2026 Cadillac Vistiq

Vehicle displayed a 'Lithium Ion Battery – Schedule Service Now' warning within approximately one month of delivery. Dealership service records later obtained by our attorney show the identical diagnostic condition was already present and was cleared via a system reset on the date of delivery, October 23, 2025, without disclosure to us. The defect was 'repaired' in December 2025 (diagnostic code P13FB, coolant control valve replacement) but recurred in May 2026, with the warning consistently reappearing whenever ambient temperature rose above approximately 80°F, accompanied by complete loss of air conditioning. The vehicle has been out of service since June 4, 2026. We consider this a potential safety issue given the recurring high-voltage battery fault and are concerned other VISTIQ owners may be experiencing the same condition without knowing it was present before delivery. Since retaining legal counsel, a temporary repair was made, but the vehicle is now also subject to a manufacturer recall that renders the third row unusable, with no permanent remedy currently available. We are concerned this reflects an unresolved and possibly unfixable condition affecting vehicle safety and usability.

My 2026 Cadillac Vistiq is covered by NHTSA Recall 26V394 (GM N262555780), concerning a third-row power-folding seatback that may fail to auto-reverse when it strikes an obstruction, risking entrapment of smaller occupants, particularly children. Component: the third-row power-fold seatback module and its power harness. Available for inspection on request. On [DATE], an authorized Cadillac dealer performed the interim recall remedy by disconnecting the power harness under the cargo floor trim. The Vistiq third row is power-actuated only, with no manual fold mechanism, so disconnecting the harness locks the seats in whatever position they occupy at that moment. I was not asked which position I wanted. The seats were left [FOLDED FLAT / describe] and cannot be raised. The third row is now completely unusable as seating. The dealer performed and confirmed this work; a repair order exists. I later asked the dealer to reconnect the harness, cycle the seats upright, then re-disable the power-fold so the seats would remain usable as seating pending the permanent module. The dealer refused. I also requested courtesy transportation adequate to my family's seating needs. The dealer refused. No availability date for the replacement module has been provided. Safety impact: this is a three-row SUV that now seats five. Occupants who would otherwise use the third row must sit elsewhere or travel separately. No warning lamps or messages preceded this; the loss of function is the result of the recall remedy itself, not a component failure. I am reporting this because the interim remedy eliminated a functional seating position, the dealer refuses to restore it in any usable configuration, and no timeline exists for the permanent repair. If the remedy is being administered this way generally, other owners in the recall population are losing third-row occupant capacity with no recourse.

I leased a new 2026 Cadillac VISTIQ on XXX. The vehicle had approximately 960 miles when the incident occurred. After DC fast charging at a Tesla Supercharger in Las Vegas, NV, the charging session did not complete normally. Shortly afterward, the vehicle displayed a “Reduced Acceleration – Drive with Care” warning message and vehicle performance was significantly reduced. The air conditioning also stopped cooling properly while outside temperatures exceeded 100°F. Because vehicle acceleration was limited and the warning indicated reduced propulsion performance, I did not feel comfortable continuing to operate the vehicle. I canceled a planned trip from [XXX] to [XXX] because I no longer believed the vehicle was reliable for highway travel. The vehicle was taken to the selling Cadillac dealership for diagnosis and remains available for inspection. At the time of this complaint, I have not yet received the dealership’s diagnosis or repair findings. This incident occurred on a brand-new vehicle with fewer than 1,000 miles. I am submitting this report because a sudden reduction in propulsion immediately following DC fast charging could create a safety concern if it occurs while merging, passing, or traveling at highway speeds.

I am filing a complaint regarding a GM Ultium Home EV Charging Station that failed while still under warranty. GM acknowledged the failure and sent a replacement, but the replacement was not equivalent to the original product. My original charger was a plug in model, but GM sent a hard wired model, which requires professional installation costing approximately $450. GM stated they no longer manufacture the plug in version and refused to provide an equivalent replacement or cover the installation cost. I contacted the GM EV Concierge (Case # 95387763)multiple times and escalated the issue. GM responded but continues to refuse to honor the warranty by either (1) providing a like for like replacement, or (2) covering the installation cost required solely because GM discontinued the original model. GM also suggested I “sell the charger” if I did not want to pay for installation, which is not a valid warranty remedy. The GM EV Concierge advised they stopped manufacturing the model of the EV charger I was sold because there were multiple failures. This situation leaves me without a functioning EV charger and forces me to pay out of pocket for a problem caused by GM’s product discontinuation. The failure of the charger and GM’s refusal to provide an equivalent replacement raises concerns about safety, reliability, and GM’s compliance with warranty obligations for EV charging equipment. I am requesting NHTSA’s review because this appears to be a pattern of GM not honoring warranty requirements for EV charging equipment, and consumers are left without safe and functional charging options. I would like a refund of the price I paid for the charger since they will not honor their warranty.

need this case escalated immediately as a serious safety incident. [XXX] around While driving my 2026 Cadillac Vistiq on [XXX] around [XXX]pm doing approximately 45 MPH.  The vehicle suddenly and violently activated automatic emergency braking with no vehicle, pedestrian, animal, or obstacle anywhere near me. The dash displayed a warning similar to:“Front Collision detected Brake now” The braking was severe enough to throw me violently forward and backward in my seat, causing neck and back pain that has continued after the incident. This was not normal operation. The vehicle created a dangerous situation and could have caused a rear-end collision if another vehicle had been following closely. I am requesting: Full diagnostic retrieval of all Forward Collision / AEB event data Inspection and calibration of all front collision sensors, cameras, radar systems, and Super Cruise related modules Documentation of any known technical service bulletins, software issues, or engineering investigations related to phantom braking or unwanted brake assist activation Written confirmation of findings Immediate escalation to GM Technical Assistance and Cadillac Engineering I also request preservation of all vehicle event data associated with this incident. This event caused physical injury symptoms including neck and back pain consistent with whiplash-type force from abrupt emergency deceleration.

The dashboard/infotainment screen keeps alerting and going blank. I will be driving and will no longer know how fast I am going, nor if my blinkers work, or have any control of the screen. This will stay like this for seconds to hours. I have taken the vehicle in several times (Invoices from 8/26/26, 9/11/25, 10/21/25) and eventually had the F module replaced. This resulted in the system working for a time. Then on February 20th, 2026 the issue began again while driving. I tried a system reset on the dashboard, which seemed to resolve the issue for a time. The issue again began on 3/14/26 while driving. I again performed a system reset but the problem remains. I am unable to tell how fast I am going or if any of the electronics work. The onstar light is red and I do not get any response from the system controls. I have lots of videos of these issues saved to my phone and reported to Uftring Montgomery in Peoria Illinois
