Re: Little concerned to buy a 2005 XC90 2.5L FWD with 75K miles. See ... (1sttimevolvo)
Most folks think this is the most reliable configuration for the XC90. No potential angle gear issues from the AWD. Likely the best mileage as well. Pull the oil cap on any you look at and look to see evidence of how well the oil was changed, and check for sludge. Also, find the yellow handled dipstick for the trans and check to see if the fluid is dark or smells burnt. Most any of the XC have issues with bearings at unpredictable intervals, and many have issues with rubber parts in the suspension. Due to the weight, many go through tires and brakes fairly regularly.
But putting these potential concerns aside this is a very enjoyable vehicle, has great utility and packaging, is comfortable, and is a stellar road vehicle. Built like a bank vault, quiet, and some of the best seats in the industry.
I have a friend who regularly buys XC90's in this configuration with many happy customers. But he won't touch a T6. Most of the reliability issues associated with the XC90 are with the T6, and this is confirmed by searches here, and by specific notes to avoid the T6 by Consumer Reports.
