2023 Ford Mustang Mach-E EXT Range RWD Electric · LF23 JCG

The 2023 Ford Mustang Mach-E Extended Range RWD presents a mixed roadworthiness profile defined primarily by a brief period of unreliability followed by a successful final inspection. The vehicle's most recent MOT on 2026-06-11 passed with no defects recorded, yet earlier in the same calendar month it had failed due to non-functional nearside and offside front windshield washer systems. This pattern of intermittent failure—one test failure immediately preceding a passing result—creates an impression of inconsistent mechanical health rather than a consistently sound platform. While the latest test clears the vehicle for sale, the prior failure warrants attention before committing to purchase, particularly regarding the windshield washer circuitry and associated plumbing. The recorded mileage of 37,645 miles across a three-year ownership period translates to an average annual accumulation of approximately 12,548 miles, a figure substantially higher than typical for vehicles of this age and body style. Such rapid mileage progression places additional strain on the powertrain, suspension, and drivetrain components compared to a standard three-year-old vehicle, potentially accelerating wear on seals, bearings, and rubber mounts. The high usage rate also amplifies the likelihood that minor issues identified during the failed MOT may have progressed undetected, especially given the limited time elapsed between the two MOT examinations. A vehicle accumulating nearly 13,000 miles per year will require vigilance regarding fluid levels, tire tread depth, and structural integrity. Focusing on the specific advisory item from the MOT history, the front windshield washer system requires particular scrutiny on test drives. Listen for any audible clicking or grinding when operating the washer switches, which can indicate worn linkages or corroded pivot points. During driving, observe the flow of water from the washer nozzles; persistent pooling or stuttering spray patterns suggest internal seal deterioration within the washer pump assembly. Additionally, check for signs of moisture seepage around the washer reservoir housing, as prolonged exposure combined with high mileage can accelerate corrosion even in otherwise protected areas. Given the reported failure, verifying that the entire electrical system functions correctly under load—particularly the washer motor and its wiring—is essential to confirm the root cause of the original failure. Beyond the windshield washer issue, the buyer should still conduct a thorough practical inspection given the elevated mileage. The high annual mileage accelerates normal wear on the front suspension bushings and control arm pivots, so checking for excessive play, clunking noises over bumps, or abnormal handling during cornering is advisable. Although the MOT did not flag brake, transmission, or chassis concerns, the combination of heavy use and a recent washer failure means the vehicle may have accumulated minor issues elsewhere that did not reach the threshold for MOT failure. Ensuring the cooling system is functioning properly, as EVs place unique thermal demands on charge management units, and confirming that all electronic displays function normally upon startup would provide a complete picture of the vehicle's readiness for road use.
