Mazda SUV Range

This sounds like a potentially very dangerous fault. Any car that wanders across the road or doesn’t go where the driver points it is an accident waiting to happen. A serious one, at that. At this point, the first piece of advice is to not drive the vehicle any farther and have it towed to a workshop for it to be inspected.

There’s one other possibility here. And that is that what you’re feeling is the car’s lane-keeping assistance program. This can often feel as though the steering it trying to plot its own course (which it is, in a way) in order to keep you centred in your lane. It only works up to a point, beyond which driver input will overcome it. I wonder if that’s what you mean by 'unsticking' the steering.

However, as far as I can tell, this model Mazda didn’t some with lane-keeping assistance (it has lane-departure warning only) so I think you’re back to square one and a tow-truck. Either way, this should be a warranty issue if there’s anything seriously wrong, so don’t be afraid to try a different dealership.

The sluggish performance and the erratic tachometer needle may not be related at all. That said, they could very well both be symptoms of the same problem. A lot of mechanics, when shown an erratic dashboard gauge, will start by checking for a bad earth point. A poor earth can lead to all sorts of problems, as a healthy flow of electricity is vital to the basic functions of any modern car.

But before you rush out to find an auto electrician, bear in mind that this sounds very much like a problem that would be covered by Mazda’s factory warranty. Provided you have had the car serviced correctly and it hasn’t been submerged in a flood or something equally drastic, the first step is to take it back to Mazda and allow the dealer to tackle the problem.

It’s odd, but some cars just don’t like some brands of phones. Toyota, in particular a few years back, had all sorts of trouble connecting certain phones to its factory Bluetooth system and, even if you could connect, sometimes the reception was so poor that it wasn’t worth the effort.

All the alternatives you’ve listed have their pros and cons, and bear in mind that a Skoda uses VW technology. The main concerns over the years have been failures of, and problems with, dual-cutch transmissions. If the VW tech scares you (or your mechanic) put the Skoda in the same basket. Beyond that, it comes down to your personal driving preferences and what sort of deal you can squeeze out of the dealer.

Don’t forget, either, that we generally upgrade our phones every few years, so if your phone is already an older one, maybe your next mobile will pair with the Mazda perfectly. Or, make it the Mazda dealer’s problem: If they’ll throw in a compatible phone as part of the deal, maybe the CX-3 is for you after all.
