I have a 7 year old RCZ I was driving last week and my car made a thudding sound and cut out.Turns out my Timing chain had broken.I had no warning no noise coming from the engine no warning light.My car was towed to the garage .The car is 7 years old but has only done 25.600 miles It is only used 8 months of the year as I go abroad.The garage is replacing the timing chain but they are still not sure if more damage has been done to the engine.It is going to cost between 1500 to 2000 pounds .Has anyone else had a problem with the RCZ ?
