Sporty looks, modest punch
The Coupe RD looks sporty, but the smaller engines are a letdown in the real world.
Engine Weaknesses 5
The Beta G4GR has a timing belt with a 60,000 km service interval. If it fails, the valves bend. The belt does not always last to 60,000 km on some examples.
Symptoms: Sudden engine stop without warning; engine will no longer start; no compression.
Older Delta V6 engines tend to oil leaks at valve cover gaskets and camshaft seals at high mileage. Complex disassembly due to tight V6 installation.
Symptoms: Oil stains under the vehicle, oil smell in the engine bay, dropping oil level, smoke from hot exhaust manifold.
Beta engines frequently show oil consumption from worn valve stem seals and piston rings at higher mileage. Typical symptom: blue smoke when cold.
Symptoms: Blue smoke on cold start; elevated oil consumption; oil mist from crankcase ventilation.
Occasionally reported defect in the Beta cooling system: a sticking thermostat leads to overheating. Inspection combined with timing belt check is recommended.
Symptoms: Temperature gauge rises quickly into the red zone; heater blows no warm air (thermostat stuck open).
The Beta G4GR engine shows hydraulic lifter knock with oil starvation or long change intervals. Lifters do not tolerate poor lubrication.
Symptoms: Ticking and clattering from the valvetrain after cold start; can often be dampened with fresh oil.
Vehicle Weaknesses 3
The bonnet preferentially rusts at the top grip edge; the tailgate at its weld seams. Dark paint colours (black) show clear coat peeling and blistering earlier. Door bottom edges and drain holes are often blocked by dirt.
Window regulator mechanisms and motors fail frequently, especially on the rear doors. Plastic gears in the drive break at low temperatures or after heavy wear.
Leather seats in the trim variants show early cracks and creasing. The leather is not particularly high quality and is sensitive to sun exposure.
