| Warnings problems |
Concern: various check engine lights occurred and vehicle making noise from the motor. Park collision assistance codes, emergency brake engaged code, when it was not on and could not move vehicle. Safety concerns about vehicle completely quitting or braking causing an accident, along with engine issue with only 5,161 miles on the motor of a 2021 Chevrolet silverado. Cause: scanned data indicated p0300 stored miss fire #4 cylinder on right side of engine, lifter noisy, push rod #4 intake bent. Correction: removed intake, exhaust manifold, value cover, cylinder head, right side replaced all lifters, one push rod, related gaskets, reassembled engine.
Upon returning home after a short drive I pulled into my garage and almost drove through the wall… I purchased parking assistance and it was not provided. The feature apparently failed and turned off at some point without clearly notifying the driver. I don’t know if it provided a silent notice that automatically dismissed but it certainly did not notify me when I really needed it… low speed. The park assist light is indeed off now when the vehicle starts. Clicking the button reports “park assist off” even though it already appears off and is certainly not providing the intended safety feature. Clicking the button again does not turn the light back on but if clicked again it will again report it was disabled. This is strange and confusing for the driver. Using the infotainment screen one can toggle “park assist” off and the drivers info screen by the speedometer will finally say “park assist off”. Turning the feature back on in the infotainment screen actually turns the park assist button back on for about 5 seconds then it silently turns off and the driver is not warned that the system is not working. The driver is not properly warned of feature failure even though it appears the software knows it is not working. The little button goes out but the driver message screen does not warn the driver. This failure and poor awareness is a safety risk. Yes, we are unlikely to be parking super close to someone but we might indeed park near a gas hot water heater or similar hazard in work trucks. The driver must know if safety features failure during driving. Otherwise they are potentially more hazardous than vehicles without them. Drivers will by design rely on these features and must be warned if the vehicle knows they have failed. I don’t love that the vehicle has already had a failure with only 1695 miles but this dangerous software concerns me more.
Bought the truck 2 weeks ago and put 500 miles on it. Upon entering I got an alert on the dash saying esc power steering failure, parking sensor failure and abs failure drive with caution. All these alerts happened while the vehicle was parked and barely turned on. Sure enough I try to turn the steering wheel and the power steering was out and the parking sensors were out. I didn't try the brakes since I was not moving and parked.
The antilock brake system (abs), brakes, and electronic stability control system (esc) might not illuminate. This could cause the driver to not know if any of these systems are inoperable.
