problem #6

  • 79,800 miles


I was driving down the highway at 70mph (posted speed limit) when the RPM gauge dropped to 0 and the car lost power. I was able to ease my way onto the shoulder but with no power breaks I had to mash down the break petal finally coming to a stop. The vehicle was towed back into town and am still waiting to find out the cause of this issue. The car has less than 80,000 miles on it! I have dealt with the ignition switch recall, the timing chain has been replaced twice already, the headlights and break lights have to be changed every 3 months just about, and now this!

Timing chain is off time after so many miles the vehicle was stationary and still is stationary due to a rattle noise and the engine not wanting to run properly.

When pep boys first removed the passenger rear engine cradle bolt back in March, the factory nut broke off from being welded to the car body. When a local mechanic recently removed the bolt for related service, he showed it to me. The threads on the middle of the bolt shaft were all seemingly chewed up. The local mechanics best guess was that the air conditioner condenser drains on to that area, which originally weakened the factory welded nut, and causing corrosion on the engine cradle bolt. The bolt won't last long, and I have ordered a replacement bolt, at my expense, to replace the prematurely 'worn' original bolt. Unfortunately, not much can be done to restore having a factory welded nut to receive said bolt. Had I not commissioned the additional work, I may have had a serious accident in the future, unaware of the bolt corroding away!

problem #2

While driving on icy roads, the car began to slide and spin out of control. As I attempted to correct the motion of the car, the engine switched off. And because the engine had switched off, it became impossible to turn the steering wheel. The car spun around at least 3 complete rotations (of 360 degrees) before sliding to a stop on the side of the road. The gear shift was still in drive, and could not immediately be changed to park. But naturally, the car had to be restarted, which it finally did after much effort. And the car could be put into park after the engine had restarted.

I was just driving home an on the freeway the car just stopped, I was lucky that I could just coast in to a safe area. After awhile I turned it on an it started up.. the same thing happened today 2/26/14 I stopped at the post office and it would not turn on I waited about ten minutes and it started. It seems to be the ignition.
