Cadillac Optiq Problems by year

sufficiently audible, it may increase the risk of pedestrian accidents, particularly for children, elderly individuals, and visually impaired persons. I also believe the sound level may not comply with the minimum decibel requirements and effectiveness standards established by NHTSA for pedestrian warning systems on electric vehicles. The forward-facing warning sound does not appear to provide adequate notice of the vehicle's approach under normal operating conditions. This condition may create a safety risk for pedestrians and increase potential liability for vehicle owners who reasonably expect the AVAS system to provide sufficient warning. I am requesting that the volume level and effectiveness of the Cadillac OPTIQ's AVAS system be evaluated to determine whether it complies with applicable federal safety standards and provides adequate pedestrian awareness.

Cadillac OPTIQ vehicles and not an isolated defect. The noise is consistently reproducible by opening the door. I have compared the Cadillac OPTIQ to other Cadillac EV models, including the Cadillac LYRIQ and Cadillac VISTIQ, which utilize similar electronic door handle systems. Those vehicles do not produce the same clicking noise when the doors are opened, suggesting that this behavior is not normal across Cadillac's similar vehicle platforms. I am concerned that the repeated operation of the actuator and associated gears each time a door is opened could lead to premature wear of the internal gear mechanism. If the gears become damaged or stripped over time, the door-opening system could eventually fail. In a potential emergency situation, occupants or first responders may need to open the door quickly from the outside. If the actuator or gear mechanism has deteriorated due to excessive cycling, the door may not function as intended, creating a potential safety risk. At this time, the component has not completely failed; however, the repeated clicking noise appears abnormal and may indicate a defect that could lead to future failure of the door-opening system. I am submitting this complaint so that the issue can be investigated before it results in a more serious safety concern.

approaching. Even at low speeds and in residential settings, the sound is extremely difficult to hear unless a person is very close to the vehicle and actively listening for it. I brought the vehicle to an authorized Cadillac dealership to determine whether the volume of the AVAS could be increased. The dealership informed me that the system cannot be adjusted at the dealer level and that any changes would need to come directly from General Motors through a software or over-the-air update. I believe this condition presents a safety concern. The purpose of the AVAS is to provide an audible warning for pedestrians because electric vehicles operate very quietly. If the warning sound is not noticeable under normal conditions, pedestrians, especially children, may not realize a vehicle is approaching until it is too late. For this reason, I respectfully request that NHTSA investigate whether the AVAS on the Cadillac Optiq provides an adequate and effective audible warning in real-world driving environments and whether it fully meets the intent of pedestrian safety requirements. I also encourage a review of whether a software update or other corrective action may be necessary to improve the effectiveness of the pedestrian warning system. I am concerned that if this issue is not addressed, it could increase the risk of pedestrian accidents and create unnecessary safety and liability concerns for vehicle owners and the public. Thank you for your time and consideration

and all available electronic data related to the incident be preserved and that Cadillac/GM conduct a technical investigation before any repair, software update, reprogramming, reset, or deletion of diagnostic information is performed. Even after the recommended repairs, I am very concerned about driving this car with my children in it if they can't tell me why it jumped forward.

operate normally, and I drove it home and parked it. This is the second time the vehicle has lost power while driving. The first incident was on September 23, 2026, on northbound SR-163 in San Diego, when the car slowed to about 10 mph and displayed the message "Charging incomplete. Try another charger" with the battery at 80%. The car had to be towed to North County Cadillac in Escondido, and the dealership later reported finding no problem. I also filed an NHTSA report about that incident.
