1300 miles - CD player stops working. Replaced under warranty.
2500 miles - Rattle from underneath car combined with excessive (although not unpleasant) exhaust noise. Dealer diagnoses catalytic converter (over the phone, worryingly) and replaces it under warranty. Problem solved.
7000 miles - Repeat of catalyst problem. Dealer service manager lets on that it's happened to a few 190's they look after and thinks it's to do with the aggressive valve timing and lift over 6,000 RPM allowing unburnt fuel into the exhaust on the overrun. Great! Again, warranty pays up.
8000 miles - Notice the front tyres are worn unevenly. Dealer checks suspension geometry and finds several settings are massively out of kilter. Adjusts to spec. Promises to take up the case of a replacing a knackered set of P Zeros with Toyota.
9000 miles - First service and I ask for what sounds like a gearbox whine to be looked at, combined with some play in the gearchange. Change quality sorted by dealer, but noise is still there. Toyota won't budge on the tyres due to "excessive pre-damage wear".
14000 miles - Total gearbox failure on the M4. Leave the motorway slip and it refuses to shift out of 6th. Car is towed in. Gearbox dismantled and a retaining clip inside the gearbox is found to be missing. Toyota want to repair the 'box. I demand a replacement. After much arguing, a new style, stronger "T Sport" box is fitted under warranty.
16000 miles - Third catalyst goes pop. New firmware downloaded to ECU which should fix the problem. Car feels livelier "off cam" and pulls harder up top.
17000 miles - Vibration from steering at motorway speeds. Notice a front wheel rim is bent. Car has never been kerbed - no other damage to wheel. Smaller dink noticed on opposite side rear wheel. Dealer says the wheels are too soft and have been modified on new models. All four wheels replaced with new type under warranty (but not the tyres!)
23000 miles - Brake pedal goes to floor at a junction and then recovers. Dealer discovers a bulging hose and an iffy master cylinder. Replaced under warranty.
29000 miles - Engine management light comes on. Car runs normally, but starts drinking fuel. Dealer's diagnostic rig does not show a fault. I take a courtesy car until it is fixed. 6 weeks later, another "firmware upgrade" fixes the fault.
33000 miles - New gearbox has started whining just like the last one, and the engine is starting to sound rough, especially on cold. Lots of tappet noise and a hesitation when throttle is initially applied. Both are currently under investigation.
