2023 CHEVROLET SILVERADO 1500 Complaints

Engine seized at 330 miles. I’ve recently seen the investigation into crank bearing failure on the L87. We upfit new vehicles. This was a test truck. We pulled oil from another identical chassis with 10 miles on it and sent it in for testing to a 3rd party. At 100C/212F the viscosity was under 7 and it should be 20. It is our belief that GM has faulty bulk oil they’re putting in new vehicles.

There were no symptoms prior to the engine failure. On January 14th, 2025 while driving 58 miles per hour heard a sound that sounded like a slap on the back window. After the slap sound I noticed the engine was not running as normal. There was also a sound coming from the engine like metal rattling around. A few minutes later the check engine light appeared in the instrument panel. Had the vehicle towed to the nearest GM dealership and was informed that the thrust bearing went out which may have caused damage to the crankshaft.

I was driving and received a check engine light with “Service ESC” and traction control was disabled. Performed diagnostics and found P0300, P0304 and P0204 all relating to cylinder 4 misfire and injector issues on cylinder 4. Truck has just over 47,000 miles and may be related to the lifter issues that plague this engine design.

2023 Silverado with 10 speed transmission. 20K miles. On 11/30 received "Reduced Power" message, quickly followed by "Service Transmission Now Unable to Shift Soon", which was quickly followed by "Service Transmission". CEL came on. Transmission was shifting erratically, and not shifting into higher gears. Clearly a safety concern. Dropped it off at a local dealer on 12/1. Dealer service advisor contacted me 12/12, saying they were finally able to diagnose the problem and the transmission needs a new valve body. However, the valve body is on back order and there is no estimated time for when it will be available. The internet is awash with stories of the same issue with GM's 10 speed transmission in the light duty pick up trucks, leaving owners waiting for weeks, even months before their vehicle is repaired.

My tailgate randomly opened while the vehicle was parked this fall on three separate occasions. I see there was a recall (N232426400) but it only included the Canadian equipment. Can we be certain the Canadian equipment wasn't used in my vehicle? If the Canadian equipment was faulty it's not a stretch to think the American or other equipment could be too.

Took truck to dealer for diagnosis and repairs. was called and informed That the Coolant control valve was defective and that NO parts were available at this time, and that the expected part arrival dat was the third week of January. When asked if the truck was drivable was told that it wasn't recommended due to engine overheating concern and vehicle going into LIMP mode and leaving me in an unsafe situation if traveling on a highway or at freeway speeds.

Vehicle goes into reduced power mode and prevents safe acceleration in traffic and is a major safety concern. The Coolant Control Valve is the issue which has been a problem in the Silverado for a few years. This part is also on national backorder.
