Hi Derek, welcome
The problems you have encountered are obviously bad new for you, but the sort of thing that can (and do) go wrong with any car/make/model.
I have had my RCZ for over 7 years now. It has been serviced by a main dealer every year, I check all levels every couple of days, and it’s been one of the most reliable cars I’ve every had.
I did have a new clutch assembly replaced under extended warranty, but tbh it was only a minor fault - a groaning noise when setting off in 1st, but as I had the warranty I thought I might as well get it sorted.
Reading forums like this can paint a very bad picture about reliability, as most people only come to forums when they have an issue. The vast majority of owners don’t ever come here because they don’t have problems.
I have just bought a brand new Range Rover, it has already been in for a new Balance Shaft as the bearings were seizing, and that on a £50k + car. It’s going in this week for more warranty work, so it shows no matter how new or how much you spend, anything mechanical has the potential to go wrong.
Before the RCZ I had a Renault Megan’s CC which had constant problems with the aircon and had a new compressor.
The main thing with the RCZ as
@Pedro has mentioned is regular maintenance. This is a performance car, and has to be treated as such. But it can still be used as a daily drive, which is amazing given the performance you can get out of it.
Good luck with your car from now on & just enjoy those beautiful lines every time you see it.
Btw we love pictures on here, so let’s see yours
