2017 Chev 1500 5.3 Drivability issues

Joe1264 · October 25, 2016

I have a 2017 1500 silverado LT with 2000 miles. Truck is miserable to drive. Always feels like there is a engine miss and random transmission shudder. Happens specifically when under light acceleration. Example: 40 miles an hour and light acceleration. You feel shudder in seat of your pants and engine stumbles to accelerate. Also, at a stop, I held brake down(Traction Control was off) and brought RPM's to 1500. Under this load engine missed.

Brought to dealer and they say nothing is wrong with it! Any help is appreciated.

Sounds like cylinder deactivation.....

Try putting it in M5 mode and see if it still does it.

Mine is a 2015 Denali. I have the shudder like running over warning bumps in the road but not as pronounced. I'm taking it in Thursday for a new Torque Converter. I had to wait several weeks for one to show up. I don't know about the low acceleration though, mine runs like a raped ape.

UPDATE:

Picked up the 2017 Chev Silverado today. Been at local dealer all week. Results are pathetic and ridiculous! Drivers side front door excessive wind noise( Have to turn up radio to mask it) Per Chevrolet, nothing wrong with it. Normal and within specs. Shuddering during light acceleration. Stumbles between gears. No power Per Chevrolet, Nothing wrong with it. Within their specs! Clunking and shifting rear end under acceleration and deceleration. Per Chevrolet, Real leaf springs were not torqued (tightened) from factory. Rear drive shaft removed and yoke greased with synthetic grease. Result, still does it. Manager tells me off the record, they are having issues but he cannot do anything as Chevrolet has no fixes. He also tells me that the prblomatic Active Fuel Management system like on my truck is also used on $90,000.00 Corvettes and he is having complaints . They are removing the Transmissions and replacing the Torque converters.Final thoughts: It is a miserable vehicle to drive. I put 40 to 45,000 miles a year on these trucks.Chevy should be ashamed.

How did it work out?

Did you ask to drive another 2017 on the lot to see if it did the same. What you describe sounds just like my 2016

The 8 speed is providing plenty of issues to many people, you are not alone. The symptoms you describe do sound worrisome. I.E it doesn't sound like normal transmission break in period hiccups. And you have 2000 miles already, so you should be through the worst already.

sounds like my 2016. I have the 6 speed and drives like that

How did it work out?

I had the wrong day marked down. I take it in this coming Wednesday. I'll report back when they are done and I've had a chance to test drive it.

I believe there is a bulletin on the 8 speed tranny.maybe a converter problem with no revised converter yet.I have a 16 HD and having same problem but mines a 6 speed

If they plug up there little puter up at most dealerships and it says no codes they have no clue what to do......... part laziness and part ignorance. Do you have another dealer close by that you can take it to? Sometimes though rare you CAN find some intelligent life even at a dealership Good Luck

Here is a little update. I can minimize the wind noise by lowering the drivers front glass just slightly. Again Chevy says this is normal for the wind noise.

Picked up my 15 year old nephew Saturday for his first ride in the truck. Keep in mind he has yet to drive a vehicle and I never said a word to him. As we are going down the road after a few miles he says" Uncle Joe, What is wrong with this truck"? I asked him what he meant, he said" It's jumping and I feel it in the seat". All I could do is laugh and shake my head.

If I put the truck in Tow Mode, some of the drivability issues go away.

Took to my third dealer. They finally listened to me and removed the transmission and torque convertor. As I suspected through 20 years of service experience that was the problem. Torque Convertor was eating itself and pump was failing. Bell Housing was replaced with new pump as comes together. Seem s fine now. Chevrolet would not replace the whole transmission. Just flushed and replaced fluid with new parts. I suspect failure in future.
