2017 Chevrolet Silverado 2500

Engine wiring harness failure on my 2017 Silverado 2500HD LT 6.6. This time it is the cylinder 7 connector which is a very common complaint by Chevy owners. The wiring harness was installed with wires that were to short for the rear cylinders causing them to fail prematurely. This connector is snapped into position forcing the wires to bend at a tight 90 degree angle. Chevy is trying to force owners to replace the entire wiring harness instead of replacing just the defective connectors (GM 19368140, ACD PT3739). This failure causes the engine to idle and operate so rough that it engages STABILITRAC and forces reduced power mode.

On [XXX], I was driving our 2017 Silverado 2500HD LT 6.6, with my family in Ohio when the trailer brake controller error started flashing on the dash and would not shut off, go silent nor correct itself. It almost caused an accident initially because it was distracting me by making me look down to READ the message. Then we were almost in a dozen accidents as we were traveling too slow for conditions, unable to get off the highway safely, and issues with steering and braking. In 10 minutes, the error sounded 50+ times. We were towing a 36’ 5th wheel trailer suddenly STABILITRAC also kicked on, REDUCED POWER (another message to look down and read), the engine started running so rough (another issues to look down at the gauges) that I thought the engine had blown. We were not in a safe place to pull over and power was cut dropping our speed from 70 to 45 in a 70 zone. Just after going up the hill, we had to continue down other side which we discovered that the trailer brakes were NOT operational. As we were burning our truck brakes going down the other side. The only reset is to shut off the key (which would lock the steering wheel, lose power steering and power brakes while driving). When STABILITRAC appears vital drivers data is BLOCKED. We removed the trailer brake fuse and the trailer battery charger fuse, but the TRAILER BRAKE CONTROLLER messages continued. Even with the trailer disconnected the the messages continued. The trailer brake wire under the truck had exposed wires. Did the exposed wire cause other systems to malfunction? 1.Are the defective wiring harness(es) causing other systems to fail too, and/or can cause electrical fires? 2.Defective trailer braking unit needs to give one warning and STOP. This defect poses a serious issue for anyone towing (or not). 3.STABILITRAC is going to KILL someone because I believe it already has killed. If STABILITRAC throughs the right code it WILL shut down the engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

I was driving with my front and rear motoried window defrost on because its cold outside right now when I started smelling something burning. I turned down the defrost knob. I opened the driver side window to air our the smell when suddenly the rear motorized window defrost sparked up into flames while I was driving. It was in full on burning up in flames. I pulled over and luckily I was able to put out the fire. I have contacted GM because when I google this issue it states GM put out a recall on 2014-2019 Silverado HD trucks but upon speaking with a GM customer representative my truck there is no such recall on these trucks. I could have been killed or worse killed someone else on the road. I am considering getting a lawyer involved with this issue.

The capless fuel filler has failed. The door is stuck halfway open. This is a fire hazard if the truck were in an accident. My son has the same year model truck. Same exact specifications just a different color and hus has also failed. This should be recalled immediately because it's a fire hazard not to mention the emissions of the vehicle.this picture is looking straight down on the filler you can see it is not closed.

When transiting between airport and home in very remote area in subzero temps the DEF warning system suddenly came on limiting vehicle speed progressively. No services were available both at this time of day and in this very remote area. There needs to be some way to override this system in the case of potential life and death. There were no warnings that this system was going to activate, it simply came on. The system had plenty of fluid but it appears the DEF heater failed. A vehicle should have an override for life and safety matters. Vehicle is going to a diesel mechanic for service now.

At about 62,000 miles the vehicle check engine light came on with codes P0700 and P0741, the RPMs go up as you accelerate but will not shift unless you let off the gas pedal. Reaching 5-6000 RPMs. Had mechanic drop transmission pan no metal found. Reading several TSBs on this issue the transmission should be recalled. Also when towing camper there was some electrical issues when the trailer was contacted the truck would not recognize trailer connected, had to shut the truck off for few minutes and restart to recognize the connection. Truck also lost power when trailer was connected and ran very sluggish, also experienced the shifting issues.

I was on a 2 hour drive hauling my 8000lbs trailer when the service trailer brake alarm went off. It constantly dinged the whole 2 hour trip and caused my trailer brakes not to work putting me and my family in danger hauling such a load with no brakes. Not only do I have no brakes but the truck is deemed undrivable due to the constant distractions of the dinging. It also inoperates the message screen to see my speed or to use any other functions like voice commands and radio. I have numerous shops look at it and wasted a few hundred bucks in parts and labor to find this problem with no resolution insight. This is due to a faulty wiring harness somewhere in the truck.

The contact owns a 2017 Chevrolet Silverado 2500. The contact received notification of NHTSA Campaign Number: 21V496000 (Equipment) however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced the failure. VIN tool confirms parts not available.
