Sent my vehicle (P85+ Model S) to service centre on 28/2. Picked up the vehicle 3 days afterwards. 5 mins after leaving service centre, left front tyre reported to be low on pressure. Pumped it up and problem went away. Upon delivering my vehicle to service centre, i specifically mentioned about the warning light (Smart Air Suspension). They said they would handle it. Guess what, after the tyre pressure was fixed, the warning light came back on again. Wrote several emails to SupportApac and finally got someone returned my call (in fact i called them first). They scheduled my car in for checking on 8th April. Hopefully this time they will get it right. By the way, i demanded for a loan car, and hopefully will have it. Also, during low speed with acceleration pressed, there is vvvvvv noise coming from the back, appears to be coming from the motor. 48000 km (just over 2 years old), and wonder what will happen next. With tax rebate abolished (almost), will you buy another Tesla ?
