| Electrical System problems |
I purchased my vehicle in 2019. Since then, I have had several issues. I've had to replace the coolant reservoir, def heater/pump and twice changed the number 8 injector plug. The warning light came on just after the warranty went out. The code reader read the ambient sensor and no sensor.
Driving to work. Power steering went out and braking system seem to be ineffective. Instrument panel service light came on with the battery indicator displaying "battery charging system" fault.
