 My car was flawless for the first 21,000 miles (2 years). The problem was initially diagnosed as "collapsed engine lifters" but after this repair failed to correct the issue a new engine "short block" was installed.  After another 1,750 miles the "new" engine short block proved to be "defective". During the 5 weeks the dealership had the car to install the 2nd short block we gave up and bought a Nissan. Very disappointing.
