Okay so between 2008-2016 Which car would be best Audi A4 or A6, Mercedes Benz and model (car not suv) BMW 3 series, Cadillac CTS, or Infiniti G37 sedan? I’ve seen all with 200k+ miles and they were just taken care of. I drive mostly highway so my worries of major things going out such as engine or tranny aren’t a big risk for me I just want to know which of those I can get the most highway out of

I have a 1992 Pontiac Bonneville with the 3800 series 1 engine. I usually only drive it on the weekends and usually only go about 15 mph. Whenever I go to start it up on Friday evenings smoke comes out of the exhaust pipe. I bought some lucas oil stabilizer thinking it would help. I have not put it in there yet. It has 155,500 miles on it with the original engine. Still runs like it came out of the factory, just smokes a little in the Friday evenings.

Hi Scotty, My wife and I just bought a 2012 Lexus ES 350 with 94,000 miles. We had a mechanic check it out before we bought it and I'm in the process of having all fluid changed. Since I don't know a transmission expert I'm thinking of changing the transmission fluid myself...using one of several Youtube videos I've found. (I sure wish you could do a video showing the steps in this rather involved process) My question: Is 94,000 Miles too many to risk changing to fluid? Is to too late to change the fluid without risking messing up the perfectly working transmission? Thank you for all you help!!!

Hey Scotty is it true that there’s a problem with the direct fuel injection in V-6 Honda Accords 2016-2017? I heard from a Honda mechanic that the problems with the fuel injection can cost upwards of $6000 to repair? Is it true? Thanks.

Hey Scotty, I'm wanting to do an electrical fan conversation on my 04 SS Silverado. I've been doing my research, and some ppl say that I need to tune the truck after the conversation, some say you don't. I know I need the fans themselves and the harness and a bigger alternator. What I need to know is, do I need a bigger radiator? And do I have to get the truck tuned after the conversation? Please help, and thanks.

Hello, I have a problem with the AC only being slightly cold on passenger side in this 1995 Honda Civic EX. Here is a link to a photo that shows the pressure readings at 80F http://prntscr.com/odu8ue This was done with the car off and cold. When I start the car up and let it run and warm up the gagues move up, the Low pressure goes to about 50psi and the high goes to around 200psi. Do I need a charge? I have a Remanned Chinese Compressor, put on within the last year.

Hey, how are you? Well, I have a rather odd problem here. I was checking my cooling fans to see why they wouldn’t come on in my '02' Monte Carlo SS. And, I found that the wiring for the fans were cut in three separate places. So I wanted to know, would it be safe to strip the coverings off and reconnect them, or should I just replace the harness?

Hello every one, If Mr.Kilmer is busy, can anyone help me with this question?

I have a quick question and hope you have time help me with it.

I am a student (on a very low budget because college takes a lot), I have a 2005 Camry 2.4l LE, I bought it and been using it daily in the past 18 months, I have noticed that the ATF is very dark so I have asked many people whether to change it or not. Some advised me not to change it because a fresh ATF will have different properties (viscosity and so) and may affect the transmission badly (it may start slipping), their evidence is what is written on the ATF dipstick "No need to replace the ATF under normal driving conditions", Others have a different opinion that I have to change it, otherwise, the dark and old ATF may cause damage to the transmission as it cannot cool it as the fresh ATF can.

I am confused and at the same time very worried because I CANNOT afford a new transmission or even rebuilding a broken one. Also, I have three kids and don't want the car to break down when they're ridding with me. The car has 168K miles.

Thank you so much for your help.

Most Respectfully,

Hey scotty. Changing the oil in my 2010 Ford Edge more often and upgrading oil as you suggested seems to have stopped the issues I had described. However now, my service tech tells me I have an oil leak. Not enough to leave stains, just a thin coat underneath the engine/oil pan. Can't afford to take it to a mechanic yet. What might I be looking at? Also, after a recent road trip, the car makes an odd sound near the right side ac vent on left turns, only when the ac is on. The same area inside the cab now also sounds like liquid is flowing inside upon braking. Hope this isn't too much at once, thanks Scotty!

Hi Scotty,

I have a 2011 audi a3 premium 2.0 turbo with 78k miles. I recently started to notice a clunk/jump when I would accelerate. You can also hear a rattling spinning noise near the engine. I took it to one local shop and told me I needed lower control arms replaced and my crankcase valve replace as well. I wasn't sure so I took it the an Audi dealer service for an inspection and they told me I have carbon build up since I have not been putting 91 octane gas and that's the cause of the hiccups my car's been giving off. I'm not sure if this is worth fixing as each shop wanted about 1500-2000$ to different repairs. any thoughts or comments? I honestly don't know what to do.

Looks like I am in alternator hell. Back in February I replaced the alternator in my 2012 Honda civic with a Carquest alternator from Advanced. I found out within a week after replacing that alternator that it was bad so they gave me a new alternator. Now five months later its having alternator issues again. I am hesitant to take it back to Advanced auto to get another Carquest alternator which will probably just go bad within the year. I was wondering if there is possibly some other underlying issue that's causing the alternators to go bad or if it's just crappy reman Carquest alternators and I should go with another company for my new alternator? If I should get a new alternator from somewhere else where would you recommend?

What is this whine sound? Car is in park happens in park, and in neutral, but not really when the transmission is engaged as much, replaced PS Pump and alternator. I think maybe vacuum leak https://share.icloud.com/photos/05igWpJk-EaYvJhh3BhCCzFrQ#South_Texas_Medical_Center

Hello Scotty! I've been a subscriber for about 3 months now. I just bought a 2002 Trailblazer that was apparently kept in good shape with only 103k miles on it. I've noticed that when I have the mode selector on heat/ac all the way down to only vents, I can hear (which I'm assuming the door actuator), keeps making noise. If I turn the selector just one click up, the noise stops. Do I need another actuator or does it need to be reset somehow?

Replaced both 02 sensors, new spark plugs, coil number 4 , 4 fuel injectors.. Cleaned throttle body, MAF, battery cable connectors. Smoke tested the intake to confirm no leaks after checking for compression,vacuum leaks, EVAP leaks into the intake, Fire and fuel. Tested engine coolant sensor. Problem continues...this has been going on for 6 months. Getting desperate. Rough idle on 2011 rav4 4x4 2.5L 4 cyl

Hello Scotty,

I own a 2016 VW Beetle. I live in Canada. This week, May 6, I brought my car to the VW dealership to swap the winter tires for the summer tires. During the day, the dealership called me up explaining that the tire swap was done and that they made a brake system inspection. Good news, my front brake pads have 8mm left and the rear brake pads have 9mm left. Then, The dealership rep suggested that I approve a $200 preventive brake maintenance procedure. I asked them about the procedure and they explained that they would take the brake system apart and they would clean all the components using sandblast and put everything back together afterwards. I told them that if the brake system is not broken; please don't fix it.

Since DieselGate, MonkeyGate and such, my trust in the Volkswagen company has been shattered. I do not trust them for anything and I think most everything they do is a money grab.

So, was I right to pass on the brake system maintenance procedure or was that procedure a legitimate thing to do once or twice a year?

Thanks,

-- Michel

Hey Scotty.....I'm working on a 2007 Chevy equinox v6 3.4 L AWD and it's been overheating lately. Before the current problems I've replaced the thermostat, flushed the entire coolant system. After the overheating issue I replaced the coolant temperature sensor and tested the fan relays to make sure they work. No leaks....coolant full. The mechanic did switch from low mileage coolant to high mileage......What else should I check to determine why it's overheating?

Scotty, I have a 2006 ford expedition limited 5.4L v8. I've changed the plugs and coils. It would shudder at idle and shut off. I changed the atc solenoids. The transmission is 2 years old. It cranks up, but wont hold idle speed and shuts off. No codes showing. What do I check next? Thanks.

I have a 2003 Mitsubishi Eclipse GTS. There is no Cabin Air Filter in this one. My AC will not take in any freon. I was told I needed an AC Expansion Valve. I purchased it. Looking at videos on how to replace it in my vehicle says I have to take the dash off, drop the steering column in order to get to it. Is there an easier way?

Hi Scotty,

       My airbag light is constantly flashing on my 2006 Toyota Sienna.  I have generally been able to reset it by unplugging the yellow airbag connectors under my driver's and passenger side front seats, but it doesn't seem to remain off for long.  I believe that the issue is with the passenger side - side airbag connector and/or wiring.  There is a TSB for the problem, and Toyota makes a wiring repair kit for the issue.  It looks like you have to rewire the 2 connectors and then splice the other end of the wires into the circuit.  I can't find any videos on how to do it though.  Can you help?  Thanks.

Hi Scotty! What's the best way to keep my door seals lasting longer?

When it comes to the rubber door seals is there a difference between the CRC Siilicone Lubricant (https://www.amazon.com/CRC-05074-Heavy-Silicone-Lubricant/dp/B000BXKZUG) or Armor-all protectant?

What method(s) would you recommend?

Thanks Scotty!

Scotty,

I have a 2015 Honda Accord with a V6. I recently got a transmission fluid 'drain & fill' at 50,000 miles. The dealership recommends that I get a flush at 100,000 miles. Their idea of a flush is drain & fill three times and charge me twice as much. Should I just get a drain & fill at 100,000 miles or go with their recommendation for a flush? Thanks Scotty!

What do you think about a 2016 - 2018 6th Gen Camaro with under 10k miles? If not that, what could you recommend? Thanks!

Hello Mr. Kilmer,

I'm a college student and daily drive a 2006 Ford Mustang with a V6 engine, 5 speed manual transmission, with 136,000 miles on it. I've been having an issue with the transmission, when I shift into third gear I have to do it slowly to avoid a grinding noise. Once the gear is engaged there is no noise or problem. After researching online I suspect it may be the gear synchro but don't know. Would it be wise to pay to repair the transmission, replace/upgrade it, or to sell the car? Would really appreciate your help and advice. Thank you sir and have a blessed day.

Regards, Andrew

Hi Scotty I bought a 2005 Mazda 6 wagon a year ago for 2600 ever since I’ve been having to repair something on the car. There’s a laundry list and I’m tired of putting money into it. I’ve put about 600 to 700 dollars into it. Is it time to sell or just junk it?

Hi Scotty? Can I ask you a few questions about our suv? Our air conditioner button/switch is not working anymore. In fact we have to tap under the dash board area to get it to turn on. Is that safe? A few months ago the car kept turning off when we tried to go up hills. we eventually got the car services and changed the coils. But from the beginning the car’s muffler has a lot of smoke and we have to keep putting oil in the vehicle every week. That’s not normal. Why is the oil burning so much? There is no visible oil or coolant leaks? Yesterday we put some royal purple 10-30 oil in the car and it drove good. It even didn’t start smoking at first. But this morning the car shut off then we turned it back on a big puff of smoke came out the muffler. Then the car started driving normal again?
