I am fully aware of of GM’s Hydra-Matic 8L90 transmission or Hydra-Matic 8L45 transmission on the 2015-2019 models. My wife was driving with our kids on the highway yesterday and the trucks immediate shaking, increased high RPMs, slow acceleration and violent downshifting. Scared them very much on the highway while going at the normal speeds of 65mph trying weave through traffic and make it back home on top of that. With zero warning and this having happened on my first 2011 Chevy Silverado as well. I know full well there are more class action lawsuits against GM. Them being allowed to get away with this consistent problem and not owning up to their failed products is unacceptable.

ELECTRICAL SYSTEM
Another day another code. P11DB (NOX upstream). Now I am at NOX downstream, NOX upstream, DEF pump, cylinder 7 wire connector, Trailer Brake Controller wire harness, temperature sensor, and a dozen chafing wire harnesses because they are pulled to tight, have extreme bends in them or are rubbing against the frame, bumper, etc. Chevy recommended that I replace the cylinder 7 injector which was not the issue. At this rate if I paid Chevy to diagnose and repair this vehicle I would easily be $5,000+ in repairs since Chevy wants to do cab-off maintenance on everything now. This is manufacturer defects and consumer fraud and NTHSA is not holding Chevy accountable for. My Dad has a 1978 Pinto that he can start up and run to town but my 2017 Silverado can't even leave the farm.

ELECTRICAL SYSTEM
This is my 3rd complaint within 6 days. The entire electrical system in this 2017 Silverado 2500HD LT 6.6L appears to be committing suicide. First it was the Brake Controller Unit, Diesel Injector Connector (cylinder 7), P1050 DEF Level Sensor, U029E NOX Sensor Module 2 Communication Lost, U02A3 Lost Communication With Particulate Matter Sensor Module, and now P018B Code: Fuel Pressure Sensor "B". At what point will the manufacturer be held accountable for manufacturer defects on this vehicle (including the Dorman 603-009 Coolant Reservoir)? Every pump and sensor on the truck is failing within a week of the trailer brake controller failure? WHY is every wire harness on this vehicle (like so many others) failing? I cannot trust that I can even drive this vehicle without either STABILITRAC shutting it down or the defective wire harnesses catching fire.

ELECTRICAL SYSTEM
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.

Radio randomly turns volume to maximum level and doesn’t allow you to reduce it. I can only fix it by turning truck off then on again.

SERVICE BRAKES
Brakes failed. The brake assist pump disintegrated, sending metal fragments into the Motor's oil circulation system. I was able to stop the truck using both feet and applying extreme force to the pedal. The dealer identified the problem. The "Brake Assist" warning light came on during the episode.

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.

We Bought a Chevy Silverado 1500 truck used in Nov 2021for purpose of towing RV trailer. In having axel bearings packed on trailer March [XXX], 2024, the RV mechanic noticed no wear or brake dust. He checked and determined RV brakes had never engaged and found no power to the RV brakes in the plug in port on back of truck. Took to dealer, Chesrown in Delaware Ohio, on [XXX], 2024. After having truck all day they said issue was brake modulator which they reprogrammed. We hooked up RV trailer and brakes still do not work. Hand brake controller on dash will engage the trailer brakes , but not the foot brake. In researching online, there is a great deal of discussion about GM knowing about and not addressing the issue. There’s a known defect in a wiring harness between two of the body control modules. This part is known for broken wires and for connective issues. We reached out to GM Customer service at 800-222-1020, who took our information and said they would contact the dealer. We took truck in today and explained again what the issue was and what we had learned from our research. There are currently several recalls on 2022 and 2023 Silverados for the same trailer brake issues. GM needs to take responsibility for this critical service issue!! We CAN NOT tow a RV trailer WITHOUT BRAKES! When we asked the service manager why the tow package was not part of the inspection process when they took the vehicle in and placed it for sale as a used vehicle, he said they don’t do that. Seems to us, that when a dealer sells a vehicle, all parts should be in working order. Especially with a factory installed tow package. PLEASE research and contact GM and have them issue a RECALL on ALL of their vehicles with factory tow packages to ensure the safety of all of those driving them! You will find numerous forums online where the biggest complaint is the trailer brake system not working and people very frustrated with the lack of response from not only GM but the dealers. THANK YOU! INFORMATION REDACTED PURSUANT TO THE FREEDOM O

At 83,000 miles the transmission failed. We bought this car from a Chevy dealership with 35k miles in November of 2021. We have performed all required maintenance. If GM knows there is a transmission issue with these trucks why won’t they help their customers? It’s a 7k bill on a truck with many more payments and that has less than 100k miles.
