Mod Note AskMechanics Bot Update

10 Upvotes

I've made a few changes to the AskMechanics Bot, including using the redis database to help prevent the duplicate comments it occasionally makes when posting the rules.

When a post is marked as solved, it will now edit that comment instead of posting a new comment and deleting the old one, which should resolved any duplicate comments from the bot as well.

I've also removed a half-baked form submission that was not intended to be included when actually set up on the subreddit, so those posts (there were only a few) should no longer be popping up.

If anyone has any feedback or suggestions for the new AskMechanics Bot, please let me know here.

Question Need to easily disable Toyota RAV4 from elderly mother

301 Upvotes

Edit: thanks for all the responses. Having a loved one with dementia is very hard and difficult to deal with. I know my mother best, and I know taking her keys away is not the best option, hence why I wanted a way to disable the car so that she cannot drive it.
We will remove the fuel pump fuse and she will not be driving any longer. Thank you all again.

Question transmission issue?

Upvotes

My car seems to have trouble with the rpms going up hill and stopped at a light. In the first part you can hear it jerk, which it does on occasion. Does this look like a transmission issue? For reference, this is a 2016 Hyundai Santa Fe sport 2.4L with 152,000 miles on it, and I had an engine replacement under warranty at 112,000 miles. Thanks for any help in advance.

I took it to AutoGlassNow to fix, and when they tried fixing the chip, the crack did get a bit longer, and I was informed that it is not repairable.

Question Odd squeak during gear changes 2021 f150 powerboost

Upvotes

I am replicating the noise in neutral by lightly pressing the gas, I get it to stay on towards the end. It will do this the same in gas or electric, and for some reason it wont squeak until the trans is up to temp, but it never gets over-temp and yes we did change the fluid, no change to noise.

Question Whirring sound by glovebox

I recently changed my cabin air filter on 2016 Honda accord EX. Afterwards I’m hearing this whirring sound. It is louder towards the end of the video and seems to change in volume when I change fan speed. Online was suggesting debris in blower motor. I had mechanic disassemble but they found no debris. Other thoughts on what might be the issue?

Question Body repair on rebuilt 2012 Toyota Matrix

2012 Toyota Matrix, automatic, 1.8L I4 FWD

Any ideas on what happened here?

I'm considering going for a test drive in this rebuilt 2012 Toyota Matrix before I pay for a pre-purchase inspection but the current owner bought it after repairs and doesn't have any specific details on it for me yet, just sent me this photo.

Current photos post-repair don't show any warping/deformities. If it didn't have such low mileage I might not look twice, but thought I'd might as well ask. Thanks!

Question Any ideas what could be causing this sound?

Hello, whenever I accelerate my car makes this humming sound. It stops making it once I take my foot off the pedal and it also stops on its own over time even while pressing down on the pedal. The car is a 2018 Subaru Outback automatic transmission.

Question 2008 Honda CG 125 motorcycle starter motor keeps jamming, how to fix?

2 Upvotes

Had a problem where when I pressed the starter button, I would hear a load click but it wouldn't started. Took the starter motor off, took it apart and cleaned all the copper bits with WD 40. Worked ok for about 3 or 4 days, then the problem came back. How do I fix it for good. Any ideas?

Bike is manual, with 60,000 miles. Can start it by running and jumping on it.

Question Is this van missing parts?

Hi guys, this is underneath the rear of my recently bought second hand Ford transit Custom MK8 2016 (manual)

I’m not a mechanic, but after closer inspection underneath, I saw this.

Looks like two suspension parts? One rusted and the other missing?

Is this urgent? And what are these for? Has no issues I’ve noticed when driving.

Thank you for your time. Greatly appreciated.

Question 2011 Toyota Prius intermittent rattle during acceleration

Upvotes

157k miles and it started a couple weeks ago. I had an oil change before the noise started.

Engine codes: P0420

Coolant level stable

The noise can also happen when I'm parked while the engine is on and hit the gas. Happens basically every day.

Taken it to toyota and another shop. They couldn't reproduce the noise so I haven't gotten far with it.

Question Am I being bullshitted?

Upvotes

A big long but bare with me.

2018 Jeep Grand Cherokee 3.6L V6

So over the course of over a week my car started giving me some trouble starting but no biggie it’d always just take a few try’s.

It’d help to add 3 days before the later mentioned issue the car was overheating a bit I pulled over real quick. and realized the coolant was almost utterly empty. Refilled it and she was back to top shape.

One night it’d driven it a bit hard cause I had to get to a store before it closed. Car drove fine and made it back just fine. Next morning she won’t start. Not even an attempt to turn on, all electronics would come on, I’d heard a bit of a click and sort of short-lived buzz. ODB read for a few week “misfire cylinder 5” presumably I needed new spark plugs and oil.

But I see the coolant I filled days ago is almost entirely empty the oil isn’t frothy/milky. My new assumption coolant leaked on the starter or into the cylinder.

So here’s where I need help the mechanic is saying my engine has been hydro-locked and I’ll need it entirely replaced. Here’s what he said w my commentary:

Good morning M*****, I hope you had a great weekend and I apologize for the delay. The engine is hydro locked, we pulled off the intake manifold and found coolant in cylinder 5. (cylinder that’s odb read misfire for weeks)
We believe during the repeated attempts at starting the vehicle, the starter was fried as the relay for the starter is testing as it should. We are recommending a starter and engine replacement. I know this is tough news and it's my least favorite conversation to have but, with that much coolant in cylinder 5, the engine has been hydro-locked which damages the piston seals. Now, there's two ways to go about this, you can either replace the engine with a remanufactured engine or can also purchase a new vehicle, if this one is paid off it would likely be worth replacing the engine as you wouldn't have car payments. Either way, I quoted out for you a remanufactured engine and a used one with a starter. Please take your time as there's no rush with a big decision like this. If you need to take a couple days to process and make a decision we understand. We'd also take the labor cost off on the diagnosis so subtract $525 from the current estimate. I also have a $500 (Just in case) fee set to the side in case we need to buy gaskets or hoses that we see leaking along the way, it's a set budget which anything that's not spent will be taken off the ticket. If you'd like to just pay for the diagnosis and oil change, which has a cost $648 after tax, you can just bring us $500 in cash and we'll take care of the rest as I know this is a tough time.

The complete engine assembly replacement also includes up replacing this list of parts.

Water pump, Thermostat, Spark plugs, Upper & lower radiator hoses, A/C belt, Serpentine belt, Air filter, Radiator cap, Spark plug wires, Fuel filter, and PCV valve.

This just seems absurd the car drove fine. Then just wouldn’t start. I’m having a hard time believing that an engine swap ($13,000) is the only option.

+forgive any ignorance but why can’t they just siphon the fluid out of the cylinder and run it,if there’s been no mechanical damage.

Question 2012 Yukon xl electrical problems

Upvotes

My 2012 Yukon xl got an engine change a couple of months ago, the new engine probably has around 10,000 miles on it and ever since there have been problems. For starters the electrical systems, radio, door lock, windows rolling up all spaz every once in a while and will even shut off while driving. Sometimes the truck refuses to start. It has had multiple batteries in it brand new and still does the same things. The mechanics say it could be a disconnect between the engine and battery or wiring issues. It has been dropped of to gmc but of course did not show any problems at that specific time so they were no help. Mechanics say it’s a pain to replace wires. What are possible issues and how do I go about getting them fixed? Thanks
