Top 8 Cadillac Issues
Has your Cadillac been in the shop more than once for the same problem? Start with this list.
Auto manufacturers sometimes release faulty cars, trucks, and other vehicles to the public. Unfortunately, Cadillac, a division of General Motors, is no exception. Owners of Cadillac vehicles, particularly Escalade models, have been reported to experience the following issues:
- Transmission Failure
- Oil Leaks
- Engine Failure
- Check Engine Light Turns On
- Vehicle Dies While Driving
- Hard Down Shifting (GM has recalled certain Escalades with the 10-speed automatic for harsh shifting)
- Brake Pedal is Stiff
- Vehicle Stalls While Driving
Should these symptoms or any other vehicle problems repeatedly appear, your Cadillac may be a lemon. Contact Lemon Law Help to talk with an attorney about your Cadillac lemon law rights.
Cadillac 6.2L Engine & 10-Speed Transmission Issues
Many Cadillac owners have reported significant issues with the 6.2L L87 V8 engine, commonly found in recent model year Escalades and other GM vehicles. This engine has been linked to catastrophic failures, including sudden engine seizures, excessive oil consumption, and unexpected engine shutdowns while driving. These defects pose serious safety risks and can leave drivers stranded.
In 2025, GM recalled certain 2021–2024 Escalade and Escalade ESV models with this engine because the connecting rod or crankshaft may have manufacturing defects. Based on an inspection, the dealer repairs or replaces the engine or switches it to a thicker oil. GM’s recall letter says GM then covers an engine failure from this defect for 10 years or 150,000 miles, whichever comes first, under the terms of the powertrain warranty.
In addition to engine problems, Cadillac Escalades equipped with General Motors’ 10-speed automatic transmission have exhibited harsh shifting, gear slipping, and complete transmission failure in certain cases. Drivers have reported erratic acceleration, hesitation when shifting gears, and abrupt power loss, which makes the vehicle unpredictable and unsafe to drive. Complaints point to internal component failures.
GM has since recalled certain 2021 and 2022 Escalades with this transmission because a worn control valve can cause harsh shifting and can make the rear wheels lock up. The dealer installs software that watches for valve wear, and GM’s recall letter says GM covers that valve wear for 15 years or 150,000 miles, whichever comes first.
If your Cadillac is experiencing any of these persistent engine or 10-speed transmission issues, you may have a lemon under California law. Contact Lemon Law Help to explore your legal options.
Cadillac Lemon Law Litigation
If your Escalade has lost power or its engine has failed on the road, other owners have reported the same thing.
Recent litigation over the 6.2L L87 V8, which GM uses in 2021 and newer Escalades, includes proposed class action lawsuits against General Motors. A federal court in Michigan combined twelve of them into one case in August 2025. As of October 2026, that case is still open.
GM’s recall documents and NHTSA complaints describe problems such as:
- Knocking, banging, or other unusual engine noises
- Sudden loss of power while driving
- Engine failure even after the recall repair
GM says an engine failure while driving makes the vehicle lose propulsion, increasing the risk of a crash. NHTSA has opened an investigation into engine failures in Escalades and other GM models with this V8, including failures after the recall repair. The California lemon law requires the manufacturer to replace or buy back a new vehicle with a warranty defect it can’t fix after a reasonable number of attempts, and you can choose the buyback.
If your Cadillac has recurring issues like these, you may qualify to receive monetary compensation or other remedies under California lemon law. Contact Lemon Law Help to explore your legal options.
