“I purchased my car used with aprox 45,000. Miles on the odometer, I test drove it & it ran & handled perfect. As soon as I took the car home I brought it to my mechanic to check it out, I got the oil & filters changed & car inspection, all was good. I owned the car for 3 years & maintained it regularly. One morning I started it up & it started popping & jumping (the day before it had run perfectly) & my check engine light was flashing. At this time there was approx 65,000. Miles on the odometer, there was less than 1000 miles since my last oil change. …”

“9/25/2012-I am having some severe issues with the brakes on the M37. Yesterday I just avoided an accident with the back end of a ups truck as the car would not stop. This is the third time that something like this has happened with the brakes. Each time it has been while traveling above 50 MPH and trying to stop quickly. The reaction of the car is similar to that of an anti-lock brake system when you are on wet or icy roads. However, the roads have been perfectly dry and the sun is shining. …”

“Have owned the car slightly over a year. Since the beginning the transmission has shifted erratically, is in 4th gear at 25 MPH. When stepping on gas the car hesitates while trying to pick a gear. There is no power at low speeds because the car is in too high a gear. At higher speeds if you touch the brakes the car drops two or three gears causing the car to shake violently from the downshift. The engine knocks constantly at low speeds due to the gearing even though premium fuel is required. Dealer has tried to repair and applied software patch that took almost a year to receive but no help. …”
