2024 CADILLAC LYRIQ Complaints
The vehicle is a Cadillac Lyriq. Following an over the air software update pushed by the manufacturer, the vehicle began displaying a high voltage system error message and lost the ability to DC fast charge. The high voltage components themselves are reported to be functional, the issue appears to be caused entirely by the software update rather than a hardware failure. The vehicle has been at an authorized dealership service center since August 14, 2026, awaiting a resolution. The dealership has confirmed the fault is present and is consistent with a known issue caused by the manufacturer's software update, but has not been able to repair it independently, since the fix requires a corrected software release from the manufacturer. As of this writing, the manufacturer has not issued the corrected update and has not provided a timeline for when one will be available. This creates a safety risk because the vehicle cannot be relied upon for longer trips or situations requiring DC fast charging, which can leave the driver stranded or unable to reach a destination or charging option within a safe range, particularly in hot weather conditions common in this region. The warning message and loss of fast charging capability appeared immediately after the software update was applied, with no prior symptoms. It is unknown whether the manufacturer has independently inspected this specific vehicle beyond the dealership's diagnosis. The high voltage system and charging hardware remain available for inspection upon request. Multiple other owners of this same model have reported the identical issue following the same software update, suggesting this is a widespread defect rather than an isolated incident.;
2024 CHEVROLET BLAZER EV Complaints
I am reporting a potential safety defect involving unintended automatic emergency braking/forward collision warning/brake-control behavior, reverse automatic braking, parking brake behavior, and driver-assistance/sensor calibration. Incident XXX ~11:15 AM, [XXX] driving 2024 Chevrolet Blazer EV ~20–25 mph on/near [XXX]. Vehicle displayed red collision alert and abruptly braked hard although the lane was clear; only a car was parked in a driveway on the right. Sudden braking created serious risk of rear-end collision/loss of control. Vehicle used for family transportation; toddler (~30.8 lb) had been in vehicle ~10 minutes before and family includes blind/visually impaired passenger. History of unwanted reverse emergency braking ~every 45 days: Jan 2026 near Crust Pizza Woodforest (backing up) and March 2026 at H-E-B 7988 FM 1488 Magnolia (backing out), jolting child in rear-facing car seat. Prior service at Keating Chevrolet Nov 12, 2025 (including recall/service for Unintended Parking Brake Engagement N252503010 and missing chassis harness plugs update) did not resolve unwanted braking. After June 10, AEB/front pedestrian braking/intersection collision braking were disabled as temporary safety mitigation. Vehicle removed from daily family use, available for inspection, and I request NHTSA review. Any inspection should preserve relevant braking/parking/AEB/forward collision/sensor data before any reset/update/repair.

2024 CHEVROLET SILVERADO EV Complaints
I own a 2024 Chevrolet Silverado EV WT equipped with the OEM soft tonneau cover. The original cover and its warranty replacement have both failed in the same way. The cover material appears to shrink over time so that the side flaps will no longer reach and stay attached to the Velcro along the bed rails. At highway speeds the cover flaps and “balloons” upward, and the Velcro strips will not stay connected even when properly installed and tightened. The dealer has already replaced the cover once under warranty, but the replacement has the same problems. This suggests a design or materials defect, not a one-time bad part or installation error. In my opinion, the flapping and ballooning could allow the cover to come loose or detach at speed, which could create a road hazard for other drivers. I am asking NHTSA to track these failures and evaluate whether the OEM soft tonneau cover on the Silverado EV presents a safety risk similar to prior GM tonneau cover issues where covers detached while driving.;
2024 GMC SIERRA EV Complaints
The contact owns a 2024 GMC Sierra EV. The contact stated that while operating the vehicle the front trunk had erroneously opened. During the failure the vehicle would not shift out of the park position and the warning message indicating that the door was unsecured had displayed. The contact indicated that the failure had occurred on multiple occasions and the battery was disconnected to reset the system and correct the failure. The cause of the failure was not determined. The manufacturer was notified of the failure. The local dealer was not yet contacted. The failure mileage was 15,000.;
