2016 CHEVROLET SILVERADO 1500 reports

POWER TRAIN

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

POWER TRAIN

"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.

EXTERIOR LIGHTING

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.

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

SUSPENSION · AIR BAGS · WHEELS

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

STEERING

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.

STEERING · ELECTRICAL SYSTEM

Approximately one week ago I was driving at a safe speed on a two-lane highway. Suddenly, my steering wheel and truck jerked to the right. For 8-10 seconds a warning message was displayed "Power Steering ... Drive Carefully." I took the truck to my local dealership. They scanned for trouble codes. The technician said something about an interruption communicating with the electrical system. My service advisor took the truck on a 15-mile drive and had no problem. They scanned again and there were no trouble codes. The service advisor said they could not fix the problem if they did not know the cause of the problem. I left the dealership. Since then, I have had 4 more incidents. Once the warning message appeared again, but no jerk of the steering wheel or truck; once there was the same warning message and a jerk of the steering wheel and truck; and twice there were sudden jerks of the steering wheel and truck but no warning message. I have reported each of these incidents to the dealership. I also called Chevrolet Customer Assistance. I explained the problem and asked if they would assign a Field Service Engineer to assist the dealership. hey declined my request. Because I momentarily lose control of steering the truck, I fear for my safety and the safety of others.

ELECTRICAL SYSTEM · UNKNOWN OR OTHER · SERVICE BRAKES

Vehicle suffered a failure cascade of the brake booster vacuum pump system. During a low-speed bumper collision on July 4 and a boat ramp slide, the pedal triggered abnormal ABS-like pulsing as the computer tried to hydraulically compensate for dropping vacuum pressure. This resulted in truck front bumper damage and boat trailer fender damage. On July 10, total failure occurred in a drive-thru, rendering the pedal rock-hard and sopping mear impossible. All marked parts and logs are available for inspection. Onboard diagnostic data reveals the electronic brake control module has driven continuously without a master clear for 22,665 miles, locking the last system initialization to 78,468 miles. This continuous data loop proves code C0299-00 was actively visible in the history log during the subsequent dealer service visits. Instead of performing the hardware pump remedy under Recall N192268490 (NHTSA 19V650). At the Jan 24 dealer visit (78,482 mi), dealer applied a software update and charged out-of-pocket fees to clear symptoms. They also ignored subsequent communication regarding the billing discrepancy. Technicians completely neglected the history logs despite explicit complaints regarding low-speed ABS sensations, trailer brake messages, park assist, and brake assist warnings. The 2026 dealers (and 2024) falsified multipoint inspections stating brakes required NO service until after winter. Jan '26 dealer delayed further diagnostics until June '26. May '26 dealer ignored texts regarding a crooked steering wheel and unstable tracking after alignment service. The truck was intentionally misdiagnosed as functional to avoid the warranty period repair. This unaddressed mechanical failure caused a destructive system cascade requiring replacement of the vacuum pump, oil-contaminated vacuum lines lines, oil-saturated booster, master cylinder, glazed pads, warped rotors, fluid flush, tires from module drag, alongside the resulting bumper and trailer property damage.

On January 6, 2026., I was backing out of my son's driveway when I heard a loud pop, it sounded like a rock hitting the back window of my Silverado. I then discovered the driver's side of the back window shattered. Prior to backing out, I used the auto start to warm up my vehicle. I did some research and found there was a recall for this issue that was supposedly completed by Lithia Chevy of Helena on 6/29/2020. GM is refusing to replace the rear slider window stating there's no recall. I then reported the issue to GM Product Assistance claims it's do to wear/elements. See recall below. GM Program #N192265660 Status: Complete Description: Certain 2014-2019 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a power sliding rear window (RPO A48) may have areas of high electrical resistance on the rear defroster circuit. This could be caused, in part, by mechanical stress from opening and closing the rear power window, intrusion of debris, and use of the rear defroster. Over time, this condition could generate heat that could melt the areas surrounding the circuit. In rare instances, this heat could cause a non-propagating fire, increasing the risk of property damage or injury. This is the second time Lithia Chevy has claimed they completed a recall. On July 28, 2023, my brakes failed during a 200-mile trip to my hometown. After several days of battling with Chevy and General Motors I paid a private mechanic 100 to verify the vacuum pump had failed on my Silverado, Chevy finally fixed the issue on August 8, 2023. There was 47,781 miles on it at the time. See Repair Description below showing they supposedly completed the recall, the same day as the back window recall (6/29/2020). Repair Description Dealers will reprogram the electronic brake control module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. Recall Completed: 2020-06-29

The contact stated that the brake pedal failed to function properly and felt spongy while attempting to depress the brake pedal. The contact stated that the vehicle had previously received a brake system software update under an unknown recall, which was completed by the dealer. The vehicle was taken back to the dealer; however, the vehicle was not diagnosed or repaired. The contact was informed that the brake system software update might be performed another time. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 175,446.

I was a front seat passenger in a 2016 Chevrolet Silverado 1500 and was properly wearing my seatbelt at the time of the incident. The vehicle struck a deer, and during the collision, the passenger seatbelt failed to properly restrain me. I was thrown forward and struck the windshield. The seatbelt did not appear to lock or tighten as expected during impact. It is unknown whether the seatbelt pretensioner or airbag system activated properly. This created a serious safety risk, as the seatbelt did not perform its intended function of restraining the occupant during a crash. The vehicle was declared a total loss following the incident and is no longer available for inspection. The incident was documented through insurance and/or police reports. There were no known warning lights or prior indications of a problem with the seatbelt system before the crash. This failure resulted in occupant injury risk due to lack of proper restraint during the collision.

The truck engine light came on and was not able to be driven very far without stalling. Took it for repair and 2 valve lifters were bad. We had to pay for replacement ourselves. This happened at 41,786 miles. This happened again at 46,000 miles because of faulty GM parts and they needed to be replaced again. The parts were under warranty so there was no charge. This happened again at 59,000 miles and now both side lifters are bad and mechanic suggested engine replacement since he is sure this will happen again. Now it’s costing us 15,300 to repair it and GM/Chevrolet is not helping or do they care! First incident was in April 2023, second in November 2023 and now in December 2025.

I am reporting a manufacturing defect involving General Motors’ Active Fuel Management (AFM) system. In October 2024, my 2016 Chevrolet Silverado 1500 LT, at 96,000 miles, experienced a lifter collapse which caused sufficient wear to the camshaft that the engine needed to be replaced, which was performed. The malfunction indicator lamp turned on and the truck was driven an additional 2 miles to a safe location and subsequently towed to the repair shop. Before then, there had been no indication that a lifter had collapsed or that there was damage to the engine sufficient to warrant a replacement. In November 2025, I experienced another lifter collapse (on the replaced engine). While the mechanic recommended an engine replacement, the warranty company only authorized a replacement of the affected side cylinder head and lifter, which was performed. In February 2026, I experienced another lifter collapse, and the truck is currently being evaluated by a repair shop. These failures have occurred without warning and aligns with thousands of consumer complaints regarding AFM-related oil consumption, lifter collapse, and engine damage in GM vehicles. This is a known design defect that GM has tried to address through Technical Service Bulletins and engine redesigns, yet many consumers continue to experience premature failures at low mileage. This defect presents a safety and reliability concern, including loss of power while driving and significant financial burden to vehicle owners. I respectfully request that NHTSA investigate this ongoing defect.

ENGINE

I am writing about my recent engine failure on my 2016 Chevy Silverado High Country. This is a 4x4 with the 6.2L motor. My engine has failed at only 66,790 miles due to the lifter issue that seems to be common with these motors. I noticed a loud ticking from my motor that was getting worse. I took it into A1 Automotive Georgetown, TX. They advised me to contact a dealership for Warranty repair or replacement as they noted it was coming from the valves. I contacted Don Hewlett Chevrolet; they advised me due to the date of the truck being made in 2016 it is no longer covered in warranty and the advisor said they do not see engines with lifter issues. I did standard service with an oil and transmission change using the recommended 0W-20W oil. The next day the ticking was very bad and turned into what I would describe as ‘jack hammer’ noises. Then I lost power while driving and the dashboard lights came on. I got towed back to A1 Auto; they drained the oil and noticed a lot of metal fragments and advised me that theck engine will need to be replaced. The engine was removed and we found the pushrod on the passenger side was sticking out to the side of the rocker arm presumably due to a lifter issue. I now have a new engine with the ‘delete kit’ to remove the 4-cylinder shutoff that has been linked to lifter failures. This has been a very unnecessary expense for something that shouldn’t happen. The motor only having 66,790 miles and I am the only owner, I have always taken very good care of it, and even use only premium gas. I have gotten all the oil changes on time and most of them have been done by the dealership at Don Hewlett. Date of ticking inspection and oil change, A1 Auto – 12/16/2025 miles 66,766 Date of failure 12/17/2025 miles 66,790 Charges: •Towing $235 •Engine replacement $14,064.90 oEngine $8,375 oLabor $3,750 oInjectors $1042 oOil, Tax, misc. $897

This vehicle has experienced repeated and ongoing serious defects with the 8L90 Transmission Torque Converter. I took delivery of this vehicle on 17SEP2016 and since it has required multiple service appointments to address the issue. To date it has not been satisfactorily repaired. Despite repeated failed repair attempts the vehicle exhibits erratic transmission slipping, jerking, hesitation and surging under acceleration. These symptoms persist even after a most recent torque converter replacement (and subsequent re-replacement as outlined below). This creates a serious safety concern particularly when accelerating into traffic, merging and driving uphill, but also in low speed maneuvers such as navigating a parking lot. The vehicle often feels like it is misfiring under acceleration when trying to merge, then surges forward erratically. In parking lots at low speeds, the downshift of this transmission is so abrupt that it often causes the driver and passengers alike to believe that the vehicle has been hit from behind. The repair history started within 2 years/24K miles as follows: - 01FEB2018 @ 28140 - Drain flush and fill transmission for Shudder/Hard Down Shift - Diagnosed as Torque converter issue. This helped for a short period of time - 26JUN2019 @ 53445 Miles - Same issue - same diagnosis - same repair attempt - this was unsuccessful in anyway. - 12NOV2019 @ 60653 Miles - Same issue and diagnosis - Torque converter replaced - 31JUL2024 @134218 Miles - Same issue and diagnosis - Flush and fill recommended since extended warranty had expired - paid $300 for transmission fluid flush and fill - 15APR2025@145963 Miles - Same issue and diagnosis - Torque converter replaced for $2956 - there was no appreciable improvement - 08AUG2025@151182 Miles - Torque Converter replaced under warranty from 15APR2025 work - No appreciable improvement - 20AUG2025@151500 Miles - Same issue - Advised to replace entire transmission

Transmission shifts erratically, sometimes violently. It seems to shift through several gears within seconds. There is no warning lights or codes that appear. I was rolling in line to exit a parking lot, going less than a crawl, and transmission shifted. It sounded like I had been rear-ended and vehicle lunged forward. There was enough distance that I was able to avoid the vehicle that was in front of me.
