General Motors LLC (GM) is recalling certain 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. The battery positive (B+) cable rings may have been manufactured with excessive glue, potentially causing an intermittent electrical connection between the B+ cable and alternator.

I was enjoying my day off with my family while driving torch highway when I try to pick up my speed to merge in, but my truck was not responding, when stepping on gas, I certainly did not saw any of them gears change I had to put to the for our safety and had to call a tow truck.
Vehicle speed control, Engine, Apr 1, 2025
Component/system that failed: The transmission control module in my 2020 Chevrolet Silverado 1500 has malfunctioned. The vehicle has issues with slipping between gears, rough shifting, and hesitation when accelerating. This component has already been inspected and diagnosed by a certified Chevrolet dealership, and the part is currently on backorder. The vehicle is available for further inspection upon request. Safety risk: This issue poses a serious safety risk to myself and others. The gear slipping and delayed response when driving—especially when merging onto highways or changing lanes—creates unpredictable behavior that can lead to an accident. The truck sometimes fails to engage gears properly, which makes it dangerous in traffic situations. Diagnosis confirmation: Yes, the problem has been confirmed by a Chevy dealership service advisor (Jose Diaz), who provided a formal quote and diagnosis for the replacement of the transmission control module. Inspection by others: The vehicle has not been inspected by police or insurance representatives, but Chevrolet Customer Assistance is currently reviewing the case, and I was advised to submit this documentation. Warning lamps or symptoms: There were no warning lamps initially, Symptoms include slipping gears, hesitation when pressing the gas pedal, jerky shifting, and difficulty accelerating smoothly. These symptoms have progressively worsened over time. Additional context: I have learned that many 2020 Chevrolet Silverado trucks have been recalled for the exact same issue, but my VIN is currently not included. I believe this is a manufacturing defect and that my vehicle should be considered for inclusion in the recall or further investigation.

From the time my vehicle had 30,000 miles on the engine, the engine light would come on and stay on with no apparent reason. I would take my car to my local Chevrolet dealer each time (by this time the light had gone out) and they could not find a problem. One technician told me that it sounded like a lifter problem that they were experiencing with these model vehicles. This happened approximately 8 to 10 times before the lifter failed. In January 2025, while driving on the Interstate Highway I experienced a sudden engine vibration and immediate 50% loss of power. Upon returning home, I took my truck to my local Chevrolet dealer where I purchased my vehicle. Upon inspection, I was told that it was apparent that a hydraulic lifter had failed. I left my vehicle at the dealership for the repair of the failed lifter which cost me $4,800. Two months later, I experienced the same problem with the engine, more violently vibrating. I again took my vehicle to the dealership and they confirmed another lifter had failed and took it in for repair under warranty from the prior lifter repair. I had again experienced more than 50% engine loss and had to get off of the interstate and travel on a side road because I could not maintain a speed over 45 to 50 mph. They repaired the same failed lifter bank that they had repaired the first time. Now, I am holding my breath, just waiting for the lifters on the other bank to fail for me to have to put in another $4,800-$5,000. I believe that this is an engine flaw that Chevrolet knows about. They have done nothing to fix this issue and have left it on the backs of the customer. Chevrolet needs to be accountable for these types of problems!
