2020 Honda CRV EX: From an Oil Change to a Flat Tire to Replace the Radar?
Looking for any experience, insight and to share info re: the following problem.
In 50+ years and millions of miles of driving, I have never experienced a flat tire leading to the repairs recommended below.
The issue stems from Honda Diagnostic Trouble Code (DTC) B2A00-92 "Temporary Stop of Integrated Drive Support System" which continues to be generated from the on-board monitoring systems.
Vehicle: 2020 CRV with approx. 56,000 miles.
Ownership Experience: Prior to subject problem, EXCELLENT.
Location: Germane to the facts listed below, we live in a beach town in coastal South Carolina. Most of our shopping, medical and service needs require a 40–50-mile one-way trip to Charleston, SC. This includes the Honda dealership, AAA center and Costco noted nelow.
1. In preparation for two planned trips, on May 2 the vehicle was taken to a Honda dealership in Charleston for routine oil change. At the completion of the work recommendations were provided to: change a couple filters, replace transmission fluid and complete a four-wheel alignment. No issue was noted as critical.
2. The day following the oil change subject, while being driven to Charleston for errands, the CRV experienced a punctured tire. My wife was able to bring it to an air pump at a service station, fill the tire with air and drive it to our AAA center where the limited-service spare was mounted. The tire was part of a set purchased from Costco so the vehicle was taken there. A new Michelin Defender tire was ordered: I drove the car home and placed it out of service until delivery of the tire.
3. On May 10th Costco mounted the new tire on the existing wheel and installed on the CRV. The tire was covered under their Road Hazard Warranty so adjusted cost to us was ~$45.
4. On delivery of the vehicle with the new tire, 14 warning codes were experienced shortly on commencement of driving. Costco recommended taking the car to the Honda dealership for reset.
5. The Honda dealership service department reset the code monitoring system. While returning home, three returned (ACC, Road Departure, Collision Mitigation) within 25 minutes of the start of driving.
6. I made an appointment to return to Honda however, schedule conflicts prevented return until May 15th. While waiting for appointment, I drove the care and noted the following.........Through the initial 24-25 minutes of driving handling was normal and all controls worked. No warning lights activated. Typically, however at around 24 minutes, the three alarms noted in #5 above activated. I varied driving conditions, speed particularly. Warnings activated in 17 minutes in one instance, but on most occasions, warnings activated at approximately 24 minutes. NOTE: With or without activated warnings car handling was normal. Also, the warnings reset by bringing the vehicle to a stop and placing in PARK for a few seconds.
6. On May 15th the Honda dealer again reset system. The techs discovered that Honda Diagnostic Trouble Code (DTC) B2A00-92 "Temporary Stop of Integrated Drive Support System" was being generated and they were able to reset the system to silence. The car was driven following the reset for several hours (off and on) eventually the warning signals returned.
7. On May 22nd, I sent a letter to dealership management regarding the problem. The head of service contacted me and arranged for us to return with the car which we did on Wednesday May 24th. After diagnostics, road testing, etc. the initial service recommendation is to replace the car's radar unit and do a four-wheel alignment, cost estimate approx. $1100. The car remains at the dealership.
Just can't see how one goes from a flat tire to replacement of a portion of the vehicle's control systems.
Any thoughts, similar experience, etc. that you can share are welcome.

Yep, weak battery, I suspect, especially if your CRV is driving fine.
someone needs a new battery .
You possibly need an alignment if tire wear was uneven or if the car was driven around on a flat tire. If the car was showing a mileage minder code for filter and transmission fluid replacement, this should be done. You can easily monitor these codes yourself to see what is needed.
Multiple warning lights as you described are often a sign of a weak battery. The 2020 model has the larger battery on account of the start/stop feature but if you or a previous owner only have been taking short trips, or have had lots of down time between trips, you need to use a battery maintainer or the battery will need an early replacement. Lots of info on this forum through the search function about batteries, multiple warning lights etc.

Thanks for the info; rookie mistake on the long post.
I have the battery and alignment as next steps to do.
Turns out the swap out of the radar came from the tech group in California based on limited data. We are not “going there”.
Will report back on progress.

Unless there is less than 50 miles on the tire - all vehicles with TPMS that use the ABS to detect tire pressure loss require that they be replaced in pairs.
All CR-V's use the ABS rotation difference to se the TPMS.
You get a lot of warning when the tires are just a little difference in size. It freaks out the computers.

If the only warnings you're are seeing now are ACC, Road Departure, Collision Mitigation, I have doubts it's the radar. I would suspect the camera. Reason being "Road Departure" is not affected by the radar. Radar is used for ACC and Collision Mitigation. The camera is used for ACC, Collision Mitigation, LKAS, Road Departure and Auto Headlight Dimming. If you had Auto headlight dimming and LKAS turned on, I would expect those alarms to also show up if there was a camera issue. Regrettably the camera processor is bad about not storing faults when they occur. You basically have to pull the error codes when they are occuring before you shut off the car. My suggestion is when you get the alarms, do not turn off the car. Instead drive to the dealship. Leave the car running with the alarms active and grab the service tech to check it. I had this same issue and when the alarms went off took it to the dealer. With the alarms active the tech had no problem seeing the camera was at fault.

What matters is: are all the tires the same brand and model tire, AND what level of tread is left on each tire. As long as the tread difference is 3/32 or less... there should be no issue with replacing only the single tire. Even then, they can shave the tread on the new tire to bring it within 3/32, which is cheaper than buying a second new tire.
It is the tire model and brand that matters most, which is why you NEVER install a replacement tire that is a different brand/model as the other 3 tires.
You appear to be experiencing multiple unrelated issues, so the first suspect is definitely the 12 volt battery first and foremost.Looking for any experience, insight and to share info re: the following problem.

If there is something wrong with the new tire working cooperatively with the other 3 tires, due to tread difference or a defect in the tire, that will disrupt the wheel monitoring and drive control systems which could pop a light show on your instrument panel. It sounds like Costco replaced the same make/model tire, so that should not be the cause. "Temporary stop of integrated drive support system" is a flag here in my view. As to cause and correction ... dealer will have to figure that out.
Personally, I cannot see how the front radar assembly can trigger the code the dealer reported, but I don't any of us know absolutely all the interlinking of various driver assist systems in modern CRVs. Modern Hondas tend to over-present error messages on the driver instrument panel. Example: a wheel rotation sensor, a key component in modern CRVs can sometimes go bad and will trigger all kinds of driver assist error lights... so a big light show does not always mean big things are broken. I would pause on replacing the radar until you have had other causes ruled out... mainly due to the cost of the unit and the fact they are probably on long lead time back order anyway since they have become a target for thieves of late.
Personally, I have never seen a tire shaved or know who does it, they may be out there doing it, but I'm just not sure if I would do something like that.

With Tire Shaving, a Flat on an AWD Car No Longer Means Replacing All Four Tires - Consumer Reports
Conventional wisdom is that when you need to replace a single tire on an all-wheel-drive vehicle, every tire should be replaced. Consumer Reports says tire shaving provides a more affordable option.
Makes sense for sure, don't think Costco or most have this, maybe a specialty device, I'll ask my tire shop next time.
Thanks to everyone for your great comments; terrific testimony to this site and the commitment of our fellow CRV enthusiasts.
The battery has been tested to be within specs as was the alignment.
I am going to pick-up the car this afternoon to see if the dealer's work has solved the problems. They have tried using different tires but landed back on my original set of Michelin Defenders. The newer of the tires has a 3/32" variance to the other three which, given all the variable of driving (temperature, road conditions, etc.) would not seem to be significant.
In the course of their work, the dealer's techs have conducted a "hard" reset of monitoring system, which I assume clears out any transient data in memory. Will see if that works; if not, based on the discussions here, I will pursue first battery replacement followed by replacement of the other rear tire.
Will report back on progress.

Yeah, you have to go to a specialty tire store for that. Costco would not have the equipment for this.Makes sense for sure, don't think Costco or most have this, maybe a specialty device, I'll ask my tire shop next time.
I've never had to do so, as the only time I have had to replace a tire that died early due to road hazard, the tires on the vehicle were nearly new, so the new tire was well within the 3/32 rule. I did have to have the shop order the exact same tire from their warehouse to have exact same brand/model/size tire.
FYI - A few months ago, one of the rear tires on our 2022 Hybrid CR-V had an "encounter" with a drill bit (must have fallen from someone's work truck). There were 20K miles on the tires at the time. The hole left by the drill bit was too big to patch or plug so I replaced both rear tires (so they matched on the same axle). Though they are different brand and diameter from the front, I have had no alerts.Inaccurate.

Probably no problem as long as you always rotate the pair, exchanging with the front pair. So stick to front to back rotation and avoid diagonal front-rear which some tires now support. Just be explicit with service providers when rotating tires.FYI - A few months ago, one of the rear tires on our 2022 Hybrid CR-V had an "encounter" with a drill bit (must have fallen from someone's work truck).
