Where to start explaining this. Part 1: I bought my Mazda 3 165 Sport with 11k on the clock back in January from this dealership (65 plate) and had to return the car at least 5 or 6 times to sort out various problems they didn't bother to sort out when I initially picked up the car (broken Bose speaker, front wheel arch linings loose to mention a couple of things). Also, the car has never driven properly as it should do, I suspect there's a throttle problem with it but they said there wasn't anything they could find when I raised the issue with them at the time of purchase (probably a fob off). I've since test driven another 165 Sport on similar age/mileage at another dealership just to check i'm not imagining there is a problem with my car and that pretty much confirmed that mine does have a problem.
Part 2: My partner owns a Mazda 3 2.2d Sport bought from same dealership brand new in 2017. The car developed a sticking wing mirror problem earlier this year which we reported to the dealership. When we took the car in for the fix, they instead did some issues that the car was on recall for (windscreen wiper motor/engine management software update) but not the issue we'd brought it in for, just totally randomly. This meant yet another re-visit for the wing mirror issue. Now the most recent issue is that the DMF has begun to fail after 17k (makes a grinding noise on gear change) but they are playing hardball replacing it on the warranty. The dealership asked my partner to drop the car off this week for 3 days advising her they were going to fix it. After having the car 3 days they have now decided they won't fix it until we provide evidence recorded on a mobile phone that the car is making a noise when changing gear. Their technicians are saying they have heard the noise themselves while testing the car but Mazda UK don't believe them so won't foot the bill of repair until there's a recording made. Never heard such bollocks in all my days.
The dealership overall are hopeless. Never call you back, get jobs mixed up you've asked them to do and generally string you along. This has really put me off Mazda cars after owning them over 20 years. It's staggering how a dealership can be so utterly hopeless continually.
