Hi Stephen
I am a mechanical Engineer, time served on Diesel engines, I own the latest Honda CRV 2.2 and can say the vehicle as very little issues that concern me. Other than a very slight squeeck from the clutch pedal when depressed all is fine.
The CRV maynot have an high BHP at 140 but impressive low rpm torque that allows good towing performance on my 1300kg Coachman.
Not sure how safe any vehicle would be at 100% but the Honda does have trailer stability assist as standard and most people on this forum forget to mention this.
All I can say is most vehicles have some problems/issues but with Honda you are just nit picking, the Renault engined Nissans including X trails have major issues with Turbo failures and a host of problems reported on some forums and known in the trade.
Anything with a Honda badge is usually the best you can get for your money, from Lawn mowers, portable generaters, motor bikes to cars, wish they made a caravans.
Best Regards
Alan
