2027 Cadillac Optiq problems

Filed Nov 6, 2026 · Driver assistance · TX

The Acoustic Vehicle Alerting System (AVAS) on my Cadillac OPTIQ does not appear to be loud enough to adequately alert pedestrians of the vehicle's presence at low speeds. In my experience, pedestrians in front of the vehicle often do not notice it approaching until they see it visually. This appears to be a general concern with the Cadillac OPTIQ rather than an isolated issue. Because electric vehicles produce little to no engine noise, pedestrians rely on the AVAS warning sound for awareness. If the sound is not 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 the federal safety agency 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.

Upon opening any of the vehicle's doors, a repetitive "trak-trak-trak" clicking noise is heard for several seconds. The condition is noticeable only when a door is opened and occurs before the vehicle is started. The noise appears to come from a door-related actuator or motorized mechanism and sounds like gears repeatedly cycling or slipping while attempting to reach a position. Based on discussions with other owners and observations of multiple vehicles, this appears to be a widespread issue affecting brand-new 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.

I am submitting this complaint to report a potential safety concern regarding my Cadillac Optiq and its Acoustic Vehicle Alerting System (AVAS), which is designed to alert pedestrians to the presence of an approaching electric vehicle at low speeds. I live in a cul-de-sac where children frequently play in the street. Since purchasing the vehicle, I have noticed that the pedestrian warning sound generated by the AVAS is not noticeable enough to effectively alert pedestrians that the vehicle is 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 the federal safety agency 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

I had just pulled into a parking space and was positioning the vehicle to park. I was about to put the vehicle into Park when the vehicle suddenly jolted/accelerated forward unexpectedly. The vehicle went forward over/into the curb and struck the wall. The forward acceleration was unexpected and was not something I intended the vehicle to do. Because this is a new vehicle, I am very concerned that there is a vehicle, software, propulsion, braking, or electronic-control issue. I will be requesting that the vehicle 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.

This is the second report I am submitting for this vehicle: On October 17, at approximately 12:46 PM, I was driving my 2027 Cadillac Optiq from my home to Trader Joe’s (about two miles away from my home) when the car suddenly lost acceleration. My speed dropped from 30 mph to about 19 mph even though I was pressing the accelerator pedal. The car felt progressively heavier, as if the brakes were being applied. I stopped at a stop sign and turned on my hazard lights. When I started driving again, the car seemed to 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 the federal safety agency report about that incident.

On Wednesday, September 23, at around 7:00 AM, as I was driving on the northbound 163 Freeway in San Diego, my car suddenly lost power and began gradually limping to a staggering 10 mph speed among all the rest of the cars whizzing by me at 70 mph. The dashboard displayed a message that said “charging incomplete, try another charger” in spite of the fact that my battery was shown to be 80% full. At 10 mph, I could barely control the vehicle to get it more safely toward the shoulder of the road. I immediately activated the in-vehicle SOS system, but a tow truck did not arrive for about 80 minutes, during which I sat exposed on the shoulder of an active freeway.
