FUEL/PROPULSION SYSTEM, ENGINE, VEHICLE SPEED CONTROL
While driving at highway speeds on the freeway in my 2021 Cadillac CT4-V, the vehicle experienced a sudden, catastrophic loss of propulsion. Without warning, the transmission dropped out of gear as if it were in neutral. I completely lost the ability to accelerate, creating an immediate, life-threatening hazard as I was left stranded and blocking high-speed freeway traffic. Only after the mechanical failure occurred did the check engine light illuminate. The vehicle was towed to Cadillac Dealership. The service department confirmed that the vehicle suffered from the known defective transmission control valve covered under GM Special Coverage Bulletin N242480631 and tied to NHTSA Campaign 25V148. The dealership ordered the replacement valve body but aborted the repair after confirming that the control valve's failure caused massive internal fluid leaks and total mechanical destruction of the transmission assembly. The manufacturer is currently denying coverage for the complete transmission replacement, despite the fact that the total failure was consequential damage directly caused by the federally recalled, component defect.

FUEL/PROPULSION SYSTEM
Check engine light for P1467 on a 2021 CT4 V. This is for a "purge pump underspeed" issue. The issue is known on CT4 Cadillacs and has an active recall out: N242441120 Evaporative Emissions Purge Pump. This recall is only for the 2.0, LSY engines, but the much more uncommon 2.7, L3B engine in my car uses the same part # for the purge pump. It feels as though they are intentionally ignoring an equal emissions issue, but just on a smaller scale with the limited number of these engines they sold. What actions can I take?

POWER TRAIN
There is a known issue with hesitation and hard shifting on my vehicle. According to the gm bulletin that was released I believe in may of 25 my year, make and model has a known issue where the transmission control valve may stick or wear causing jerking and shifting issues and could cause a possible crash. According to the bulletin by gm the fix is to replace the valve cover on the transmission. My vehicle is currently at the Cadillac repair center for this shifting issue and it has been diagnosed to need a valve cover replacement to solve the problem. My point is I have the exact problem listed in the recall and the exact repair listed on gm’s bulletin is the solution. Now I have to pay for the repair because my vin is not specifically listed yet but my year, make and model and problem and the solution is all listed . I know I’m apart of this recall please help me

UNKNOWN OR OTHER
It is hard to get in and out of the drivers seat of the Cadillac CT4 without hitting the rear hinge post of the back door. The steering wheel doesn't adjust up enough to clear enough space to get in without hitting your head on the top edge of the drivers side door frame. It shouldn't take contorting your body to get in and out of a car. If there was an emergency (ie: car caught fire) to exit the car, you wouldn't be able to in a hurry. I've tried my best to describe this nightmare.

valve body failed and was supposedly repaired. I had the car 1 day and valve body failed again. My car has been in the shop since November 4, 2024 with no estimated time of repair because no parts are available. I was told they would replace the transmission. That has not happened yet. No parts available. My car has been disable for 6 months.

VISIBILITY/WIPER
In November 2023 I purchased this vehicle. The dealership was made aware of the ripples within a few days of driving the vehicle. The windshield was defective and had to be replaced. The staff at the dealership did see the ripples on the windshield and agreed to replace the windshield. On December 14, 2023, the dealership replaced the original windshield even though they had the windshield since November 22, 2023. Within a few days of driving the vehicle, I noticed it also has ripples on the 2nd windshield. I have been to the dealership two times, and no one can see ripples. I have taken the vehicle to an automotive glass company who confirmed the ripples in the windshield. On February 5, 2024, I took the vehicle to a different dealership. The appointment was scheduled by a General Motors representative. The staff at the second dealership cannot see anything and took pictures to send to General Motors. The ripples in the windshield are distracting when driving in the daytime and nighttime.

SERVICE BRAKES, VEHICLE SPEED CONTROL, STEERING
The problem first arose in June 2023. I was driving and suddenly, all the dashboard lights went on and the brakes stopped working. There was no pressure on the pedal. I was able to roll to a stop without incident. I turned the car off and back on again and the brakes worked but the check engine light was still on. I was able to limp the mile back to my house. After almost 6 weeks at the dealer, I was told they replaced a brake module and the car was fine. On [XXX], it happened again. It was towed to the dealer and I refused to drive it again. The car had about 2400 miles on it. They took it back, although claiming nothing was wrong, and I bought the CT4V Blackwing 2023 VIN [XXX] . On [XXX], it happened in the new car (500 miles on it). The dashboard lit up, the brakes wouldn't work, although this time instead of no pressure on the pedal, it was hard as a rock. After turning it on and off again, the brakes worked but the speed was restricted and other things in the car did not seem to be working correctly. The check engine light was also on. The dealership towed it. They told me they could not recreate the problem. Weeks later, I was told that an engineer from GM was looking at it. I received a call from some customer support department person who eventually told me that there was nothing wrong with the car, that the brake failure was a result of the Allstate Milewise device that was plugged in and they would not do anything for me. My husband has a Milewise in his Chevy truck with no issues. I found a forum online discussing this problem which has apparently happened to numerous people in CT4V and Blackwings. I also spoke to Allstate which does not have any reported problems with the device. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
The vehicle shut off while driving on the feeder of the highway. Vehicle was no longer responsive and had to be towed to Central Cadillac of Houston; where later it was determined that the vehicle needed a new engine. The Vehicle is a 2023 with less than 5,000 miles on it. Currently General Motors/Cadillac is not acknowledging that a buy back is needed for the vehicle, even though it meets requirements for the Texas Lemon Law.
