ENGINE
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?

ENGINE, POWER TRAIN
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
My 2018 Silverado z71crew cab LT , 5.3L engine was having issues with hold Freon in AC unit. We took to dealer to be fixed in June 2025. They added Freon and it was running good for a week then once again blew but no cold air. So took back second time 7/3/25 and they started the die test and machine went down in middle of doing it. So could not finish fixing . We took back on 07/20/25 and they completed the test needed condenser . So few days later we took to our local mechanic to have the condenser replaced and all is well with the AC unit now. Everything was fine from mid July 2025 till Oct 14 th 2025 , when it started shaking and was running rough and engine light was on so I had it checked for codes to see what it needed. Came back as bad injector. So we took to local mechanic to have injector replaced and tuneup and coils replaced . After this was completed was running much rougher then before we even had that injector and tuneup done. So mechanic suggested for him to keep it and let him dive deeper into what was wrong and why it was running rougher than before, so we let him do that.. after two days, he came back and told us that there was a crack in the engine and that is why it was running rough and that it probably was going to have an engine failure and might be and must be replaced. So I looked up my VIN number to see if there’s any recalls for my particular truck and engine size which is a 5.3 L and it doesn’t show my particular truck but it does show my year of a Silverado and the 3.6 L engine has had the same issues so I was wondering if this recall should be extended to the 5.3 L 2018 seems to be the same problem with the engine block.

SERVICE BRAKES
When attempting to stop, the brakes were rock hard and would barley compress. Almost crashed into the car in front of me. Brake booster was replaced a month ago by dealer, but still is losing vacuum. No codes are being thrown, so any reasonable driver would assume everything is fine with the vehicle. It is going to get someone killed.

ELECTRICAL SYSTEM, STEERING, VEHICLE SPEED CONTROL
Truck was intermittently losing power steering and shutting off/reseting itself. Was a loss of electrical and was throwing Stabilitrak Service warning. Would not stay on due to truck resetting itself but loss of power happened typically when I was in parking lot or driveway. Could have easily been on the highway which could have been deadly. Dealership found that the battery cables and module were not getting enough power to truck. Replaced these and it seems okay now. Total cost was ~$1200. I see several recalls for battery cable issues but nothing pulling on my 2018 Chevrolet Silverado 1500 LTZ crew cab.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
To Whom It May Concern, Below is my support statement regarding recurring safety and reliability issues observed in the vehicle over an extended period: 1. Sensor Malfunction and Resulting Damage The front and rear proximity sensors exhibit repeated failures. During reversing, the system issues false warnings when no obstruction is present. Conversely, while driving forward, the system fails to provide warnings when approaching walls, sidewalks, or other fixed objects. These failures have directly contributed to multiple instances of exterior damage, including impact with hard surfaces, as well as damage to tires and rims. 2. Warning System Deficiencies The engine warning system has proven unreliable. Significant oil leaks occurred without any corresponding check engine notification. On separate occasions, the check engine light illuminated briefly before extinguishing without resolution. 3. Diagnostic Inconsistencies Independent diagnostic inspections identified multiple ECM fault codes. However, upon subsequent service visits, these codes were cleared or dismissed without adequate explanation, creating uncertainty regarding the vehicle’s underlying condition. 4. Excessive Repair History Despite Limited Use Over the past several years, the vehicle has required multiple costly repairs despite being operated only for routine transportation. It has not been utilized in off-road conditions or to its full 4x4 capacity, yet has demonstrated significant and repeated mechanical deficiencies. The issues experienced indicate systemic failures in critical safety systems, monitoring functions, and diagnostic reliability. These unresolved defects have resulted in repeated safety risks, physical damage, and disproportionate maintenance requirements
