What owners report
Owners of this model year most often report braking problems, including unexpected automatic braking from forward-collision systems and parking brake recall repairs waiting on parts. Transmission problems such as jerking, hesitation and failure to shift are also common, along with sudden power loss while driving. Where mileage is listed, reports range from about 1,650 to 48,100 miles.
- Forward collision avoidance
Unexpected automatic braking from forward-collision system
- 11 complaints (21%)
- median 24,300 mi at 2.1 yrs old (2 state mileage, few)
- 1 mention a crash, fire or injury
- filed 2024–2026
Owners describe the forward-collision or automatic emergency braking engaging with no obstacle in front, often during left turns or while pulling forward from a stop. A complaint describes the brakes not releasing for a period, and another says a warning light and alarm came on along with the braking. According to complaints, the dealer could not determine the source of the failure in some cases, and the vehicle was not repaired. Mileage is rarely listed; where it is given the figure is about 40,000 miles, and most descriptions involve left turns or pulling forward from a stop.
What to check: Ask whether the front camera module has been inspected under a current bulletin, and ask the dealer to record any forward-collision or automatic braking events in the service history. Note when the braking happens, such as during left turns or when pulling away, and share those details with the dealer.
2 excerpts from owner complaints in NHTSA records
“The auto emergency braking engaged while making a left turn. No cars in front. Had someone been behind me, they could have easily hit me. The seat belt locked as well resulting in being able to feel the seat belt inprint hours afterwards. This incident just happened on 11/24/25 and has not be inspected by any dealership or service center. There were no warning lights or messages prior to the incident.”
NHTSA complaint #11701484, filed 2025-11“This morning, I stopped to open the gates at work, car was idling. When I got back into the car, put it in drive and started to slowly move forward the FORWARD COLLISION SYSTEM slammed on my brakes and lights flashing on my dash. I backed up...there was absolutely nothing in my way. This has happened numerous times, different places and while turning a corner at a very slow speed. Never nothing in the way. Will definitely be taking it in to have it checked now.”
NHTSA complaint #11769251, filed 2026-10 - Brakes
Parking brake recall repairs waiting on parts
- 11 complaints (21%)
- median 22,000 mi at 2.0 yrs old (3 state mileage, few)
- 2 mention a crash, fire or injury
- filed 2024–2026
Owners describe a parking brake recall where the repair was delayed because the dealer had to order parts or the parts were not yet available. Some describe the vehicle not moving in reverse or braking unexpectedly, including a crash, and some say the problem returned after the recall repair. A complaint says the recall was not properly inspected, and that holes in a brake harness were described to the owner as a drain feature. Where mileage is listed it ranges from about 8,600 to 34,900 miles, and several reports describe the repair waiting on parts for months.
What to check: Ask the dealer for the current status of the parking brake recall on this vehicle, and check the NHTSA recall lookup using the VIN before buying. Keep written records of recall visits, parts orders and any notices that the recall remains incomplete.
2 excerpts from owner complaints in NHTSA records
“Chevy of Wasilla, AK did not properly inspect a safety recall for the rear parking brake harness. After I showed the dealership the pictures of the holes in the brake harness, I was told that the holes in the brake harness is a feature to let water out. Pictures are attached of said holes in brake harness and text message with dealership representative.”
NHTSA complaint #11710800, filed 2026-01“Since buying the car in 2024 I have experienced multiple incidents where the system hard brakes for no reason, including times while driving. The emergency recall on this vehicle was repaired last year and since that repair this issue has occurred 2 more times, once earlier in 2026 and then most recently as yesterday despite claims by GM the issue has been fixed. My daughter currently drives this vehicle and is afraid she is going to get into an accident because of this issue. …”
NHTSA complaint #11764194, filed 2026-09 - Transmission and drivetrain
Transmission jerking, hesitation or failure to shift
- 7 complaints (13%)
- typically at 2.0 yrs old
- filed 2024–2026
Owners describe jerking or hunting for gears, rough shifts, whining or grinding noises, and at times a transmission failure that leaves the vehicle unable to move or shift. Several complaints say repairs took a long time because parts were on backorder, and some describe a valve body or full transmission replacement. According to complaints, in some cases the dealer was unable to fix the problem after several visits. Several reports describe problems early in ownership, including a failure at about 1,150 miles and another at about 1,650 miles, and most do not list mileage.
What to check: Ask the dealer whether the transmission has already had a valve body or full replacement, and whether any parts are still on backorder. Test the transmission during a test drive at low speed, including reverse, stops and gentle acceleration, since complaints describe jerking and rough shifts.
2 excerpts from owner complaints in NHTSA records
“The transmission in my 2024 Chevrolet Blazer is very noisy often making whining and grinding sounds and I experience rough shifting and transmission hesitation during acceleration or gear changes.”
NHTSA complaint #11688917, filed 2025-09“the car jumped/jerked like it was trying to change gears while accelerating and two times when at a complete stop at a light. The car was taken to dealership on Sep 2, 2025 and needed a full transmission replacement. The parts were on back order and the vehicle was not complete until November 20th of 2025”
NHTSA complaint #11770515, filed 2026-10 - Engine
Sudden power loss or engine failure while driving
- 11 complaints (21%)
- typically at 2.5 yrs old
- 1 mention a crash, fire or injury
- filed 2024–2026
Owners describe a sudden loss of engine or propulsion power while merging or driving, with the vehicle stopping in some cases. Others describe a knocking engine with the warning light on, and a sudden drive train failure that immobilized a vehicle. A complaint says the dealership found damaged catalytic converters after a power loss on a freeway on-ramp. Mileage is mostly not listed, although a knocking-engine report gives about 11,200 miles, and the power losses described occurred while driving.
What to check: Ask the dealer to scan for stored fault codes, including any engine light history, and check whether a catalytic converter or engine repair has already been done. Listen for any knocking during a test drive, since complaints describe engine noise and power loss while driving.
2 excerpts from owner complaints in NHTSA records
“I was driving to work as I normally do and work is only 15 miles away from home I get to work turn into the parking lot stop to scan my badge and I hear knocking noise I thought it was coming from the truck in front of me but after he moved on I still heard the noise and I found a parking spot as soon as I could and the engine light on the dash came on and the motor that was knocking is definitely my Blazer with only 11,222 miles on it. …”
NHTSA complaint #11725131, filed 2026-03“Transmission & engine failure. Press the gas and it doesn’t move the car-feels as if it is trying to change gears and it isn’t working. Car under warranty & still not working. Been to the dealership multiple times and they are unable to fix the issue. No warning signs.”
NHTSA complaint #11696006, filed 2025-10 - Brakes
Brake assist failure or reduced braking response
- 13 complaints (25%)
- median 34,865 mi at 2.6 yrs old (5 state mileage, few)
- 4 mention a crash, fire or injury
- filed 2024–2026
Owners describe a sudden loss of power brake assist, or braking that did not slow the vehicle as expected, sometimes with dashboard messages about brake assist failure or a reduced top speed. A complaint describes the vehicle accelerating during braking, with the problem lasting several miles, and another describes a crash after the brakes did not respond. Some say the dealer kept the vehicle for repairs without providing a loaner or rental. Where mileage is listed it ranges from about 5,500 to 48,100 miles, and a complaint describes a new vehicle with the problem continuing over a period of months.
What to check: Ask the dealer for the service history of any brake assist or ABS warnings on this vehicle before buying. Ask whether a loaner or rental is provided when a braking repair takes several days, since complaints describe vehicles kept for repairs without one.
2 excerpts from owner complaints in NHTSA records
“Breaking system not properly working . The car is brand new and the issue is going on for 2 months. Chevy dealer want to have the car for 7days but they don’t want to provide loaner or a rental. This is a dangerous issue and dealer seems to don’t care!”
NHTSA complaint #11620114, filed 2024-10“While driving my 2024 Chevrolet Blazer EV, the vehicle suffered a sudden, complete failure of the power braking assist system. The failure was accompanied by a rapid cascade of three sequential dashboard warning messages in immediate succession: First Warning: Service ESC illuminated alongside the Brake Park warning light. Second Warning: Brake Assist Failure. Press Hard to Brake. Speed Limited illuminated with Brake Park remaining on. Third Warning: Brake System Failure. 62 MPH Top Speed illuminated with Brake Park remaining on. …”
NHTSA complaint #11748905, filed 2026-07
Buying note. Before buying, ask the dealer whether the parking brake recall referenced in complaints has been completed, since several complaints describe long waits for parts. A test drive that includes low-speed turns, stops, pulling away from a stop and gentle acceleration may help show whether the braking or transmission behavior described above occurs on that vehicle.

Example complaints
Brakes: “Auto hold was on, radar cruise control was set and as I was merging in traffic a sharp smell of burning started. The cruise control refused to disengage until I parked the car in garage. Eventually burn smell ended but seems like brake was stuck while acceleration causing a burn smell. It seems like brake could get stuck to wheels perhaps when auto hold is on even when driving? Auto break hold is a feature which keeps the break on while car is stopped.”
NHTSA complaint #11773103, filed 2026-10Forward collision avoidance: “I was driving down the highway at 70mph using the adaptive cruise control. There was nobody in front of me, and suddenly the vehicle started picking up speed. I looked at the cruise control and it said 115mph, so I hit the brakes to override it and slow down. when I reset it for , ~70mph again it worked fine. This happened to me two other times with the same basic scenario. The speed is always over 100mph, and it always occurs when the adaptive cruise control has been in use for at least 30 minutes. I have an appt with the dealer that I bought it from to have it looked at. …”
NHTSA complaint #11630250, filed 2024-12Other or unknown: “There is a defect in the motorized electric charge port door. When you press the button it rarely works to open the charge port door leaving me with unable to charge my vehicle. I fear this will leave me stranded and my only course of action will be to rip the door off in anger. Many others are experiencing this issue. Chevy needs to address this.”
NHTSA complaint #11726216, filed 2026-03Transmission and drivetrain: “Vehicle has only 1650 miles on it. It is driven conservatively especially so during the first 1000 miles of use “break in period”. Was leaving our neighborhood and the vehicle was searching for a gear, revving and jerking. Check Engine light came on. Limped the vehicle slowly back home and contacted dealer. Had vehicle towed to dealer and they diagnosed the issue as a faulty valve body. Part is on national backorder.”
