Engine & Performance

1. Engine Seizure or Failure

What Happens: The engine's internal components, such as pistons and crankshaft, seize and lock in place. This is often due to a complete lack of lubrication, and the engine will not crank or turn over. If it occurs while driving, the vehicle will stall and cannot be restarted. It is one of the prominent Cadillac car issues.

Affected Models: Escalade (2015-2025), CTS (2016-2019), CT6 (2016-2020), Lyriq (2023-2025 for EV variants with battery-related failures).

Symptoms:

• Sudden loss of engine power, causing stalls even at high speeds.

• Preceding ticking, knocking, or unusual engine noises.

• Dashboard warnings like the check engine light or reduced power mode.

• In EVs like Lyriq, battery pack malfunctions leading to towing needs.

Common Causes:

• Lifter collapse or defects in Active Fuel Management (AFM) systems in gas engines.

• Manufacturing flaws in crankshaft/connecting rods, per 2025 recalls.

• Oil starvation, blockages, or vacuum leaks exacerbate wear.

• In Lyriq, battery module failures or software glitches can interrupt power.

Impact:

• Severe safety risks, including highway strandings or crashes from power loss.

• Extended downtime, with repairs taking weeks due to parts backorders.

• High costs post-warranty, potentially totaling vehicle value in severe cases.

• Reduced resale and owner confidence, as seen in class actions.

Solutions:

• Conduct dealer diagnostics and apply software updates or recalls.

• Replace faulty lifters, valves, or entire engines in gas models.

• For Lyriq, battery inspections or replacements under warranty.

• Monitor for GM bulletins and claim the lemon law if recurrent.

Estimated Repair Cost: AED 18,000-37,000 (diagnostics: AED 370-730; lifter swap: AED 7,000-15,000; full engine: AED 18,000+).

Prevention Tips:

• Adhere to 5,000-7,500 km oil changes with synthetic fluids.

• Regularly check oil/coolant levels and address warnings promptly.

• Avoid cold aggressive driving; use premium fuel to cut deposits.

• For EVs, ensure software updates and avoid extreme temperatures.

2. Fuel System Problems

What Happens: The hydraulic pressure or internal friction components of the transmission fail to engage or disengage gears smoothly. This results in a pronounced jolt, shudder, or delayed shift as the transmission struggles to transfer power.

Affected Models: Escalade (2015-2020), CTS (2016-2019).

Symptoms:

• Rough idling that feels unsteady at stops.

• Hesitation or lag during vehicle acceleration.
