Had 2 blow outs on a trip to raleigh nc changed first on way their & jack worked fine to replace front passenger tire with my spare, on trip home had a blow out on rear passenger tire since i didn't have another spare tire i had to be picked up 60 miles from home by my wife & went next day with spare tires to change tires and bring car home. upon changing first tire jack worked fine then upon changing 2n tire jack completely stripped the bolt and fell back to the ground tire was still attached or significant damage would likely have occurred this jack appeared to be new condition & never been used. it worked to change 2 tires then completely failed. upon posting my experience on maserati forum several others mentioned the same problem and someone from suggested i post this here. this was a$120,000 car new and never had a jack fail so prematurely. i do not have a jack for my vehicle just the damaged jack any suggestions on how to get a replacement is appreciated also. i have the jack if a photo is needed. *tr
