2023 Cadillac XT4

The 2023 Cadillac XT4 is a compact luxury SUV offering a blend of style, technology, and practicality. It comes standard with a turbocharged 2.0-liter four-cylinder engine, producing 235 horsepower and 258 lb-ft of torque, paired with a 9-speed automatic transmission. Known for its comfortable ride, user-friendly infotainment system, and spacious interior for its class, the XT4 is often praised for its value proposition. However, some common criticisms include its somewhat uninspired engine performance compared to rivals and occasionally less-than-premium interior material quality.

Engine

2.0L Turbocharged I4 (LSY)

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher-than-normal oil consumption, requiring more frequent oil top-offs between scheduled oil changes. Symptoms include the low oil pressure light illuminating, the need to add oil frequently, and in some cases, bluish smoke from the exhaust.
  • Solution: In some cases, a software update of the engine control module (ECM) might help to optimize fuel injection and combustion, potentially reducing oil consumption. If the consumption is severe, it could point to piston ring issues, requiring engine disassembly and repair or replacement.
  • Estimated Cost to Fix: $100 (software update), $3,000 - $8,000+ (engine repair/replacement)
  • Recalls: None Found
• Turbocharger Issues
  • Description/Symptoms: Some owners have reported turbocharger failures resulting in loss of power, unusual noises (whining, whistling), and diagnostic trouble codes (DTCs) related to turbocharger performance.
  • Solution: Diagnosis and replacement of the faulty turbocharger.
  • Estimated Cost to Fix: $1,500 - $3,000+
  • Recalls: None Found

Transmission

9-Speed Automatic (9T45)

• Harsh Shifting/Hesitation
  • Description/Symptoms: Reports of rough or jerky shifting, particularly between lower gears. Hesitation or delay when accelerating, especially from a stop or during passing maneuvers. Some have noticed this more in cold weather.
  • Solution: A transmission control module (TCM) software update may resolve shifting issues. In more severe cases, valve body replacement or transmission replacement may be required.
  • Estimated Cost to Fix: $100 - $250 (software update), $800 - $1,500 (valve body replacement), $3,000 - $6,000+ (transmission replacement)

Electrical

• Infotainment System Freezing/Crashing
  • Description/Symptoms: The Cadillac User Experience (CUE) infotainment system may freeze, become unresponsive, or crash unexpectedly. This can affect navigation, audio, climate control, and other functions.
  • Solution: A software update for the CUE system might address stability issues. In some cases, a system reset or replacement of the infotainment control module is required.
  • Estimated Cost to Fix: $0 (software update if under warranty), $500 - $1,500+ (control module replacement)
