“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.”
NHTSA complaint #10566107, filed 2014-02, 45,000 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!”
NHTSA complaint #10884198, filed 2016-07, 79,800 miles“At the end of september 2013 I noticed a disturbing noise when I started my car. It was a loud rattling sound that lasted about 3 seconds when cranking my car. To my surprise the timing chain had snapped in half. On october 20-21, 2013, the timing chain set was removed and replaced by a trusted mechanic who informed me that I was lucky the engine had not been damaged. My complaint in question is why at only 54,540 miles did the timing chain snap in half? My next question is have there been any other complaints made by other owners or manufacturers of this model relating to this issue? …”
NHTSA complaint #10574568, filed 2014-03, 54,540 miles“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. …”
NHTSA complaint #10651763, filed 2014-11, 102,000 miles“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.”
