Who Should Buy Cadillac vs Mercedes-Benz?
If you want the lowest chance of trouble, lean Cadillac. Target an XT5, and look for a 2019, which has no recalls on record. Ask about any "Steering Assist is Reduced" warning, which dealers often trace to a failed thermostat. On an Escalade, skip the 2021 because of sudden engine failure. The 2020 is the better pick, but listen for knocking or rough idle, which point to lifter and camshaft trouble.
If you prefer a Mercedes-Benz, stay with the SUVs. The GLB, GLC, and GLE rate good, and so does the E-Class. On a GLB, skip the 2020 and favor the 2022 or 2023. Ask for service history because some owners report cylinder head and valve failures. Be careful with the sedans. The CLA, C-Class, A-Class, and EQS all rate mixed. If you consider a CLA, choose a 2020, skip the 2022, and test for a transmission that drops into Neutral.
The Bottom Line: Cadillac or Mercedes-Benz?
For most shoppers, the safer used buy is a Cadillac, and the XT5 is the strongest single model across both lineups. Repair costs do not change that. Mercedes-Benz averages $8 a year less, about $40 over five years. Pick a Mercedes-Benz only if you want a GLB, GLC, GLE, or E-Class, and avoid its mixed-rated sedans.
