I Traded a 2018 GMC For My 2024 GMC Sierra And Despite All This Bashing Against GMC Trucks I've Had Zero Trouble With My Truck

I have owned a 01 GMC Sierra 3500 8.1 liter gas engine, since 05. I bought it with 30,000 miles, I have 280,000 miles now. I do regular maintenance and have had no major problems, it's been a great truck. I would definitely recommend GMC trucks. In the past I have owned Fords, Chevy and Dodge trucks , maintenance is key with any of them. Most people just don't do it and complain when something breaks.

I don't own a Sierra or Silverado. I have a 2016 Colorado. I also see alot of negative comments on the Colorados. I see your point with people that don't have problems never posting. I am in afew Facebook Colorado, Canyon clubs and hear mostly positive things. I love my Colorado and I also want to give a big shout out to Millenium Chevy in Nassau Co N.Y. They are the best dealer I ever dealt with. Everyone TAKE CARE. FRANKIE L.I 🛻🛻

New 2012 GMC 5.3 liter SLT All terrain.
88k miles the engine failed due to lifter problems. It was out of warranty and had been dealer serviced. I was losing 2 quart of oil every 5K oil change but dealer said was normal. I ended up paying out of pocket $7500 for a new long block. I will not risk another GM

2005 Silverado 1500 4.8L. - I bought new. 259k miles and running gear has never been touched. Best vehicle by far I have ever owned. It is ready to go anywhere, with no worries. No blowby, no leaks, anywhere. A/c has never been touched. No greasy undercarriage. Tires wear perfectly.

Have a new 2024 chevy 1500 Diesel Great truck love it ! Awesome fuel mileage !

I am on my third GMC Sierra. I loved my 2000 and 2008 but my 2019 is a problem. I only have 54k on it and a cylinder went requiring a complete rebuild since the warranty would not replace it with a new engine. My other two Sierras went well over 150k miles each without any major problems. I have no guarantee that the problem will not resurface and my warranty has expired. I have always loved my trucks but this one has me concerned. Since it was built prior to the pandemic I don't know the reason beyond GMC changing the engine from one that worked to this one that has had many problems. I don't like the constant "upgrades" that are anything but good. I can't afford a new one at this point and just praying it will last.

93 s10 no problems
01 silverado no problems
03 trailblazer minor issues
2010 sierra nightmare electrical issues
2006 escalade blown motor
2019 rst 5.3 lifter failure @63000 loved it up to that point
2024 at4 carbon pro, love it...so far

I stay away from GM, Dodge and Ford.
They have ridiculous problems with engines and tranny issues because they keep changing designs and making them more complicated.
A PLASTIC clip on the engine oil cooling line broke dumping oil all over the ground. A 2019 Silverado Z71 LTZ.
Friggin plastic! Then an idler belt pulley took a crap, 2 months waiting for that
part. Never again!
Bought a 2021 Ridgeline Black Edition.
Zero issues!!!

I guess my 2024 GMC SIERRA with 9273 miles is the only one in the shop with a bad valve body have not seen my truck in over 45 days it's on back order humm

I am one of those affected by the transmission recall. A couple months ago, I purchased a 2020 Silverado 2500HD to pull my camper. three weeks later, my wife and I left for a camping trip. At 65mph, going up an incline, "BANG" the truck jumped as the rear axle seemed to momentarily lock up. A couple of miles later, it did the same thing. This time, the truck lurched about 2' over the center line. Had there been oncoming traffic, someone would have died. My wife was going hysterical, I turned around and nursed us back home with no further events. Literally, two days later, I received the recall email. Apparently, GM put defective Control Valve Bodies that are prone to excessive premature wear, potentially causing what I experienced, in all their 10sp transmissions, even the Allison. This wear can cause it to downshift from 8th gear down to 2nd.

Anyone can give 5-star service when things go as planned. It's when things go sideways that you see the true character of who you're dealing with. GM has failed miserably in this regard.

Armen, here is what you, and the rest of the automotive press, don't seem to be understanding.

GM's proposed "fix" for this issue is nothing but software that will sense the wear and put the truck into limp mode, limiting it to 5th gear, and avoiding the huge downshift. Granted, no one will die (limiting GM's liability), but the truck is basically useless.
As for actually fixing the defective transmission? Well, that's our problem.
In other words, GM will install software (at almost no cost to them) that will force us consumers to pay them for the actual transmission repair.
GM will actually profit from this pseudo-recall.
The story gets even worse when you dig deeper. It turns out that GM started factory installing this software in these trucks in 2022. They knew about the problem back then but continued to sell them as is, rather than going to a different valve body.
These kinds of "screw-the-customer" decisions have nothing to do with Covid. Stop letting them hide behind those excuses.

I am on my 3rd GMC Canton in 10 years ands soon to buy my 4th. Have not had a single problem with any of then.

I have all 4 Chevy Silverado SS Bart at second hand I do all my own maintenance. It's got a 180000 mile running. And the only thing I've ever done is breaks and a battery.
End tires great truck still driving it getting a little rusty now. I live in the rust belt so it's to be expected

My first new GM truck was a 72 Chevrolet. The next ones were a 74, 78, 90, 97, 01, 03, 07, 11, 12, 14, 17, 20 and now a 23. All of them had the 350 or 5.3 engines. Never had a problem with any of them. Just did the regular maintenance and drove them. I will never drive anything else. GM reigns!!!

I own a 2023 GMC Sierra purchased in Dec. 2023 purchased at Paul Sadlon Motors in Barrie, On. At 400 km the shutter started in the transmission, I was told to drive it to 1,500 km as it had to learn my driving habits, so I did. Then at 1,500 km the shutter still persisted so they changed the transmission fluid and added an additive. That worked for one day then shutter returned. I returned it to the dealership and they confirmed the shutter had returned and changed the torque converter and pump. This lasted for 7,900 km and then the shutter returned with a vengeance, so they replaced the transmission. When I picked up my truck there was a vibration and within 80 km on the new transmission the shutter returned. I called the dealership and they said to drive it to 1,500 km so it wou.d program it's self to my driving habits. So I did then took it back to the dealership for the shutter. They confirmed it had returned and blamed it on my tires. Over the next 2,500 km the truck was returned to the dealership for the shutter issue and they kept blaming it on the tires. Again about a month later it was returned to the dealership. They now said they could not replicate the shutter so I went for a test drive with the shop foreman and his laptop hooked up to the truck. During the test drive the shutter occurred on two occasions and the shop foreman acknowledged the shutter. When we returned from our test drive he informed me it was the tires and directed me to my truck. I put new Yokoham tires and rims on my truck and it did not help the shutter in the transmission. It was returned to the dealership again and they again stated there was no issue with the truck and requested I pick it up. I got a call from GM a couple days later informing me that the dealership would no longer provide service to my truck and I was not to contact them. GM has since moved my truck to a different dealership. I guess when a dealships service department is unable to find the fix on Google they discard you as a client. Yes, the dealership told me they could not find how to fix my issue on Google.

I, sadly, have lost all faith in my current 2021 GMC Sierra AT4 with the 6.2L. This was going to be my son's truck in 5 years, but that's changed. I've had the lifters replaced, I'm on my 4th set of motor mounts (I was told they replaced them with the new 2025 ones this latest set), and just recently the CPU just spit out codes which led to replacing spark plugs & wires (two cracked spark plugs were found). Everything has been under warranty until the recent CPU codes. The motor mounts should have been considered a lemon law, but they weren't interested in getting me into a new one even remotely close to my current payments or value from which the issues started. My family has been GMC since I can remember (my wife's grandfather retired from GMC as Vice-President of Programming in Detroit), but GMC doesn't care about loyalty anymore. Unfortunately, it's what we have become for the almighty dollar.

Purchased a new Sierra 1500 crew cab in 2020 . Have had zero issues ,but am concerned with the possible lifter issues. Have had a couple GM mechanics recommend that I eliminate the D.O.D. Is this a good idea ?

Owned string of GMCs starting with '66 Suburban w/305 V6 and 4sp purchased from my Dad on my 16th birthday.

Owned an Expedition, a Land Cruiser, a Hummer H2 and several Range Rovers along side, but my go to daily for the family has been my beloved 4x4 Suburbans and Yukon Denalis (and now AT4) - always purchased on a 4-5 year cycle.

With one exception described below I've simply fueled, lubed and changed the filters on these beasts and have never ever had an issue. And, from 1973 on, every refresh and new platform has been nothing but an improvement.

The exception was my White '21 AT4 Yukon that I waited for with baited breath. I was a little saddened that the 6.2L couldn't be accommodated in AT4 trim, but all the other features (air suspension, electronic diffs, and independent rear) were just too alluring.

3000 miles in, electrical issues emerged (cameras would decide to not work - never resolved - lift gate motors failed) and the Lemon Law clock started. At 15k miles the lifters in the left bank went. At first, dealer and I had no idea what was causing the tapping noise. After a month of endless runarounds, I started to scan the blogs and quickly surmised that GM was staring at a huge exposure for the over 600,000 5.3s delivered with sticky lifters as the production lines fired back up during the pandemic. The initial offer was to rebuild the head and valve train for the left bank only - not acceptable. I'm a lawyer so had little trouble elevating the issue and after using the repaired vehicle without any new problems for an additional 15k miles, GM repurchased the vehicle and built me a '23 AT4 6.2 Silver Metallic according to my spec, including the cat back exhaust upgrade which was good for an additional 20 ponies and an awesome growl). Under the deal, a was dinged for 3,000 miles useage on the '21 and now have the '23 set up the way I had originally wanted. The new vehicle is a joy.

A happy ending!

I bought my 2019 GMC SIERRA DENALI
5.3 brand new currently has 93,000 km
mileage with 0 issues. I just do regular maintenance oil & filter change every 3K.
Changed tires and brakes, rotors once.
Still looking great, just like first time I saw it in the dealership. I love my black Denali.

Doc buys a new GM every five years after the warranty runs out. Sounds like he doesn’t trust them to be reliable after that….
