It has some issues, first the windsheld wiper, when the car is started (engine running) the intermediate wiper speed dose not work but!!! When the key position is in 2nd it works. Second is the radio, the car is equipted with a phone, so when ever he turn on the wiper, hit the brakes, change the gear shifter,(when the radio is on) the radio shows PHONE on the display screen and the radio is muted (no sound when the word phone is present), and when he hit the brakes hard the radio works for a few seconds and then goes back to PHONE... It also slips in to 3rd gear, i have to let off the gas pedel in order to shift into 3rd gear...

Overall mechincaly running SUPERB, it very smooth, no misfires, no vibration and it has LOTS OF POWER after all the car that car have been sitting for 3 1/2 months and it fires up on one crank...

Possibly the alternator is OVER charging..try connecting a volt meter & see when the problem is there IF the voltage is correct OR too high.
