problem #3

Apr 162024

Sierra 1500 Elevation 5.3L

  • Automatic transmission
  • 50,000 miles


Shake, rattle, ping........service engine light flashes and power loss.

Back from the garage, replaced the right side lifters.......again!

First issue was at 4,500 miles July 2022. That was under warranty and 3 weeks in the shop.

Today, 16 Apr 24.....Out of warranty, out of my pocket. $3,000

It's time for GM to recall!

problem #2

Jul 062022

Sierra 1500 Elevation 5.3L

  • Automatic transmission
  • 4,500 miles

Purchased a new truck so I wouldn't have to worry about fixing it..........NOT.

4,500 miles into this new truck it stalled and had to be flat trailered back to the GMC dealer.

Replaced all the rods/lifters........under warranty.

Now 16 Apr 24, not under warranty and same issue. Just finished paying 3K to have it fixed out of my pocket with 50,000 miles.

Do I start budgeting for this every year?

problem #1

Sierra 1500 Elevation 5.3L

  • Automatic transmission
  • 3,500 miles


Purchased a 2021 GMC 4X4 Elevation on 12/31/2020. Engine stopped running 6/15/2021. Mileage at 3500 miles. Replaced the Right bank of Lifters/Rods. Truck out of service 2 weeks. No Loaner! Still Paid lease cost of $700/month.

On 1/3/2022, 6 months later, engine stops running. Mileage at 7400 miles. Left bank of lifters and rods defective. GMC p[olicy now, replace both banks of lifters/rods. Out of service at least 3 weeks as there is a back order of necessary parts. I am pissed!! I need 4X4 for the Utah Snow with a wife and daughter that need me to transport them every day. I am retired and spent a fortune on the beautiful 5.3 L V8 to last me a long time. Now I am driving an older loaner/rental Chevy Impala LT as GMC will not rent loaner 4X4s to replace mine. Still need to pay the $700/month lease while its in shop by no fault of mine. GM knew about these problems and never warned or advised me before I leased it. I want in on the Class Action Suit for this problem.
