We were pulling a 5th wheel camper on the highway at 62 mph. We experienced a series of sudden breaking sensations. Engine RPMs did not change during these events. We had been traveling for 45 minutes and decided to cancel our camping trip and return home because we were afraid of getting stranded away from home. The sensation felt like a sudden strong application of the rear brakes. It was very momentary. We turn around and shifted the transmission to "L" which limits the highest gear to 7. We did not have any more incidents. When we were close to home we shifted back to drive and the problem returned. We were concerned with a complete loss of control or motion if the problem got worse. We have an appointment to have the truck looked at next week. There were/are no diagnostics codes visible on the dash.

The infotainment system regularly stops producing audio. This applies to all audio, including turn signal, navigation, radio and Apple Carplay. Yes, it's available to inspection. While it's not a huge safety concern, there have been a couple times it's quite working, and I was very distracted by the audio cutting in and out. A few times I've driven down the road with my blinker on because I couldn't hear it blinking as it comes through the speakers. Yes, I've taken it to the dealer, they apply software fixes that they know won't correct the issue. It starts right back up a few days later. No, it has not been inspected by the manufacturer, other than their authorized service center. No warning prior to it appearing.

On April 13, 2026, I experienced two safety-related malfunctions while driving my 2025 Chevrolet Silverado 3500 LTZ on a two-lane highway in light rain. At approximately 6:24:05 PM, the windshield wipers stopped in the upright position for about 2–3 seconds while the vehicle was in motion, causing a temporary loss of forward visibility. At approximately 6:26:56 PM, while traveling around 65 MPH, the forward collision/adaptive cruise system falsely detected a vehicle in my lane when none was present and applied sudden, hard braking without driver input. This caused a noticeable forward pitch of the vehicle. At approximately 6:27:13 PM, the system again indicated a vehicle ahead when there was none. Road conditions were wet, and this unexpected braking created a risk of loss of control or a rear-end collision. The systems involved include the windshield wipers and forward collision/adaptive cruise control. The vehicle is available for inspection upon request. There were no warning lamps prior to these incidents. The only indication was a false vehicle detection displayed on the instrument cluster and heads-up display. These issues have not yet been reproduced by the dealer, as they were just reported to both the dealership and GM. The vehicle has only been inspected by the dealership to date. The truck also has ongoing issues, including frequent audio cutting out (6+ service visits, unresolved) and intermittent failure of the camera system to activate, which has been previously documented and not corrected. Dashcam footage is available for both incidents and can be provided for review. These issues appear intermittent and without warning, making them difficult to anticipate or mitigate during normal driving. The unexpected nature of both the wiper malfunction and unintended braking increases the overall safety risk, especially in adverse weather and highway conditions.
