ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
Dash Warning: Check Engine Light, "Engine Power is Reduced!" and Traction Control. Code Reader Results: P2138 (APP) Accelerator Pedal Position Sensors - Not Plausible. Replaced with NEW OEM Part(s) - APP, Electrical Throttle Body and M15 Fuse - which did NOT fix issues and now due to safety concerns (further damage to vehicle and personal preservation) will be towing to dealership for diagnosis. Believe to be a known WIRING issues most likely due to WATER exposure/ SHORT in Connectors. - See IP, ECM/PCM and possible false activation to the APP circuit. This should be a RECALL due to the severity of mechanical issues of the malfunctioning system.

POWER TRAIN, WHEELS
Purchased this vehicle from a used car dealership 2 months ago. Now the transmission seems to be going out with 132,000 miles on it and funny noise from the transfer case. I have researched and found numerous complaints about the drive train on this vehicle and as a disabled veteran I don't have the funds to have it fixed. How can I get a recall in place for this issue?

ELECTRICAL SYSTEM, ENGINE
Entire system (everything) shut down without warning, sometimes kick back on, and other times not at all. Extremely dangerous as it will occur no matter traveling on highway or turning a corner in a parking lot. There are discussion boards in which many people have experienced this problem and clearly it is because of "Bad Battery Cables" and common within the 2014-2018 models. My truck is currently in a dealership garage to have the cables replaced and I have to have a rental car while the cables are on backorder for 5 to 10 days (maybe longer). How is this not a "recall" when so common and so dangerous? Dealership could see in a diagnosis that power had been lost and communication lost, over and over and over. There has never been a dash warning light come on at all.

SERVICE BRAKES
There is a recall for a brake issue on Chevy Silverados of the same year mine is doing exactly the same as the recall calls for but when I try to get the repair for the recall I’m told my vehicle doesn’t have the recall. The problem almost causes crashes due to the brakes not working when the pedal is pressed.

FUEL/PROPULSION SYSTEM, POWER TRAIN
While hauling a trailer I received a warning tone and looked down to read the message, "reduced engine power", and the service engine light appeared all at the same time. The engine shutoff at the same time I received the warnings and didn't allow me to safely pull off the road.. I lost power steering, power braking, and controlling the vehicle and trailer while coasting to the sholder was difficult. Fortunately it was early in the morning and I was only traveling 35 mph on a straight road, and no other vehicles were on the road. If I was on an interstate traveling 55+ mph or on a curvy road it would have caused an accident or worse. I was very fortunate. This was the first time I experienced this problem and hadn't received prior warning messages or lights. The truck would not restart and the truck and trailer were towed to the dealership. The diagnosis was a failed "Fuel Pump Control Module." After waiting several weeks the replacement Fuel Pump Control Module did solved the problem. I kept the failed Fuel Pump Control Module and is available for inspection. Please investigate thoroughly! I was extremely fortunate the part failed when it did and I was able to walk away unharmed.
