My 53 plate Grand Espace 2.2 DCi has gone over 101,000 so I count every day as a bonus...
All the usual problems along the way at serious expense...
Major clutch issues (warranty year 1 - 20 days off road)
Electronic handbrake issues (warranty year 1)
valve, replaced at 50K, cleaned at every subsequent service...
Cracked rocker cover at about 55K
Disappearing electronic dashboard
Leaking injectors, 2 replaced at 98k
plus a myriad of smaller issues
Every single (non Renault Warranty) problem ever experienced was disallowed by the small print in my Warranty Direct
policy apart from replacement of a faulty air-flow meter. £2ks worth of premiums over 3 years returned £140 in payouts. If you own a Renault, this warranty is definitely not for you! (Actually, I suspect it's not really for anyone despite Honest John's hearty endorsements!)
Bizarrely, I still love it. There just isn't another MPV that is as comfortable and enjoyable to drive.
