Recent friend of Linda's asked for noise help on a 2013 Toyota Sienna van. 3.5 engine and is a timing chain engine. I heard a louder noise at the front that was after was started after sitting overnight and diminished as the engine ran. I told her the timing chain tensioners were likely bleeding off and were gonna need to be replaced along with timing chains and gobs of other stuff. But there was also a constant rattle noise at the front that was hard to locate, even with my mechanic's stethoscope because of very tight access at the engine front. Was either the belt idler pulley or the belt tensioner pulley. I said that the timing chain tensioners will only get worse and can damage the engine when the chains go. Also, the engine and transmission and sub frame have to be dropped out of the bottom for the timing chain work. I got a special discount worked up for her at the Toyota dealer. She had the water pump replaced instead and then asked me for advice about other things like a window motor. The vehicle has 95k miles on it and can be fine except she will not listen. I had told her to decide whether to keep the van or not. She wants to keep. I said to do the engine drop and timing chain and tensioners work and the water pump stuff at same time. She had another shop do the water pump instead. She has the money. She is loaded. I told her the window motor job and anything else will need to be done by someone else. I will not work on it any more. Don't ask for my opinion and then do the opposite and then come back to me. That is just trouble waiting to happen. I don't want any part of it. Friend of Linda's or no friend.

My mom was like that. I'd warn her about issues, and she'd just keep driving it 'til it broke.

She had an early '70s Fury with a busted sway bar mount, IIRC. It kept pulverizing her oil filters every few days.

She didn't fix it 'til I refused to go replace her filters anymore.

Just had something weird happen. I was doing an oil and filter change on a 2022 Toyota Prius XLE, for my landlord's son. Installed a new oil filter and reinstalled the drain plug with a new Toyota drain plug gasket. I was getting ready to reinstall the splash shield small 3 attaching bolt cover and all of a sudden the engine started all by itself. The mechanical engine, not the hybrid side. I crawled out from under real quick and shut the engine off. before shutting off, I noticed a warning banner that said, "HYBRID SYSTEM MALFUNCTION-SEE DEALER". Shut off and refilled oil. Restarted and engine is quiet and running normally. The hybrid system malfunction warning was gone.

Checked for codes, found none. Made son aware and he said that had never happened. I looked and there was a video that said the engine can start by itself because the hybrid battery could be low. The original hybrid battery is 4 years old, almost 5 years. I checked and the hybrid system has an 8 year warranty and the battery has a 10 year warranty. The son is gonna see the dealer.

Anyone heard of this before?

The reason has been figured out.

While I was out from under the Prius getting the new oil filter and the new drain plug gasket and correct tools needed, Linda and I ran thru the lights and when I got out of the seat I did not turn the ignition off all the way and then while under the vehicle and changing the filter and draining oil, enough time went by, that the lithium battery drained down and the engine started to do a recharge. Same thing can happen when sitting at a long stop light or stuck in traffic and while sitting there, nice and quiet, the engine will start up to keep that lithium battery up.

Crisis averted.

Thank God you weren't hurt. ;)

When it rains it pours. The widow of an American Legion friend has a 2005 Tahoe LS that I have worked on before and documented here. She called me the other day and has owned 7 years and never did brakes. Is worried and the brake dust is making wheels dirty. I said ok and she brought by money for parts. Decided to do the oil change too and I noticed the foggy plastic lights and we added that. So, parts ordered and coming for the lights, Got oil, filter, rotors, pads and hardware at O'Reilly. Likely do the job Oct.17th or 18th.

Then, my neighbor across the street, I did the oil change in his 2006 F150 4x4 that we did an engine in about 1.5 years ago, had pulsating brakes and last brake work, front and rear was approx 75k miles ago. Gonna do his brakes all around maybe Oct. 10th or 11th.

Then, today, Linda's dog club friend, with a 2013 Toyota Sienna called and is on the way here now to have me road test for a soft brake pedal.

I think it is something in the water.

Did you find out if there’s a service mode for future maintenance that will prevent this? Imagine if that happened while you had some major components off the engine.

I had no desire to go further with the investigation. Just gonna be real careful moving forward. Guaranteed not to forget that episode.

But that is a great thing to go ahead and do some research on.

There is a maintenance/service mode that I found and there is several videos at you tube that say the same thing. Thanks for asking me to make me go looking.

It is not a quick process and several things to remember but is very much DOABLE.

Just heard back from ALL involved. The two brake jobs will be done: 2006 F150 4x4 on the Sunday the 11 at 10 a.m. and the 2005 Tahoe LS on Sunday the 18th at 10 a.m.

All brake parts here for F150 and all brake parts here for Tahoe. Oil change parts here for Tahoe. Rest of Tahoe lights parts will be here end of week.

The 3rd possible brake job, on the 2013 Toyota Sienna, was not needed. No leaks, fluid full and clean, all pads were at, at least 60% to 70% and could even still see shiny hardware and even the lube. The road test was uneventful. Smooth braking and no noises or pulls. I did the road test thru a large neighborhood and on a local Hiway with slow and panic stopping.

Looks like October will be decent enough money maker with the brakes and the usual oil changes and check this/that calls I get every month.

If some members do not know, Eugene, Oregon is one of the hippie havens left in the USA. The 70+ years old Toyota Sienna owner is a pig when it comes to the inside of the Sienna. She has 2 big furry white Pyrenees dogs and plenty of their hair is all over the inside as well as lots of filth and dirt. I would NEVER EVER do any work on the inside of this Sienna. I pulled over and shot these pics while on my road test:

I accidently had two sets of Snap On PPR708K roll pin punch sets. I advertised on CL and FB and sold in 2 days. Went to meet the buyer and noticed the p/s rear window was 1/2 way down. Master switch, no noise and no movement. Sold the set and came home and found that if I used the door switch it made a binding noise, up or down. Needs a new motor/regulator assembly. See the thin cable bound up in the cracked area and that area spreads apart a little bit when binds up. Have done them before. Gotta fix the Tahoe for once. hardly ever get to do that. Preliminary pics for now.
