My brother?s montero was fixed by the dealer for this issue, but the same day the issue return now the dealer said they need to replace the whole part more of a $1,000 just in parts it? s what they couted. Could it be that the brake booster accumulator that the dealer install it?s defective???
Any comment would be very helpful
