Vehicle2008 Nissan Altima Hybrid 4dr Sedan (2.5L 4cyl gas/electric hybrid CVT)
ReviewFor Nissan Altima Hybrid owners the carbon buildup is about to hit the fan, or not, which is the problem. Be ready to spend at least $4,500 to replace the cylinder head in your car. My 2008 Nissan Altima Hybrid needs a cylinder head replacement at a minimal cost of $4,500.
Carbon buildup due to improper discharge is the cause. It's a design/manufacture defect known to Nissan for years and theyve acknowledged in an internal bulletin that it is occurring in at least 1 in 4 Nissan Altima Hybrids. My Altima is within the five-year warranty period, but has 64,000 miles on it so falls just outside warranty.
They won't honor the warranty and won't recall.
Bad company - Bad car.
Best FeaturesI can't point out any favorite features when my 2008 Nissan Altima Hybrid runs so rough it feels constantly like it is going to stall. Nissan wants me to pay them $4,500 to fix a problem they created by putting springs in the cylinder head that are too strong. Literally, highway robbery.
Worst FeaturesNissan Motor Company could take more responsibility for their manufacturing and design flaws, like Toyota does, rather than trying to hide them. This is a company that is not to be trusted.

We have 2007 Nissan Altima Hybrid has the same problem. It has 25243 miles on the car, but it is over 5 yrs(5 yrs + 9 mon.). The cylinder head (valves) has to replace & it was in the Dealer for a week. Nissan is not willing to pay the warrenty repair Nissan only pays materials cost. We have to pay all labor ($2888). It is the design problem for the Hybrid which is for city street driving for saving gas, but the poor engine design causes Carbon build up around valves(in cylinder head). Nissan should pay the repair warrenty. Nissan should send warnings to user(s) to drive in high way ratio between city street driving vs highway driving to prevent carbon build up in valves(engine). Nissan Hybrid is bad car for city driving.Report it

I had the same thing happen on my 2009 Altima Hybrid although I made it to 117,000 miles. $3600 to repair, the dealer basically said it's inevitable that the carbon will build up over time. So they have a design that is known to require a head replacement at some point.Report it
