Hello Mazda forum. Last evening my wife and I bought our first Mazda vehicle. We got a Machine Grey Metallic AWD CX-5 Grand Touring with the GT Premium package and 2.5L engine. My wife was in need of a new vehicle and we tested a lot of different brands and models. The CX-5 ended up at the top of her list. Anyway, we took this particular CX-5 for a short test drive and we made it short because we had already tested and drive several other Mazda CX's at a different dealership and felt we were familiar enough with them. On our way home my wife was driving and we both noticed the car had a shake to it, felt like the rear tires were not balanced. Nothing dangerous but definitely annoying and we could feel it more through the seats, wasn't to terribly bad through the steering wheel. I noticed the shake was present at any speed from 20MPH to 70MPH. I'm not a mechanic but in my experience an out of balance tire usually caused a little shake at certain speeds. I then thought it may be flat spots on the tire from the car sitting so long during shipment. Once home I did a google search and found that the most common cause of this shake is out of round Toyo tires. Of course other causes were bad wheels, bent or broken drive shaft, bad brakes and alignment issues. What I also noticed when reading the google search results is that many people commented it was a common problem with Mazdas and highly recommended to not swap wheels with another Mazda vehicle to see if the shake changes.

Needless to say we are not too happy about this issue but we're not getting too excited about it yet. I'm going to call our salesperson on Monday and report the shake and see when we can take it back to be checked. My wife and I do not have a very good history with any dealership service department and after a few bad experiences, we're pretty much skeptical of any service department's willingness and ability to correct issues. I'm wondering is this really a common Mazda problem? If it's a common problem I'd think the service department should know how to resolve it fairly quickly. I searched this forum and couldn't find too much about shaking. Given the dealership is over an hour away, it's very inconvenient to go there and I'm afraid this is going to take many trips to the service department to fix. If this problem makes them scratch their heads, what should I insist they do? Is it unreasonable to expect them to mount four new but different brand tires and see if that is the cure? Do you think this should be covered by the warranty or because tires are a wear item, it's not? Personally, I think they should cover any and all costs to fix it. This should not be happening with a brand new vehicle with less than 100 miles on it.
