One problem related to manifold/header/muffler/tail pipe has been reported for the 2010 Honda CR-V. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Honda CR-V based on all problems reported for the 2010 CR-V.
The first time we became aware of any issue was around 3/3/16 (64224mi) when we started hearing engine/muffler noise and we mentioned it when we brought car in for airbag replacement. By 7/21/16 (67233mi) we were hearing very strong motor noises and the car began to drive very rough. When we took it in they advised us we were 3qts low. From the last oil change at 60742mi that amounts to 1. 0qt/2164mi. They told us we needed to do an oil consumption test. On 8/10/16 (67942mi) we were already 1qt low after only 500mi and they asked us to do an oil change when we were only at 40% according to the "oil life" indicator. By 12/2/16 when we finished the oil consumption test and they took several weeks to get back with us, they said our oil consumption was "within normal limits" according to the factory. On 1/9/17 (73743mi) we requested Honda check our oil and sure enough it was down 1. 8qts after 2790mi. That's 1. 0qts/1500mi. They suggested we do another oil consumption test. Clearly, Honda has set convenient "normal limits" in order to delay repairs that could mitigate future engine issues after our warranty (or extended warranty) has expired. We have requested that they fix this problem once and for all so we do not have to be guessing as to when we need to add oil and most importantly because it has most definitely lowered the resale value of our car and made it much harder to sell. The number one reason we purchased this car was for it's high resale value which it can no longer live up to.
