SUSPENSION
I went to dealer for an oil change last week. They told me the left front shock had a minor leak and they would be ordering me a new one. After arriving home I noticed that the passenger side shock was also leaking. On 11/28/23 the truck went to the dealer to get both front shocks replaced. Upon arriving home after the new ones were installed I looked at the shocks and noticed the passenger side was leaking fluid to the point it was puddling in my driveway. The fluid was pissing out from inside the shock. I began taking photos and videos of such. My wife is 22 weeks pregnant and this was in needed stress for her. Not only did the brand new shock fail but put her and my future baby at risk.

ENGINE
On October 2, 2023, the check engine light starting flashing and loss of power while driving. I was not far from the dealership where I purchased the truck on September 12, 2023, with 29.000 miles. They did diagnostics on it and found that the engine/powertrain computer/module needed factory reset. Then on October 17, 2023, I started my truck and heard what sounded like a knocking sound in the engine. It quit after about 1 minute during cold start. The next day it sound got worse, so I drove it into the dealership to have them look at it. There were no warning lights or any other warning signs. Was told by the service advisor after showing them the video I took of the noise that the lifters have failed. The repair was done a week later and that did not fix the issue. I was told the truck needed a full engine replacement. I'm very fortunate that I was not driving at the time when this failure happened, or I could have had an accident. It is now almost a month later and I'm still waiting on the engine to arrive for replacement.

POWER TRAIN
On 6.22.23 at Lake Powell AZ this truck transmission locked up twice and nearly threw the wife and I through the windshield, very traumatic!! Happened towing a boat entering highway, had to pull to a narrow shoulder. Jarred our bodies, seatbelt into shoulder/chest. The engine light came on, had truck towed to Flagstaff Chevrolet. Had it 3 weeks. Drove home to Huntington Beach, CA without issue. Drove fine until 10.21.23 when engine light came on. Took truck to Delillo Chevrolet on 10.30.23 where purchased, they diagnosed, said Flagstaff Chevy did not program trans. computer correctly, programmed and said it was good to go. Picked up truck on 10.30.23, drove about 50 miles 11.2.23 to work and back, that night went to drive and the engine light was back on. I turned off an hour later. I drove it the next day no engine light, leaving physical therapy for my recent shoulder replacement, going 40 mph when it did the same thing it did in June! It jolted me two times nearly hitting my head on the steering wheel. The transmission shifted to 1st gear, certainly red-lining the engine. I drove the truck slowly to Delillo, just a few miles away. I told the service manager I can never drive this truck again, it is unsafe, traumatizing waiting for this to happen again. I would never put my family in this truck again. It has caused me physical and emotional trauma. The vehicle is unsafe, the jolts caused my new shoulder to hurt. It is devastating to think what would happen if I was at freeway speeds. Others need to know about this issue as well. Thank you so much for your time and what you do to ensure the safety of vehicles on the road.

On October 31st while driving my vehicle my power steering light came on stating ESC POWER STEERING Failure/Issue. This caused me to have no power steering. I was able to safely stop the vehicle. I restarted it numerous times with the same message showing up. About 5-10 minutes later it started with no issues and without the same power steering message. This is extremely dangerous!

Push start button malfunctioned. The vehicle would not turn off last night and took about 30 minutes to get vehicle to turn off. Next day, had the same issue where vehicle would not start and left me stranded. After calling for a tow truck, I was able to start the vehicle. When researching the problem online, I saw several other complaints of the same issue where the buttons malfunctioned and could either not start their vehicle or turn the vehicle off.

rear third brake light is leaking water into the cab and causing water stains on the headliner. I am worried about it eventually causing an electrical short or more water damage. I don't have a rear window that slides open and the rear glass has never been replaced nor has the third brake light all original from factory.

POWER TRAIN
When I shift the vehicle to park and turn it off, about 90% of the time the instrument panel will display a message that says “Shift to park”, and the electrical components will not shut down. The vehicle is in park, but the computer won’t detect it. I took it to dealer while under warranty, and dealer simply stated that it wasn’t happening. It continues to happen, and I fear that it it won’t shift into park later. As is, sometimes it takes an hour or more to detect that the vehicle is in park. I fear that it will cause a dead battery and leave me stranded. I don’t know if this is a computer issue or a transmission issue. It has been ongoing for at least 10 months. Vehicle was dropped off for repair at dealer in December, 2022, but no repair was performed.

AIR BAGS, UNKNOWN OR OTHER
Bought the truck in 2021. Replaced both outside mirrors during warranty. At about 44000 miles the passenger mirror malfunctioned again. The mirror resets to downward position and when you restart vehicle you need to readjust mirror each time. This is very dangerous especially while pulling the 5th wheel. Received a warning lite for a safety restraint failure. Took the truck to the dealer and was told the passenger side air bag was defective and it was a $1700 repair! Defective at 44000 miles? Are air bags only supposed to last such a short time? This is a serious safety issue that should be addressed and covered by all manufacturers warranties!
