SAFTE CONCERNS: 1. Vehicle has sever severe pulsing/shaking/jerking behavior in motion. So far I have encountered this problem when the vehicle was under 20 mph; 2. Vehicle lightly pulsing/vibrating when braking and does not stop smoothly; 3. Stepping on the gas pedal for 100% acceleration, the vehicle only went up to 30~40% power. BACKGROUND: I purchased this vehicle (with 25miles shown) on 4/21 evening around 9 pm PDT. Saturday 4/22 evening, the first time I took the car out for a drive, I experienced the concern 1 and 2 as stated above then I took it back to the dealership on 4/23 morning. I have recorded videos when vehicle was shaking. I will follow up with video attachments in email. The dealership diagnosed the car and did verify the strange behavior, but said all problems were fixed by the real axel steering software update from 4/24 to 4/25. Please find attached the service report. I then drove the car back with 91 miles shown on the vehicle 4/25 evening. However, 4/25 night, when the vehicle was reaching around 110 mile total mileage, I encountered the same issues again, along with a new one as described in concern 3 above. Through out the whole process, the vehicle was never over 40 mph, so no one got hurt or no accidents happened while the vehicle lost control. However, the issue was random and happened in my drive way, at traffic lights and as vehicle is turning on the roads, these strange behavior could not only risk passengers in the car but also put surrounding vehicles and traffic into risks. The vehicle only throw two error messages ONCE on 4/23 morning: 1) rare steering malfunction 2)auto brake system malfunction.
