The other morning, when icy, I started my 2014 plate tourer but could not put it into reverse gear. I could move the gear stick forward and back but not side to side. I tried the car a couple of days later while speaking to a after sales people (only had the car 3 weeks) and had no issue getting any gears. On the day the car was due to be collected (it was frosty all day with low temperatures) I tried the car again and had the same problem selecting gears. Since then the mechanic has ran a diagnostic which has shown no faults and taken it for a test drive with no problems. I'm not happy taking the car back and they can't find any problem. Can anyone offer any advice on what the problem could be please?
