2024 CADILLAC LYRIQ Back Over Prevention Problems

The contact owns a 2023 Cadillac Lyriq. The contact stated that while reversing and proceeding to make a U-turn, he crashed into a steel guardrail. The automatic braking system did not engage. There was no audible or visual alert or warning provided by the system. There was no injury, police report, airbag deployment, or fire. The vehicle was taken to the local dealer. After twelve days, the vehicle was not diagnosed or repaired. The manufacturer was contacted, who confirmed the vehicle had functioned as designed. The failure mileage was 8,600.

Mileage: 8,600

When it rains, just a steady rain, not a downpour, the vehicle slams on the brakes trying to back up. It literally took 3-4 minutes to back out of the driveway. I was also in a parking lot trying to back out and the same issue which created a significant safety hazard with other vehicles. Research online indicates this is not an isolated issue.

Ref: NHTSA ID# 24V589/ GM Recall N242453471 Record shows that the above recall was completed on August 27, 2024. Yesterday while I was reversing my 2024 LYRIQ out of my garage I experienced multiple false automatic braking. Braking was so frequent that, I thought, driving that car at that time was unsafe and pulled it back into the garage and took my other car. It was raining at that time. False braking has happened in the past but not to a point where driving is nearly impossible.

Each time it rains and the car is in reverse, the emergency braking system kicks in repeatedly, and a red light flashes on the screen. The car believes there is an object or person behind the car; I would imagine because the rear camera can see the rain. It is difficult to even move the car at all, and is a major safety concern. The last time this occurred, I was backing out of my driveway at a slow speed. This also occurred backing out of a parking spot at a slow speed. I hesitate to drive this car in rain because of the issue. In speaking with the dealership's repair personnel, this occurs on every Lyriq. In fact, there was another Lyriq in for that complaint at the same time. I cannot attach photos or a video, as doing so would be unsafe. However, it can be easily re-created in any Lyriq.

Continuing problem with both front and rear emergency braking. Primarily when it is raining and vehicle is put in reverse violent and unexpected emergency braking will occur for no apparent reason. This will happen several times. Also, when backing out of driveway on a slant, rear emergency braking seems to sense the street and brakes are applied violently. This situation has also happened going into driveway on a slant for front emergency braking. Have informed the dealer several times of this problem and they say that Cadillac has not fix. Very distressing and dangerous for whip lash of adults and children.

I have had two incidents with the automatic braking system occur in a short period of time. The Lyriq is not a car that I drive very often so when the incidents occurred in the last 2 of the 3 times of driving the car it makes me scared to drive the car again. The first incident occurred while driving at approximately 35 mph. The road I was on had 4 lanes with a turn lane in the middle dividing the 4 lanes with 2 lanes on each side of the turn lane. The road carries moderately heavy traffic as it has many businesses (fast food restaurants, strip malls, etc.) I was driving in the left lane when a truck in the on coming traffic entered the middle turn lane and a vehicle ahead of me entered the lane to the right of me. Neither vehicle crossed the line of the lane I was in. This is normal traffic for the type of road I was on. I know there have been reports of rain interfering with sensors in the past, but this day was clear. My vehicle flashed a red collision warning and engaged the automatic braking system. This was scary as heck. It was very jarring to me and my passenger. Next incident I was parking along a curb. So this time I was driving under 10 mph. I was backing up and there was a hand rail along on a walkway on the curb. There was no way I would hit the railing as it was several feet from the roadway. There was no warning in my car when it engaged the automatic braking system. Even though I wasn’t traveling very fast it was very jarring and my neck was still hurting from the last incident when it engaged the automatic braking. When the car engages the automatic braking system it sounds as though it has hit something or someone has hit you. It’s very confusing. I reported previous incidents to my dealer and they said that the sensors were sensitive and they supposedly did some sort of fix, but frankly I’m concerned what could happen as these incidents have quite seriously been a pain in the neck for me.

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.

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.

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.

Mileage: 145

Car has a automatic back up braking system. The car will brake hard to stop vehicle if there is an object behind it. In this case, the car was braking when there was no object behind it. This happen continously while I was trying to back out of a parking space. I could only drive forward. Finally, after a few attempts to back out of the parking space, I was able to drive in reverse. After I was able to drive forward, I tested the the car drove to a location where there wasn't anything behind me. I put the car in reverse and it did it again automatically hard braked and stopped the vehicle. I waited then tried it again and I didn't have the problem anymore. I took the car to the Cadillac Dealer. I was told there have been others who have had this same issue. Furthermore, I was told they can't fix it. Perhaps the feature can be turned off I was told. I don't see where it can be turned off. The feature is a good safety feature if works when it should. Meaning, when there is truly an object behind the car. That's my complaint This was a scary episode.

The contact owns a 2024 Cadillac Lyriq. The contact stated that while reversing from the driveway, the brake pedal was applied without driver input. The contact stated that the vehicle detected an unknown object, causing the brakes to be applied, but the contact determined that there was no object behind the vehicle. While driving at 50–60 MPH, the brakes were applied without application. There were unknown warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The computer was reset. The vehicle was not repaired. The manufacturer was contacted, but further assistance was not provided. The failure mileage was approximately 100.

Mileage: 100

The automatic collision system braking is engaging when the vehicle is in reverse and while it is raining. This occurs multiple times while trying to back the vehicle up during rain. This is dangerous for the passengers since they are abruptly thrown backwards without warning. The vehicle must be placed in "park" and then "reverse" multiple times until the collision braking stops malfunctioning.

Within two month the Lithium ion battery failed twice. and the car was not derivable. It had to bet towed to the dealer.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components of our driver assistance software have failed, beyond what we can check in the fields above. Most recently, we have experienced two major failures. The first failure occurred when the car triggered the emergency parking brake on its own while we were driving in traffic at 30 mph. We narrowly avoided being rear ended. This is the incident I've detailed in the fields below. The second failure occurred when the adaptive cruise control failed to brake as we approached gridlock traffic. We again narrowly avoided collision on multiple fronts. We were going approximately 45 mph with roughly 2000 miles on the car. We have the service records, but the selling dealer and Cadillac engineering claim these issues are now fixed. How was your safety or the safety of others put at risk? We were well within less than a car length of collision in both of the situations described above. This car is a large SUV, it would presumably cause significant damage to cars it hit. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. They verified failures and out-of-date software in our vehicle in this last service visit. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This vehicle has been directly inspected by Cadillac engineering through our selling dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The warning lights we experienced included the warnings that the system had engaged and "service driver assist system." There was no warning when the adaptive cruise control failed.

Repeat issue from dealer repair. When sometimes car slams on breaks at 1 mph with nothing behind it. Can happen once or several times during this one time backing up. I pull forward and then back up again no issue. Also get a service parking brake error for no reason and goes away. Rear braking happen clear days sunny day and rainy days randomly

When in reverse abrupt automatic braking occurs. Safety hazard with abrupt stop around other vehicles, hard braking causes driver and passenger to pitch forward. No warning. Automatic Braking disabled, sensors checked, settings adjusted by dealer. Dealer says there is nothing they can do. General Motors contacted but no action taken to date.
