While driving northbound on [XXX], south of Oklahoma City, at normal highway speed, at night, in the rain (on [XXX]), this EV lost all power to the wheels and the regenerative braking ceased to function. It appears that all flow of electrons from the batteries to the drive motors, and from the regenerative brakes to the batteries stopped. I still had dashboard lights, steering, and conventional brakes. I was able to safely coast to a stop on the highway shoulder. I set the parking brakes, put the -??transmission-?? into -??park-??, and turned off the power button. I then restarted the car, and all was normal again. I continued my drive from Austin, TX, to Evergreen, CO with no additional incidents, arriving on [XXX]. This is reminiscent of the -??blue screen of death-?? in old Microsoft desktop computers -?" fixed the problem by cycling the ON / OFF switch. Unfortunately, doing this when driving at 75 mph is less than ideal, and is a real potential safety problem.

While driving through Wisconsin on [XXX] with Super Cruise activated in 70MPH traffic the car provided me with driver's side collision warning failure notice and then a forward collision warning failure notice, but the car continued to be operating normally. A short time later a brakes overheating warning came on while the car still seemed to be operating normally and maintaining speed. I immediately disengaged the cruise control to check out the situation and the car instantly locked on the brakes, and we could see smoke and smell the burning brakes. I pulled to car to the side of the road, and we exited the car concerned there might be a fire coming from one of the 4 smoking wheels. The rotors were red hot. We remained a safe distance from the car until the brakes stopped smoking. After it appeared safe, I reentered the car and determined the brakes (parking brakes) were fully engaged and the car would not move. We contacted OnStar for assistance and waited. After a significant time (it seemed like quite a while) I suddenly heard the sound of the parking brakes electrically releasing. Shortly after that I started and tested the car again and it would move so we slowly drove it off the busy interstate to the next exit a short distance away and continued working with OnStar to obtain a tow to a Cadillac dealership. After working with OnStar for several hours and determining that there would most likely be no tow truck coming, we decided to test drive the car around the area now that the brakes had cooled off. We ended up renting a 'safety' car that my wife would drive, and I would try to drive the car back to Minnesota to our dealer. The car operated normally for the drive home, but we did not use any cruise control just in case. It was my belief that a system communication issue told the brakes to engage and that since the Super Cruise was engage the motors just added more power to over-come the drag on the brakes until they over heated.

When approaching a red light at 5-10mph, I engaged the brakes, but the brakes did not work and the automatic breaking didn't work either, leading me to rear end the car in front of me. There were no prior warnings lights or notices, and the breaks were working properly before and after the accident. The car was towed to the dealership for inspection, but they could not find anything wrong and have contacted GM for further inspection.

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. After some time when I felt safe returning to the vehicle I turned it back on and was still showing breaks were overheated message and then was forced to get the car towed and take an Uber home. The vehicle is only 2 months old with ~3300 miles on it. The vehicle is currently sitting at the closest dealership to the event and they are unable to work on it due to a lack of EV service provided there and they told me they are unable to have it moved to the dealership I purchased it at.

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.

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.

Without warning and while driving this vehicle on expressway, I've received the following notifications several times: "Brake Failure" (car brakes on its own); "Service Stability and Auto Hold"; and "High Voltage" and Battery. Brakes, speed, steering, parking systems and camera do not work properly. Car's capacity to drive vehicle safely is reduced significantly - speed to drive car is immediately reduced and is limited without warning. Car shakes passengers violently (whiplash) when it believes there are people or objects in its path when there is nothing there and does not work properly when pedestrians are around the vehicle. During the incidents both my safety and other drivers safety are at risk - I am afraid to drive this vehicle although the dealership has indicated they have corrected the errors.Vehicle purchased 23 Oct - problems began around 2300 miles and have continued thru 4200 miles.

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.
