ELECTRICAL SYSTEM
In October of 2020, my avalanche only would start in winter after disconnecting and reconnecting the battery. It was also on numerous occasions go into limp mode while driving at normal city speeds meaning it wouldn’t go above 25 miles an hour. The entire dash would light up. It threw numerous codes. Had to be towed to get it looked at but then would mysteriously start without issue. I took it to young Buick gmc in Layton Utah with no resolution. Finally in December 2020 it was determined by now Heritage Chevrolet in Evanston Wyoming to be the Onstar module. This part was no longer available and couldn’t be replaced. The dealership’s solution was to wire around the faulty part which has allowed the truck to start and no longer go into limp mode from 70mph on highway to 20mph without notice. I immediately got a hold of Chevrolet to get a satisfactory answer about why I couldn’t get the part that was making the vehicle unsafe to drive. They said the part was no longer being manufactured and it wasn’t their problem sorry about the inconvenience Case number [XXX]. I did have the dealership wire around it so I have the truck working, but Chevrolet did not care about the truck going into limp mode suddenly on the highway and it could have caused an accident. They not not offer any compensation for the part not being manufactured and according to to your website if a part is causing a safety issue they are they are required to have that part fixed. I am still upset about their lack of support and service and want Chevrolet held accountable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
I am an owner of a 2013 Chevy Avalanche and must say that i enjoy driving this vehicle. The problem that i have is the vehicle has been going into Engine Power Reduced Mode. This mode makes the vehicle hard to accelerate to highway speeds. The vehicle will have a code of P2128 or P2138 which is an accelator pedel ciruit problem. I changed the acceleator pedal and did not solve the problem. I changed out the Throttle Body Sensor and still the problem remains. On the dashboard it will show Check Engine Light on, Service Stablinktrac light on, and Service Traction Control Light on. I have seen other vehicle owners experience the same problems with their vehicles and told that there was no recall and have to pay for the repairs out of pocket. These are very well made vehicles but when they going into Engine Power Reduced Mode, drive ability is diminished.

ELECTRICAL SYSTEM
- My dashboard has had a large crack in it for some time now and I am needing it to be repaired as I am not the only one with this issue. - The dashboard is considered the cover for the instrument/control panel of my vehicle. It is not in good shape due to this crack which would cause a greater hazard should the air bag deploy and cause the dash to send pieces of plastic flying everywhere. - This problem has already been brought to GM's attention in a lawsuit. - It has been inspected by myself and other passengers in the vehicle and a cause for great concern since I have no idea why the crack even appeared after having taken care of my truck very well since the first day I've owned it. - No warning lamps that I am aware of but then again, not sure if issues I've faced since owning it are due to this crack.
