UNKNOWN OR OTHER
I am filing a complaint regarding my 2024 Chevrolet Blazer EV (VIN: [XXX] ) due to an unresolved defect and repeated unsuccessful repair attempts. My vehicle has been presented to the dealership on four separate occasions for the same recurring mechanical noise issue. Despite these repair attempts, the defect has not been corrected. In total, the vehicle has been out of service for approximately thirty cumulative days. After the most recent repair, the same issue has again returned. I now have video documentation of the recurring defect. Additionally, during one of the repair visits, I was provided a gas-powered rental vehicle and incurred out-of-pocket fuel expenses, despite owning an electric vehicle. General Motors has declined to offer reimbursement for these expenses. Due to repeated unsuccessful repair attempts and the amount of time the vehicle has been out of service, I have formally placed General Motors on notice under Michigan’s Lemon Law and am pursuing review for repurchase or replacement eligibility. I am requesting assistance from the Attorney General’s office in obtaining a fair resolution, including reimbursement for expenses incurred and proper resolution of the ongoing defect.

ENGINE
The 2021 GMC Blazer (and related Chevy Blazer models) is experiencing recurring radiator failures, often requiring multiple replacements within short timeframes. The radiator was replaced in March 2024 and in early 2025 I went for an oil change and complained of smelling coolant and asked if it could be checked and was told nothing was wrong. I was told again in November 2025 that it has a leak and went to have an oil change in February 7, 2026 and was reminded that the coolant was low and the radiator needs replacing when I was first told I did not believe it to be true as it has been replaced before and I asked that it be checked and was told nothing was wrong.

Radiator leak from the bottom left corner (driver side). Slow leak over time, no visible damage (per the service department), likely a manufacturing issue. Entire radiator required replacement.

On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.

EXTERIOR LIGHTING, ELECTRICAL SYSTEM
My bright lights do not go off when oncoming vehicles or vehicles in front of me are close and when they do dim they go on and off. People flash their brights at me causing me not to be able to sleep and this happens even when they turned off of auto. Another item of concern is that the car would lock and unlock and the interior lights would go on and off. This was fixed but it was a line under the front that was not soldered together at the manufacturer is what the Chevy dealership stated.

ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
Around 55,000 miles, my 2021 Chevrolet Blazer experienced a throttle body failure. The check engine light illuminated and the vehicle entered a reduced power/limp mode condition. Throttle response was significantly limited, and the vehicle could not accelerate normally. While the vehicle remained drivable, it took substantially longer to reach speed, which could pose a safety risk when merging into traffic or crossing intersections. Diagnostic trouble code P2101 (Throttle Actuator Position Performance) was present. A Chevrolet dealer confirmed an internal throttle body failure and replaced the throttle body assembly. This component is a critical engine control system, and failure could affect acceleration and vehicle control, posing a potential safety risk. The failure occurred well before expected service life and required a costly repair. The component has been replaced and is available for inspection upon request. I believe this may represent a premature defect and should be investigated for similar failures in other vehicles.?

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Contining with issue referenced in 11701484. This morning (1/28/26) when leaving my home, I backed out of my driveway. Once I put the car into drive, the forward collision warning went off and locked up my car. The brakes would not release and I could not move out of the way of oncoming traffic. I do not know what allowed the brakes to finally release. I changed over to 4x4, put it into park and back to drive. My car finally was then allowed to move.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
I have found multiple times that the Instrument Panel (IPC) display and the center Infotainment displays have gone dark while driving. This has put me in unsafe driving situations because I am unable to monitor my speed and other important information displayed on the dashboard, or to control critical safety controls such as headlights, and other ADAS safety controls. Several software updates have been installed by the dealership, but the problem has persisted, suggesting a hardware issue with the radio unit. The manufacture insist it is a software problem and that they are working on a solution. Declining to replace the radio under warranty, additionally, they want me to wait until a new update is released, and in the meantime, my bumper-to-bumper warranty is about to expire. I have found that the radio unit is the main control module for both displays, multiple ADAS controls, and Headlights, and it should be recalled, with the manufacturer extending the warranty or including the radio as a safety feature under the extended powertrain warranty.

SERVICE BRAKES
On December 22, 2025, I purchased a brand-new Chevrolet Blazer EV SS from a dealership located approximately 1 hour and 10 minutes away from my home. Immediately after leaving the dealership lot, I noticed a grinding / grunting noise coming from the vehicle. This was not a minor rattle or normal “new car” sound—this was an alarming mechanical noise in a vehicle that had just been sold to me as new. Because the selling dealer is so far away, and because I was concerned about driving a potentially unsafe vehicle long distance, I took it to a closer Chevrolet dealer for evaluation. I first brought the vehicle to Ciocca Chevrolet in West Chester, PA. After assessing the issue, they advised me to open a ticket with General Motors (GM) because they believed there was a legitimate defect that required GM involvement. Shortly after that, I left for the Christmas holidays, but the issue did not go away and I remained extremely concerned that I had just bought a defective vehicle. When I returned, I took the Blazer EV to Del Chevrolet in Paoli, PA for a second opinion and a thorough evaluation. After keeping the car and spending an entire day assessing it, Del Chevrolet acknowledged the problem. Despite two separate dealers identifying and acknowledging the issue, I have been unable to get timely action toward a repair. I have been told that GM is requiring additional testing and, most importantly, that GM is not authorizing Del Chevrolet to order the necessary parts. The dealership has indicated they are essentially stuck waiting for GM approval, which means my brand-new vehicle is in limbo with no clear repair timeline. As of now, the vehicle has only about 140 miles on it. This is a brand-new car that developed a serious noise immediately upon delivery, and I have now been forced into a loaner vehicle. It is Jan 17th. The vehicle is still at Del Chevrolet service center. Del Chevrolet, Fred Beans Chevrolet and GM corporate are involved in resolving this issue.

To Whom It May Concern, I am submitting this complaint regarding my **2024 Chevrolet Blazer** and the handling of my case by GM, GM Financial, and affiliated dealerships. In **sub-zero temperatures**, the heating system in my vehicle completely failed while I was transporting my **newborn child**, creating a serious safety concern. I immediately sought assistance at **Moran Chevrolet**, where I was denied service, told no loaner vehicles were available, and advised to continue driving the vehicle despite the dangerous conditions. Out of necessity, I drove over **30 miles** to **Al Serra Chevrolet**, where my vehicle was finally taken in. I was provided a **gas-powered loaner** and was explicitly told that fuel expenses would be covered through **GM Executive Concierge**. Unfortunately, my experience with GM Concierge has been unacceptable. I was assigned a representative but have **never spoken to her live**, despite numerous calls and clear communication of my availability. I have spent **hours** attempting to obtain reimbursement and assistance, without resolution. My vehicle is now **back in the shop**, and this matter remains unresolved. Additionally, although I have paid my vehicle payment to remain current, I am requesting **reimbursement of this payment**. This expense was incurred as a direct result of GM’s failure to provide timely service, a comparable loaner, and effective concierge assistance during a documented safety-related vehicle failure. I paid under necessity to mitigate further harm, and reimbursement is appropriate to fully resolve this matter. I am requesting: • Reimbursement for fuel expenses related to the loaner vehicle • Reimbursement of the vehicle payment made under necessity • A written explanation for the concierge communication failures • Assurance that safety-related failures are handled promptly • Confirmation that this complaint has been escalated

Telecommunications module failed - no Onstar, no Navigation which means no help to find charging station, and Mychevrolet app remote connection is not functional. Local dealer states this is a known issue but there is a significant backlog to investigate, and no loaner vehicles available. Wide spread issue across many GM vehicles. Very disappointing experience including service repair. Due to lack of loaner i am unable to drop off as this is my primary driven vehicle.
