What owners report
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 25V
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?
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 gmâs bulletin is the solution. Now I have to pay
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.
Engine and transmission for the second time in 90 days apart. Supposedly be a new part. I donât think so.
