While this vehicle was in motion the brakes suddenly stopped working. 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 vehicle is available for inspection upon request. The vehicle was towed to the dealership today and no answers have been provided. There were no symptoms or signs prior to the total brake failure.

The High Voltage System failed three separate times within the first 3 months of ownership. Has spent total almost 30 days in the shop getting repairs. It happened at 400 miles, 800 miles, and 2200 miles. The car was unable to charge, unable to drive at full Highway speeds, and was a safety hazard because it could shut down at any moment according to the manual. The last time it happened was while I was driving home from a work trip. I had to drive 100 miles in 100° heat without functional AC and at limited speeds, hoping that the car wouldn’…

Owner report 11579528 · 2024-03-26 (March 26, 2024)

Telescoping adjustable steering wheel would not lock into place. If adjusted to multiple different positions, the steering wheel would fall out of position and drop in height as well as in towards the dashboard without warning. This occurred several times while driving as well as while parked. Took back to the dealership and was told initially that it was just the locking mechanism that needed to be replaced. Now the dealership is telling me that the entire steering column needs to be replaced.

Forward Collision Avoidance: Automatic Emergency Braking	2228.2% ODI 11609909 The emergency collision avoidance braking automatically activated for no reason. Twice it happened at highway speed, once at 65 mph, once at 55 mph. On the 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. The other time at highway speeds - I didn't see anything in particular that it was reacting to. Once this happened at about 30 mph, I suspect it saw a dark patch of asphalt.

Unknown Or Other	1012.8% ODI 11607384 Dear NHTSA, I am writing to express concern about the excessive noise generated by the Pedestrian Warning System (PWS) on my 2024 Chevrolet Blazer EV. While I understand the importance of these systems for pedestrian safety, the current volume level is unreasonably loud and intrusive. The PWS on this vehicle activates at low speeds, (below 25mph), creating significant noise pollution both inside and outside the vehicle.

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.

I am averaging about 125 miles using about 70% of the fully charged battery. I WAS informed that during colder temperatures I would experience faster battery degradation but it was not mentioned that it could be as dramatic as losing 50% of my range.

Multiple safety-critical systems have malfunctioned since shortly after purchase, continuing to this day. The most serious is the forward collision braking, which has triggered randomly during normal driving. These braking events have occurred on highways and surface streets, posing a serious risk if a vehicle were following closely. During arbitration, the manufacturer admitted this is a known defect with no current fix, yet continues to return the vehicle marked as “repaired.” Additional issues include: Adaptive cruise control failure Interm…

Although the owner's manual specifically states "When enabled, One-Pedal Driving applies in R (Reverse) and D (Drive). This feature remains enabled until manually disabled by the driver." One pedal drive does not work in reverse. Car does not creep in reverse like an ICE vehicle, but quickly lurches backward, surprising an experienced or forgetful driver and possibly endangering pedestrians walking or standing behind the car.
