I am curious to know if anyone else just experienced what I have experienced? If so, how did you remediate the problem?

 

I drive a 2019 Chevy Silverado Custom Trail Boss. The Trail Boss edition comes standard with a 3" lift from the dealership.

 

I ended up getting a flat tire on my way to work on the rear passenger side.

 

I thought, no big deal, I'll just use my spare.

 

(When I am at home I have a 2 ton jack that I use, however, I only had the jack provided with the vehicle at the time my tire was going flat.)

 

I was in a level parking lot (work) when I noticed the tire going flat. It was a slow leak.

 

I took out the owner's manual because identifying how to exactly change the tire with the equipment provided with the vehicle can be tricky sometimes.

 

I did exactly as specified in the manual, placing the bottle jack exactly where I was supposed to.

 

I noticed that the bottle jack seemed to be getting near it's maximum height, yet my "flat" tire was barely off of the ground...

 

I did manage to get my flat tire off of the vehicle, however, common sense tells me that there is no way my inflated, full-sized spare was going to clear enough to mount.

 

Assuming the manufacturer would not give me a jack that did not work with my vehicle I continued to lift the vehicle with the jack. Only two turns later and I saw the jack begin to buckle in the middle. I attempted to lower the truck, but it was too late.

 

The jack buckled and my truck fell on to the rear passenger side rotor.

 

My question(s) is:

1. Shouldn't GM provide a jack that is suitable for instructions provided in the owner's manual?

2. Has this happened to anyone else?

3. Who is at fault here?

 

Thoughts?

 

Thanks,

Nick,

So you put the jack under the rear axle? Factory lift wouldn’t affect this. That being said, I’ve never jacked the truck up high enough to pull the tire off with the OEM jack though it most definitely should be able to handle the weight.

Did the jack buckle or did the truck roll forward causing it to fall off the jack?

If it had the GM Accessory lift installed then the kit should have come with a new taller jack. The stock jack should lift the Trailboss just fine but if the accessory lift was installed it sounds like someone may not have replaced the jack with the new one provided in the kit.

My truck was parked with the front tires against a curb and I used chocks on the rear to prevent rolling. However, I was in a flat parking lot. I don't think it was the weight of the truck that buckled the jack. I think that the jack was not designed to lift this vehicle high enough to change a tire.

BPRIKOLA,

 

Yeah, the Trail Boss comes with the lift as is. I drove the truck off the lot with 10 miles on it and did not provide an after market lift. I was assuming that they gave me a jack capable of lifting the vehicle they sold me.

The stock tires on the Trail Boss Custom are just under an inch shorter than the regular Custom (32.08" vs 33"), so your rear axle is actually closer to the ground than a regular Custom.  You certainly don't need a longer jack.  Maybe there was a defect in the jack.

Yeah, I'll post a pic after work. I positioned the jack just inside the shock mount on the rear axle.

Those factory bottle jacks are crap.

As you found, at extension, they're too weak.

Also, the ram end has NOTHING to grip the axle tube or frame with. Try using that thing in the rain.

It's garbage. You can get a small hydraulic jack and pitch that thing in the garbage. This is GM's fault. Not the first person I have heard say this happened to them.

Sounds like OP used the spot the manual suggests.

Rear Position - 1500 Models
5. If the flat tire is on the rear, position the jack under the rear axle about 5 cm (2 in) inboard of the shock absorber bracket.

I’d be pushing for the dealer to replace the jack and to fix any damage. That’s crazy it buckled. Only if the thing rolled is that even possible.

 

I’m assuming you were able to re-jack the truck with the wonky jack to install the spare? I just looked at mine and other than a touch of rust on the jack it looks up to the task. Need to apply some oil to it now!

Mine did okay when I had the same tire go flat. Not the quickest or easiest thing to operate but it seemed solid enough. I do not have the factory lift though.

I agree with you totally but....

Always carry 2x6 pieces for jacking IMO.

Or a 3 ton floor jack [emoji16]

This is incorrect.  The 2" Trailboss lift kit comes with the EXACT same jack as comes in the truck, down to the same part number.  I fully extended the stock jack and the one that came in the lift kit to compare....they both extended the same amount.  

 

As others have posted, you don't need a taller jack for the TB/AT4....the axle is still the same distance from the ground.  The lift blocks are placed between the leaf springs and the axle.  Truck.goes up....axle doesn't move.

    • Follows the motif on the Sierra EV.  Satin finsh to the lower bumper area, painted above:   Elevation       Denali      
    • Not exactly what I was hoping for, but I do like it. I wonder if they'll bring back Smokey Quartz Metallic? 🤔 https://gmauthority.com/blog/2026/06/here-is-the-all-new-2027-gmc-sierra-1500/
    • Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.  
    • New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.
    • No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.
