I paid a visit to my Nissan Dealership for the second "Free Checkup" today.
Second Free Checkup is supposed to occur at 15,000km or 18 months for my Nissan Magnite. I had only driven it 13,321 Km in 18 months and so it was time for this checkup.
Here's how my experience went with my second free checkup. (The first free checkup was just tightening a few bolts on the front suspension sub-frame at 2,000km mark)
I went at 10:00 am and was made to wait for about 20 minutes before I could actually get my details entered into their system and a service advisor asked me to come and check the vehicle together to listen to whatever complaints I had.
The main problems I was facing were:
1. The TPMS system had shown the position of puncture and deflation warnings in the wrong tire location. This was because I usually get my rotation, alignment and balancing from my neighborhood tire guy who does an excellent job. But he can't re-program the new position of the TPMS sensors. I realized this back in October when my left
front tire had a puncture but the system threw a deflation warning for the left
rear tire.
2. The feed for the front camera cuts intermittently. It cannot be replicated, but I had a recording of it not working while driving to work once and I showed it to them.
I didn't have any other complaints. I did want to get my Engine Oil changed though. My first free service was at 8,156km at 1-year mark and I only managed to drive 5,165km in 6 months.
The service advisor wasn't too keen on it though. He insisted it was not needed (even though I made it clear I would pay for it). I do not understand why they didn't jump at the idea of a paid oil change though! (It could be because they're always fully occupied and understaffed)
The workshop had at least around 30 to 50 vehicles.
I stayed with my car throughout the entire process to document it.
Free Inspection Process:
The vehicle was sent for wash right away. The wash and vacuuming took about an hour. Then there was a bit more waiting around till it was taken up to a hydraulic lift bay by a technician.
1. A technician jacked up the vehicle and removed the front wheels.
This was the condition of my brake rotors. Nothing concerning. Just regular wear.
He tightened a few bolts for the lower control arm. When I asked him why, he said, they usually get loose and they tighten it.
Note: He didn't use any torque wrenches for this.
2. He then removed the brake pads and inspected them for wear
There was sufficient brake material till the next service at 20,000km or 6 months. The groove is clearly visible and I still seem to have 3 to 4mm of brake material left.
3. He then proceeded to sand off some brake material (Supposedly to eliminate some brake noise)
4. Subsequently he applied some battery grease to the ends of the brake. Ideally they should have used brake caliper specific grease for it. But I didn't protest this.
Note: He didn't apply any of it to the back of brake pad plates. Only to the edges where it moves in and out (perhaps to reduce some friction during movement). I still think this step was not confirming to Nissan's specifications.
Then the wheels were fitted back.
5. Some other technician came and filled distilled water into the washer fluid reservoir and the coolant reservoir (even though the coolant level was already above max).
6. Then they proceeded to over-fill the brake fluid too (which was again above max level already!)
Again, I didn't protest or make any comments on these practices but it still irked my OCD-ridden brain about how they were not following the manufacturer specifications on fluid levels.
The engine oil level was checked and it was exactly at the center between the high and low mark. (I regularly check this level so I already knew where it was). I specifically asked the technician again if I should get the engine oil changed and he said it was of the correct color and consistency. I didn't press further for an oil change.
This concluded their mandatory Nissan-notified version of the second free inspection and we went for a long drive during which I informed the advisor about the TPMS issue and the front camera feed going out intermittently.
TPMS Issue Resolution:
In my previous posts on this forum
https://www.team-bhp.com/forum/offic...ml#post5857802 (Nissan Magnite Review), I had questioned if Nissan actually uses internal TPMS sensors. Today, I got my questions answered with proper evidence.
Nissan did use proper TPMS sensors that are embedded in each of the wheels. How do I know this?
The wheel technician (there's a separate guy for everything at this Nissan dealership!) came armed with a Laptop and a OBD scanner.
It is basically Nissan's internal diagnostic tool called "Consult III Plus"
https://m2kinc.com/product/nissan-di...-kit-with-vi3/
He attached the "Vehicle Communication Interface VI3" with the OBD port and the Consult Plus software automatically detected the interface. He had to choose the vehicle model and manufacturing year on the software.
Then he used a hand-held device that read the signals from each of the wheels on all 4 corners. There were specific IDs associated with those TPMS sensors for each position. This handheld device stored the IDs of each of those TPMS sensors inside it which could later be recalled from its menus.
The process is similar to what is shown in the below video
Nissan Technician used "ALTIA KV4S10 5503" to learn the positions of the sensors and then used the data recorded inside it to feed it to the on-board car's computer manually.
Below is the video of what the technician did. I recorded the process and it shows that he had to manually enter the serial number or the ID of each sensor to the correct position corresponding to each wheel into the Consult III Plus software and probably had to "write" this information into its RAM or something.
Now the wheel positions are correctly stored in the car's on-board computer and it would no longer throw incorrect warnings for the deflation warnings. I just wish Nissan had used a better sensor rather than just a deflation warning sensor. They could have easily procured sensor that gave actual pressure read-outs rather than just a deflation warning.
Also, they didn't have to make this process so "proprietary". I think, no one else other than Nissan's technicians can re-program these unless they have the Nissan's Consult III Plus software subscription and it is not cheap! This is a very "Apple-like" thing to do to keep customers from going outside of their official service centers! It is very anti-consumer.
Something as simple as re-programming the TPMS sensors should ideally be user configurable within car's infotainment system and shouldn't even require such specialist equipment! It is just wasteful engineering!
Intermittent Video Feed Issue Resolution:
The video feed to the 360 camera view is via 4 wires that come from the camera to the infotainment system and they are connected via a coupler system as shown below
When the technician opened the coupler, a few drops of water came out!
This was apparently a common problem! When getting water washing done, please ensure that you don't put excessive pressure water above the Nissan logo because that's where this coupler resides clipped into the front bumper
The technicians used pressurized air to dry out the terminals and attached the coupler back to its place. I hope this fixes the intermittent feed issue from the front 360 camera.
Once these issues were dealt with, I asked them to grease the door checks and the battery terminals.
Then I had to wait till I got the gate pass issued.
This entire process took 3 hours. I was not charged any money for this free inspection.
As per Nissan's official documentation on their user manual, the following items should come under their second free checkup
Under the INSPECT category, the following items were listed. (I've marked which ones were done and which were not done alongside each item)

Body Corrosion (Not Done)
Final Inspection (Done)

I feel like Nissan could improve their processes further to ensure less wait times for the customer.
Nissan should also include each of the items on their inspection and service advisory from the user manual as a checklist item that they need to finish before handing the vehicle over to the customer.
I know it is wishful thinking to expect all such attention to detail, but as customers I think we have a right to expect the best from the technical services industry in India even though it is quite bad at the moment.
I hope the write-up wasn't tool long but I wanted this experience documented here for my own edification for future. The more I learn about my vehicle, the more confident I become as a user of my car!
