Dealer wanted to correctly diagnose the problem first. Diagnosis cost 260$. I asked Dealer to replace both paddles while we were at it. Actual repair cost 50$.

Vehicle will loose acceleration sometimes. Other times, the Electronic Stability Control (ESC) will turn on without human interaction. Scan Tool Error Code C1513. It is alleged that the acceleration and deceleration is caused by a burnt Rear harness Cable - (Replaced).
Acceleration and deceleration and ESC dash light is intermittent. Acceleration and deceleration will occur between 25 and 70 MPH. ESC dash light will turn on after 1 mile in the morning. Due to inertia at 7o MPH you will not feel the loss of engine power, however you will loose the capability to accelerate whilst at the same time the RPM drops to zero. You will notice the change between 25 and 40 MPH.

10 lightbulbs that has had to be replaced! Unbelievable. Never had this many problems on any other car. This time, driver side front headlight was out, and I got pulled over by a cop for the third time and the time that I've owned this car, about five years. This car has a weird if not defective electrical system, bad lightbulbs, or some combination of the above.

A/C pressure was below half of factory specifications. On an earlier trip down South, the A/C was barely working, and at one point, after a ten minute stop after five hours of driving, it blew tiny chunks of ice out of the far right passenger side vent. Since recharge, it's worked fine on another Southern trip, but they put in a dye when they added coolant, so it would be possible in the future to know where a leak was occurring. $200.
