Right rear sealed wheel bearing failed and was just replaced at 50,564 miles at a cost of $1,142,82, parts, tax, and labor. I have seen correspondence from approximately 12 other owners of this model vehicle (12,500 imported to the USA by Chevrolet over 4 years), who have all experienced similar failure of front and/or rear bearings at 40-50k miles. These bearings reside in the knuckle assembly of the suspension system. Failure of these bearings can cause fires, accidents, and/or other more catastrophic damage. Fortunately, I noticed the noise of the failing bearing before any incident occurred. Sealed bearings, which cannot be serviced as regular "open" bearings are at intervals, should not fail so soon. Open bearings can easily last over 100k miles with regular service. It is unreasonable for owners to expect $4,000+ in seal replacement expense at such low mileage. Chevrolet should pay for these repairs and provide a better bearing unit.
