BACK OVER PREVENTION: WARNINGS, ELECTRICAL SYSTEM
My 2023 Chevrolet Suburban developed a "Service Driver Assist System" warning, and both the front and rear parking assistance systems stopped functioning. When approaching objects at low speeds in Drive or Reverse, the vehicle did not provide the expected parking distance warnings. I took the vehicle to an authorized Chevrolet dealership on October 22, 2026. The dealership initially attributed the problem to a low 12-volt battery and recommended replacing it. I authorized installation of a new ACDelco AGM battery. The dealer tested the charging system at 13.5 volts. However, after the battery replacement, the "Service Driver Assist System" warning remained, and the parking sensors still did not function. The service advisor initially indicated that the warning might take 12–24 hours to disappear. I returned to the dealership because the problem persisted after waited for a weekend. The parking assistance system remains inoperative, reducing the driver's ability to receive proximity warnings when maneuvering or parking near obstacles, pedestrians, or other vehicles. I am reporting this incident because the driver-assistance warning and parking sensor failure persisted after the initial repair. The underlying cause of the sensor damage has not been established.

ENGINE, UNKNOWN OR OTHER
In the evening I was driving home locally and noticed a slight lurch in the car when coming to a complete stop at the stoplight. From there I proceeded into my neighborhood. There was a sudden and very loud bang sound like metal and an explosion. Immediately the engine failed and my vehicle stopped in the middle of the road. I also smelled a lot of gasoline. I was unable to shift the vehicle into neutral to move it off the road. I called a tow through AAA. Luckily I was not on the freeway or a busy road when this happened as it could have caused an accident. My vehicle is at a certified chevrolet service center where they confirmed their opinion is the timing chain snapped and destroyed my engine. They are recommending a complete motor replacement. The vehicle is available for inspection upon request. This vehicle is the same year make and model as a previous recall in 2025 however I am curious as to why my VIN is not included in this recall.

SUSPENSION, STEERING, POWER TRAIN
Component: Steering & Suspension / Upper Ball Joint--Catastrophic Structural Failure: On [XXX], at highway speeds on [XXX], the left front wheel completely separated from the upper control arm due to an instantaneous upper ball joint failure. The left tire turned sideways, locking the steering system. The vehicle was equipped with factory stock suspension and GM 24-inch rims-Pre-Accident Diagnostic Negligence: The vehicle exhibited a severe front-end "thumping noise" within the warranty window. It was brought to Lucas Chevrolet on [XXX] (31,901 miles) and Burlington Chevrolet on [XXX] (with a "Service 4WD" light active). Both certified facilities failed to perform physical tear-downs or torque checks, releasing a hazardous vehicle. Burlington Chevrolet is currently ignoring all voicemails requesting my service records-Dangerous 20-Hour Roadside Abandonment: Chevrolet Roadside Assistance left the driver stranded on a live highway shoulder for 2.5 hours in rush-hour traffic and darkness. Due to unsafe conditions, the driver was forced to leave the vehicle for an unassisted tow. Because roadside repeatedly sent wrong equipment for a collapsed suspension, the vehicle sat overnight and was not delivered to the dealer until 21 hours later-Evidence Preservation Hazard: Dealership Director Bob called the consumer to explicitly direct them not to hire legal counsel. Following this call, the dealership unilaterally changed writing from a "Customer Satisfaction Guarantee" to a "Goodwill Repair" and Service Manager Denny DiRenzo levied a $150 core charge on the steering rack. This fee acts as a financial barrier to force the surrender and destruction of the physical evidence. GM is also refusing to inspect the remaining three ball joints. Investigate Manufacturing Defect: Cross-reference this structural collapse with active wheel hub bolt recalls, Wave the $150 core, investigate parts, buy back, create recall for hub bolts and upper control ar INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 5

ENGINE, POWER TRAIN
I was driving 60 miles per hour on the 101 highway around 8:30AM and a couple error messages suddenly appeared on my dash - one regarding traction control and the other regarding ESC. My engine light continuously flashed. I took the car into the dealership and they requested 3K to take apart the engine to figure out the issue. They now state that the number four cylinder lifters and the camshaft are pitted and thus the cylinder walls of the engine are scratched and thus the cylinder block can not be reused and needs to be replaced. They are requesting an additional 17,000 to replace the engine entirely. There was a recall on this vehicle for March 2021-2024 vehicles. Mine is just outside that recall being manufactured in January or Feburary 2021. Clearly, my issue is suffering the same problem from this recall.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
Persistent, intermittent total audio cutout disabling critical crash avoidance alerts. Failure Summary & Safety Impact: The vehicle experiences intermittent, complete failures of the audio system across all sources. When this failure occurs, all audible safety warning chimes are completely silenced—including Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, and Park Assist. This places occupants and other road users at immediate safety risk, as the driver receives no audible warning prior to an impending crash or hazard. Diagnostics & History: The issue first was brought to an authorized Chevrolet dealership for inspection and repair multiple times (first on April 29, 2026) and has not been remedied. They even replaced the radio system (through which all audio is routed) and this did not fix the issue. The vehicle remains in its original condition and is available for inspection upon request. There were no dashboard warning lamps or error messages displayed prior to or during the failure.

POWER TRAIN
My 2023 Chevrolet Suburban RST equipped with the 6.2L V8 engine has developed serious transmission and drivetrain issues following an engine replacement performed under a GM recall approximately one year ago. Shortly after the engine replacement, the transmission began exhibiting unusual shifting behavior. The dealership advised that the transmission needed to reset or relearn its shifting patterns. However, approximately 10,000 miles later, the problems have continued and become increasingly concerning.The vehicle now shifts extremely hard when engaging Drive or Reverse and experiences harsh, abrupt shifts while driving. More concerning, the rear wheels have appeared to lock up unexpectedly on multiple occasions at low speeds, creating a dangerous situation where the driver could lose control of the vehicle or be struck by another vehicle. I reported these problems to the Chevrolet dealership, but I was informed that they could not reproduce the issue or identify any diagnostic trouble codes. Despite these serious symptoms, the underlying problem remains unresolved. I am concerned that this may be a transmission, torque converter, transmission control module, or drivetrain defect affecting other GM vehicles equipped with similar powertrains. I am requesting that NHTSA investigate these potentially dangerous failures, particularly the unexpected drivetrain locking and severe transmission engagement issues, before they result in a serious accident or injury.

ENGINE
On 5/28/25 the vehicle was on the interstate and presented a check engine light. Shortly after getting off the interstate the vehicle limited speed. This was taken to the dealership and they replaced the #6 injector. This vehicle was identified as having a left bank tick on 11/18/22 by the dealership but could not be duplicated by the mechanic. On 5.8.23 the #8 injector was replaced due to code and the vehicle vibrating at low RPM and at stops both in park and in drive. On 5/28/25 the #6 injector was replaced due to code and rough idle. They also replaced all spark plugs. On 12/29/25 the #8 injector was replaced again due to rough idle and code. On 6.23.26 the vehicle was again taken to the dealership due to rough idle. Nothing was done. On 8/18/26 the vehicle was taken to the dealer for a rough idle again. The dealer found no codes but wanted to change the oil to troubleshoot. I allowed it telling them changing the oil would not correct the misfire. Even though the misfire was present after the oil change the shop foreman would not troubleshoot further due to no code displayed. I purchased a scanner and found 81 misfires on cylinder 7 for the current cycle.

STEERING
This has almost caused us to get in an accident several times now. While driving and taking a curve or while gradually turning, the power steering failed. The steering wheel was extremely difficult to turn, and my wife could barely turn it. The message “Steering Assist Reduced – Drive with Care” was displayed. When we pulled over and turned off the engine, and then later re-started the Suburban, the power steering worked again. The dealer conducted a diagnostic on it and could not find the problem at first. They later said the Power Steering Gear needed to be replaced. This is a very dangerous problem.

VEHICLE SPEED CONTROL
As I was driving on the Highway. My speed was approximately 65 MPH. The suburban slowed itself down and flashed on the driver screen "slow down/reduced acceleration". I was driving with my family in the car on the highway. The car forcing a slow down like that could have caused an accident that could have killed my 3 year old or my 9 year old. We drove the car home in fear after reading online that the rear tires could force stop on us. We immediately did an at home diagnostic on the vehicle and were given the following codes: P0700, P0747. We have taken the vehicle to the nearest Chevrolet Dealership and had it diagnosed. We were called today and told that the valve body needs replacement. There were no prior warnings or other symptoms of the problem prior to the failure. We've had it serviced at this dealership, had any recalls checked at this dealership and no warnings had been provided.

SUSPENSION, STEERING, WHEELS
Component Affected: Suspension / Steering / Wheels / Front Hub Assembly Description of the Safety Defect & Incident: Proactively brought the vehicle to two separate authorized Chevrolet dealerships due to a severe thumping noise when turning the steering wheel. I explicitly stated to service staff that the vehicle felt unstable and unsafe to drive. Both dealerships performed inspections, stated they found no issues, and released the vehicle back to me. Shortly thereafter, while driving at full highway speed during rush hour, the front-end suspension/hub assembly suffered a catastrophic structural failure. The front driver-side wheel completely turned sideways and broke off, causing the vehicle to drop directly onto the pavement and skid violently across the highway. I narrowly avoided a multi-vehicle collision and managed to slide the vehicle to the shoulder. The wheel hub assembly completely separated from the steering/suspension structure, rendering the vehicle totally disabled. This failure matches the catastrophic hazards associated with recent GM front-wheel hub bolt relaxation and separation safety notices.

ENGINE, SERVICE BRAKES, FUEL/PROPULSION SYSTEM
On August 7, 2026, while driving a rental vehicle in the Denver, Colorado area with my family, including two young children, the vehicle unexpectedly lost engine power while traveling downhill. The engine shut off, resulting in a significant reduction in brake assistance and creating an extremely dangerous situation. We were able to bring the vehicle to a stop without a collision or injury. After restarting the vehicle, the check-engine light illuminated. The vehicle was no longer considered safe to operate and ultimately required towing by the rental operator. The exact mechanical cause is UNKNOWN. I do not know whether the vehicle was subsequently inspected or repaired by a qualified service center, and I do not have access to its diagnostic or maintenance records. After the incident, I discovered that another renter had reported a substantially similar failure involving the same vehicle approximately one week earlier, including engine problems and a check-engine warning. I have since discovered an additional report of an engine-related issue involving this vehicle after my rental. Despite these recurring reports, the vehicle appears to remain available for rental to the public. I am concerned that this vehicle has a recurring, potentially unresolved defect involving engine shutdown or loss of power while driving. Such a failure creates a serious collision risk, particularly on hills, at highway speeds, or in traffic. I request that NHTSA investigate whether this vehicle's repeated failures indicate a broader engine, electrical, or powertrain safety defect. The vehicle remains in the possession or control of the rental operator and may be available for inspection. I can provide supporting documentation of the reported incidents.

ENGINE
Driving our 2024 Suburban, 6.2 L engine, on a 2-lane highway in southern Utah, traveling on cruise control at 70 mph, felt 2 hesitations (jerking movement), and turned off cruise control. Immediately after, heard knocking/thumping sound in the front of the vehicle, followed by a whining sound that got louder. Immediately found a turn-off from the highway, pulled in, and engine died while vehicle was still in motion. Attempted starting again and would not start. People stopped to help us and tried to jump vehicle without success. Suburban was towed to a Chevy dealership and we were told the Suburban's engine seized. In researching this issue, we came across NHTSA's investigation case EA26005. Our VIN does not fall in to this recall.

ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, POWER TRAIN
I was driving south on Highway 395 with 2 of my friends on our way home from vacation, which is a 2 lane road in the mountains. About 45 miles north of Victorville, CA. As I was accelerating, my vehicle all of a sudden dropped adaptive cruise control, the engine light started blinking, traction control errored, and I got a service ESC message on the dash. I let off the gas a little and everything seemed fine but when I reapplied pressure to the gas pedal the engine started making a loud ticking sound and had barely any propulsion. I had to keep going and was luckily able to find a safe place to pull off the road (which had many blind curves and minimal shoulder space along the highway). Had there not been a safe place to pull over before the engine completely died we could have been hit by any of the many semi trucks traveling on that road. After waiting 2 hours for a tow truck and having the vehicle towed to the Chevrolet dealer in Victorville, I was provided a small SUV rental vehicle to drive the remaining 150 miles home while I left my 2023 Suburban High Country for them to disassemble. When I called the next day they verified there was a Rod Bearing Failure inside the engine and they were submitting to GM for engine replacement. There were NO symptoms before the engine failure happened.

POWER TRAIN
Transmission / Electronic Shifter Control While attempting to operate my 2023 Chevrolet Suburban, the vehicle suddenly suffered a complete transmission shift lockout, displaying a critical driver alert on the dashboard stating: "Conditions Not Correct for Shifting." The vehicle actively blocked and refused engagement into Reverse gear. A diagnostic scan revealed (P0776) transmission solenoid and hydraulic control codes, and the Chevrolet owner's application triggered a "Service Engine/Transmission" warning. This issue is identical to the widespread, known manufacturing defect involving premature wear of the 10-speed transmission control valve body. General Motors has already acknowledged this severe defect by issuing a major safety recall and extended warranty program (Campaign N242454440 / N242454441) due to internal fluid pressure drops that can cause sudden rear-wheel lockup or an abrupt loss of motive power. Safety Hazard: The sudden and unpredictable failure of the electronic shifter and transmission control modules to authorize or maintain gears poses an extreme, unreasonable safety hazard. An unexpected loss of gear engagement—or a sudden command lockout while operating the vehicle in a roadway, intersection, or active traffic pattern—leaves the driver completely unable to maneuver out of harm's way, drastically increasing the risk of a severe rear-end or side-impact collision. Request for Action: Although General Motors currently limits their safety recall and special coverage campaigns for this valve body defect to the 2020–2022 model years, my 2023 model utilizes the exact same transmission architecture and is exhibiting the identical component failure. I am urging the NHTSA to initiate an Engineering Analysis / Recall Query to force General Motors to expand their safety recall parameters to include 2023 VINs before these component failures result in catastrophic highway accidents or injuries.

Tuesday October 6th, 2026, I dropped my 2 children off at school and was driving on the highway to work through heavy traffic when I had a suddenly loud knocking coming from my car, transmission not wanting to shift properly, high rpm’s for extended periods of time. I was able to safely make it to the dealership with about 10 minutes, where it was determined L87 engine failure had occurred. I am sickened that this vehicle is advertised as a family vehicle, knowing the engine failure issues!
