Hi everyone,
I'm new here, as well as a new Lexus owner (2007 RX400h) I've noticed that when I'm sitting in my car while it's on (lunchtime at work, I sometimes sit in my car with the engine on to warm up and listen to the radio), the car seems to jerk. It feels like a slight backward jerk and happens once or twice within the first 8 minutes of the car being on. It had a full service with Lexus and MOT passed the week I bought it (almost 3 weeks ago) and has LOW mileage (36k). Timing belt, water pump etc all checked and changed if needed.
Is this jerking normal and something anyone's experienced before?
Thank you in advance
