2026 Chevrolet Equinox EV Problems

On Saturday, August 29, 2026, at approximately 12:00 PM, I was driving my 2026 Chevrolet Equinox EV RS on the highway at about 65 mph. The weather conditions were clear and sunny. Without warning, the vehicle's automatic emergency braking (AEB) system abruptly engaged with full force, causing a severe and sudden deceleration. There were no vehicles, pedestrians, or obstacles in front of my vehicle at the time. There was active traffic trailing my vehicle. Fortunately, the driver directly behind me had enough following distance to react in time and avoid a severe rear-end collision. Today, August 31, 2026, I spoke directly with my Chevrolet dealership, and they confirmed that my vehicle's software had already been updated to be compliant with GM TSB #N252521591 (Image Processing Module / Unwanted Integrated Brake Assist) prior to this event. This phantom braking event occurred despite the vehicle already having the official software patch applied, indicating that the safety hazard persists.

I feel compelled to report this issue after 3rd incident and also after raising with the dealer service. I think this is a very very serious issue which should be investigated and dealt with promptly before it results in serious death or debilitating injuries. Let me describe the latest incident that happened yesterday with me in [XXX] between on XXX between 10:30 - 10:45 am PT. I was in a parking lot looking for a parking spot possibly driving at about 10-20 mph. A vehicle approached from the opposite side and it suddenly it slammed emergency braking. I and my family were shaken and felt a crushing jerk. This has also happened at least twice before - one time when I was pulling out of my driveway and another time on highway 1 in [XXX] near [XXX]. The highway incident could be very dangerous but possibly the slow traffic saved us. Driver behind me who is a friend called me immediately asking why I braked unsafely which I told him I did not. I have also 2 prior issues before the latest to the dealer who listened to me and documented it but I was told they don’t know anyone reporting this issue. Internet forum talks about this issue but OEM is possibly ignoring it. The dealer says they updated some camera software but that’s about it. This 3rd incidence has shaken me and I thought of reporting to you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On numerous occasions, while driving either on highways or streets, vehicle would brake on its own or aggressive braking when this type of braking was unnecessary. I was hospitalized for whiplash in one incident. After braking for NO REASON!!! GM sent a tow truck to pick up my vehicle, and I have not heard back for more than 100 days. If GM cannot fix this issue as stated in [XXX] then I should be compensated for the lack of use and my medical bills as well as loss of use. Not having a recall does not mean DEFECTS are not occurring!!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On February 23, 2026, while driving my 2026 Chevrolet Equinox EV home from Folsom Chevrolet following a prior repair visit, the “Service Park Assist System” warning illuminated, first intermittently, then after a few miles, continuously for the remainder of the 11-mile drive home. During the same drive, while reversing with no objects present behind or around the vehicle, the automatic emergency braking system activated and applied the brakes with significant force without cause. The vehicle was returned to Folsom Chevrolet (Repair Order #559378, opened February 23, 2026). Diagnostic code U1126 was found — indicating the left rear short range radar sensor had lost communication on CAN Bus 8. The sensor module was on national backorder, keeping the vehicle out of service for approximately two weeks. The module was replaced and programmed on March 7, 2026. Safety concern: Unexpected activation of automatic emergency braking with no objects present creates a serious collision risk from following traffic. This failure occurred on public roads during normal driving. Additionally, the U1126 CAN bus communication fault is the same vehicle communication architecture implicated in the battery/electrical failure documented in Repair Orders #558923 and #559167, suggesting these failures share a common root cause in the vehicle’s electrical communication network rather than representing isolated component failures.
