2019 Mercedes-Benz GLC 2.0L Petrol · AD68 FOU

The defining mechanical event in this GLC's record is a single major failure recorded on 17 December 2025, where the nearside front outer constant velocity joint boot on the drive shaft was found to be split to the extent that it could no longer prevent the ingress of dirt. The vehicle subsequently passed an MOT the following day, 18 December 2025, with no defects recorded, indicating the boot was likely replaced or repaired in the intervening period. Prior to this isolated failure, the car had demonstrated a clean roadworthiness profile across four consecutive annual tests from January 2022 through January 2025, with no advisories or failures of note. While the record cannot be described as universally clean due to the late-2025 CV boot failure, the overall trend shows a vehicle that has otherwise passed every test without recorded defects, with one isolated driveline sealing issue being the only blemish. With 27,161 miles recorded over approximately seven years, this GLC has been driven at an average of roughly 3,880 miles annually, which is notably low for a vehicle of this age. The consistent year-on-year test entries with no significant gaps suggest the car has remained in regular use rather than being laid up for extended periods, although the low annual mileage does mean that some components which benefit from frequent operation, such as the diesel particulate filter or battery, may have seen less thermal cycling and charging activity than typical examples. The mileage progression between tests appears broadly consistent with gradual accumulation rather than any abrupt jumps that would suggest heavy use between specific dates. Given the specific failure of the nearside front outer CV boot, a prospective buyer should pay close attention to the driveline on a test drive. Listen for any clicking, knocking, or rhythmic slapping noises from the front of the vehicle, particularly when turning at low speed or when load is applied, as a torn boot that has allowed prolonged contamination can lead to premature wear of the CV joint itself. Inspect the inner and outer boots on both sides for any fresh grease residue, splits, or perished rubber, as these are common failure points on Mercedes-Benz drivelines and a recurrence would indicate either a poor quality replacement or an underlying issue. Beyond the recorded failure, the absence of any suspension, brake, or corrosion advisories across multiple tests is a positive indicator for a vehicle of this vintage, though the low mileage means physical inspection remains important. On a test drive, listen for any clonks or rattles from the front suspension over uneven surfaces, which could indicate worn anti-roll bar drop links, control arm bushes, or top mounts that have perished from underuse rather than wear. Check for any pulling under braking or vibration through the steering wheel, as seized caliper slide pins or slightly corroded brake discs can develop on low-mileage vehicles that have spent time stationary. Finally, examine the underside of the vehicle, paying particular attention to the subframe mounting points, brake pipes, and exhaust hangers for any surface corrosion that may have developed despite the limited mileage.
