Our newly bought approved used Honda CR-V has a faulty gearbox - is this covered by the one year warranty?

My partner bought an approved used 2011 Honda CR-V with a one year warranty less than a week ago. On four occasions it's jumped out of first gear when doing less than 10mph for a few hundred yards. Are there any known problems? We're taking it back to the garage for them to check it out. Should she just ask for her money back? It has 46,000 miles on the clock and we've done about 300 of those.
First and second gears are the first to be damaged because they have to take the greatest torque reaction. Back to the dealer to get it fixed on pain of rejection under the Consumer Rights Act 2015. Law here: www.honestjohn.co.uk/faq/consumer-rights/
