Default Tips after a year

After a year and a half with a new 21 convertible, I've got a few tips to share.

When you buy a new Lexus (or Tesla, or...) have the dealership check the alignment immediately. My LC ate the factory Bridgestones in 6000 miles because the front was grossly out of spec and the rear was moderately out. The 22 year old idiot at the dealership said "this car just sits differently because it's a sports car." I haven't written to Lexus Customer service about a compensatory set but I may, and I'm pretty sure I won't be offered any compensation at all so I'll have to take them to small claims court. Don't assume factory alignment is correct just because your car is nicer than others.

The car had a slight clunk somewhere in the right rear when shifting to reverse and rolling back. After the dealer scratched the paint at my initial 1000 mile checkup, I don't want to take it to a Lexus dealership ever again. After a few months, whatever it was fixed itself. Even if the dealer knew what they were doing (and I doubt "only the master technicians are allowed to work on the LC") it's better not to pull any interior parts if not absolutely necessary. The noise may have been a bracket under the back seat and related trim.

Two stones hit the windshield and left bullseye cracks (3 weeks apart!) which I had filled by Safelite. I'd rather not have anyone replace the windshield unless absolutely necessary, due to risk of distorting interior trim leading to squeaks and trim replacement, paint scratches, etc. The glass does seem easy to chip, as my old Porsche has taken similar hits with no damage.

I don't bother with protection film, except for 3M strips on the extremities of the door edges. The only paint chips have been a couple spots on the front bumper zone, and then a real down to primer chip on the front edge of the hood above the grill. I'd say the 3M door edge film would be a good idea for the hood edge too! Due to airflow I suppose, the hood surface hasn't had any chips. No chips behind the wheels either. I might apply film to the headlights, no chips but it might save polishing them in a few years.

Audio quality is fantastic, but satellite radio will make you think it isn't. Ditch Sirius and subscribe to Amazon Music Unlimited for full quality stream data, possibly also Spotify for whatever you can't find on Amazon. Use a small wired DAC on your phone and the car's AUX input. With a splitter cable you can use the DAC and also plug into the car's USB for charging. Then you'll want a little Bluetooth remote for pause and track up/down, I stuck a coin-size one on the side of the console below the gearshift where it's natural to drop your hand and press (invisible behind your leg too). I'm not sure my sub woofer grill rattles, or if so it's infrequent enough that I haven't yet pulled it out to cut the baffles. Finally, remember that all speakers sound better after hours of break-in on their rubber rings, so if you're not impressed when the car is new, you will be after a few dozen hours of play. You could speed that up by playing pink noise at high volume in your garage, but the car powers down every 20 minutes. If anything, EQ might benefit from a notch of treble, otherwise EQ is great at the centers.

Turn on climate concierge, then turn off AC when it isn't hot summer. Concierge will turn on AC when you first set it, but won't turn it back on after setting AC off. Saves gas and wear!

Most of the fun noise happens under load and between 3000-4000 RPM. Paddle down at every 2000 when decelerating to achieve a fun rev blast and pop. Less pedal on acceleration will extend the noise time and maybe go through an extra shift without breaking the city speed limits, so enjoy slower driving more. Of course on highway on ramps, full throttle is great, and there is an "afterburner gate" in the pedal (I believe the car is designed after planes like old Detroit was, now based on the F-22 with the gold canopy effect on side glass, etc) so with a light foot you'll feel a stop about 7/8 of the way to the floor...which is suitable for common fun speedups. Then press more to the floor and really blast off! Sticking to the gate most of the time may even extend drivetrain life.

Get rid of run flat tires once the first set is bald. Keep a can of fix a flat in the trunk.

You don't need a front camera in the grill, this is a man machine. Get used to the proper standoff from curbs and walls by parking at the right place in front of one, then note where the curb line and wall edge appears relative to the left outside mirror arm. Like airplanes, you need visual references for approach and ground operation.

Comfort mode should be your standard drive mode, due to road quality deteriorating over several decades of decreased tax revenue from the upper brackets. Then set the custom mode to performance for drivetrain with comfort for suspension. Comfort mode keeps the car quiet and barely above idle at highway speed, but power is delayed when you step on it...cruise in comfort, but click the custom button when you see traffic you'll want to maneuver through with instant power. Click back when clear. Save Sport+ for smooth roads and fun cornering with an audience! Body roll is soft in comfort, but good for a big GT car in Sport+.

Do not apply any fabric protector spray to the canvas top, it doesn't need it. If you do, cover every inch of paint and glass with drop cloths.

The self-healing paint does work. At least once, when it's new and your dealer runs it through their 50 cent wash for you. It works when the body gets up to 100 degrees for a few days in summer. Lexus says it'll stop working in 5 years, which may mean 2. I have only a couple lines visible from the dealer wash, and while I can polish it, paint lasts longer the less you ever touch it. Wash only quarterly with the most expensive car soap and buy a new wash mitt/sponge every time. If it's dirty, it's still a better car than everyone else has!

Use 0W-30 oil. Find a small shop that lets you bring the oil, filter, and a new aluminum crush ring for the drain plug. I bought a long floor jack to do it myself, but there is really no way to reach the front center jack point with any jack. Ramps would work but you'd have to make super long ones!

Get a Valentine One radar detector and a mirror mount, cut the power cord and solder the wires to shirt pins. Follow the LC mirror power tap instructions here on the forum (thank you sir!). Even on American highways 160+ is occasionally possible.

Stock brakes are good, but dust is ugly. Pay a high price for a spray cleaner that turns purple, whatever says iron/metal/X/etc, and that will save a lot of scrubbing and wiping. (It also removes exhaust stains on the factory rear trim.) The factory wheels are clear coated, so treat them like the body paint. Liquid synthetic wax or Collinite Insulator Wax helps with dust protection.

When you must let shop workers enter the car, first put painters' tape on both of the door speaker grills. They will always, always, scuff a greasy shoe edge across the fabric there at the front corner, and you'll see that every time you open the door. If you're scuffing them yourself, try Pilates for flexibility.

Enjoy, and never be jealous of Astons or Ferraris. This car actually runs, which saves you time for more fun!

To those who have the carbon fiber door sills - how are you protecting them from scratches? The driver side sill on the 2023 I just bought was scratched up pretty good. The dealer is replacing it. Has anyone PPF'ed the sills? Does that limit scratching?

I don't have carbon fiber door sills, but I do have PPF on mine and have had no scratches from my big feet and limited bending knees.

My CF door sills are PPF’d. I think the PPF installer charged me $80 extra for them.

try this.

it seems the pops and cracks happens more frequently once the oil temp (not thermometer) reached operational temps. Also, if you use gas that has a mixture of ethanol in it seems to pop and crack more than gasoline without it.

just personal experience.

If there's anything I learned over the years - don't ever take your new car in for any kind of anything at the dealership.

Dealership to me is only for ordering the car. Once delivered, sayonara. All service and maintenance will be done by my trusted specialist.

Did this for years and nothing ever went wrong.

Is your trusted specialist able to do warranty work?

Yes. Was the same for my MB back in the day, and the same for my BMW now.

I can't imagine there are no independent Lexus specialists who can't also honor warranty work.

Wow! I have never even heard of any auto manufacturer honoring warranty claims at a non-dealer.

did you own an edsel at some point too?

Two stones hit the windshield and left bullseye cracks (3 weeks apart!)
very sorry to hear but glad you got it fixed to your satisfaction.

I don't bother with protection film, except for 3M strips on the extremities of the door edges.
i assume you think it isn't worth it. obviously a lot of people on thus sub-forum disagree, but you do you.

Audio quality is fantastic, but satellite radio will make you think it isn't. Ditch Sirius and subscribe to Amazon Music Unlimited for full quality stream data, possibly also Spotify for whatever you can't find on Amazon.
plenty of options other than amazon and spotify (i just switched from tidal to youtube music, both are great) but your point is a good one, sirius xm is garbage sound quality.

Use a small wired DAC on your phone and the car's AUX input.
that right there is a terrible idea. the car is most likely taking the analog input and converting it back to digital for in unit processing. better to send digitally in the first place, with either usb, apple carplay, android auto (with a wireless adapter they're then both using wifi not bluetooth) or, last resort, bluetooth.

Then you'll want a little Bluetooth remote for pause and track up/down
not needed if you're not using aux input, you have the same controls on the steering wheel and center console anyway.

Finally, remember that all speakers sound better after hours of break-in on their rubber rings, so if you're not impressed when the car is new, you will be after a few dozen hours of play.
i think that might have been true 50 years ago, but not today.

personally i think the mark levinson audio is very mixed, sometimes it sounds decent, but most of the time it's very mediocre to terrible.

Turn on climate concierge, then turn off AC when it isn't hot summer. Concierge will turn on AC when you first set it, but won't turn it back on after setting AC off. Saves gas and wear!
you won't save anything (this isn't 1965) and running the ac keeps the compressor healthy.

You don't need a front camera in the grill, this is a man machine.
a 'man machine'?

and buy a new wash mitt/sponge every time. If it's dirty, it's still a better car than everyone else has!
ever heard of a washing machine?

Enjoy, and never be jealous of Astons or Ferraris. This car actually runs, which saves you time for more fun!
ha, good one.

thanks for sharing your points of view.
