2024 Cadillac Lyriq Problems

What owners report

Complaints on this model year cluster around two themes: the driver-assist braking system engaging when owners see no obstacle in front of or behind the car, and a set of electronic and software faults affecting the dash display, propulsion, and charging. Reports arrive at low mileage as often as not, and many owners tie the onset of trouble to an over-the-air software update; several describe repeat dealer visits without a lasting fix.

1. 1
   Forward collision avoidance

   Phantom automatic emergency braking

   • 22 complaints (19%)
   • median 3,400 mi at 1.1 yrs old (3 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2023–2026

   Owners describe the car braking hard on its own with nothing in its path, whether backing out of a driveway or parking space in rain, pulling into a garage, or cruising at highway speed. Some say the stop is forceful enough to feel like a collision and that traffic behind has to swerve. Complaints describe repeated attempts to back up being interrupted several times before the car will move, and dealers telling owners that nothing can be done or that the vehicle is operating as designed. Reported across the mileage range in the sample, often while reversing in rain or at low speeds around driveways, garages and parking lots.

   4 related service bulletins

   What to check: Ask whether the front camera module and any related software updates have been addressed, and whether the dealer has records of automatic braking events. On a test drive, try reversing out of a sloped or wet driveway to see whether the car brakes on its own.

   “While driving my 2024 Cadillac Lyriq in rolling traffic, the vehicle abruptly engaged the brakes without warning or cause. The braking was so forceful I initially thought I had been rear-ended. Once the braking event ended, I began to accelerate—only to discover the vehicle had shifted into reverse without any input from me. This resulted in a rear-end collision. There were no alerts or dashboard warnings to indicate the gear change. …”

   NHTSA complaint #11663564, filed 2025-05

   “I was driving the car on the turnpike and out of nowhere the rear collision system went offline and the automatic breaking was triggered while I was going 70 mph in rush hour. The brakes started to smoke and smell and the the warning of ‘breaks overheating. do not drive. call service’ happened. I proceeded to narrowly avoid many cars on the road by having to cross three lanes of traffic over to the shoulder and the car was fully smoking, I quickly turned it off I got out and stepped away. …”

2. 2
   Brakes

   Brake pedal response and ABS behaviour

   • 32 complaints (28%)
   • median 3,000 mi at 0.6 yrs old (7 state mileage, few)
   • 11 mention a crash, fire or injury
   • filed 2023–2026

   Complaints describe occasions where the brake pedal was pressed firmly and the car did not slow as expected, sometimes ending in a rear-end impact at low speed. Others report the anti-lock system engaging during ordinary braking in one-pedal mode, producing inconsistent pedal feel. Several owners say the dealer could not reproduce or find a fault, and some mention a brake system warning message appearing beforehand. Mostly reported at low speeds in stop-and-go traffic, with many complaints filed under 20,000 miles.

   Recall 24V589000

   What to check: Confirm with the dealer whether the ABS software recall (campaign 24V589) has been completed, and note that some owners report the symptom returning afterward. Ask for any stored brake or ABS codes.

   “As I approached a stop sign and hit the brake the car did not stop. I pounded on the brake but there was no response at all; it just coasted forward. The car continued to move and hit the car in front of me stopped at the stop sign. That car, a Nissan Rogue, had no damage. I was barely moving but the plastic sheet in the front of the Lyriq was cracked.”

   NHTSA complaint #11590072, filed 2024-05

   “There was “Brake System Failure” message on the EV’s digital display. It happened 3 times in less than a month. When it happened, I had to apply the break very hard. Otherwise, the car would not stop completely and would not hit the car in front. Top speed is limited 43 mph so I could not drive it on freeway.”

   Electrical system

   Loss of drive power or electrical shutdown

   • 34 complaints (30%)
   • median 5,000 mi at 0.8 yrs old (4 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2023–2026

   Complaints describe the car losing propulsion or all electrical power without warning, sometimes at highway speed and sometimes in a parking garage, leaving the vehicle unable to move, shift to neutral, or in one case be unlocked normally. Owners mention electric drive unit and high-voltage battery diagnostic codes and vehicles sitting at dealerships for extended periods awaiting parts or diagnosis. Reported from a few thousand miles up to around 30,000 miles, in varied driving conditions.

   Recall 24V320000Recall 25V3560003 related service bulletins

   What to check: Ask the dealer to confirm the rear drive unit recall (24V320) and instrument cluster recall (25V356) were completed, and to pull stored high-voltage and drive unit codes. Ask about any history of the vehicle being towed or held for service.

   “- Software failure resulted in loss of steering control, speed control, and brakes became unavailable. I was on highway car was at 65 mph and then I got a bunch of error messages mentioned below- 1) Steering assist not available 2) AWD is disabled 3) Headlamps not available 4)Service brake assist And then I was not able to brake the car, and steering became highly unresponsive. …”

   NHTSA complaint #11650230, filed 2025-03

   “After a manufacturer-initiated software/system update was performed on my 2024 Cadillac Lyriq approximately two weeks ago, the vehicle stopped charging and stopped generating heat. I brought the vehicle to Cadillac Norwood MA for diagnosis. The dealership informed me that a replacement part is needed, but the part does not currently exist and must be manufactured by General Motors. They could not provide any timeline for when the part would be available or when the vehicle would be repaired. …”

   Electrical system

   Infotainment and instrument display failures

   • 19 complaints (17%)
   • median 99 mi at 0.0 yrs old (1 states mileage, few)
   • filed 2023–2026

   Owners report the centre screen freezing, going blank, or showing garbled content, and in some cases the instrument cluster failing to show speed, gear or turn signals, or showing the wrong speed. Complaints describe the dash stuck on a welcome screen and requiring a drive to the dealer without gauges. Repairs mentioned include replacing the radio and display modules and repeated reprogramming, with the problem returning in some vehicles. Reported throughout the sample, from early ownership onward and at moderate mileage.

   Recall 25V3560004 related service bulletins

   What to check: Check whether the display recall (25V356) and any radio or display reprogramming bulletins were applied, and ask whether the cluster has ever failed. Watch the screen through a full start-up cycle on a test drive.

   2 excerpts from owner complaints in NHTSA records

   “Vehicle dash won't activate beyond the welcome screen thereby preventing me from seeing the speedometer, fuel gage, lane sensors, navigation, etc. I had to drive it on side streets to the closest dealer without aid of any standard dash meters.”

   NHTSA complaint #11632627, filed 2024-12

   “When approaching sunset, or when travelling under bridges, the dash dims excessively and is barely readable. I have to take my eyes off the road for extended periods of time to be able to see the information. The excessive dim does not reset itself, when the ambient lighting returns to normal, for a prolonged period of time. Complaints to the dealer service department, GM EV Concierge, and OnStar have not had any effect on resolving this. Tnis is an ongoing problem since delivery of the vehicle.”

   Electrical system

   High-voltage system and charging faults after updates

   • 19 complaints (17%)
   • typically at 1.7 yrs old
   • 1 mention a crash, fire or injury
   • filed 2024–2026

   Owners report service high-voltage warnings, failure to DC fast charge, loss of cabin heat, and repeated OTA updates that either did not install or left the car worse afterward. Complaints describe dealers confirming the fault but having no part or repair available, with vehicles sitting for weeks. Reported across the sample, most often shortly after a software update rather than at a specific mileage.

   4 related service bulletins

   What to check: Check the vehicle's update history and ask whether all outstanding over-the-air and service updates have installed. Test a DC fast charge session and confirm the cabin heater works before buying.

   2 excerpts from owner complaints in NHTSA records

   “We own a 2024 Cadillac Lyriq EV. We began experiencing safety concerns related to battery performance and overall vehicle reliability during the active bumper-to-bumper warranty period. These concerns were reported to an authorized GM dealer, Napleton Cadillac, prior to warranty expiration. Service records at Napleton Cadillac document the history of these complaints. The vehicle has been unable to process required over-the-air (OTA) software updates through GM's intended automated update process. …”

   NHTSA complaint #11725923, filed 2026-03

   “The vehicle is a Cadillac Lyriq. Following an over the air software update pushed by the manufacturer, the vehicle began displaying a high voltage system error message and lost the ability to DC fast charge. The high voltage components themselves are reported to be functional, the issue appears to be caused entirely by the software update rather than a hardware failure. The vehicle has been at an authorized dealership service center since August 14, 2026, awaiting a resolution. …”

   NHTSA complaint #11761303, filed 2026-09

Buying note. Ask for the full service and recall history, confirm the ABS and display recalls are closed with documentation, and verify the software is current. A thorough test drive covering reversing, one-pedal braking, a fast-charge session and the heater is worth the time on this model year.
