After replaced steering rack and engine mounting, proton. X70 start to vibrate. Proton said it’s due to tyre. 22 months 17k mileage is normal for such tyre wear or due to unresolved issue of the car since first day of purchase?
Since last year, my Proton X70 (2025 MC2) has had an unresolved engine mounting and steering rack problem. After close to a year of back-and-forth with the service centre, I finally secured a Tribunal award for Consumer Claims order directing Proton to repair my car within 14 days.
Proton pushed the repair back to July.
When it was finally done:
🔧 Steering rack replaced — TWICE. The knocking sound is now more frequent than before.
🔧 Engine mounting replaced — now the WHOLE car vibrates, seat and floor included. Before this repair, it was only a mild vibration felt on the dashboard.
Yesterday, after a long wait, I finally sat down with Proton HQ’s technical team.
Their verdict: it’s my tyres.
I’ve been told to replace them immediately, or they won’t even able to proceed with further inspection.
The vibration that only appeared right after they replaced my steering rack and engine mounting is eventually caused by my tyres. My idling vibration on the engine and car seat as well as cabin is due to vibration transfer from ground to my tyres.
They said my tyre wear because I didn’t take care of my car tyres.
I check my tyre pressure every 2–3 weeks, keep it around 220kPa-230kPa as it fluctuate based on temperature. I wash my car at a carwash that is 3 minutes from home.

Would due to the unresolved steering rack and engine mounting issue cause the premature wear?
I’ll take their advise to change two tyres that is premature wear. Just wanted to know what the reason that cause that and how come tyre would cause immediate difference vibration right after the steering rack and engine mount replacement. The steering rack took tok sound also become more often and obvious..
