2024 Cadillac Lyriq

The 33-inch curved LED display running the latest Cadillac infotainment software experiences freezes, black screens, and reboots while driving. Apple CarPlay and Android Auto connections drop unexpectedly, the navigation map fails to render, and the climate control interface becomes unresponsive. Some owners report the entire display going black for several seconds before recovering, temporarily removing access to all vehicle functions displayed on the screen.

Dealer performs over-the-air (OTA) or wired software updates. GM has released multiple software patches since launch to address stability and connectivity issues. A hard reset of the infotainment system (holding the home button for 10 seconds) may resolve temporary freezes. If the display hardware is faulty, the screen module must be replaced.

The Lyriq may charge at significantly lower speeds than the advertised 190 kW peak DC fast charging rate, sometimes tapering to under 50 kW well before 80% state of charge. Some owners report DC fast charging sessions failing to initiate, stalling mid-session, or the vehicle's battery conditioning system not properly preconditioning the battery when navigating to a fast charger.

Ensure the battery is preconditioned by using the built-in navigation to route to the DC fast charger, which triggers thermal preconditioning. Dealer performs software updates to the battery management system (BMS) and charging control module. GM has released updates to improve charging speed consistency and session reliability. If the onboard charger module is faulty, it must be replaced.

The 12V auxiliary battery drains prematurely, especially if the Lyriq sits unused for several days. A depleted 12V battery prevents the vehicle from powering on, even though the main traction battery is fully charged. The numerous always-on electronic modules and cellular connectivity features draw current continuously, overwhelming the small 12V battery over time.

GM released software updates to reduce parasitic draw on the 12V system. If the 12V battery has been deeply discharged multiple times, it may need replacement. Using a 12V trickle charger or battery maintainer during extended periods of non-use is recommended. Ensure the vehicle's scheduled charging is set to avoid long periods in a fully charged but idle state.

The one-pedal driving mode and regenerative braking system exhibit inconsistent behavior, with the regen braking force varying based on battery state of charge and temperature. When the battery is fully charged or very cold, regenerative braking is significantly reduced, causing the vehicle to coast further than expected. Owners accustomed to the normal regen response are caught off guard by the reduced deceleration.

This is partly by design — regen braking is limited when the battery cannot accept energy (full charge or very cold conditions). GM has released software updates to improve the transition between regen and friction braking. The driver should be aware that regen force varies and be prepared to use the friction brake pedal. A software update may smooth the transition behavior.

Owners report excessive wind noise around the frameless front door windows and road noise intrusion through the floor and wheel wells at highway speeds. The frameless door window design allows air to whistle past imperfect seals, particularly at the leading edge of the front windows. The absence of engine noise in the EV makes these noise sources more noticeable than in comparable ICE luxury vehicles.

Dealer inspects and adjusts the door window alignment and weatherstripping. Replacement of the window run channel or door seal may be necessary if they are deformed. Aftermarket sound-deadening material can be applied to the doors, floor, and wheel wells. GM has released service procedures for adjusting the frameless door window seal on the Lyriq.
