It is always difficult to write our famous Toyota Avensis common fault lists as these cars are known for their reliability. However, no vehicle is completely spared.
There are a few issues that concern the Avensis the most, so keep an eye out for the following failures when considering buying a used vehicle.
1- Problems with headlight condensation
You may have to get up very early in the morning to detect this problem. Condensation can accumulate on the headlights , especially in the cold hours of the day.
Fortunately, even if you do encounter this problem on a potential purchase, it’s fairly easy to fix. To fix this problem, you’ll likely have to disassemble the entire unit and replace it, which could be an expensive enough problem to take your eyes elsewhere.
2- Diesel particulate filter (DPF) clogged
The old diesel particulate filter clogs up pretty quickly on the Avensis. Too much soot in this part can lead to dulling and harsh driving, as well as a particularly pungent aroma wafting through the cabin of the car.
Fortunately, the main cause of this is often the owner not getting out on the road enough where the car can get up to speed to clean the filter. Check if the owner allows you to go out for about 10-15 minutes on the highway at more than 80 km/h and the problem may disappear.
3- Steering noise
One of the recalls that affected the brand concerned a common Toyota Avensis failure with the steering column, which caused a rattling noise when cornering. Most of the vehicles that suffered from this fault were picked up and repaired under warranty , but nonetheless, you should remain vigilant in case your potential purchase escapes this problem.
There is another problem with the steering rack that causes a squealing or knocking sound that is more severe, and requires a complete part replacement to fix.
4- Squealing brakes
The brakes make a screeching noise when applied . When the brake pads are heard, it is usually discovered that they are worn. Replace them immediately with new ones. You can also place anti-squeak pads, which will also help delay wear.
5- Slow start of the cold engine
The engine starting time is short when the key is turned in the morning or after the engine has cooled down.
In most cases this is due to faulty heaters. You will have to install new ones. If that doesn’t solve the problem, then it could be an electrical fault, and you’ll need a full diagnostic check.
6- EGR valve blocked
The EGR (exhaust gas recirculation) valve can become blocked, which will cause the following problems: You may notice a loss of power and/or black smoke coming from the exhaust and/or rough idling. You can unblock the EGR valve by cleaning it . You will have to disassemble it, clean it, and put it back to fix this problem.
7- Black smoke
Very black smoke coming out of the exhaust and the revs have dropped . Any car emitting black smoke is having an air-fuel ratio problem. There will be an imbalance, and it can be caused by a variety of different issues.
Check the injectors, the injector pump, the air filter, the intercooler, the EGR and the cylinder head. You’ll need to examine each part closely to identify any broken or worn parts, and replace them as necessary.
8- Problems with the airbag
The airbag has been deployed or can be heard making a noise . You will have to replace the entire airbag assembly. Any problem with the airbags must be resolved as soon as possible. However, it is often advised to leave airbag troubleshooting to the professionals because the assembly contains potentially harmful fuels and toxins.
9- Whistle when accelerating
There is a hiss when you step on the accelerator . This usually indicates that there is a problem with the turbo or with an intake pipe. Check that there are no holes in both. Make sure all intake tubes are securely fastened and tighten if they are loose. If you detect a hole, you will have to disassemble and change the corresponding part.
10- Long braking distances
It may take longer than it used to for the car to come to a complete stop . Check the service history of the car. The cause is usually an imbalance in the braking system. It was the subject of a recall on the Avensis, so the work should have been done by now. If not, a Toyota dealer should perform the repair free of charge. If they don’t, you’ll have to replace the entire brake system.
