CX‑90 Safety Issues and Corporate & Dealer Negligence

Hey everyone,

I’m posting in the CX‑90 forum because I’m trying to connect with other Mazda CX‑90 owners who have had serious issues not just with their dealer, but with Mazda Canada corporate as well.

I bought my Mazda CX‑90 brand new, paid in full, and almost immediately started experiencing two major problems:



1️⃣ CX‑90 Acceleration Lag
  • Severe acceleration delay when merging or entering highways — sometimes taking several seconds to respond, which is dangerous when trying to merge into fast traffic. This is a nightmare for my wife, with our two kids in the backseat, 5-6 second delays in throttle response is not uncommon.
  • This acceleration lag is not covered by any Technical Service Bulletin (TSB), but Mazda has been unable or unwilling to fix it after 7+ months. They just want us to keep trying to diagnose it. They have no clue, and both the dealer and Mazda Canada field techs can't figure it out.


2️⃣ CX‑90 Headlight Water Intrusion
  • Rainwater leaks inside the headlight, which is covered under an official Mazda TSB.
  • Even after acknowledging the issue in January, Century Mazda in Halifax did not order the TSB repair part until March, and only after I followed up multiple times. Then they just ghosted us, and Mazda Canada is OK with that. They have shared that its OK for dealers to not respond to customers if they choose, even on serious safety issues.


Century Mazda / Century Auto Group Issues
  • While my vehicle was at Century Mazda for service, it was damaged in an accident on their lot, driven by their employee.
  • The dealership initially misled me about what happened. Only after I pushed for proof did they admit an employee with a known history of incidents caused the damage. We had to trace the damage back to them, even though they knew it happened, they didn't tell us.
  • After admitting fault, failing to repair the issue, and delaying the TSB part order for months, Century Mazda cut off all direct communication.
  • Mazda Canada told me dealers are “allowed” to refuse to speak to customers — even when serious safety issues are unresolved.


Mazda Canada’s Equal Incompetence
Mazda Canada has tried to distance itself from Century Mazda, but both have been equally incompetent, one through negligence, the other through deliberate inaction.

Despite escalating to Amy and David at Mazda Canada (who I’m told have been briefed but will not speak directly to customers), there has been no resolution.



7 Months, No Fix — Mazda’s “Solution”
It’s now been over seven months since I reported the CX‑90 acceleration lag and headlight water intrusion.
  • Calls and messages have gone unanswered for weeks.
  • Mazda Canada’s proposed fix? Trade in the CX‑90 and let another family inherit these safety problems. Yes seriously - they want, and are OK with transferring the issue to another customer.


Why I’m Posting Here
Given the delays, the documented knowledge of these defects, and the admitted service damage, I believe this may be negligence and a breach of Mazda’s duty of care, as well as their corporate ethics commitments.

I’ve fully documented the CX‑90 acceleration lag, CX‑90 headlight water leak, and Century Mazda dealer damage here:

If you’re a Mazda CX‑90 owner experiencing similar problems, please share your experience here. I’m hoping to connect with others who have managed to get Mazda to resolve these issues.

Thanks

It is unfortunate, but car dealerships do have the right to refuse service with or engage with customers if that's what they decide. Sorry you're having such a terrible time with that dealer, they sound awful. You should indeed be getting better support from your dealer.

I found this reddit post about Century Mazda. I also found that there is another Mazda dealership you can try to get assistance from, Steele Mazda. It's about 20 mins away from Century. Maybe you'll have better luck with them?

Thanks! I am following the Mazda escalation procedure. Mazda Canada has been involved since February, so its not really just a dealer issue anymore. Mazda Canada would love nothing more than to reset the process and further delay it, but we have met the requirements already and had their field service Managers attempt to fix without success.
