Lemberg Law is investigating consumer complaints about the 2024 Chevy Blazer. A mid-size SUV, the 2024 Blazer is available in several trim models that include Chevrolet’s first-ever electric super sport performance model. The automaker emphasizes the SUV’s safety features, including Enhanced Automatic Emergency Braking. It boasts that the Blazer EV offers “cutting-edge technology, dynamic design, and unprecedented powertrain choices.” But our investigation shows that consumer complaints tell a different story.
Introduction
There are more complaints to the National Highway Traffic Safety Administration (NHTSA) about the 2024 Blazer EV than other models. However, all models, including the Blazer EV, have elicited complaints about the electrical system, forward collision avoidance, powertrain, service brakes, and steering. Consumers state that the 2024 SUV also has issues with the airbags. 2024 Blazer EV owners also highlight additional problems that relate to the engine, fuel/propulsion system, structure, vehicle speed control, and complaints filed under Unknown or Other.
We have chosen to focus our investigations on problems relating to the electrical system, brakes, and transmission.
Additionally, three recalls affect the 2024 Blazer EV, only one of which also relates to the more conventional SUV. None relate directly to consumer complaints.
The shared recall is an issue with the structure of the vehicle. NHTSA Campaign Number: 23V869000 warns that certain 2024 Chevrolet Blazer, Blazer EV, and other GMC vehicles have door strikers that may fracture.
There is only one complaint about the structure of the EV, and it isn’t about this. Rather, an owner from Michigan states that the liftgate intermittently closed independently after opening with the fob key. The failure mileage was only 25 miles, and the owner expressed concern that someone might be injured if this happened again.
NHTSA Campaign Number: 24V487000 warns that some 2024 Chevy Blazer EV vehicles may have a right front lower control arm with a manufacturing defect that can cause it to fracture. This could cause drivers to lose control of their vehicles, increasing the risk of a crash. There are no complaints that relate to suspension.
During our investigations, we also discovered that NHTSA Campaign Number: 24V320000 reports an electrical system problem that affects the Chevrolet Blazer EV as well as several other Chevrolet, Cadillac, and GMC vehicles. This recall alerts affected vehicle owners to insufficient wire insulation in the electric motor. The danger is that the wires could touch each other resulting in a loss of drive power. This increases the risk of a crash.

Owner Experience Overview
Electrical system complaints top the list of complaints overall, but there is no single reason for these complaints. The two biggest problems seem to be issues with display screens and the battery. Brakes are also an issue, with complaints reporting brake assist and brake failure. There are several powertrain complaints, but again, the issues are varied.
We have included transmission problems in our investigation because numerous service bulletins warn dealerships of potential problems.
Electrical System
An owner from Mississippi states that the backup camera in an EV failed and the instrument cluster didn’t appear. “I did a reset on the infotainment and the entire instrument cluster and infotainment set of screens stayed black. I had to leave the area so I ended up driving a few miles with no gauge cluster, camera system, or dash indicator lights. Eventually, this was rectified by leaving the vehicle off for several minutes, but now I fear this issue will return unexpectedly again.”
An owner from Arizona also had display issues. “The display would go blank while driving. I was unable to turn the vehicle off due to the controls not being accessible on the display. There was a grinding noise inside my dash and the ‘service vehicle soon’ light (came) on. The climate controls are unavailable resulting in high heat on defrost.”
High Voltage Battery Problems
“The high voltage system and charging system have both failed in this car three separate times,” says an owner from Utah. This happened soon after purchase, and in 110 days of ownership, it was in service for 50 days. “The manager at the dealership told me that a lot of the Blazer EVs that they have sold have had this exact issue and that GM doesn’t seem interested in actually fixing it. They change sensors in the car but don’t want to spend the money actually fixing the battery.”
An owner from New Hampshire states, quite simply, that the lithium-ion battery wasn’t performing as expected. The problem was in the onboard charging system.
Brakes
An owner from Michigan states that electronic stability control (ESC) and brake assist failure codes were displayed in a Blazer EV. Then on starting the car, it wouldn’t brake. Restarting the Blazer resolved the issue temporarily, but the problem recurred.
Another EV owner states that the brakes suddenly stopped working while driving. “The brake pedal went to the floor with no braking. The screen read brake assist failure. Safety was at risk due to being unable to stop the vehicle until it slowed itself down. This could have resulted in a fatality.” The complaint continues, stating that there were signs before the total brake failure. “Other messages on (the) screen read: one pedal driving disabled, parking brake disabled, rear parking assist disabled.”
The owner of a regular SUV describes how when turning, the car “flashed the light in the front window, the alarm went off and slammed the brakes as if something was in front of me. Nothing was in front of my car in the left lane. Luckily there wasn’t a car on my rear bumper otherwise I would have been rear-ended.” This was the second time it had happened.
Similarly, an EV owner states that emergency collision avoidance braking is automatically activated for no reason. It happened twice at highway speed, once at 65 mph, and once at 55 mph. “On one occasion we were approaching a highway overpass, it was bright and sunny. “I suspect the system saw a shadow that it thought was somehow going to be a crash and momentarily activated brakes.” There was no obvious explanation for the other incidents. Afraid of getting rear-ended if it happened again, the owner disabled the system.
Transmission & Powertrain
There are several powertrain complaints, but most are combined with other components, like the Arizona owner who heard grinding noises inside the dash. This person also experienced periodic vibrations when driving on smooth roads. “They are not able to address the issues stating that parts are on backorder. My complaints to GM have not resulted in my request to return the vehicle for a full refund. The GM concierge has called me four times and keeps telling me they will need to call me back after asking questions I have already replied to. GM put a stop sale on this vehicle after selling about 500, and they have not addressed my concerns.”
Service Bulletins
There are all sorts of service bulletins for dealerships that relate to the transmission. These include:
A bulletin that provides information on a “driveline clunk noise,” stating what is acceptable and what is considered normal operation.
One that discusses how the transmission case leaks fluid due to porosity around a mount bolt hole. Dealers are told to replace the transmission case if this problem is identified.
Another provides technicians with information to help identify the differences between what is considered a fluid leak, and what is considered fluid seepage.
Another bulletin that provides information on the harmful effects of water or ethylene glycol in transmission fluid.
One of the most disturbing bulletins was published in June 2024. It states that certain 2024 Blazers and several other Chevy models might have an issue regarding their internal transmission components. It relates to the clutch backing plate retaining ring and/or the clutch piston retaining ring inside the transmission. If affected, vehicles will need to have the clutch piston housing replaced at a dealership before July 31, 2025.
