Odometer Fraud. The contact purchased a 2018 Chevrolet Silverado 1500. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale.

Torque converter failed which led to premature transmission failure at 115,000. Known common issue with 6L80 and TSB advising this. No recall

Since purchase in 2018, my pickup truck has had a ticking and banging sound which includes rough idling and a check engine light. During routine maintenance, oil changes, etc. I have continued to ask about the noise but GM technicians have said nothing is wrong. In November 2025, i took the truck to a local shop for an oil change and that’s when I learned it has lifter issues. Upon investigating whether other Chevy Silverado truck owners are experiencing the same thing, I’ve learned about various recall and extended warranty programs offered by General Motors. I’m wondering when or if my 2018 Chevy Silverado might be included in a recall or could i be offered an extended warranty?

2018 6.2l engine dropped 3 lifters at just a little over 70k miles. Vehicle is my wife’s and almost caused her and my child to have an accident while traveling on highway at posted speed. Vehicle lost power that resulted from premature engine failure resulting in vehicle losing power to the brakes and steering while in heavy traffic. This directly affected my wife and immediately caused her to have a panic attack. Vehicle has always been maintained to the highest levels. This issue affects a substantial amount of these motors around the same mileage. Very bad and unsafe AFM design that is common among vehicles with this engine. Transmission is also experiencing studdering/vibration issues. Right now we have paid out over 5k for engine repairs. Transmission needs repaired and presents a constant safety risk to our family as well as others. GM needs to stand by their products as we consumers put our trust in these vehicles to be safe and to last more than a few miles. My wife and I both have to work and unfortunately we don’t have the extra funds to purchase another vehicle or to keep shelling money out to fix a basically new vehicle that we have babied. Please help us hold companies accountable for their failure to stand behind their products. Thank you for your time.

Number one electrical system left side wire harness manufacturer installed in properly, not watertight and ran through a pinch point causing wires to break. Safety was put at risk due to power failure from fuel pump and brake lights failing which could’ve caused a potential accident. Been confirmed by an independent service center. Reached out to the manufacturer. They said there was no recalls. It was very unhelpful. On the failure happened a light did come on. Number two media end navigation system this is a safety risk because at certain times it will switch between screens at will by itself. They will also put calls on hold, causing you to instinctively reach for your phone and taking your attention from driving as well as switch off of navigation moving your attention from driving, this is a clear definition of distraction and not serving the purpose it was created for which is also been confirmed by an independent shop. I reached out to GM. They said there was no recalls. And there is no service light. P.s.I just found out that I could make a complaint here so I do not have any of my old documentation. I just went to the dealership this morning to try and get some help and I had no luck. They would not be helpful at all. They just want to sign me up for a service meeting and charge me another $500 to look at it only to tell me they can’t order me a wearing harness again.
