2011 Chevrolet Silverado 1500: sudden loss of power

Filed Nov 11, 2022 · Driver assistance, Engine · MI

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.

**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 .. it has only 100k miles but somehow I am stuck using my dads old truck with 330k miles on it which seems to be more reliable and is 12 years older … sucks to pay over 500$ a month for “ your dream vehicle “ that you can’t even drive or get any real answers to what or where the problem is coming from … seems that thousands of people online have the same problem but yet no one has any solution .. Now that I’ve almost been in 3 serious accidents I decided I have to say something, 2 of these times were over 70 mph on a California freeway !!! Something must be done !

Stability control alarm blinking ,traction control alarm blinking,, speedometer going erratic, brake lite staying in alarm,cruise control dropping out,power loss temporarily. Shifting between gears (auto xmission) was very rough.this was an electrical system that grew steadily worse. Gm dealership had to replace the ebcm, and the chassis wiringharness. Severe corrosion. Vehicle never driven in salted roads,never flooded,never driven thru water. The location of the ebcm is poorly designed. Dealership said they have never seen a module this corroded,as it was in pieces when they pulled and opened it. I waited 4 months to get it fixed, as a early mechanic saw an electrical fault, but couldn't pinpoint it as it wasn't staying in fault. He said it needed to get worse before it could be properly diagnosed. Had to bring to dealer for repair as it got progressively worse. Cost me $1878.36 to get repaired.

Takata recall and another issue of power loss----- I have taken my truch to the dealership to have the takata air bags replaces and they told me that they do not have the parts to replace them. Power loss: I can be driving and the vehicle goes into a drastic and immediate power reduction. I have nearly bee rear-ended several times and the vehicle jerks suddenly throwing everything forward as though it is nearly a sudden stop. It will not drive over 20 MPH when this happens. It will not reset until I pull over, remove, and reassemble, the battery cables. This happens during, and following, every rainy day. It also happens for no specified reason. It happened 3 times in the last 24 hours--no rain at all.
