My 2024 Cadillac LYRIQ generated the following High Voltage Battery fault codes via On-Demand Diagnostic: U2B4A, U2B4D, U2B50, U2B53, U2B56, U2B59, U2B5C, U2B5F, U2B62, U2B65, U2B68 — all under module VIC - Lithium-Ion Battery. Multiple codes are flagged "Service Right Away" indicating an active fault in the high voltage propulsion battery system. I brought the vehicle to Lindsay Cadillac, Alexandria VA [XXX] ) on [INSERT DROP-OFF DATE]. As of today [INSERT TODAY'S DATE], the vehicle has been sitting at the dealership for [X] days with ZERO repair action taken. The service manager has stated he does not know what to do, has no timeline, and cannot provide any answers. GM Technical Service Bulletins PIP6009B and 25-NA-044 specifically cover these exact DTCs and provide a documented repair procedure. The dealer has failed to follow or initiate this procedure. No loaner vehicle was provided despite this being a warranty repair on inoperative vehicle. I have been forced to rent a vehicle at $125/day out of pocket. I have an open Cadillac Concierge case number [93707662 #]. Cadillac Concierge was unable to reach the dealer's service department by phone. I have escalated in writing to GM's executive office including [XXX] and [XXX] with no resolution. This is a high voltage battery fault on an all-electric vehicle flagged as "Service Right Away" severity. The vehicle remains unrepaired, the dealer is unresponsive, and GM's own customer service cannot reach the dealer. This represents both a safety concern and a complete failure of the warranty service obligation. I am requesting NHTSA investigation of both the underlying battery defect and the dealer's failure to act on a known TSB.

Component: Electronic Stability Control / Navigation / GPS Complaint: Since the February 2026 over-the-air software update, the built-in Google Maps GPS has been severely malfunctioning. The system consistently fails to update my vehicle’s location, showing me as stationary at my home address even after driving for 30+ minutes and 20+ miles away. This is not an intermittent glitch — it renders the native navigation system completely unusable after nearly every drive. Prior to the February 2026 update, the GPS functioned perfectly. The issue began immediately following that update and has persisted despite infotainment system resets and checking for further software updates. I am aware that GM has internally acknowledged this issue via Preliminary Information bulletin PIC6644 (issued February 2026), which attributes the problem to a “software anomaly” and confirms engineering is investigating. However, no fix or timeline has been provided to customers. A GPS system that does not reflect the vehicle’s actual location is a safety concern — particularly when relying on navigation for routing, hazard awareness, or emergency response. I am filing this complaint to ensure this issue is part of the public record and to urge NHTSA to monitor the scope of this defect across 2024 Lyriq vehicles

At least 10 times over the past three months the vehicle’s feature of one pedal driving disengages without a reason or code. When the this happens the vehicle accelerates rapidly. This has happened on local streets and on the highway and often results in a near miss collision. I am concerned this will result in a serious injury or death.

I pulled my vehicle in my garage and was lightly tapping the accelerator to get the vehicle far enough in to avoid it interfering with the garage door. I had one-pedal driving engaged so I was not using my brake pedal. Once positioned I was getting ready to put it in park and the vehicle rapidly accelerated as if someone was stomping on the accelerator. It slammed into a refrigerator I have in the garage, pushing it about 2 inches into the wall, breaking through the drywall. The impact was so hard the refrigerator door also popped open and stuff went flying out. I had to slam on my brakes to get it to stop moving forward even though my foot was not on the accelerator.

The vehicle initially had a windshield manufacturing defect according to Cadillac Service Center which allowed plenty of water to go inside the vehicle during heavy rain. After the vehicle was serviced weeks later I was driving and the digital dashboard when completely yellow and red. At the same time the automatic brakes activated and I almost got rear ended. They serviced the car again after being tow trucked and “couldn’t” determine the cause of the dashboard incident shown on the pictures.
