My experience with American vehicles tells me that they will begin need major repairs at or about 70,000 miles. My Jeep Cherokee is no different. I have 69,500 miles and will pickup my vehicle and its repair tab of about $1000 tomorrow. No repairs were due to negligence -- they were due to normal wear and tear (power steering, power window and front end). My last American vehicle was from the 1980's and my next probably won't be until the 2080's! Additionally, electrical features stink. I've have repetitive problems with a speaker wire crimping in the driver's side door and a repetitive yet intermittent problem with passenger side power window.
None -- very disappointed.
Improve design to prevent some problems mentioned above. Head room needs to be increased. I am 5'10' and my head touches the interior roof. Also, engine noise and passenger compartment soundproofing needs to be improved.
