After some more problems (stopping in traffic, impossible to start again, slight rattles at idle) went to the dealer. The following parts were changed:
- Electronic Gear Selector
- Crankshaft Position Sensor
- all 12 sparkplugs (there were barely 11,000kms on them, but dealer insisted all should be changed)
- Cylinder #2 ignition coil;
- 4 spark plug wires
- engine hood release cable and handle.
Total costs (including labor and taxes): $2035
Sparkplugs were clearly overpriced, most possibly all parts were much more expensive than counterparts bought from a shop
Dealer offered 2 year warranty for the repair
