2024 Chevrolet Silverado 1500

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on several occasions, the vehicle lost power and then stalled. The vehicle was restarted after each failure. The check engine warning light was illuminated, and the message "Reduced Acceleration - Drive with Care" was displayed. The vehicle was taken to a dealer on several occasions, and the dealer retrieved DTC: P2732 and P0700. The contact was informed that the valve body needed to be replaced, and the transmission was leaking transmission fluid, but the leak was not located. The valve body was repaired, and the transmission fluid was topped off, but the failure reoccurred 2-3 months later. The manufacturer was not notified of the failure. The failure mileage was 10,900.

When driving at slow speeds, less that 10 MPH, the engine shuts off and vehicle shifts to neutral. Message is displayed on driver console Press Start Button to restart. Only the engines shuts down as all displays, entertainment center and controls are still displayed. Pushing the start button restarts the engine. This has occurred several times since purchasing the truck however it has occurred 2 times in the last 45 days. This issue has happened while driving in slow traffic on the interstate and is concerning when it occurs as I come to a complete stop without warning creating a possible rear end accident. It was first reported to my Chevy service dealer on 2/21.2025, The Chevy tech stated they could not duplicate the issue so no remedy has been offered. The issue continues to happen and I will be returning to my Chevy service center for another report of this continuing to happen.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from Ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the Lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home.(this part of not going in reverse I do have on video) Once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave Walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

I had my oil changed and the next day the check engine light came on. I looked on the Chevy app to see what it was and it said Varuable Valve timing issue. I Click further into the app warning and it said, Engines equipped with this system use sensors that regulate the opening and closing of the intake and exhaust valves to optimize performance and efficiency. I live 3 and a half hours away fro. The dealership so I had some mechanics look at the truck just to see if they could pin point what the issues was exactly. They didnt pull or work on anything just looked around listened and plugged in a code reader. The code reader found some codes that had to do with 3rd stage valve timing issues and VVT. And 1 or 2 other codes. But they didnt know exactly what was wrong. I had my oil changed 1 more time to see if maybe that was the issue. It did not fix the issue. I called the dealership to make a appointment. I brought it in and get a call that the cam shaft need to be replaced. It was in the shop for about a month and when they said it was ready. I went to pick it up and as I was pulling out of the dealership parking lot. The check engine light came on and I drove back and it had the same codes. And now it is being worked on again. The safety side is if it looses power while im going 65 mph it could be really dangerous. Becaue there could be metal shavings in the oil possibly.

My truck engine stopped working while driving down the road causing me to lose power and I was not able to exit the roadway. There were no warning or messages until the loss of power and dash stated to "restart the engine". This was not possible. The truck was towed to a Chevy dealership and they confirmed the engine seized up do to unknown engine failure. This is a 2024 6.2L engine with 45000 miles that is NOT under recall. The dealership replaced the engine under the powertrain warranty.

After taking in to dealer for recall diagnostics and higher viscosity oil change a couple months later. Heard a noise while driving on interstate, lost cruise control, stability system, engine light came on with a ECS. Kept driving on the interstate until we got to a red light and the engine died. Cranked starter but hard to start and ran rough and died multiple times. Feathered throttle to get over 1K RPMs to get it off the street. Towed to nearest Chev dealer. P300 code. Tore engine down. Here is what dealer documented: CUSTOMER STATES CHECK ENGINE LIGHT IS ON WITH SERVICE TRACTION & SERVICE ESC MESSAGES. ENGINE IS RUNNING ROUGH AND WILL STALL. TOW IN. Valve Spring Replacement - Replacing the faulty valve spring on the cylinder 7 exhaust side is necessary as it is causing the exhaust valve to remain stuckopen, leading to engine misfire and over 80% leakage in that cylinder. This service can help restore proper engine compression and improve engine performance. Op.1 CEL -CEL: Customer states 1. replaced the exhaust valve spring and valve spring seal. reinstalled components with new seals and cleared dtcs. started engine and verified the engine starts and runs but having multiple cylinder misfires. reset engine fuel trims and brought engine to operating temperature and let it run for some time. other cylinder misfires went away but still found a dead misfire on cylinder 7. removed and swapped spark plugs with no change. noted the spark plugs have some exhaust build up on the tip due to the faulty exhaust valve spring. performed a static compression test and found the compression to be 175 psi and a running compression test with a smooth build up to 125 psi. checked spark and spark was good. tested the injector system using the AFIT test and found the test to pass indicating no faults with the fuel injectors. performed a cylinder leak down test and found no cylinder leakage coming from cylinder 7. put engine back together and cleared dtcs. reset the throttle
