A man flew from Canada to the Mercedes-Benz headquarters in Germany to complain that his $155,000 (£121,403) car was unsafe.

Guifang Huo and her husband Da Tong Yang had bought the car, an S550 model sedan, back in 2017, believing at the time that it was one of the safest vehicles around.

Just a year later, they claimed the car’s steering locked while they were driving along West 41st Avenue in Vancouver.

The motor was taken to Mercedes-Benz Richmond Service Centre the next day, where it was to be repaired, with engineers saying the fault was an ‘internal electrical issue in the power steering rack and pinion gear’.

However, Mrs Huo refused to accept the car and demanded a replacement or a refund.

In 2019, the couple then filed a lawsuit against Mercedes, reportedly claiming to have suffered physically, mentally, and financially from the ordeal.

But that’s not where the story ends.

With little movement coming in the courts, Mr Yang then flew from his home in Richmond to the firm’s offices in Stuttgart in January to complain about their treatment.

Once there, he was given a tour of their offices. Mr Yang later told the Richmond News that he had gone there to get ‘justice’ but instead received an email informing the couple that the company would look into the matter.

The car remains sat in the couple’s garage.

Mrs Huo now claims that the fault with her car caused them ‘considerable mental distress and anxiety, including fear for their family’s safety and the safety of the general public’.

The court documents go on to claim that after fixing the problem with their vehicle, Mercedes-Benz ‘was unable to ensure the plaintiff that the defect causing the failure had been repaired or that the failure would not reoccur’.

The couple also argues that the car was ‘unreliable, unsafe, and does not provide the peace of mind a luxury vehicle should,’ and that the firm ‘breached its warranty of fitness’ as the motor ‘had a potentially fatal defect that caused the failure’.

She is now seeking financial compensation and damages from the manufacturer.

Mercedes-Benz has denied that the issue with the car’s steering affected its brakes, that it led to ‘any personal injury or property damage,’ and that the warranty had been breached.

The firm claims it fixed the fault, returned the car to the owner and explained what had happened, writing to Mrs Huo a couple of months later to explain once again.
