I had this issue happen a few times but I'm almost to 120K miles.  What are the odds they extend it past 72K miles?

Call my dealer today, to inquire about the extended service period. They referred me to GM. I called GM and they referred me back to the dealer. I hope this isn't a series of run around.

If you deactivate AFM and tune for it then that's probably possible, but a better route is to use the electric vacuum pump like the Vettes have. The thoughts behind implementing the vacuum pump was du

Just had my pump replaced free by Chevy.  

Were you having problems or experiencing hard braking?

My 2014 Sierra has done this for a while. I first noticed it backing my boat down the launch. I had to use both feet to get it to stop. I thought it was just wet brake but it’s happened more than once. Happened last night backing into a parking spot that had a downward slope. I’ll be calling the dealer Monday.

are you beyond 72k miles?

Just noticed the same thing last weekend when I backed a Parker down a ramp.  Put my foot on the brakes and didn't slow down.  I thought the truck was getting launched at the same time.  How pathetic is it that you cannot stop a boat rated just over 60% of the max trailering weight?

Yes after initially stopping completely then rolling up and stopping one or two more times without much or any throttle input the brake pedal would build up and be hard to push offering very little assist.  Now after the replacement of my vacuum pump those third and forth brake applies feel more like the first and second.

Should be 100K if you ask me.

This will leave many owners out in the dust that are beyond 72K

 

So does this coverage automatically cover replacement of the vacuum pump or only if you report a problem and they "replicate" the problem?

I already talked to our dealership (I have been complaining about this since 2015).  Kept getting brushed off, that there is no recalls.  Now, I am over the mileage, and dealership says "sorry".....I have escalated to GM customer service.  Fingers crossed that they will do something....especially since I have been questioning the brakes for so long.  And......we have had one tiny fender bender, because the truck didn't stop, when backing into a parking spot.....and the big one.....hubby was driving through a round a bout, and tried to stop for oncoming traffic and couldn't.  Frigg

Don't forget about the emergency brake.

I made appointment to get this fixed Friday.  I'll be over 122k by then.  I hope it's under $1K.

Received my notice in the mail yesterday - it states "failure to follow recommended oil change intervals could contribute to this condition." I can already hear the excuses for a sub-par part failure being blamed on oil change recommendations between manufacturer (oil) and DIC.......Too - I do not have the DTC set as of yet however, the condition is present.

 

I have some time before this "fix" runs out - so I will let the garage monkeys figure out the technique before I get in line to change out mine

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
