2021 Cadillac CT5 Electrical System Problems

The passive door locks on the handles to the car do not work. The electronic sensor to unlock the car does not work due to misalignment of the pin that is supposed to press the key. This is a widely known issue on 2020-2021 Cadillac ct5 vehicles. This eventually results in total lockout of the vehicle. I currently have three doors that do not unlock. Please see a link to the issue I reported on Cadillacs form website as well https://www.cadillacforums.com/threads/door-handle-issues.1141023/?nested_view1#post-18436706

I've had my driver side door handle switch replaced beacuse it was faulty and I could not get into my car through the driver side. Now I am having the same issue with the passanger side. In a case of an emergeny if I can not get into my car I fear for my or my passanger's safety. I fear the quality of the parts are not ment to last. I replaced the driver side handle right before the manufactur warreny ran out then the passanger door stopped working when the warrenty ran out.

The door(s) would not open from the outside. I had the driver side door handle replaced first - took weeks for the part to come in - this was a safety issue because I had to climb through the passenger side to open the driver side door. (the key entry would not work either) After weeks, and me paying for it, the same thing happened to the rear driver side door. I went to open it to get my grandchild out and couldn't. Again this is a safety issue. What if I needed him out in an emergency and I couldn't. I had to walk around and get him out of the car on the other side. Now my passenger door is broke. This is a big concern, which I let the dealership know about, the safety if you can't get someone out of a car or just getting in your car - a person is vulnerable to outside elements/surroundings. The dealership has said this is a very common problem with this make/model. If "very' common it should be recalled. They shouldn't be waiting for something bad to happen prior.

Driver Side door handle stops working. Because the door handle operates with a sensor and not a standard pull door handle something is being affected and it will not open door. Causing safety issue and not being able to enter car normally.

When approaching a stopping vehicle the brake pedal became extremely hard to press and I could not brake enough to stop and had a collision. Come to find out that the ABS computer and the main ECU weren't communicating correctly which turned off the assisted braking, assisted steering and the AWD.

The exterior door handle latch release switch fails to open the door. This issue happened to all 4 exterior doors. The problem starts with intermittently, then progresses to complete failure. Once it fails, the entire door handle needs to be replaced. If all 4 doors fail, the only way to access the car is with the Emergency Key or if you activated the Remote Window Down. This only works if you have access to the key. If you left your keys in the car, the car would lock (even if running) then your only option is to fiddle with the switch in hopes of activating it or crawl through the trunk (if you're small enough). If an infant or a pet is in the car, then that could lead to problems. Also if you pass out and emergency responders came out, they would have to break the window or pry the door open to gain access, which could pose a life or death situation. This is a well documented issue with this car per the Cadillac Forums. I replaced both the front door handle assemblies to repair the main access to the car. The rear handles are still inoperable. During inspection of the Handle Electronic assembly, it appears that the switch isn't fully seated against the circuit card, which causes the solder connection on the circuit card to fail.
