2024 CADILLAC LYRIQ Complaints

I purchased a brand new Cadillac Lyriq on July 1, 2024, and have encountered several severe issues that compromise the safety and reliability of the vehicle: 1.Display Failure: The display frequently flickers, flashes, and sometimes completely blacks out, causing the loss of critical information such as speed, backup camera, navigation, and other vital systems. This makes the vehicle unsafe to drive, as it is impossible to monitor speed and other essential functions necessary for safe operation. 2.Battery Overheating During DC Fast Charging: The vehicle’s battery consistently overheats during DC fast charging sessions, causing the charge rate to drop significantly (from ~190 kW down to 14-20 kW). This overheating issue not only drastically extends charging times but also raises serious safety concerns, particularly during long road trips in hot weather. The vehicle has repeatedly experienced these issues, making it unreliable for long-distance travel. 3.Charger Overheating and Instability During Home AC Charging: The home AC charger provided with the vehicle becomes excessively hot while charging the Lyriq. Additionally, the charging rate fluctuates erratically between 0-3 kW, further complicating the charging process. This overheating of the charger at home raises concerns about the safety of parking or charging the vehicle in my garage, as it may pose a fire risk. These issues have been reported to my dealership, who have attempted repairs without success. The problems persist, and the vehicle remains unsafe and unreliable for my family’s needs. I am deeply concerned about the potential for these issues to lead to more severe safety incidents if not addressed promptly.

The contact owns a 2024 Cadillac Lyriq. The contact stated while driving at approximately 3 MPH as she was entering her garage to park the vehicle, she depressed the brake pedal, however, the vehicle continued forward and crashed into a tool chest located at the back of the garage wall. The contact stated that the front of the grill and the front bumper were damaged and had to be replaced. The contact stated no warning light was illuminated. The contact stated that failure reoccurred when she was parking the vehicle in a parking lot. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the ABS system had failed and caused a loss of braking ability. The contact was advised by the dealer that the failure was related to NHTSA Campaign Number: 24V589000 (Service Brakes, Hydraulic). The contact had the recall completed at that time. The manufacturer was informed of the failure. The failure mileage was 3,000.

Cruising at 65mph in moderate mixed traffic when vehicle began maximum braking with no action from me and no forward obstacles. Several following vehicles had to take drastic evasive action to avoid collision. Very lucky this resulted in no injury or damage. Could have been much, much worse.

Right rear taillight and brake light fail to light intermittently. This is a known defect on many other Lyriqs. When this failure occurs, the vehicle is not compliant with state laws regarding having working taillights and brake lights, and could result in a moving violation ticket. Cadillac should be required to recall and repair/replace these lights.

I was driving the vehicle and it stopped in the middle of the freeway. Another incident happened while Kane changing and another while exiting . All three incidents caused a extremely hard braking which felt like a collision.

It happened two times to me I was driving and I lost acceleration power. I put the car on Park and back to drive and it still didn't help the only way to get it to drive is to restart the car

Vehicle engage emergency stop in forward direction for no apparent reason. Leaving dead stop 2nd car at traffic signal. Huge problem as may cause rear end collision. I have disengaged all auto brake features. Had previously already disabled reverse auto braking feature. I was at a residential intersection. Single lane each direction with left turn lane. I was the 2nd vehicle in line. There was a crosswalk however there were no pedestrians, bicycles, etc. in the crosswalk or on any sidewalks of roadways. The left turn green arrow illuminated and the vehicle in front began turning. I began to follow and reached no more than 5-10 mph when "bang", the emergency stop engaged. I actually thought I hit a pole or object. Terrifying for my wife in the passenger seat also. The vehicle behind us was able to stop in time, this time. However, drivers do not expect the vehicle in front of them to begin moving the emergency brake for no reason. This is a dangerous defect which must be addressed.

The contact owns a 2024 Cadillac Lyric. The contact stated that the brakes erroneously activated while attempting to reverse. The contact stated that the failure occurred only while it was raining. There were no warning lights illuminated. The vehicle was taken to the dealer, and it was suggested to deactivate the Back Over Prevention and Cross Traffic Alerts while attempting to reverse. The vehicle had not been diagnosed or repaired. The manufacturer was made aware of the failure by the dealer. The failure mileage was 145.

Driving my car on the highway at speeds of about 65, and the charging port door suddenly opens. When I slow down then the door closes on it own. Seems like the housing for the door isnt made tight enough to stay closed during highway driving.

We encountered consistent loss of or erratic headlight operation. The behavior was that lighting would simply fail on one or both sides of the car, often along two-lane roads with curves in the road where it is critical to judge distance to oncoming traffic. Other times the lights would dim and wash out the ability to clearly see the road ahead. The dealer has replaced the headlights three times already. An associated lighting module was also replaced more than once. Note that this issue is still present so we are unable to use the vehicle now after dark.
