Not sure if this helps, but we had a Chevrolet Orlando in 2011. It was only a few months old when it began to develop “gremlins”.
In the end, it had several serious faults – “uncommanded emergency brake assist” being the worst – the car was 2 litre, diesel and with automatic transmission: if you were to lift off the throttle and cover the brake pedal ready to slow down, then brush the brake pedal gently ready to brake – you would get a sudden, full on emergency stop, with brake force that you could not imagine!
This happened three times, twice in town at 30 mph or lower, once on the A1 at motorway speeds! Don’t know how everyone behind managed to avoid us, but flooring the throttle managed to kick-down and override the “uncommanded emergency braking”, but speed had gone down to about 30 – 35 mph by then and all hell was breaking loose.
Anyhow, the point was, the garage insisted twice that there were no fault codes recorded for this or any of the other fault codes that kept flashing up on the dashboard digital display – including the engine management system warning light as the engine stalled at low speed, in gear (automatic!)
The dealership tried to blame my feet for the braking issue and MB supported them – until we managed to take nice, clear pictures of the fault codes, using my wife’s phone.
Within half an hour, we were told we could return the car with no penalty and choose a new car straight away….
