 

(GM and Peak blame each other for the issues with the platinum version)

No shortage.  Plenty in production.  That store likely didn't order things correctly or someone came and purchased them all for their commercial fleet.  Seen it happen a few times at my Wal-Mart.  They were generally back in stock within a few days or a week.

      Anyone had to replace their Onstar module a.k.a. Telematics unit?

      By davester · Posted

      Hasn't come up in the 3 gm forums I follow. And only gm knows the frequency of failure of that part. LMG, you want a recall so it's replaced for free...

      Transmission Woes :-(

      You need a better code reader/scanner.  You are missing codes.  Did the dealer give you a copy of the SAVI scan from that visit?     If the fluid hasn't been changed, change it.  Shudder will likely go away.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By newdude · Posted

      TLDR to my other post...   Hard. Pass.  Too many what ifs.     Are you set on a 3.0 Duramax?  Have you considered anything not GM just in case?  If you don't have to have a pickup, lots of other options for $27,000 out there.

      I see some red flags.   - No mention in the Carfax if the oil pump belt was changed.  LM2s had a 150,000mi service interval, and its got 164,245mi on it.  So right out the gate it needs about $3000-3500 for that to be done before driving it another 150,000mi.  Belt is at the rear of the engine.     - If something happens to the transmission valve body, the special coverage is expired by mileage.  That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time.   - 2020 LM2s seem to need timing chains after 80,000mi at some point.  They fixed this end of 2020/starting 2021 model year engines.  They will usually set a P0016 I think?  There is another $8000-10,000 if it needs a chain.  The main chain is at the back, secondary at the front so the pump belt would be done at the same time if it needed chains.     - Long oil change intervals.  7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM.  Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all.     - Long fuel filter changes, again likely taking the fuel filter life to 0% or more.  First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi.  So counting its original fuel filter, its had only 4 fuel filters on it.  No bueno IMO.         Good news?    - It has had only two warranty trips to the dealer.  The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax).     - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc.         The "emissions system checked" could just be how something was flagged for Carfax.  GM dealers have to do SAVI reports for warranty repair orders so they scan the truck.  So its possible that is there for that?

      Thank you, @Z45!   NOTE - No all repair shop/Dealers reports to Carfax   That is my main concern.  The CARFAX looks way too clean for a 6 year old anything with 164,245 miles.  Even something known for reliability (like many Toyotas) typically has a lot more replaced, like a Nav screen, interior trim, shock/strut, or brake pads.  And surely the last set of tires (installed at ~58k miles) would be bald unless those were all highway miles.   I'm tempted to pay a local dealer to look up the VIN, but am not sure if that will be worthwhile.  Last time I did this, it was 100% useless, and I felt scammed - they noted the bumper was replaced years ago and that's it.  A 5-year old could spot the accident damage, even though nothing was on the CARFAX.   After giving the dealer a call, the truck may have a hard shift, but they have to verify with their mechanic if that's even a concern.  And I've test driven about a dozen of these now, many near Chicago, and half the trucks shift hard/odd at all throttle positions.  The ones with aftermarket lifts/larger tires shift terrible, and 3 stock trucks shifted so violently I thought the transmission valve body was going out.   At this point I'm conflicted, as I need a vehicle, and am coming up short locally.  Northern trucks in this price range tend to have either multiple owners, a lot of mods (lifts/oversized tires without re-gearing), and are generally in rougher shape.   If this truck showed up in your neighborhood for $27k and you had to purchase it sight-unseen, with the possibility of needing a 10L80 rebuild, torque converter, or rear end - would you do it?  I'm convinced most of the 10L80 trucks I test drove are broken, they can't all shift so bad, with massive flares/slipping/lurching and mis-matched downshifts like a teen driver learning stick.
