The 2023 MG ZS is a budget-friendly compact crossover with a mixed bag of reliability—solid drivetrain but weak points in suspension bushings and transmission mounts that show up earlier than competitors. The electric variant sidesteps most ICE issues but shares the same suspension concerns.
Premature Transmission Mount Failure
Common · medium severityTypical onset: 30,000-60,000 mi
Symptoms: Clunking when shifting from park to drive or reverse, Excessive vibration at idle, Driveline shudder during acceleration
Fix: Replace transmission mount assembly—usually the upper mount goes first. 1.5-2 hours labor. Often find the rear mount also worn once you're under there, so inspect both.
Estimated cost: $250-450
Front Control Arm Bushing Deterioration
Common · medium severityTypical onset: 40,000-70,000 mi
Symptoms: Knocking over bumps at low speed, Steering wander or vague on-center feel, Uneven front tire wear on inner edge
Fix: Upper and lower front control arm bushings wear prematurely—rubber compound doesn't hold up. Replace both sides for alignment stability. 3-4 hours labor including alignment.
Estimated cost: $600-900
Rear Control Arm and Trailing Arm Bushing Failure
Occasional · medium severityTypical onset: 50,000-80,000 mi
Symptoms: Rear-end squeaking or groaning over bumps, Unstable handling in corners, Visible cracking or separation in bushings during inspection
Fix: Rear suspension uses multiple bushings across lower control arms and trailing arms—they fail in clusters. Plan on replacing the full rear bushing kit. 4-5 hours labor plus alignment.
Estimated cost: $700-1,100
ABS Pump/Modulator Failure
Occasional · high severityTypical onset: 60,000-90,000 mi
Symptoms: ABS warning light stays on, Brake pedal feels spongy or pulsing without ABS activation, Loss of traction control and stability control functions
Fix: ABS hydraulic unit develops internal valve failures or motor issues. Requires replacement of entire ABS pump assembly and bleeding system. 2-3 hours labor.
Estimated cost: $1,200-1,800
Front CV Axle Boot Tears and Axle Failure
Occasional · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clicking or popping during turns, Grease visible on inside of wheel, Vibration during acceleration
Fix: CV boots tear early, contaminating joints. By the time you hear clicking, joint is usually toast. Replace both front axles as a pair—saves comeback. 2.5-3 hours labor.
Estimated cost: $500-750
Transmission Oil Cooler Line Leaks (CVT models)
Occasional · medium severityTypical onset: 40,000-70,000 mi
Symptoms: Transmission fluid spots under vehicle, Low transmission fluid warning, Transmission slipping or delayed engagement if fluid level drops
Fix: Cooler line connections to radiator or transmission develop seepage. Replace lines and connections, refill CVT fluid. 1.5-2 hours labor.
Estimated cost: $350-600
Decent budget crossover if you're handy with suspension work or buying new with warranty—avoid high-mileage examples unless suspension has been completely refreshed.
