The Toyota Corona, known for its reliability and practicality, has been a staple on New Zealand roads for many years. Whether you own a Corona TD or a Corona Premio, understanding potential issues and proper maintenance is key to keeping your Corona running smoothly. This guide compiles common problems, WOF (Warrant of Fitness) inspection points, and general maintenance advice to help you stay informed and proactive.
Owners often report the following issues in Toyota Coronas:
• Worn suspension components (shocks/struts, ball joints, bushings)
• Automatic transmission problems (harsh shifting, slipping)
• Engine oil leaks (pan gasket, valve cover gasket)
• Rear wheel arch rust (especially in coastal areas)
• Increased oil consumption in higher mileage vehicles
When taking your Toyota Corona for a Warrant of Fitness (WOF) inspection, remember to pay special attention to:
• Front lower ball joints (Corona TD/Premio TD)
• Brake pad thickness and condition of front brake hoses
• Functionality of the switch stop light
• Play in steering components
• Corrosion around suspension mounting points
• Headlight lens clarity and beam pattern
• Front lower control arm bushings
Here's a breakdown of areas to monitor and maintain for optimal performance and longevity of your Toyota Corona:
Braking System: Regular inspection of your Corona's braking system is crucial for safety. Pay attention to brake pad thickness and wear. Front brake hoses should be checked for any signs of leaks or damage during WOF inspections. Be aware that uneven brake pad wear can sometimes occur.
Filtration: Ensuring your filters are in good condition is essential for your Corona. Neglecting the cabin filter can lead to reduced airflow and other issues.
Suspension: The suspension system plays a key role in ride comfort and handling. Keep an eye out for signs of wear in shocks/struts rear and ball joints front lower. Front lower control arm bushings are also susceptible to cracking or excessive movement. Also be aware of potential corrosion around suspension mounting points.
Transmission: Transmission issues can arise, particularly in automatic models. Delayed or harsh shifting, especially when cold, can occur, especially after 150,000 km (Corona TD/Premio TD). Listen for slipping between gears, which could indicate problems, especially after higher mileage (around 180,000km on Allion/Corona Premio). CVT transmission judder and whine can also occur on some models from 120,000 km.
Engine: Engine oil leaks, particularly from the engine oil pan gasket (Corona/Corona Premio TD), are a common concern. Vibration at idle can mean worn engine mounts (Corona TD/Premio TD). Valve cover gasket leaks are also something to watch for (Allion/Corona Premio). Some models may experience increased oil consumption after 150,000 km (Corona Premio/Premio). Ignition coil failures around 100,000 km can also occur (Corona Premio/Premio).
Other Potential Issues: Owners should also be aware of potential rust development in the rear wheel arches, particularly in coastal areas, typically appearing from 180,000 km onwards (Corona TD/Premio TD). Headlight lens clarity and beam pattern should be checked during WOF inspections. Window regulator motor failures and dashboard plastic cracking from UV exposure are other potential issues (Corona Premio/Premio). Coolant system weeping is also possible (Corona Premio/Premio).
