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.

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

No check engine light come on until continued driving over 15-20 miles. Transmission slams into second gear when taking off or when stopping it may or may not downshift into first causing safety issues when in traffic. Possible electrical error or clutch inside transmission. On this model it is a sealed transmission so no way of identifying if metal shavings come out with a transmission flush. The issue only happens when vehicle is at temperature, if under and still cool drives perfect but as soon as it hits the temperature of 210 it slams very ugly.

1. The components that failed were the transmission because the vehicle was driving and continued to slow down until it came to a complete stop gradually, and had to be pushed home. And also, there was an issue with the doors unlocking on their own and all windows rolling down by themselves. 2. The safety risk was the issues that happened without any knowledge of any issues at all with the vehicle. And the vehicle could have stopped on the highway, and another vehicle could have run into it, and it could have been a very bad incident. And with the doors unlocking and the windows rolling on their own could be exposed to unsafe environments and possibly theft of the vehicle or harm to the occupants. 3. Had a scan done, which showed the issues that were going on with the vehicle 4. I haven't had a chance to have it taken to the manufacturer because it broke down, and I was waiting for some help to get these issues repaired from the manufacturer. And needed from ACC. 5. There wasn't no indicators or lights on when this happened? I was told by a coworker about the windows being down, and with further investigations, I found the doors were unlocked as well, which was done automatically without my control.

I purchased my truck in December 2018 which is a 2018 Chevrolet Silverado 1500 4x4 crew cab automatic from Servco Chevrolet Dealership in Waipahu, Hawaii and making monthly payments for my truck February of 2019 truck runs good and purchased the warranty also had my oil and service changed when time is due which I always kept up. [XXX] and mileage was 40k while leaving work to go home at a stop light was red once turned green I pushed pedal to go and truck just changed noise tone started to run like rough idle, loud tapping noise coming from the engine, shaking and check engine light came on almost causing me to get into an accident. I pulled on the side and checked what was going on and heard the tapping noise from the motor. So I made an appointment with service department with Servco Chevrolet Dealership where i bought my truck from and spoke with the service tech for my truck to go in for repairs due to issue. It took 2 to 3 weeks for repairs to be complete and service tech informed me that I'm not the only person to have that issue which had to do with the lifters and camshaft with these motors but GM never came out with any recalls due to how much people has the same motors with the same issue. So luckily it was still covered under warranty but said the problem might come back and would just replace the faulty lifters and camshaft. So in August of 2023 my truck has the same issue but wasn't covered under warranty anymore and mileage is 61k and missed the warranty repairs that was for the lifters which I got it scanned cause check engine light and same issue and code was P0016. So I called Servco Chevrolet dealership in waipahu again and spoke with the service technician which he told me I just missed the coverage of the warranty repair and only way to get it fixed I would have to bring it back for them to scan and roughly would range from 4k to 8k to get it fixed. So my truck is parked in my garage and hasn't been moved but paying for truck. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

10 miles from home on [XXX] after Thanksgiving with my children sleeping at [XXX] in snowy cold weather, my engine began to fail. Power was limited on hills and the check engine light would come on and go back off when on flat or downhill. The next morning I took my truck to the dealer that I purchased it from where I was told the lifters had failed and I need a new engine. 1000 miles after I replaced my engine my transmission failed completely requiring a transmission replacement. Immediately upon picking up the vehicle and going down a long hill in the area, engine breaking turned on as expected but as the truck tried to slow itself, after 2 or 3 downshifts, the transmission began making a loud grinding sound and while still going close to 50 MPH, the speedometer showed 10-15 MPH and the tach dropped to idle. The transmission was decoupled from the motor. When gas was reapplied it seemed to make the connection again and resume normal driving. I called the dealership whose techs did not believe me and told me that I could 'turn off' the engine breaking feature. The situation continued to worsen each drive and it would do it more often. This was unacceptable and they finally had a tech ride with me to experience it and immediately agreed there was an issue and reordered another transmission. The third transmission did not fix the issue and was experienced immediately. They are now guessing how to fix the issue telling me I have to replace the transfer case out of my pocket with no diagnosis, not sure what is causing it and have not fixed the problem. Videos would not fit in upload due to size. Videos show speedometer failure. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The following Recalls were found on Kelly bluebook, that matched the issues I have been having with my vehicle perfectly. When calling the recall center, they stated my vehicle year 2018 Chevy Silverado and serial number were not listed for this but it's the exact diagnosis of what I'm experiencing. The Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash. As the vacuum level drops, the brake assists decrease, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash. What component or system failed or malfunctioned, and is it available for inspection upon request? The brakes inflate on their own as if someone is pressing them down while driving. The vehicle begins to jerk horribly causing the inability to steer or maintain control of the vehicle or the ability to stop. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes How was your safety or the safety of others put at risk? This is very dangerous. I have no control over the speed of the vehicle or if the brakes will fail, or if the brakes will burn up due to fighting with the accelerator while driving. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, the manufacturer inspected it and stated they could fix the issues, paid but then the same malfunction kept happening even after payment and supposedly being fixed. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None related to the issues, Stabilitrak warning and then random hill assist to inflate the brake vacuum

P1. On or about Feb 9, Power Train transmission, Modular’s. While traveling about 40mph the truck shifted suddenly to low gear, and the water pump blew resulting in steam or smoke from engine hood. Automatic shifting was not possible, after slowing to 5-10 mph check if mauls shifting was an option. All gears L1 L2…were replaced with ‘L’. P2 March 2023 to presented 2024, the vehicle will vibrate and shake. More like a shimming. This happens what seems to be every .5 to 1.0 mile. P3 March 2023 The Transmission issue listed in para 1 happen exactly as describe above. Except the water pump was fine. On or about June 2021 The Transmission issue listed in para 3 happen exactly as describe above. I TOOK TRUCK TO HENDERSON CHEVROLET in Henderson , NV and reported the transmission sudden shift to low AND how the truck slams into gear when leaving a stop sign light. It feels like someone hit the back of the truck. Jerks forward. Service RESULT: that’s normal for the truck. October 2019, took truck to back to Circle Chevy / Hyundai in Shrewsbury NJ regarding the slamming and jerky transmission. RESULT: it’s normal or it didn’t do it while in service road test. I just bought the truck 1 month earlier from CIRCLE CHEVY of SHREWSBURY NJ. Regarding the most recent trans issue of Feb 2024, the power train went out of warranty in August. The issues should have been fixed when odometer was between 000064 to 60000 or Aug 2024. This truck is unsafe and sudden shift to low gear can cause the truck to get into accident

I am not paying for it to be fixed since it is an issue in the following year. I don;t think I should have to pay for a software issue. I just thought I would report it.
