2016 Chevrolet Silverado 1500

Vehicle: 2016 Chevrolet Silverado 1500 Component: Powertrain – Automatic Transmission (8L90) Manufacturer: General Motors (Chevrolet) I am submitting this complaint regarding recurring transmission problems with my 2016 Chevrolet Silverado 1500 equipped with the GM 8L90 eight-speed automatic transmission. I am concerned about the vehicle's inconsistent shifting behavior, the repeated failure to resolve these issues through service, and the potential safety implications of unpredictable transmission performance. My truck has been taken into the shop multiple times because of transmission-related concerns, including hard shifting, intermittent and inconsistent shifting, and transmission shudder. Despite these repeated service visits, the problems have continued. During one of the repair visits, the transmission wiring harness was replaced. However, the shifting concerns persisted. I was subsequently told by the service personnel that the hard shifting and intermittent shifting were “just how the transmissions on these are.” I do not consider this an acceptable resolution to a recurring mechanical and drivability concern. I was also informed that GM introduced updated transmission fluid intended to help address the transmission shudder, but that I would have to pay for the fluid service myself. I have been left facing additional expenses for the revised fluid, a potential torque converter replacement, and other transmission upgrades despite the repeated repair attempts and the continued existence of these problems. My primary concern is the transmission's inconsistent operation and the possibility that unexpected or severe shifting behavior could affect the driver's ability to control the vehicle safely in certain driving situations. Depending on the circumstances, unpredictable shifting, hesitation, or abrupt engagement could create a hazardous situation when accelerating, merging into traffic, navigating intersections, or driving in congested condition

"While driving, the vehicle experienced a sudden and complete loss of propulsion/acceleration due to internal failure of the 6L80 6-speed automatic transmission. The failure occurred without prior warning, creating an immediate highway safety hazard by leaving the vehicle unable to maintain speed in traffic. A professional mechanic diagnosed the issue as a catastrophic torque converter failure that contaminated the entire transmission system with metal debris, requiring a complete out-of-pocket rebuild." This resulted in having to pay $4,800 plus tax in such a rough economy.

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated that after parking and turning off the vehicle, the three rear brake lights remained illuminated overnight, causing the battery to drain. The contact had to disconnect the battery terminals to prevent the battery from draining. The vehicle was taken to the local dealer and mechanic on several occasions, but the cause of the failure was not yet determined. The failure mileage was 30,000.

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated that while attempting to make a left turn from a complete stop, the vehicle lost motive power while depressing the accelerator pedal and was stranded in the middle of traffic. No warning lights illuminated. The vehicle was placed in neutral(N) and pushed to the shoulder of the road. The contact's husband arrived at the scene and restarted the vehicle; however, while driving at low speeds, the failure recurred. The vehicle was towed to a dealer, where it was diagnosed with metal shavings in the transmission. The dealer informed the contact that the transmission needed to be replaced. The vehicle was not repaired due to the repair costs. The check engine warning light illuminated. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

I had noticed that my a/c was not cooling due to refrigerant loss. went to dealer and was told that I needed a new condenser and that my original was out of warranty & no recall was in effect. I was charged $1600.00 after the replacement was installed. I asked to see my original condenser & was directed behind the shop & low & behold there was a pile of 30 condensers exactly identical to mine

This truck is a 1500 Silverado custom with extended tail. There was a loud sound as if something happened , I moved to the shoulder and there was nothing visibly wrong. All tires had air in them, continued driving but did noticed a difference when I would back or turned to the right. Then days later one of my tires sort of was ruptured from the side of the tire and had to change tire. I put the spare and it is when I notice the bushing on both arms that hold the front wheels was loose. Looked for recalls and this model Chevrolet 1500 has a recall for front suspension arm bushing giving out and it is exactly what happened to my truck. The loud sound must have been one of them and then since most of the weight was put on the other bushing, made the tire give out and both bushings are not broken or torned so the bolt that holds arm and bushing is movable and loose, not holding the wheel the right way

For the past 2 years ive been having issues of losing power steering. Lots of parts and modules have been replaced out of pocket. Still not fixed. When it goes out it can be out for days to weeks and is extremely hard to steer. Its gone out or come back in during a turn which is very problematic and unsafe. I always get the same dash message, "service power steering drive with care". The dealership is aware and has seen the malfunctioning steering. So far the rack and pinion gear box has been replaced at $2700, then it was a terminal resistor that was replaced for $2,100, and several other trips in costing more money just to get the steering fixed but technicians have been unsuccessful so far despite their best efforts.
