POWER TRAIN
Over the past 4–6 months, the transmission in my 2023 Chevrolet Silverado 1500 has repeatedly failed in a way that creates a serious safety hazard. On multiple occasions while driving at highway speeds, the transmission has locked up the rear end, causing a sudden and violent loss of control. These incidents nearly resulted in collisions and could have caused serious injury or death. The truck will no longer shift at all and is now completely inoperable. These failures happen without warning and present a severe risk of total loss of vehicle control. Date(s) of Incident: Multiple occurrences between approximately March 2025 and August 2025 (exact dates unknown). Dealer / Manufacturer Response: I contacted Chevrolet Customer Care and multiple Chevrolet dealerships in my area (including John Megel Chevrolet, Dawsonville, GA). My most recent case was closed without resolution. I have been denied a loaner or reimbursement for a rental vehicle, and I have been told that the repair could take at least a month before even being assessed, with additional delays for parts. Consequence: This is not only a serious safety hazard but also a severe financial and employment hardship. I rely on this truck for my job, and without it, I cannot work. I am now three months behind on my truck payments and other bills, and I am on the verge of losing my job because I have no transportation. GM’s failure to repair or provide alternate transportation has left me stranded, financially unstable, and at risk of unemployment — all while the vehicle remains under an extended warranty. Request to NHTSA: I am requesting that NHTSA investigate whether this defect is part of a wider safety issue affecting 2023 Chevrolet Silverado 1500 transmissions and determine if a safety recall is warranted.

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

Component or system failed- Lifter in the 4th cylinder - 4 different times. Safety - Driving down the interstate, when the lifter goes out the truck slows down in limp mode and causes safety issues for myself and vehicles around me. Problem has been fixed 4 times, now waiting on a BRAND-NEW MOTOR that is on backorder for the foreseeable future. NO WARNINGS WHATSOEVER.

POWER TRAIN, ELECTRICAL SYSTEM
Vehicle: 2021 Chevrolet Silverado 1500, 3.0L LM2 Turbo Diesel Mileage at most recent failure at 106k miles Complaint Narrative This vehicle has experienced repeated, serious defects affecting engine, transmission, emissions system, and safety recall performance. Despite numerous repair attempts over three years, the problems remain unresolved and the vehicle is currently undriveable and held by the dealership (since August 17, 2025). Key safety concerns: Transmission failure: Transmission catastrophically failed at 78,942 miles due to excessive metal contamination, requiring full replacement. Transmission issues have persisted even after replacement. Recall N24254440 (rear wheel lock-up): Dealer attempted recall repairs multiple times in 2025 but failed due to programming errors. Recall remains incomplete and unresolved. Hard starting / reduced power: Vehicle intermittently fails to start or loses propulsion, creating risk of stalling in intersections or traffic. Engine/emissions failures: Multiple check engine events with NOx sensors, exhaust differential pressure sensors, and coolant flow valve failures. Current status: Vehicle has been in dealer custody since Aug 17, 2025, with no completion date. Dealer reports unresolved oil leak, check valve/box sensor replacement pending, and open recall not fixed. The cumulative history shows systemic defects across powertrain and emissions systems, ongoing safety recall failures, and lack of durable repairs. I am providing all invoices, videos, and documentation upon request. --- Chronological Service Timeline Invoice #Mileage (in/out)DateReported Issue / Repair Attempt 33432337,290 → 37,62607/11/22 – 07/30/22Check engine light.

AIR BAGS
Just few minutes ago around 5:45 PM, Monday, September 8th 2025. I started my engine with the remote start in my drive way. After about 30 seconds there was a series of 3 or 4 violent explosions each with a 1 or two second interval. The driver side, passenger side and both side air bags deployed fracturing my windshield and causing other potential internal damage to the passenger compartment. I feel very fortunate that I wasn't seated in the vehicle at the time as I'm sure I could have been severely injured or potentially killed. I had taken the car in for an air-bag recall a couple of years ago at Good Chevrolet in Renton, WA.

SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While towing a camping trailer, the brakes for the trailer kept issuing a warning saying "connected" then "not connected - check trailer brake wiring". Then "trailer brake not connected". After a while the brake system stopped working entirely. The 30 amp fuse that controls the trailer braking system blows out. This fuse is not a common fuse and not available at some auto parts stores (not really convenient while towing away from home). Evidently there is a problem with the brake control module that is factory installed. The module does not like the charging system on the trailer battery. I have spent hundreds of dollars and many hours in different shops trying to trace down this problem. It is very unsafe to have the trailer brakes not work while driving. This faulty module needs to be recalled. Part # 23306694

AIR BAGS
on 7SEP 2025 @ 1100 While backing out of my driveway in my 2007 Chevy 3500, the vehicle’s airbag suddenly and unexpectedly deployed without any collision. The airbag struck me in the chest and left forearm, causing immediate injury. Since the incident, I have been experiencing chest pain and shortness of breath. Prior to this incident, I had taken my truck in for service due to concerns about the airbag recall affecting certain GM vehicles. At that time, I was informed by the dealership that my truck was not included in the recall year range. Despite this, the airbag has now malfunctioned in a way that has caused me injury. I attempted to contact the National Highway Traffic Safety Administration (NHTSA) and the GM/Chevy Safety Office to report the matter, but both offices were closed at the time.

When towing a trailer, the trailer brakes will disconnect when applying medium to hard brake. This is when the brakes on the trailer are needed the most. The trailer lights still work when the brakes controller disconnects them. There was a recall on the 2024 Chevrolet HD trucks to "fix" this.

POWER TRAIN
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

ENGINE
At 5,750 mi. the 6.2 gas engine seized due to connecting rod bearings. The dealer replaced the engine, cooling system and oil cooling system under warranty with a similar engine. I am of the opinion that it could have been at least partly due to the low viscosity motor oil that the manufacturer insists upon to maintain the factory warranty, 0-W20 synthetic, along with a poorly engineered fuel management system. Also, once the vehicle was stopped and put into park, the electronically controlled transmission refused to change gears, to be put into neutral, in order to be pushed out of traffic and on to a tow vehicle, it had to be dragged. The vehicle is extremely unreliable and a danger to the public.

The transmission started to shutter at 94,000 miles. Gwatney Chevrolet quoted $7,500 for a new transmission replacement. Had an in independent shop quote $4,670 for a reman transmission. I have only towed 2,000 lbs at a time in the past. This is the 1st time towing a 6,000lbs camper. It was only driven 800 miles with the camper in tow. The vehicle only has less than 95,000 miles and my transmission is shuttering and has metal shavings in the fluid. Needing a replacement at this time frame and mileage is ridiculous.

FUEL/PROPULSION SYSTEM
Code p0307 misfire on cylinder 7. Have gotten code 3 times in last month. Lights on dash and reduced power. Less than 50k miles when first occurred. Turn off and back on all lights gone except for engine light which goes off in a day then runs fine. Dealer quoted $3k+ to replace injectors. $60k+ for a new vehicle it should last more than 2 years and 50k miles. 5 yr 60k mile engine and power train warranty but they pick and choose what components to cover. After looking online I see many owners with same issues. Some with hardly any miles. Other recalls done with different motor sizes. HELP!!!

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, ENGINE
Truck experienced reduce power mode. Took to have codes ran and it showed 24 separate codes when engine light comes on. While riding down the road, truck will go into reduce power mode, shift automatically into 4x4, and several other notifications will appear. Taking to dealership and was told the electrical wiring harness was shorting out causing this issue. Cost around $700 for repair, happened one month later, took it back and no charge for the 2nd time. It is currently in reduced power now. Dealership stated to replace the wiring harness would cost over $3,000. Dealership stated this was a manufactures defect, but no recall was issued so all cost is on the owner.

Transmission failure, I had to have the transmission replaced and no longer have it for inspection. I was on a one lane highway in Franconia NH with guardrails on each side, and no phone reception. Traffic was trying to get by me including tractor trailers, we were horrified and couldn't get out. these 6L80 transmission in the Chevy Silverado, come to find out, have been failing for a long time. 2 of my friends lost there's also, all of us were between 100k-115K miles. The transmission shop I went to, and others I called said they can't believe there was never a recall, they get many of them. Zero warning, just quit. I take exception care of my vehicles regarding maintenance, always early, these are to expensive to repair when your on a retired budget.
