I drive a Toyota Sienta Hybrid, 2017 make.

Regular mechanic told me the engine / motor oil (he used synthetic type)
for hybrid is different from non-hybrid cars.

Q1:
What about spark plugs (I'm looking at iridium) : is it different from non-
hybrid cars'  iridium spark plugs?

Q2:
Can point me to an ebay, Amazon or Aliexpress link that sell Sienta
Hybrid's iridium spark plugs?

My Galaxy Note 4 (already updated to latest Android) tends to lose
connectivity to GPS (even though the connection to cellular/mobile
data network seems to be intact) while driving for 3 to 30 secs.

I'm using Waze.  The disconnection can happen even on a bright
sunny day (ie don't have to be cloudy/rainy days) or in open
highway (ie not while going through tunnels).

The same SIM card was previously used on my Galaxy Note 2 for
for almost a whole year previously & I never had this issue.

Is this a known issue with Note 4 or the Telco ?  Maybe one way I
can test this is to use the Note 4 as a hotspot (tethering) to an
iPhone & test to see if Waze/GPS  disconnects intermittently:
map is still there but there's a red alert message that 'connection
to GPS is disconnected' at the top of the screen.

I only noted 2 changes:
1. I switch from Note 2 to Note 4 at around the time I disposed
    the old Honda Airwave to Toyota Sienta hybrid: not sure if
    there's something in Sienta that interferes
2. Note4 tends to get very heated up while Note2 is not that
    hot while Waze is in use: I've since taken out the backcover
    of the Note4 (& used scotch tapes to hold the battery & SIM
    card in place) when in use so that the heat dissipates

I'm trying to explain to my wife over the phone how to drop in a seat on our 2000 Chevrolet Express 3500 Van and lock it in place.  Once the seat is in place how do you use the locking pins to secure it?  This is a new van she picked up so I have not ever done this procedure.

I have 2017 GM Sierra CK 2500 Pickup Truck. Can you suggest me something which is cheap I can put on the bed and sleep under it.

I installed a new aftermarket stereo in my 01 Tahoe. Everything worked but when I turned the truck ignition to on from accessories... I lost all sound. I pulled it out, opened my door to reset everything and plugged the stereo back in. Started the truck and the same thing happened. I can only get the sound back on by turning off the truck, open door for reset, unplugging stereo, plugging stereo back in and turning truck key to accessories. I tried the deck in my buddy’s 01 Tahoe nod it worked fine. I tried putting his deck in my truck and the same thing happened. I put my stock one back in and it works fine. I’m completely stumped by this?! Help?!?

Ford ka 2001 1.3 not starting fuel pump changed and serviced at garage took car back to garage did not do a non start once in two weeks got it home parked on slope driveway would not start

I have a Samsung Galaxy S7 and I use Android Auto to connect to my car.  I recently lost the ability to use the voice command "Ok Google". I can still prompt it if I touch the mic on my car dashboard and then voice command whatever I want it to do..

Note: That this has worked before with my current set up. It may of stopped working after a recent phone update, but I can't be sure.

My settings in Android Auto are on to allow voice command. Are there any other settings that might be causing this?

What's the best way to troubleshoot?

Trying to find out how to replace my alternator on my 98 maxima. I am trying find a picture that shows the alternator and the placement of the upper support bracket. When removing the old alternator I did not take note of the bracket. The working space was so tight, Having a tough time figuring out where the bracket goes and placement of the replacement alternator. I have been googling for days trying to find a video or picture but can't find one. If someone could point me the right direction Iwould greatly appreciated t.

My diamante 98 just had replaced the battery and the alternator and i had it parked for like 2 to 3 months and now when i jump start it after i drive it for a bit and check a few hours later all the power is gone again i already checked the fuse the main relays and everything is fin even when i get it turn on the car works fine and if i turn it off and then turn it on again it does turn on but if i leave it for a while dead again and for some reason when i try to jump start it again it takes a long time for the power to go through the car why would that be

Just take delivery of Sienna hybrid & realized it doesn't have child-safe lock like Altis & Airwave.

My intellectually disabled autist teen son tends to open the door whether it's in motion or at
traffic light.  Is there any way to go about this so that in the event there's nobody sitting at
the back with him to watch him, there's a safety measure to prevent him from opening the
passenger door

Refer to earlier posting where my Honda Airwave 2009 overheated due to a thermostat issue : after replacing
thermostat, for the first few days, the car had very bad frequent 'coughing' which became almost unnoticeable
after a few days.  

For the last 1 week, this 'coughing' / misfiring returned but not as 'violent' or frequent as when the first few
days after the thermostat got replaced.

As I'm trading in this car, I'll need to get it fixed quickly otherwise the dealer is going to (mis)claim it's a major fault
& offer a much lower trade-in value.  At lower gears like S or L, I don't notice this 'coughing' (or perhaps it's not
noticeable), it's only at D gear that it's noticeable the last 1 week.

Q1:
What are among the lowest cost components I could replace first?  
Spark plugs or ?    I just got the gearbox replaced about 1.5 months ago.
Is engine mounts the likely cause & if so, shouldn't it manifest in this 'coughing' at S or L gears as well?

Q2:
Or how can I narrow down the root cause?
