Suspicious Maintenance Suggests a Cause for Red Flags Suspicious Maintenance Suggestions a Cause for Red Flags (Auto Weekly‪)‬

Dear Tom and Ray: Today I took my 2005 Prius in for its 55,000-mile routine service. I have been basically faithful in getting service done on schedule since getting it new in May of 2005. In addition to the routine maintenance items, they suggested: (1) MAF (Mass Air Flow?) Sensor, $52; (2) Service Throttle Body, $89.95; (3) Vent Service, $70; (4) Drive Belt Noise, $135 (Replace Belt); (5) Adjust Parking Brake, $89.95; (6) Nitrogen Tire Service, $20; (7) Check Alignment Next Visit, $84.95. I did not elect to have them do any of these things today, deferring to the next service at 60,000 miles. And by the way, I've never heard any noise from the drive belt. What's up with all of this? Are they just trying to raid my wallet? If this stuff is routinely required, why is it not on the scheduled maintenance list?
