Q: I will be
driving in Utah, Nevada and the valleys of eastern California, where
temperatures above 110 degrees are not uncommon. If I start the day
at the recommended max tire pressure listed on the door placard, do
I have anything to worry about, or should I bleed the tires, and how
much? Also, a pretty good pressure gauge always gives a reading 1 or
2 pounds less than the built-in tire pressure sensors. Which is
likely to be more accurate?

ever, bleed air from your tires. Although the tire pressure may
increase a bit while driving, it will be much too low the next time
you start out. Inflate the tires to the pressure stated on the door
placard and leave it there. The tire pressure sensors are very
accurate. Manual tire gauges, not so much, but close enough.
Incidentally, some folks mistakenly think that the maximum pressure
figure molded into the tire sidewall is the inflation pressure, it
Q: The manager
where we bought our 2016 Ford Fusion hybrid mentioned that Ford is
thinking of dropping support for their navigation systems in their
vehicles since so many people have a similar system on their
smartphones. This idea seems ridiculous since using your phone while
you drive is less safe than using your vehicleís navigation
system, though Ford seems to be coming up with more than its fair
share of bonehead ideas recently. Any truth to this rumor?
to the Ford website: "On August 1, 2018, the SYNC Services
subscription service, along with the SYNC Destinations mobile app,
was discontinued for 2008 through 2016 Model Year vehicles equipped
with SYNC, SYNC with MyFord, SYNC with MyFord Touch, or SYNC with
Voice-Activated Navigation. If you subscribed to this feature, you
can still take advantage of the many features available through your
version of SYNC. SYNC Services relied on technology that is no
longer being supported. While this technology was useful when the
feature launched, it is no longer the best way to support owner
needs. We will continue to focus efforts on new technologies, such
as FordPass SmartLink." Talk to your dealer or go online to
switch to the new technology.
Q: Iíve got
a 2008 Honda Pilot with about 150,000 miles. Intermittently when
stopped at a traffic light, Iíll hear a dull "thump"
coming from the rear of the car. Itís loud enough to make me look
up in my rearview mirror to see if anything hit me. It only seems to
happen when the car is stationary, but in gear, with the brake pedal
depressed. I have never heard it when the car is moving, and it
doesnít seem to be related to me depressing or removing my foot
from the brake pedal. My Honda dealer kept the car for a day, but
couldnít recreate the thumping. Techs checked the car over,
including the brakes, and found no issues. Any suggestions?
is moving and hitting something else. Sure, that sounds simple, but
so is the solution. We have a hunch that itís the exhaust system.
At idle, the car has low frequency vibrations, especially while in
gear. There may be a loose hanger or a break somewhere in the
