Honda Rated Highest In Engine Reliability - MG Rover And Audi Rated Worst Warranty Direct’s study of 50,000 live consumer policies shows some interesting facts. Perhaps chief amongst them is that German manufacturers’ engine reliability isn’t exactly what it’s supposed to be - even for premium manufacturers. Audi, for example, was the second worst “offender”, with 1 in 27 owners reporting an engine problem; the only manufacturer who did worse was the, now defunct, MG Rover with 1 in 13 – but then again, the British carmaker never had a reputation for reliability. BMW’s MINI is third, with 1 in 40 vehicles having engine issues, while BMW itself is seventh and VW is ninth. Warranty Direct also studied the cost of engine repairs. A Range Rover Vogue with an engine failure recently led to the insurer’s highest claim ever: £12,998.46 (US $20,642), while a dealer quoted £14,853.60 (US$23,588) to repair a destroyed engine on a Range Rover Sport. On the other side of the spectrum, Honda was the clear winner with only 1 in 344 owners reporting engine troubles, followed by Toyota with 1 in 171, and surprisingly, Mercedes-Benz with 1 in 119.
