The valves, pistons, head gaskets are all affected and malfunctioned. They caused burning of the oil and loss of coolant. I took it to the sister dealership of where I purchased it to track the leak and they stated that it was fixed. Upon picking it up and driving it to my home and then right back to the dealership (apprx 12 miles) the truck was making big enought plumes to where it was making other operators pull over or cough. I was following behind the truck to video record and it was producing so much I could not see and had to close my vents to not cough. Our oil said 65 % but decided to check it and there was barely any oil present. Had it towed to the dealership and after picking it up it was only worse than before. This is a safety issue. An emissions issue also. Thank you.

While driving on the highway with my four year old with me the truck jerked and then triggered 3 lights on my dashboard, this made getting to a safe spot uneasy as it was jerking and sounded like it was reving up and down and overall sounded not good. Truck was towed to mechanic and was discovered the lifter failed due to the Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) in that engine model. That failure caused further engine damage to the cam shaft and needs an entire rebuild of the top part of the engine. There were no other indicators that this would happen until it did. I contacted Chevy and they are aware of the situation and offered "cost assistance" only if it was brought to a GM dealership. Given the engine had to be taken apart to figure out what was wrong they said the only way to get assistance was to have the garage put it back together and then tow it there and have their mechanics look at it to determine if they could cover part of it. This isn't a viable option to me seeing how there isn't a guarantee of any assistance and would potentially cost more long term.

I purchased this vehicle after my first 2019 chevrolet silverado trail boss's BCM dealined the vehicle after owning it 32 days. The vehicle with VIN [XXX] has had multiple engine failures causing the vehicle to be deadlined at the dealership for in excess of sixty days. The transmission is now failing as well. I am on my 2nd engine failure issue and the dealership refuses to acknowledge the problem. While under engine failure my vehicle would misfire causing the engine to stall and buck around like a wild horse. The electrical system on this vehicle is a complete catastrophe. The windows refuse to roll up once in the down position more often than not, the tailgate intermittently drops and closes on its own, the notifications on the dash always indicate the tailgate is down even when it is in the upright position, the lane change assist and parking detection intermittently work causing faulty detection when backing in/out of parking and changing lanes on the highway endangering the public, and all while these issues persist the "check engine" light never illuminates. Even when my truck had to be towed into the dealership the check engine light never came on. I have had this vehicle sine 43000 miles and now have 115000 miles and every oil change i have done(I am a shop owner and technician) has had metal shavings in the drained oil that has got past the filter due to the IMPROPER engine repair done by BEAVER CHEVROLET when my engine failed the last time. It is best practice to drain all the oil, remove engine from vehicle and replace the oil pump and pickup after cleaning the engine internally while disassembled to ensure no metal contaminants are inside the engine. Chevrolet simply replaces the broken components and doesn't do the proper procedure when an internal component fails, call any machine shop in any city across america and ask what the procedure is when a camshaft or bearing fails in a motor is. It is 100% not what chevrolet did for me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (

My complaint is regarding faulty oil lines that are known to be defective by GM/Chevy. The oil lines begin to leak in colder weather and according to discussion boards, have even been known to come off completely while at speed and purging all of the oil from the vehicle. This can result in the almost immediate seizure of the engine and loss of control of the vehicle. ? GM/Chevy acknowledges there is a problem with these oil lines by their creation of a Customer Satisfaction Hotline around 2021 instead of doing a full recall. My 2019 chevy silverado 1500 is experiencing the exact same issues with the oil lines as stated by hundreds of other customers. I have contacted both GM and my local dealership and have been turned away advising my 2019 Silverado was not part of the right "build number" associated with the special coverage that they voluntarily created to avoid the full recall of all 2019 and possibly more model years with defective and dangerous oil lines. As reported previously, the oil lines are likely to begin to fail in colder weather which could make for more dangerous conditions should they fail completely and come off of the engine. Although GM states my vehicle is not part of the conditional coverage, my lines began to fail a few weeks ago as my temps dropped well below freezing.

My 2019 Chevrolet Silverado with a 5.3 V8 developed a "tick" in the engine. The truck has 93,000 miles. Subsequently, the check engine light came on. I scheduled an appointment at David Stanley Chevrolet on the south side of Oklahoma City to have it checked. I explained what the issue was in detail because I have a back ground in engine repair. Also, I'd performed research on line looking for "technical service bulletins. What I found was a history of issues with this engine, (5.3), involving lifters sticking. I informed the young lady of what I'd found. I was called the next day and told that the technician could not "replicate" the issue and I could pick up my vehicular. Less than half a mile from the dealer, I tried to merge onto [XXX] when the engine began to shutter and miss. Thank God, I was able to avoid a rear end collation. I immediately returned to the dealer where the the problem was identified as a "stuck #1 lifter resulting in significant damage to the cam. I have subsequently had this vehicle back to the dealer three additional times trying to repair oil leaks resulting from these repairs.

The engine at 108,000 had a lifter that failed. There were no prior warning signs before this happened. This caused the engine to lose power. As a result of the lifter failing this caused other internal damage to the engine. It was towed to a local dealer where I was told it was going to cost over $9000 dollars to repair. It has also had some hard shifting in the transmission as well and many other people have reported engine and transmission issues in these trucks. I had the truck repaired by a reputable shop in my area at the cost of $7000 dollars. It continues to have transmission issues that have not been able to be repaired as of this time.

On January 1, 2025, while driving, I heard a loud bang, after which the engine began to knock. I brought the vehicle to the dealership on January 2, 2025, where I was charged over $4,000 for diagnoses. On January 9, 2025, the dealership informed me that the camshaft had broken. The truck had 130,000 miles on it at the time of the incident. I have consistently had the oil changed every 5,000 miles. In my opinion, this damage occurred prematurely.
