Rear Suspension of CX60 Damping inadequate to regulate rebound

[coolguy]

Yesterday, while navigating a bend at a furious pace, my Mazda CX60's rear wheels almost departed off the roadway, resulting in a brief and alarming moment of potential loss of control. In my vicinity, several road portions exhibit significant depressions and abrupt elevations resulting from subsidence and inadequate maintenance. While driving my Mazda at speeds below the limit on some routes, the rear wheels often almost lose contact with the surface, causing items in the trunk to go airborne. The front wheels stay on the pavement. my occurrence is unique to my automobile, since it has not happened in any other vehicle I own or have previously had. It is rather unsettling and quite frightening. My judgement is that the rear dampers lack sufficient stiffness, and/or the spring rates are excessive for the vehicle's weight. The outcome is a vehicle that performs inferiorly to a 1960 transit van, which is regrettable considering Mazda's attempt to compete with the BMW X3. My previous X3 never exhibited this behaviour. Has anybody replaced the rear dampers on their CX-60, and what kind of dampers have you installed? The standard options are clearly inadequate for the vehicle's weight, considering the batteries and other components. This is a prevalent issue associated with the recent influx of heavier vehicles resulting from batteries. This was a prevalent grievance among several individuals over the previous CX-60 models, and I was under the impression that Mazda rectified this issue prior to my acquisition of the new vehicle in June 2024. Mazda CX-60 PHEV with 25,000 kilometres driven.

The CX-60 suspension, an enduring advantage...

I had a really intriguing encounter. In 2023, I purchased KONI shock absorbers. One of the rear ones leaked after 150 km, prompting its replacement. For a duration of two years, until July 2025, I believed the car's general handling had enhanced. The front ceased to dive when braking and exhibited reduced vulnerability to crosswinds. However, the rear continued to oscillate, prompting my need for firmer springs. Concurrently, the vehicle began to vibrate in the back when braking, prompting me to take it to the service centre. They examined all aspects but discovered nothing. My last recourse was to examine the shock absorbers. The front was pristine, but the back was questionable. Utterly destroyed, emitting gas leaks. I used a vehicle with defective shock absorbers for two years, mistakenly believing the issue was with the spring. I was fortunate to have two months remaining on my warranty. I have already driven 5,000 km on the new ones, and that is all I can convey. The back of the automobile exhibits no bounce whatsoever. I am composing this message in response to several remarks, including those underneath KONI's YouTube video, where consumers assert that the situation has worse compared to prior conditions. I assume they possess compromised shock absorbers from an initial manufacturing batch. I am now fully content; I too experienced what you described on a rough highway—trucks began to overtake me. Today is ideal.

Could you kindly explain how you diagnosed the issue? In Poland, there exists equipment to assess damping effectiveness in vehicles; however, similar technology is absent in the UK. My rear Koni shocks seem to be excessively bouncy lately, causing my vehicle to rebound over speed bumps once again, prompting my curiosity. Thank you

Regarding the machine in question.

I am quite pleased to have removed my Koni shocks, which were utterly unsuitable for UK conditions.

The southeastern issue persists indefinitely. I conducted a thorough search; however, none of the postings indicated that anybody considered the automobile to be really hazardous and erratic, like to the Morris Marina of the 1970s. In my view, without varied dampers and gentler springs, my automobile is perhaps more hazardous than the unfortunate old Marina. Despite thousands of complaints, it seems that Mazda exhibits a lack of concern for the rectification of the vehicle in the recall, a situation that is somewhat commonplace in Britain.

Mazda and the automotive media said that they had resolved the suspension issue in the 2023 specifications, coupled with the problems related to the wireless charging, which first motivated the purchase. I cannot see how Mazda deems it acceptable to sell vehicles with several recognised and basic defects.


It has become almost inconsequential for me; this weekend, I acquired another BMW to augment my collection. The dealers, comparable to the Mazda dealer network, will greatly irritate me; but, the BMW will certainly not endanger my life or my family's in a severe loss of control at relatively low speeds. It is noteworthy for others in this discussion that the trade-in value was much lower than the purchase price of the vehicle. It is possible that purchasers of pre-owned Mazdas possess knowledge that we lack. I am still awaiting developments on my CX60 and will continue to use it as a backup vehicle at a reduced speed.

Upon further examination, it has been often likened to comparable experiences; I believe I have described it as akin to being towed down a road in a metal tub equipped with Halfords lowering springs on many occasions. The Pogo effect almost resulted in a crash in 2023; the Konis mitigated this issue but significantly diminished comfort to an intolerable level for everyday usage. I now have the 2024 rear dampers installed, and while they are an improvement over the originals, they remain suboptimal; nonetheless, they are less problematic in comparison to the significant gearbox troubles I am experiencing.

Mazda UK is utterly reprehensible. Arguably the most inadequate customer service of any automotive company with whom I have interacted.

Await the moment when you begin to see the irregular gearbox and "surges" in velocity. I have been addressing that "feature" for two years, and it remains unresolved; I lack confidence in their ability to rectify it. Extremely disappointing from Mazda; I will not make another purchase.

[coolguy]

Rest assured, the remaining issues are fully accounted for. Erratic gearbox surges, driving aids endangering cyclists and oncoming traffic, excessive tire wear and poor navigation performance. The majority do not lead to the demise of my family. Overall, this vehicle is subpar and incurs significant monthly expenses due to depreciation, since no rational buyer would purchase it until Mazda addresses all existing flaws.
