My 2014 Sierra 5.3L oil pump failed at 90.000 KM/ 56000 Miles.

This should be a recall or class action lawsuit.

Dealer charged $2875.39 CAD for a 14 hours job.I am pissed for sure.

Complained to GM Canada about it on their facebook page and they told me they were happy to know that my truck is already repaired...

Now I affectionately call it my garbage truck.

That's a real ******, were there any potential warnings like oil pressure changes or whining etc?

Yes for sure,that whining sound and P06DD and AFM disabled and remote start not working because of the P06DD...I knew it was coming but its unacceptable for a truck with low mileage like that.My silverado 2004 had 369.000 KM and original oil pump.2014-2018 oil pump are junk for sure.

I have a 2014 gmc that I just bought. the truck has 95,000 miles on it. check engine light came on and it throwing a code that the veins in the oil pump is coming apart. still hold 45 to 50 pounds of oil pressure and I have already changed out the oil pressure switch to eliminate that thought. any body else having this issue. also it was 1.5 quarts low of oil..

My oil pump went on my 5.3L 2014 sierra at ~145k miles. It was throwing P06DD. Had to get new ECM also, ran me about $3500. A few months later the 6 speed trans went, another $3,300.. 2019 was not a great year for the truck.

2015 Sierra 1500 Denali with 80,000 miles and got a low oil pressure light on. Turned the truck off immediately and it towed to GMC where they told me my oil pump blew up, which got into the engine, and now the truck needs a new motor. Regular maintenance has always been completed, so pretty crappy for a $100 oil pump to blow up and wreck the whole vehicle.

Long shot, but when was the truck put into service (sold new date), maybe you are still in the powertrain warranty.

Out of warranty unfortunately

Because of the mileage, and the fact the oil pump's have had known issues, I would open a claim with GM to see if you can pick up any assistance on the repair cost.

Hello fellow truck lovers, 2014 silverado 5.3, 0 oil pressure stop engine immediately, sound familiar? Truck has 124,000 miles, never had any oil pressure codes or low oil pressure, all oil changes and services done at dealer since purchased new, including new tires and even windshield wipers, last oil change was 800 miles ago. Changed pressure sensor and pulled screen under it screen was clean as a whistle still no oil pressure pulled filter started momentarily, nothing there. Removed small oil pan cover from bottom of pan, sump screen is clean but fine, what looks to be aluminum more like dust than shavings in pan. Being that the oil pumps first to the filter then to the motor and the filter should catch anything that might damage the engine top side and there was nothing in the screen below the pressure sensor would I be safe to think there was no damage to engine. I probably haven't ran engine 15 seconds with no oil pressure. Is there any chance that GM will assist with any costs being that it is out of warranty. I can replace the pump myself but if GM will cover anything why wouldn't I let them. The only problem is that they have to do an evaluation before they will commit to any out of warranty assistance and I need to comit to $2000 before a wrench is turned, I was told that it depends alot on customer loyalty. If I do decide to do it myself would it be a good idea to pull a couple of rod caps and see what I see as long as I have them exposed? What are your thoughts on flushing the engine? I did notice a slight belt whine the morning I lost oil pressure so I thought about pulling the vac pump and see what it looks like before I go any further. Any thoughts or recommendations greatly appreciated.
