Noise when driving uphill or accelerating
My 2012 Hyundai Sonata GLS started making noises about a month back.
The noises always happen when driving uphill and sometimes happen when simply accelerating.
The noises almost sound like the engine revving but the RPM does not seem to be increasing out of normal range.
Ist dies eine gute Frage?
Is it an auto? Could be slipping. If a manual, same thing, but you would also notice that the car seemed to lag when going up hill.
