Mahindra XUV700 (AX7L D AT) Ownership Review: The Silver Surfer

Nov 19, 2014
Trivandrum , Sydney
As we are enthusiasts, I suggest you a small tip. If possible get a copy of Service/ Workshop Manual of XUV700. It should be available if you can be in a good rapport with your SA. They won't give it outside, but you can have it!

There are several specs, which a newbie technician will overlook. I am sure Mahindra may do a better job than other brands, but still as an owner of the ride, we do have an OCD to keep our ride the best and in shape as day1. Example- The clearence of a valve/ manifold will be given as certain mm ..even if it off it won't pose a harm instantly, but it can affect other parts.

Frustrating AdrenoX experience (continued)

Finally I was able to time and capture the AdrenoX ‘Silver Box’ reboot sequence which happens every 5 minutes post the last reboot.

Till the ‘Disclaimer’ screen is visible, pressing the camera button activates the camera. After that, nothing works and a count-down for 5 minutes starts internally repeating the reboot cycle over and over again. Hill Hold Control Error also appears out of the blue.

Without the Center Screen, there is no way to play Music, no Radio, no phone connection even for basic calling let alone Android Auto / Carplay, no Camera, no navigation, no way to change the Drive Modes and no way of knowing the Fan speed or the temperature set.

Upon reaching out to Mahindra, it became clear that this is not a software fix which resulted in ordering of the ‘Silver Box’ for it’s replacement. Surprisingly the remote features of the currently installed unit had been disabled upon ordering of the part itself with today / tomorrow being the clarity for part arrival.

It must be frustrating to get these type of defects plus it's dangerous as well.
Indeed, the instrument cluster reboot is pain on long drive (more so when you know the area has speed cams) and the lack of functioning cameras becomes really frustrating while reversing & parking. Stories and delays from Mahindra only act like salt.

Fantastic review of the XUV700! It provides a lot of insight with regards to ownership. It is quite saddening to see the glitches that you are facing. I guess only saving grace (at times) is that Mahindra is reactive. TATA experience could have been worse!

The ‘Silver Box’ replacement

Despite the dealer procuring the part from a near-by dealer which should have been an overnight delivery, somehow it took them 2 days to arrange the same.

The actual process of removing the glovebox, removing the old unit and reversing the sequence with the new unit hardly took any time – probably 45-60 minutes for the entire mechanical swap. What took most of the time though was availability of the right person both at the dealership for sharing the relevant details back to Mahindra and then at Mahindra to finally approve the release of vehicle – the whole process dragged the timeline from an hour to 4 hours. Thankfully it was less than the requested entire day for replacement.

Couple of learnings from this:
  1. An year into sales and Mahindra has still not perfected the software end. Glad the ECU is not integrated in the ‘Silver Box’ and the vehicle was still driveable with something as basic as instrument cluster failing and with features less than even my humble Genio.
  2. The ‘Silver Box’ failure is quite common post the Apple CarPlay update and the same is not recommended anymore – that’s the story I got and I was happy to live without the CarPlay update. Surprising that the part is not readily stocked if that is the case.
  3. The information sharing process between dealer and Mahindra which consumed a good chunk of time could have been saved in my opinion.
  4. Cut one head and two more shall Rise. While the ‘Silver Box’ replacement solves an issue, it opens up a Pandora box with firstly the exterior having bird poop at multiple places & the interior panels (luckily plastic only) getting finger prints and smudge marks and secondly the front passenger area getting a faint squeak.
  5. Washing & Cleaning mentioned on the RO is only a gimmick and the job won’t be performed. When questioned the response was that’s it mentioned by default on the RO. Not sure why it was part of approval as well at the time of RO opening which showed zero amount.
  6. It was surprising to see a pending payment for the disposable covers on a warranty part replacement visit which not there on the same RO when the diagnosis was done 3 days prior. While it was waived off as a goodwill gesture, it should not have been there in the first place.
While setting-up the new system, found some interesting notifications.

While it’s a nice touch, not sure from where Mahindra picked up this date as it’s incorrect.

A word about the not so latest 8.01.41 version:
  1. Happy to report that Android Auto connection so far has been seamless with the connection happening automatically everytime.
  2. The Instrument cluster now display the maps without setting a destination – that’s the way it should work ideally.
  3. Camera seems to have higher frame rate now.
  4. Not sure if it was present earlier or not but yesterday I accidentally clicked on the XUV7OO icon displayed on the top view which enabled some transparent mode. While this works only at low speeds, it looks cool to see what you have just passed over under the translucent XUV7OO icon. Only in this mode and the 3D mode the frame rate drop is observed.

ADAS issue and getting the Sequential Tail Lamps

While cruising along on the highway, out of the blue the Adaptive Cruise Control got disabled, a warning chime sounded and when I looked at the cluster, the error below came-up.

I tried to clean the windshield multiple times with the washer wiper (both while stationary and while moving) but the error didn’t go away. Recorded this video

Restart as well didn’t solve the issue and only after cleaning the windshield manually did the error go away shortly after starting to drive. I suspect that the Passenger side wiper itself is not cleaning the entire area and is lifting-off at the top near the ADAS camera due to the curvature of the windshield.

Closer pic from top of the area cleaned by wiper

This error occurred only twice till now and the only solution is manual cleaning of the windshield.

Recently also noticed that one of the Rear Door Chrome strip has finishing issue with the metal part coming off.

Most likely would be replaced under warranty.

Got the much awaited Sequential Tail Lamps as well but it was not without it’s share of story. After opening all the Tail gate inner trim and removing all the lamps to save time while the parts were being issued from stores, it was found that one side outer and other side inner lamp had transit damage. And they were the only available parts that day with fresh lot expected to arrive the next day. Got just the lamps fixed back and carried the trim panels in the boot to avoid fitment and removal the next day.

The dealer promptly informed the next day that the parts had arrived and were already opened and checked for quality before calling me. It hardly took 30 minutes to swap the lamps and I took the opportunity for getting the only 2 bulbs (Brake & Reverse) changed to LED.

1st Service of 10000 Kms

Due to unplanned travel which came-up for next day and the odo already at 9500 Kms, checked with the local dealer Mighty Mahindra if they could accommodate the request for 10K service an hour later at 3pm. They were kind enough to accommodate the request and had a blazingly fast turn around of just 2 hours which included some minor jobs.

Engine Cover was rattling and it was fixed properly. Tyre rotation with steering calibration addressed the issue of steering feel which was different since the Lower Control Arms replacement. Engine Oil, Oil filter and cabin air filter were replaced while cleaning the Engine air filter. 6 Liters of DEF was also added bring the total service cost to Rs. 4,471/-. Including the previous DEF top-up of 8 Liters (Rs. 977 including filling charge), the total DEF consumed was 14 Liters (Rs. 1631 total expense) for 9500 Kms leading to approx. an average consumption of 680 Km/L and additional cost of Rs. 0.17/Km.

Oil used - surprisingly the grade is not mentioned on the Oil

DEF is also specially packed for Mahindra

The next day left home early for the destination but upon crossing the 9800 Kms mark, the alert for scheduled service due came-up.

Tried to search for options through the settings but couldn’t find any and finally waited till 9AM before calling the CoTek for help. He promptly guided on the process to reset this by Switching OFF the ignition and then Switching it back ON without pressing the brake pedal but keeping the Enter button on the steering pressed and releasing it just before the needles complete their sweep. Post this, the alert got cleared and it didn’t come-up again.

Post lunch after the restart suddenly the look and feel of Android Auto changed to coolwalk which was a pleasant surprise with the maps using the entire screen real-estate.

Some observations after covering 10K Kms:

1. Till now I have had 05 additional visits (once for Navigation issue, Silver Box replacement diagnosis, Silver Box replacement and twice for Tail Lamp replacement).
2. The only persistent noise bothering as of now is from DEF / fuel tank.
3. Drive normally and this engine rewards with exceptional FE and whenever you need that extra power, it delivers without hesitation.
4. Though ADAS is over cautious at times with some random braking, once you adapt to it the drive is quite blissful especially on the expressways.
5. Last couple of weeks saw quite a lot of issues with AdrenoX app (remote commands activation getting stuck, random log-out from app, trip history not working, live location sharing not working etc.).

Why can't they be always more cautious while installing fitments.[frustration]
That's there but I feel it's more to do with the Plastic composite tailgate and in my opinion the dimple in the paint visible in the Driver side pic would not have been there on a metal surface.

Experience from covering 3500 Kms in just 10 days

Certain circumstances required taking 2 round-trips of around 1400 Kms each split equally over 2 consecutive days just 8 days apart. Including some work related travel, it meant covering a colossal 3500 Kms in just 10 days post service.

An interesting behavior I noticed on my highway trips is once the speed stabilizes to anything above 60-70 Kmph after starting from even 2-3 days of pure city run covering 100 Kms at max, there is a considerable drop in FE (as noticed via the instantaneous gauge) for the first 20-25 minutes. Post this only normalcy is restored and the FE jumps back up by 2-3 Kmpl. Looks like automated DPF regeneration happening in the background to clear all the soot accumulated from the city runs. Wish the Information skin on the instrument cluster gave some real information related to what’s happening with maybe some advanced gauges for Soot level & regen state, Turbo Boost, Battery Voltage, Transmission Oil temp., etc. With the Android based implementation, would have been great to just have Torque Pro installable on the center screen for all this information and more.

It is worth pointing out that a decade ago this same travel used to take in excess of 12 hours with 2 proper breaks for meal & snacks and other short ones for nature’s call. The Agra-Lucknow Expressway reduced the time by almost 1.5 hours and finally the Meerut-Delhi Expressway and Bundelkhand Expressway reduced it by another 2 hours with the journey now taking slightly over 8 hours with just one meal break among other short ones.

Once again the Adaptive Cruise and Smart Pilot assist worked flawlessly on the expressways and after having got used to the quirks they make driving a real bliss. Noticed that the truck traffic on the Bundelkhand Expressway has increased many folds (probably due to no toll yet) and it was alarming to find repairs have already started on this newly opened expressway.

Just 8 days later travelled on the same route once again, only the timing was different involving more of night driving on the return leg. The Booster lamps really aid in driving and give the confidence at night.

All thanks to the night travel, the Bugs had left there mark in a bigger way this time and required cleaning the windshield manually as well twice during stops. Currently using the WaveX windshield washer concentrate but need to find a better solution which is effective on bugs.
