2022 Chevrolet Tahoe: engine knocking or ticking

Filed Oct 21, 2026 · Engine · TX

The dealership diagnosed the truck after investigating a ticking noise and engine misfire. During the inspection, they removed the valve cover and found that one of the pushrods on cylinder #5 was bent. Further disassembly revealed that both lifters on cylinder #5 had failed, causing excessive wear on the camshaft lobe. As a result, the dealership determined that the necessary repair was to replace the camshaft and all 16 lifters. The engine was then cleaned, reassembled, and tested to ensure proper operation. The root cause of the issue appears to have been a failing lifter, which led to damage of the associated valvetrain components.

Vehicle began making loud knocking sound XXX Towed to dealer 9/8 after holiday. They found metal in the oil and believe it needs an engine replacement. A week later I have no answers, there's no loaners available, so I am just without a car. We bought car from Zimbrick Chevy in [XXX]. It was never disclosed to us that the vehicle had an engine replacement right before we purchased. New engine lasted about 16,000 miles. Only once we saw the history of the car in the current dealership's service app did we learn about the engine replacement. This is beyond unacceptable!

2022 Chevy Tahoe went into limp mode at 62,500 miles out of the blue and check engine light came on. At the certified Chevy dealership I was told it was the transmission control valve, Code P2732, which is a known widespread factory issue in these models. Upon further inspection, was told my transmission fluid was completely black and burned and it ruined the transmission and therefore it needs to be replaced. "Consequential Damage Policy: When a control valve body fails and stays "stuck on," it forces maximum line pressure through the system. Continuing to drive under these conditions quickly destroys the internal clutch packs, burns the fluid, and melts down the transmission." This is exactly what happened and my vehicle was never put on a recall list but clearly was a ticking time bomb.

Driving my Tahoe (67,000 miles) down the highway and everything is perfectly fine, suddenly all of the check engine lights began to flash. I wasn’t sure if it was an electrical glitch or not until the engine started knocking loudly. I was on a bridge in traffic and had no where to safely pull over. I had to drive a few miles further just to get to safety at which point the knocking became extremely loud and the entire car began shaking. I had the vehicle towed to the dealership where they informed me the lifters had gone out as well as the cam shaft. Apparently this is a very common occurrence among owners of this vehicle/similar vehicle. I am so grateful this is the one time my two small babies were not with me. It was a very scary situation and I was hours from home. This came completely out of no where without warning. Of course this happened 7,000 miles out of warranty. So now after paying over $70,000 for a vehicle that is barely 3 years old and only driven in town for the majority of that, I was stranded and now going to be out $10,000 to repair.

I’ve done some research on the Chevy Tahoe 6.2L engine failures my Tahoe experienced the same thing our Tahoe just shut off in the middle of rush hour. 2 days ago we’ve started hearing slight knocking on higher RPMs and sometimes just idling and also would have a rough idle but it would go away with no check engine lights or warnings on the dash till today we haven’t taken it to the dealership to look at do to it having 61k miles just past its warranty and us not having the finances to get the truck fixed.

Driving on interstate (I55 - traveling South bound, Bridge over water) traveling at 70 MPH engine started to make loud noise and car was shuttering. We were able to take the immediate next exit. After taking the exit, within minute or two, the car/engine shut off with no way of restarting or steering. The engine did start to smoke when the hood was popped to inspect. Tow truck was called to transport us to the local Chevy dealer in Hammond LA - Ross Downing Chevrolet. Since it was a Saturday, we had to wait for the dealership to reopen on Monday. On Monday, I was called and told that there was indeed complete engine failure, and later in the day it was determined that it was due to a rod bearing issue. GM was contacted since I was 3,000 miles outside of my warranty, and the agreed to cover roughly $17,000 of the repair to completely replace the engine. I was out of pocket $3,227.56. All oil changes and maintenance were on time and kept up with. Just had an oil change roughly a week earlier before the engine failure. There were no lights that came on the dashboard even after the vehicle completely failed.
