**randomly at any given speed ** First the radio system will randomly turn off then moments later... stabiliTrak off flashes followed by abs and traction control lights on dash then suddenly my Chevrolet Silverado has a mind of its own ! The door locks will flicker uncontrollably , and the vehicle just suddenly has a loss of power while rpms and gauges are continuously moving while you are unable to even move the vehicle .. this is a ongoing problem since 2019 , that no one seems to have an answer too .. I've taken it to 3 different mechanics and still no answers ... when it first started happening it was super random and would happen a few times a day but then not happen for months on end then all of the sudden now it is happening several days a week .. I'm currently scared to even drive it which is horrible considering the amount of money I've put into this truck .. …
Hybrid system failed while driving resulting vehicle becoming disabled on the road. Took to GM shop, they informed that the Hybrid System failed. Parts are unavailable because GM discontinued them. GM shop is not willing to replace with used battery due to the lack of reliability "we would have the same problem just a few miles down the road". GM shop bipassed hybrid system resulting in the vehicle only working if it is on a trickle battery charger. Filed complaint with GM and GM told us they cannot help because the part is discontinued. This vehicle cannot operate without being on a trickle charge which is a hazard to all people on the road. GM discontinued a part that is vital to the vehicle's safety and usability. GM provided no resolution, therefore putting all 2011 Chevy Silverado Hybrid vehicles at risk for immediate and unforeseen vehicle failure.
The software that makes the truck work as a 4 cylinder truck has caused the engine light to come on and causing a code P0300 various engine misfire. The misfire is caused by the lifter spring causing the lifter to remain in the down position. The down position is against the can rod and as the cam rod rotates, this causes the lifter to break at the bottom and causing the can rod to also break which will cause an engine failure while drinking and the motor will freeze . All GMC and Chevrolet vehicles with this installed should be recalled. Everyone has been fixing it themselves by replacing the part(s) once a pinging noise is heard at 50,000 miles. Basically every 50,000 this will need to be fixed. Some people are turning off the 4 cylinder software to avoid the problem which in both cases, uses more gas and also idles higher.
The worst problem I have with this vehicle is that it will cut power to propulsion without any warning. I was driving down a suburban roadway, not on the freeway, thank God. When the truck's automatic gear shift wouldn't engage, I went from going 30 mph to 5 mph in seconds. The accelerator pedal wouldn't respond, I managed to coax my truck into a parking lot and restart the engine. Other times the head lights will not come on. Just today, I turned on the left turn signal and the Stabilitrack warning light came on, plus the radio made a brief noise of static. This particular issue appeared and disappeared in one second. I'm concerned that these problems are a manufacturer's mistake, and I want it fixed as soon as possible. My mechanic has tried repeatedly to find the cause but has been unsuccessful.
Vehicle door locks activate lock and unlock while simultaneously downshifting the transmission, the engine dies, the dash cluster stops working, engine starts again, dash cluster begins working again. After this occurs, when the vehicle is shut off, there is a loud "pop" sound heard over the speakers and no interior lights. The vehicle may or may not have any cab power. Cycling the ignition provides little to no help. After the vehicle sits for a while, it may or may not start again. The vehicle stereo will randomly change from FM to aux. The a/c panel will flicker and the blower motor will fluctuate. This can also be seen while watching the battery gage on the instrument cluster. It will go from around 14 volts DC to around 9 volts DC and back up again.
After 2 weeks of owning the truck which we are paying on it had to be towed 3 times stalling out and leaving leaving my family,my children with us at least once, and stranded in high traffic roads. We took it back to the dealership and they replaced the fuel pump and the fuel light came came on the very same day we picked it up. Now over a week after getting it back it has stranded us again,this time with our 3 children with us. This is on a Friday evening during rush hour. We manage to pull to a side road and off to the side a bit,but not fully. People are driving by very fast now as we wait for a tow.
While driving, all the sudden my check engine light came on (flashing), and my stabilitrack light came on. The engine started running really rough, and lost power. It is like major misfire. Upon reading up on this, it is a problem with this type engine. I saw about 2000 people with the same issue. Nothing works to resolve this problem. Coils, plugs, and wires were replaced, and still the same.
AFM/DOD lifter failed while driving which causes multiple systems to go offline including Traction Control, stability control, ABS just to name a few. This happened while coming off freeway which can be a safety risk as vehicle was at higher speeds. This is a known GM problem with 5.3l engines and should have been addressed years ago.
