Differential Unit problems of the 2013 Honda CR-V

Especially when cold under light acceleration, the vehicle will shudder. I think it is when it shifts from 1st to 2nd gear. Took it to the dealer for normal service and asked them to check this issue. Went to pick it up and was told they confirmed the issue. They told me the issue was reported in later models and a possible fix was to change the transmission and rear differential fluid and update the software. It would not be covered by the Honda 5 year/60k mile powertrain warranty or the extended warranty purchased when we bought the car new. I was charged $88. 00 just for them to confirm the issue and also Honda was aware of the issue. Since they said it would only possibly fix the car at a cost to me of around $300. 00 and there were no fault codes, I opted to forego the procedure. After I got home I found numerous reports of this problem on user forums. I also found a link to print the Honda service bulletin sb 15-086, dated August 18, 2016. That was stated for crv model years 2012-14. Hopefully the problem will not result in a catastrophic failure, causing injury or damage. Honda evidently does not believe it could or there would be a recall.

I started to notice a croaking (sounds like a frog) noise coming from the rear of the vehicle when lightly accelerating from a stop in drive or reverse and right before I come to a complete stop. I have had this vehicle for a year, which I purchased new and this sound started after 11 months of ownership. I took my vehicle to the dealership where it was determined that the noise is coming from a noisy rear differential pump motor (part of the awd system) per a manufacturers tech line summary article. Per the dealership and manufacturer, the manufacturer is aware of this problem and is currently working on a fix, but does not have one to date. Manufacturer has instructed dealerships not to replace any rear differential pump motors at this time.

I purchased a 2013 crv in the beginning of 2013 with VIN # [xxx]. With about 6,000 miles after the first oil change, the vehicle starts making a creaking noise when pushing and releasing the brake. I went to the dealer on 11/11/13. A technician was able to duplicate the problem. The second visit to the dealer is on 11/25/2013. A master technician was able to duplicate the problem and identify the noise does not come from the braking system but from the rear differential system. The dealer made a phone call to Honda tech line and was told to hold on the fix and wait for Honda to do more investigation. The dealer said Honda will send me a letter in the near future. I waited for the response from both dealer and Honda for more than a month and heard nothing. The dealer told me to contact Honda directly. I called Honda in end of December 2013, and heard back from them in 1/3/2014, a Honda representative named [xxx] in 1-800-999-1009 [xxx] called me back and told me that Honda is not going to fix the problem and replace any parts but will do more investigation. He mentioned that the investigation will last for 2 to 3 years. Also Honda is not considering the rear differential system is failed or defective, because the computer did not notify them such part is failed. [xxx] refused to give me more information and did not want to issue a statement or letter to me to describe the problem and what further investigation will Honda do. [xxx] keeps saying that he is not an engineer to answer any technical related questions. The decision made by Honda is no repairing or replacement to any part to fix this problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Just before coming to a full stop or accelerating from a stop a grinding noise coming from the rear of the all wheel drive vehicle. Dealer identified problem and is to replace the rear differential.
