Charging a diagnostic fee is common in the U.S. industry. In this case after testing the CAN bus, checking DTCs and power/ground connections the display unit is being replaced under warranty. The up front diagnostic fee should be refunded and should be so stated in your repair order paperwork.
The Z Sport comes with an open differential so there's no clutch friction material to accumulate and need frequent gear oil changes. Manual gearbox oil does deteriorate but not very fast. Lots of S-Mode downshifts might warrant more frequent changes.

The graphic looks like the forward and side hazard warning radar is unhappy. This system is independent of the parking sensors and I can tell the side part is working by the amber light near the outside mirror when someone passes.
Stuck rotors and alloy wheels get pounded loose all the time in...
I enjoyed the above video by Lake Speed Jr. He tells it like it is & is extremely qualified. He helped Joe Gibbs win NASCAR championships using a special synthetic oil that didn't overheat while drafting. The competition overheated and had less horsepower to pass while the drivers for Gibbs...
Keep in mind that viscosity is only part of how well oil protects. I've seen tests done in Germany where a high quality 0W-16 gave less wear than a generic 5W-30 under identical autobahn & short trip driving. Because of direct fuel injection, our Zs get some fuel dilution and soot contamination...
One thing to watch is the oil filter bypass valve spec. Racebox posted the Nissan bulletin about this late last year. You want a Nissan 15208-65F1A or B. Wix, K&N & others use the VQ35/37 engine's lower spec which might bypass dirty oil into circulation when used on our VR30. This is mainly only...
I checked into this and found the recommended fluid for the stock Performance LSD is mineral based GL-5. Both Pennzoil and Torco have such products with Torco recommending adding their "type F" friction additive. Probably any GL-5 gear oil will work if it has an LSD clutch friction additive...
I think this bleed pattern came about years ago when dual master cylinders split the brakes diagonally. This front to opposite side rear connection was to keep the car stopping straight if half the system failed.
I like using a tool with external brake fluid reservoir that pressurizes the...
Toe alignment plays a huge role, especially with wide low profile tires. Be sure to compare the rear to front as there could be an unfavorable additive effect at their spec limits. Something else I'd check is the engine compartment under tray to make sure the air flow is smooth all the way back...
Keep in mind the tach is showing a graphic representation of what the digital electronics are doing. Nissan likely sets the rev-limiter conservatively and may be adjusting for gearing and rate of RPM increase, like lower in lower gears.
Having a range of over-rev like to 8.5k is just old school...
BG Products have a good rep in the service industry but DO incentivize their sales at dealerships. Additives are like UFOs and ETs - 99.9% are complete BS. It's the other 0.1 %, like BG, that are interesting!!
MOA is mostly an antioxidant and not really needed if you change a synthetic before...
I heard a very light whine after start-up only once with my 6MT. Car hadn't been started for 2 weeks and the sound went away after about a minute. Didn't notice if the clutch had any effect as I let the engine idle in neutral.
I checked my Z's steering rack travel and feel. There is no column lock, at least on the manual trans, so this can be done easily. I found 480 degrees from center to each stop = 2 and 2/3 turns lock-to-lock. Subjectively the Z steering feel isn't as communicative as a 4th gen Miata or Fiat...
That does sound like front suspension geometry with differences side to side. It might be a problem in the electric power steering assist. If you have access to a safe large dirt area, try the steering with the car rolling in neutral gear with the engine off. The steering will be stiff (high...
I've used clay bars, foam pads with clay-like coating and machine polishing with a clay-like pad. I check the paint feel first and decide which to use based on how much contamination and the area size. They all work the same and the mitts are similar to the rubber clay-like coatings found on...
@AlfredoGonzalez What speeds are you noticing the difference turning? Is it normal left & right in residential neighborhoods or faster canyon carving pushing the suspension?
The dealer's scan tool may still be able to read a stored diagnostic code so worth a try. Most cars drastically reduce power if the wheels really spin and lots of traction/stability sensor input occurs. I've never heard of one refusing to go into drive or move.
I sometimes drive my manual...
Most octane boosters contain MMT (manganese) which auto makers frown on due to possible emission control damage at high doses. Low doses won't even discolor spark plugs let alone the reddish looking tailpipes I've seen at track events. I've used Boostane and Torco street formulas in supercharged...
I'm surprised you didn't get a warning. Modern cars either show something on the display or the pads have mechanical screechers. Backing plates on rotors is bad news.
Pad wear is so subjective. Driving habits like faster acceleration in stop & go, even at low speeds, really take a toll compared...
@labornurse Warranty for brakes and clutches can be iffy and often goodwill, despite abuse. The pads likely didn't bed-in and left an uneven transfer layer on the rotors. I've heard ceramic pads work almost exclusive by transfer adhesion hence the low brake dust.
