Since I purchased in 2009, engine kills anytime, mostly when gas pedal not pressed. Pulling out of parking lots, sitting at red lights, or letting off gas on interstate, engine just kills. Sometimes feels like a jolt. I have to put the shift in neutral and restart the engine. Records of all visits for the problem at dealership. Never could solve problem, but too unsafe to donate to my grandson. If something were to happen to him because of a defect that was never found, I don't know what I'd do. Cannot check transmission fluid level. Sealed. I do have some fluid stains on my driveway. For years I've reported to the dealership and specified the concern for safety but to no avail. It kills anytime. May not die for a week, or tomorrow, or even a month. No particular pattern. Feels like a transmission problem. If I'm sitting in a parking lot with motor running, sometimes it just kills. It's the shifting to neutral while driving on highways and streets to restart while moving I'm worried about. I've had several mechanics claim they fixed it but to no avail. Please give me some direction. All the shops I've gone to are reputable businesses. One mechanic said the electronic brain (computer box) might be causing and said to send it to Mercury for recalculation. I don't know about that. Most of the read outs are epa related.

At 28000 miles the transmission started shifting erratic, the dealer reprogrammed the ECM and covered up the problem until the warrant ended and the battery failed at which time the car reverted back to default and continued to buck and jerk until the car reached highway speed. This continued until the transmission finally failed during operation on the highway on 3/5/20. The ABS module just failed during low speed operation for no apparent reason. Also the car indicated that there is an electrical problem even though all electrical components are in good operational condition. This error comes and goes constantly at any given time.

Takata recall while my vehicle is in motion, & when I stop at a stop light, it's suddenly shuts off. This has happened several times while on the highway at highway speeds, & on city streets at normal speeds. It has proven dangerous several times. When I put the vehicle in reverse, the vehicle jerks very hard. Also when I drive for more than 6 to 7 miles at highway speeds, a tire pressure sensor comes on.
