MY Vehicle (2023 Chevrolet Silverado) has been in the shop over 9 times due to issues with the radio. I bought Truck on June 2 and since then have had truck in several times due to a radio issue. Each time i have taken truck in i have been told it's a "Software Update" should be good now. Spoke with GM Customer care and their exact words were shut the radio off drive without it. The radio volume with go full blast while driving even when the radio is turned down low. When this happens, it scares you some wheel jerking. I could see someone getting hurt while this is happening, upon looking at a few different forums i am a part of this is a concern and affects a lot of drivers. The fact GM customer care simply states just shut the radio off is a real concern, We as consumers pay a lot of money for these vehicles this in my opinion is not the correct response. They don't have a fix for this yet is also what the woman from customer care had to say. this truck is over a year old. how is this possible? GM is aware of this issue but has done nothing but continue to put people's lives in danger. I don't think telling their buyers to turn off the radio and drive without it is what should be getting said.

No idea where the problem lies due to inconsistent trouble codes, the truck will randomly start jerking and sometimes kill itself after throttle won’t respond no matter the speed.

No idea where the problem lies due to inconsistent trouble codes, the truck will randomly start jerking and sometimes kill itself after throttle won’t respond no matter the speed. Every time I’ve had somebody drive it, it does not act up for them. I’ve had several parts replaced with the same problem coming back 50+ miles later. When it gets ready to shut down it throws the check engine light, service esc, collision light, and traction light, then says speed reduced or speed will be reduced in 175 miles. I have video evidence of all of this.

At approximately 9k mi the engine performance (2.7L MAX Turbo) started to become intermittent. I always record the fuel milage, and always drive the same way, to/from work. NOTE: Displayed mpg calculates within 1% of actual. We can assume the driving habits are identical each time. While driving on the same tank of fuel for a week at a time: one day heading to work the indicated mpg might be 17 mpg. Driving home, about 10 minutes into the drive, it might increase 25 mpg. The following day it could be the same 17/25 mpg or it might be 25/17. The weather is somewhat dependent, whereas around =<43F the 17 mpg is almost a guarantee. While the indicated lower mpg is displayed, a direct lack of engine power is noticeable. The accelerator is dangerously non-responsive, all the while of pressing the pedal >3/4 to the floor. There is also no downshifting from the transmission whatsoever. To make the engine respond to change, the accelerator must be fully pressed to the floor, forcing the transmission into a lower gear and causing the engine to 'wake up'. When the mpg is above 20 or 21 mpg, (and temperatures >50F) the engine performs normally, where gradual accelerations to the pedal increase the engine speeds and down shift as expected. I have contacted GM through the 'MyCheverlot' app a couple of times, and have taken the truck to the dealer twice for this. Both times from the dealer it was stated that since the engine light was not on and no codes were stored, there was nothing that could be done. The dealer installed a software update and sent me on my way. Lastly, the 4WD is now making a grinding/rubbing noise, since the software update and overcomes the engine power while making turns from a stopped position. If no acceleration is applied, the truck will come to a rapid complete stop if rolling <10 mph. Truck is a LEMON!!

ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement.
