2025 Cadillac Lyriq problems

VEHICLE SPEED CONTROL

The contact owns a 2025 Cadillac Lyriq. The contact stated that while driving approximately 45 MPH on a four-lane highway with the cruise control deactivated, the vehicle unintendedly accelerated. The contact stated that the vehicle accelerated above 100 MPH. During the failure, the cruise control erroneously activated but the speed was not displayed. The contact attempted to stop the vehicle by depressing the brake pedal but it accelerated instead. OnStar was contacted for assistance and moments later the vehicle decelerated and was driven to the shoulder. The contact stated that the vehicle travelled approximately 3 miles before the vehicle decelerated. The contact exited the vehicle, and there was smoke coming from the wheel wells and the brake pads. A tow truck was called to the scene, and the vehicle was towed to a local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 10,000.

FORWARD COLLISION AVOIDANCE: WARNINGS

I was driving on the freeway and was between two cars. The car on my right was trying to merge into me. I immediately was breaking while trying to control steering. I attempted to honk three times and my honk horn would not work. In a case of an emergency, that is absolutely unacceptable a car like this should be able to honk.

POWER TRAIN

Stopped at the West Bound Thruway Seneca service area. After returning to the vehicle, multiple error messages were displayed on screen. "Have Power Steering Serviced, Service Stabilitrak, Service Headlamps, AWD Tempoarily Unavailable" Steering was the main issue. It was almost impossible to turn and steer. It was fortunate that it was after a stop and not while driving. The vehicle was towed to the dealer but it has yet to be determined why the steering failed.

ELECTRICAL SYSTEM

OnStar system on the vehicle is busted. Because of this the accident detection no longer works and the GPS is stuck in no mans land which makes it impossible to use their app to figure out charging percentage, how far and route to take to the nearest charging station.

ELECTRICAL SYSTEM

Car has been asleep after parking and will not wake up leaving all electrical components dead. GM has not been able to repair and unfortunately this has occurred 5 times including twice the month of March, 2026. Having a car parked in an unsafe location and not being able to move it very unsettling. After 30-60 minutes the car will start back up and operate normally.

FUEL/PROPULSION SYSTEM

My car is equipped with a forward-facing camera, mounted on the forward area of the interior rearview mirror. Additional cameras are mounted on the front bumper, trunk door, and on the rearview mirrors on each side of the car. Various sensors mounted throughout both bumpers face the front, rear, and each side of the car. At the time of this incident all sensors and cameras were clean and free of obstructions, and software was up to date. I was driving uphill, negotiating a tight left curve at approximately 30 MPH in a rural, forested area in the Santa Cruz Mountains (California.) There were no other conveyances, objects, or obstruction on the roadway in front or behind me. The weather was clear and the daytime visibility was excellent. The road was dry and I estimate its gradient at 30%. As I was about to enter the curve, the vertical dirt hillside appeared ahead and directly in front of the forward-facing cameras and sensors, which I supose, detected this topography. With minimal pressure, I had my right foot on the throttle to keep the aforementioned speed while turning. The cruise control was not in use. As I began to turn, and while still facing the hillside, the throttle stopped responding and the car decelerated. Simultaneously, a warning appeared on my dashboard screen, indicating the forward collision warning system was unavailable. I fully depressed the throtle but instead of gaining speed, the car slowed down to 12 MPH as I completed the turn. In quick succession, I lifted my right foot of the throtle and depressed it all the way to the floorboard but the car did not accelerate. The car eventually regained forward acceleration when I had the throttle pedal all the way against the floorboard but despite this severe throttle application, the car only accelerated very slowly. Thereafter, the throtle resumed normal operation and I continued my trip over the hills and back. I believe I could have been rear ended during this scary incident.

ELECTRICAL SYSTEM

Telematics module failed and the vehicle couldn’t connect to emergency OnStar services if involved in crash. GPS also doesn’t work with a faulty module. No cellular or WiFi connectivity. Car reroutes to somewhere without this module working. I’m paying for the OnStar subscription but with a faulty module it can’t connect. GM says part back ordered with no ETA. Thousands of people are reporting the same problem and it should be a recall at this point.

VEHICLE SPEED CONTROL

I was driving about 40 MPH, message popped "camera blocked, clean front windshield" I did and the message cleared. A few minutes later it came back so I cleaned the windshield again. What happened next shocked me. Without any warning while traveling 30 mph the automatic braking system came on and stopped the car quickly. Thank God for my seatbelt! My backpack that was in the back seat came flying to the front. No warning at all! I called the dealer and brought the car t them. They told me they need to load new software in the car that would take 5-6 hrs. They did the software and told me that it should be all set now. I picked up the car and drove it home. A few days later an incident more alarming happened! I was at a traffic light, car stopped and auto hold when suddenly the car accelerated on its own. I pumped the break several times and the car eventually stopped. I was terrified. I called the dealer and brought the car there the next morning. Dropped it of Saturday morning. I call Monday afternoon and spoke with the service person and he told me they could not replicate what happened and that there were no bulletins from Cadillac. I asked how they tested it and he told me they took it for a ride and also looked for any errors recorded in the cars memory. I said it happened to me once in 2 days so taking it for a short ride will not necessarily repeat what happened. He said they will hold the car and look at a few more things today. I just spoke to the dealer and they told me they drove the car for 15 minutes and found no issues. They also said they are looking for any bulletins on the car. Not sure what the outcome will be but these 2 incidents could have both been very ugly and people could have gotten very hurt. I ask myself...should I be driving this car!

WHEELS

I purchased the 2025 Lyriq new on May 11, 2025. On May 30th with 5400 miles on the car, the front right wheel tie rod snapped off while driving causing the wheel to turn sideways. I was making a turn on a secondary sheet when it happened and was able to pull to the side of the road. Had I been driving on the highway at the time, I could have been killed or hurt another driver. I had the car towed to MacMulkin Cadillac on June 1. The dealership noted that it was bad welding and the car showed rust and rot in that area. It will be 30 days this Monday and no one from GM has been out to investigate.
