2017 CHEVY SILVERADO 2500HD LT 6.6L It all started on June 15, 2024 with a TRAILER BRAKE CONTROLLER (chafing wire that was grounding and shorting against the frame and bumper) resulted in a barrage of issues. Our truck being down over a month and throwing (so far) 16 codes just on the first 2 scanners. It has also taken out the TPMS too.

Most of the codes referring to voltage to high and voltage to low. The entire truck is shutting down electrically and we can only assume that this will result in one of two options. First is that the vehicle will catch fire because of the system wide KNOWN WIRE CHAFING electrical issues. Second is that the vehicle is totaled / junked since Chevy will neither recall the KNOWN issues and is too busy changing customers for FRAUDULENT repairs that their vehicles do not need. Take for example P0307 which Chevy wanted $165 for the diagnostic fee and over $650 to replace cylinder 7 injector along with time for the repairs (over $1,000) for a $14 KNOWN wire connector issue that Chevy is performing fraudulently. Chevy CANNOT continue to lock the center information screen. That information is vital to our driving.

While driving, the check engine light comes on and "reduced engine power" is illuminated on the dash. Stepping on the gas does nothing. The vehicle just coasts along and runs rough. I have to pull over and shut it off for a few seconds. Sometimes it doesn't clear the problem right away and needs to be restarted several times. There is no rhyme or reason as to when this happens. It happens almost every day, on busy expressways or on main roads and side roads. The gas pedal loses communication with the throttle body. This is nerve wracking when driving 65 MPH on the expressway and all of a sudden the vehicle wont respond to stepping on the gas pedal. Trying to get over several lanes to the side of the road is dangerous when there is no acceleration. It is also bad when on a busy, main road, the vehicle "acts up". I have to pull over, blocking traffic, until I can get it going again.

2001 silverado hd 8.1l engine 51,009 miles. Experiencing issues associated with the federal safety agency id # 07v521000. I have had it checked and the scanner shows a crankshaft position sensor failure. I took it to the dealer and was told that they will not fix it due to my VIN number being outside the recalled groups. Even though it is in the date range of the effected units. I did some research and found that my truck has the same exact part number of the item that is failing. This has caused me to almost be rear ended 3 times and several other times where it quits at highway speed or in an intersection and I loose good steering and braking control. The last time (last saturday) left me and my 2 children (4 and 7) walking in a snow storm with poor visibility and risking freezing temps and almost getting hit by other traffic. It will usually start again but then runs rough but sometimes I have to let it sit for an hour before it will start. Vic canever chevrolet in fenton mi is the dealer that said that they will not honor the recall due to VIN number not in their system as a recalled unit and the gm customer service hotline would not assist me either.
