2021 Cadillac CT5 Recalls, Ratings & Complaints

Incident: September 1, 2026 · Filed: October 14, 2026

This vehicle is equipped with electronic door handles that are failing widely and prematurely. Essentially the button that actuates the cylinder to allow the door to open fails. This poses a safety risk as you're unable to open the door from the exterior in the event of an emergency. Imagine if you were in a collision that resulted in a fire and you needed to be able to retrieve a young child from the vehicle but the door won't open. This is a lawsuit waiting to happen. Manufacturer doesn't care to address the concern with a recall, but rather offers to repair at an astronomical price tag. The problem appears suddenly with no warning.

The Cadillac CT5 door handles are operated via a button instead of a typical pull style handle. The buttons fail regularly meaning you cannot open the specific door(s) where the button has failed. With small children in the car when this fails it poses a severe health and safety risk. There needs to be a recall issued for this well known and documented problem.

I am filing a formal safety complaint against General Motors (GM) regarding an unresolved transmission safety hazard on my 2021 Cadillac CT5 550T. This vehicle is included under NHTSA Campaign Number 25V148000 for an internal transmission control valve failure that can cause sudden, dangerous wheel lock-up while driving. My vehicle is currently experiencing an active, catastrophic failure of the transmission valve body. The vehicle has completely lost its reverse gear, shifts harshly, and exhibits Diagnostic Trouble Codes P0776 (Pressure Control Solenoid B Performance/Stuck Off) and P0700 (Transmission Control System Malfunction). These active fault codes and physical mechanical symptoms explicitly confirm a dangerous loss of hydraulic pressure directly resulting from the exact internal valve wear described in the federal recall. General Motors has issued Special Coverage Bulletin N242480631 to extend the warranty coverage on the physical transmission control valve body assembly to 15 years or 150,000 miles to address this exact defect. However, Cadillac Customer Assistance and the local dealership are refusing to pay for the required replacement component. They have denied coverage solely on the grounds that electronic fault code P0747 has not yet been registered by the computer, despite total mechanical failure of the component and a severe safety risk to the vehicle occupants. GM’s reliance on a singular electronic diagnostic code to trigger a safety-critical mechanical component replacement creates a severe hazard. It forces vehicle owners to drive an unstable, failing vehicle with sudden wheel-lock vulnerability while waiting for a secondary electronic flag to trip. I am requesting that the NHTSA review GM’s restrictive diagnostic criteria under Special Coverage N242480631, as it is being used to systematically deny repairs for vehicle owners actively suffering from the mechanical failures governed by Safety Recall 25V148000.

I have experienced a serious and recurring safety issue with the door handles on my Cadillac CT5 vehicles. The exterior door handles have stopped working, preventing the doors from being opened normally. On one occasion, I was trying to get my child out of the back seat when the rear door handle failed and would not open. Because the child safety lock was engaged, my child was also unable to open the door from the inside. I had to climb through the vehicle and use another door to get my child out. This situation is especially concerning because, in an emergency such as a collision, fire, or other situation requiring immediate evacuation, a malfunctioning door handle combined with the child safety lock could prevent a child from exiting the vehicle and could significantly delay a parent or caregiver from getting them out. I have two Cadillac CT5 vehicles, and this same issue has occurred on both vehicles. I have also been told by Cadillac dealers that the door-handle failure is a known problem. Despite the recurring nature of the issue, I understand that Cadillac has not issued a recall for the door handles. Instead, individual door handles must reportedly be replaced every two to three years, with repair costs ranging from approximately 400 to 1,000 depending on the door. I believe this issue warrants serious attention because it involves a potential safety hazard, particularly when a child is secured in the back seat with the child safety lock engaged. A component that can prevent a vehicle door from being opened during an emergency should be reliable and durable, and recurring failures across multiple vehicles raise significant safety concerns.

The exterior door handles on my 2021 Cadillac CT5 have experienced the same intermittent failure. The handles initially work intermittently and then become unable to release the door. The button on the inside of the door handle doesn't respond when pushed and that is the only way to get in the car without rolling the windows down or using the emergency key. I've seen many other forum posts about this so it seems to be a widespread issue across other models with the same electric door opener mechanism. This creates a serious safety concern for me because occupants may be unable to enter the vehicle normally, and emergency responders may be unable to access occupants through the affected doors. This appears to be a systemic defect affecting multiple CT5 vehicles, rather than an isolated component failure.

Doors have routinely stopped opening using the electronic handles to pop open doors. Have taken to dealership to repair, but keep on not working on other doors. All 4 door handles have been replaced and now they're starting to not work again.

Both front doors will no longer open from the outside. The button on the inside of the door handle doesn't respond when pushed and that is the only way to get in the car without rolling the windows down or using the emergency key. I've seen many other forum posts about this so it seems to be a pretty widespread issue across other models with the same electric door opener mechanism.

All four exterior door handles on my 2021 Cadillac CT5 have experienced the same intermittent failure. The handles initially work intermittently and then become unable to release the door. This has occurred on all four doors. This creates a serious safety concern because occupants may be unable to enter or exit the vehicle normally, and emergency responders may be unable to access occupants through the affected doors. This appears to be a systemic defect affecting multiple CT5 vehicles, rather than an isolated component failure.

The pump gear on the transmission went out during normal driving with only having 30,000 miles on it. I am told my numerous people that the Gm 10 speeds always have issues with them.

The door opening mechanism has failed on the drivers outside door handle. It locks and unlocks fine but it will not open. I can use an alternative by the getting the emergency access key out of the fob and popping off the handle and open with that key. Or I can go in thru another door and open it from inside or somehow open all the windows using the fob with some kind of press this and that at the same time, and access inside handle thru the window. This becomes a safety concern because I'm usually alone, and this makes me vulnerable when I have to get into the car. Especially in parking lots and garages or gas stations, or anytime there may be a situation where a quick get out of there may be required. I have been visiting the Cadillac forums and have heard many of this same complaint in the on-line discussions. Many of the complaintants have recommended to report the as a safety concern. There is no warning of this in the systems, nor is there any information coming from Cadillac about resolving this problem in the
