From our podcast 8th July 2024 where we discuss vibrations at high speeds, causes and solutions.
4. VIBRATIONS AT HIGH SPEEDS
MG4 X Power Vibe/Hum 65 to 75mph
Wheels not balanced on new car
Dealer refuses to help
PROBLEM: When running at high speeds (typically motorway or at least over 60+ mph), there's a vibration felt through the steering wheel or seat.
CAUSES: There are a number of possible causes of this:
a) Mis-shapen tyres - if the car has stood for a long period of time then part of the tyres may have become permanently deformed, this can happen with shipping/port delays, not just normal ownership.
b) Unbalanced wheels - some owners have reported that their wheels were not proper balanced on delivery. If wheels become unbalanced then it causes a very similar vibration.
c) Vibrations in the driveshafts or suspension components - this can happen in some cases with wear on the suspension components, with higher mileages.
d) Motor vibrations - some dual-motor cars (like the MG4 XPower, Cyberster) have been reported to have some vibration problems, these could be caused by the two motors but we don't currently know if this is the cause.
FIXES:
a) Have your tyres and wheels checked and balance the wheels and replace the tyres as needed for smooth running - this makes a huge difference in many cases.
b) If this isn't the problem, have your dealer inspect your suspension system.
c) If necessary, pursue a warranty claim with MG and have them investigate further.

DISCUSSION POINTS:
- This seems to vary a lot, some people get vibrations and some don't. It is generally rare but more common on specific models (e.g. MG4 XPower).
