Toyota Corolla 2018 Problems

Using a trim removal tool lever the trim around the screen out of the dash. Pop it forward, then unclip the hazard button and wiring for the airbag light. Undo four 10mm bolts at the edge of the unit. Slide the unit out, disconnect the wiring and it is out.

The Ascent, SX, ZR and Hybrid models use a 205/55-16 tyre, while some SX models were available with a 215/45-17. If in doubt, check the writing on the side of your tyre for either of those numbers.

The first things to do would be lower the suspension, fit some aftermarket 18 or 19-inch wheels, tint the windows and try finding a lip spoiler for the front. Of course, you need to have this work done by a qualified professional and check it is legal before starting work.

Lifting the suspension of a Corolla won't help improve how it drives off-road. Toyota already sell a Corolla-sized vehicle with higher ground clearance, called the RAV4. Buying a RAV4 will save you navigating re-engineering the suspension on the Corolla with a factory perfect model.

In a current-generation Corolla you need trim removal tools (which are easy to purchase at any local parts store, or via the Internet). Start by levering the top right corner of the radio fascia piece outwards from the dash. It is retained by plastic clips that simply pop out so don't be afraid to give it some oomph. Once you have it loose you can unplug the wires attached to the back of it. There are then four 10mm bolts holding the radio unit to the dashboard, positioned around the top and sides, towards the rear of the unit. Use a long 10mm socket on an extension, fitted to a ratchet handle, to remove these. You can then slide the radio unit forward and unplug it.

While you can change the indicator, parker and high-beam bulbs in a current-generation Corolla, the low-beam is sealed into the headlight housing that means it has to be replaced as a complete assembly. To replace any of the other bulbs you simply open the bonnet, unplug the wiring off the back of the bulb you need to change, and then twist the back of the bulb and it will pop out.

Programming one of Toyota'a new-generation Smart Keys requires you taking your car to the dealer to have it coded to the new key. Specialist computer programs are required as they have to pair your key to your specific car, via the car's computer. This makes the car secure to your particular keys.

Adjusting headlights is a tricky, finnicky process which involves parking the car on dead-level ground 3m away from a perfectly flat surface and making measurements to ensure the cross-beam of your headlights hits just the right spot on the wall. However, you can also take your car back to the dealership and have trained technicians set it up perfectly for you, while you sip on a cup of coffee and read what Jennifer Anniston is up to in the latest trash rag. Adjusting headlights isn't a job for an amateur, given you could blind other motorists or find yourself unable to see if you get it wrong.

Toyota recently launched the 12th-generation Corolla as a hatch model. However, when they unveiled the new-gen model at the Geneva Motor Show earlier in the year they confirmed a sedan variant will follow the hatch sometime in 2019.

There are no firm figures available as at 2018. However, Toyota sold their 40,000,000th Corolla in July 2013 so they will likely be approaching their 50,000,000th Corolla soon!
