All Known Issues

EGR Valve and Cooler Clogging & Head Gasket Failure

SeriousEngine

At high mileages, carbon buildup in the EGR system can restrict flow, leading to increased cylinder temperatures and eventually blowing the head gasket. This is the most common major engine failure on high-mileage CT200h cars.

Est. Repair Cost: £300–£2,500
Warning Signs:

Loud knocking sound on cold start, Rough idle, Coolant consumption, Check engine light with P0401 code

What to Inspect:
  • Listen for any unusual rattling when the petrol engine kicks in
  • Check for "mayonnaise" under the oil cap
  • Confirm no white smoke from the exhaust on startup

Rear Brake Disc Corrosion

MinorBrakes

Due to regenerative braking, the rear discs often don't get "cleaned" by the pads, leading to surface corrosion and pitting that causes MOT failures.

Est. Repair Cost: £200–£400
Warning Signs:

Squealing when braking, Visible pitting or rust on the disc surface, Advisory on MOT for "discs pitted"

What to Inspect:
  • Inspect the rear discs through the alloy wheel spokes
  • Check for a "lip" on the edge of the disc
  • Feel for any pulsing through the brake pedal

Buying Tips for 2011 Lexus CT 200h

  • ✓Ask if the EGR valve and cooler have ever been cleaned. If the car shakes on startup, this is a likely culprit.
  • ✓Check the 12V auxiliary battery (located in the boot). If it's original and over 5 years old, it may be near the end of its life.
  • ✓Test the ride quality; the F-Sport models have significantly firmer suspension which may be too harsh for some UK roads.
