Got my letter last week. Ignoring it for the moment. Pepper has 105 K on her now and runs like a top. I'm more inclined to just replace the pump to the superseded "improved" part... This whole recall has a fishy smell to it. 

 

Like a lifter failure where they replace the offending bank of lifters. Most guys complain about this half measure but my question is, if it is an oil pressure issue that causes the failure and you don't replace the parts that control the pressure that caused the failure is it likely to happen again? I think so.  Replace the VLOM manifold and screens and pump/jets solenoids.

 

Band-Aid on a GSW thinking IMHO.

ok the special coverage is for a faulty vacuum pump which is a mechanical pump attached to the engine. this is not a  recall. the recall is a reprogram of the EBCM software. two separate things. now i

So now we need an extended warranty on the ABS unit to cover premature wear from using it in normal braking?  Seems like yet another band aide to me.  That Corvette electric pump is looking better and

I agree the tune is bandaid. Sounds like it is their fix just so they can say they did there part for the issue. But I will take a new pump.
So far at least more me it says all I get is a the recalibration tune. I have buddies at dealer so they get paid for it so i said fine.

And what is the down side to the recalibration? This ALTERS the original operational parameters for the ABS. If that alteration is better...it would be part of the original flash. Nothing in engineering is free. Right? So what does it take away we don't know about yet? ?

Good question. I will have to ask. I would say it is within the specs of the abs module. Maybe just more agressive settings.
I will know after lunch.

Ya can't take lint out of your pocket and leave MORE. :) 

 

Let us know SPECIFICS please.

The update could also update the threshold for calling out a bad vacuum pump, perhaps catching it prior to catastrophic failure (taking out the master cylinder).

Sure, it would be great to go get a new pump for free. Design problems like this happen, and I believe they have a reasonable remedy.

So what I am told is this.
It was requested of the engineers to find a solution that was cheap,faster and would meet the minimum requirements. As some know power brakes are not mandatory. If they simply recalled all pump(also other parts) the amount of vehicles and cost was far to high and also as I am told moved them to two points. 1. Was the pump defective to the point of liability. 2. What issues legally and cost on the big picture off it all.
I am told they think this "patch" is just good college try and show of "good" PR.
Specs are they looked at the progressive abs and made it fractionally more agressive. When I asked can it handle it and what parts may wear faster for this. They said no idea and we are not positive they are going to test it all out as they would a production vehicle. But that is a different department anyways. Meaning their test truck will be updated.but that doesn't come close to every model and trim with all the climate,uses, and mods people add. So it is possible there is a issue later.
Best question....is it worth getting or not. He said get the new pump have gm pay for it and manually clean out the hard line to the booster if it has oil in it tell me and we will get you the booster,master, and all labor.
That is as far as I can say. Can't share email or doc. So i have my plan. And big brake kit is looking better then ever.

This is the most useful thing I've heard on this site. Great stuff and THANKS!

 

I'm going to buy the pump out of pocket and pay my shop to install it and leave my ABS alone. Should they pay? Yes! BUT brakes are more important to me than getting my way. All I needed was the TRUTH. Thanks for giving me that. Now...that wasn't so hard, was it?

I had the recall done a month ago. The MyChevrolet app still shows I require a recall. Is this my dealer being lazy and not transmitting the service record? Is it the strike delaying updates? How long does it usually take for maintenance history to show up in the app?

OK, promised to check on this for you today and did. It appears my dealership uploaded the info to both my "Onstar" account and my GM maintenance record. Date shown is today 10/24/19. So I have to give credit where credit is due and say they're on the ball.

Great answer and good info but I have a question ......... Just how do we go about having GM pay for a new pump? With recall being as is, I just don't see them agreeing to the new pump. Am I missing something? Thanks.

 

I agree with your assumption here and my guess is they're gambling there won't be later issues, or at least not so many as to make this fix not viable. What do you think?

FYI, good luck getting a vacuum pump if the dealer doesn’t have it in stock. My truck sat at the dealer for 3 days (including outside during the Dallas Tornado event this last weekend but luckily mine was unsacathed) before they informed me they couldn’t get the part any time soon due to the strike. Your mileage may vary, obviously, but bottom line, call the svc department and confirm pump availability first.

Special coverage on this pump has been updated!!! 10 years 150,000 miles.

#N182202780-01: Special Coverage - Brake Assist Decreased Due to Vacuum Loss - (Oct 11, 2019)

 

Release Date: October 2019

Revision: 01

Revision Description: This bulletin is being revised to update the models and extend the coverage period. Please discard all previous copies of bulletin N182202780

 

What We Have Done:General Motors is providing you with the additional special coverage outlined in this letter for the condition described above in the interests of customer satisfaction. If this condition occurs on your 2014 – 2018 model year GM vehicle within 10 years of the date your vehicle was originally placed in service or 150,000 miles (240,000 km), whichever occurs first, the condition will be repaired for you at no charge. Diagnosis or repair for conditions other than the condition described above is not covered under this special coverage program. If you were previously notified regarding this condition, please note that we have expanded the coverage.

Reimbursement:If you have already paid for repairs for the condition described in this letter, please complete the enclosed reimbursement form and present it to your dealer with all required documents. Working with your dealer will expedite your request, however, if this is not convenient, you may mail the completed reimbursement form and all required documents to Reimbursement Department, PO Box 33170, Detroit, MI 48232-5170. The completed form and required documents must be presented to your dealer or received by the Reimbursement Department by November 30, 2020, unless state law specifies a longer reimbursement period.

Just had the recall (reprogram of the BCM) done on my 2014 this past Tuesday, 22nd, 11 days after this revision and no one even mentioned it. Likely they won't as it's much more economically feasible for them to address only those with the severest issues. I'm sure GM is banking on the recall fix to carry most trucks past the 10 yr/150K mile mark.

Got my letter in the mail today. Mine is a 2014 and I am at 109850 miles or so.

I have had a vacuum pump in my basket for about 6 months. I just checked the price on them and they have went up $25 since I put it in my basket. I should have bought the thing and installed it already. Ugh.

Here's my take on the recall and the special coverage on the vacuum pump.

 

The recall is kinda a bandaid so you will have some sort of power assistance to the brakes in the event you have insufficient vacuum to the booster.

 

The special coverage on the vacuum pump shows they acknowledge that they are failing too much! The original letter I received informing me about it said coverage would be extended to 6 years 72k miles. If it fails within the coverage they will replace it, the recall doesn't change that.

 

I'm a technician with the local city fleet and we have access to GM dealer level service info and bulletins. We also have a subscription to the service programming system. I ran my vin the other day and found the special coverage extended earlier this month to 10 years and 150k miles.

 

I did the reprogramming for the recall myself at work and it only took me about 20 minutes. But that only includes setting up the computer and logging into the SPS account to do it. The tech at the dealership will probably spend twice as much time finding your vehicle on the lot, bringing it into the shop, reprogramming, parking, and doing the necessary paperwork to get paid the 0.3 hours (18 minutes) the warranty time the recall bulletin allows for.

 

Warranty work is one of the main reasons I left the dealership almost 15 years ago. It was getting harder and harder to make my flat rate hours match the time I actually spent at work. The other is I was tired of only getting something around $20 a flat rate hour while they were charging something around $130.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
