Honda S2000 Problems
A problem can occur with a vibrating expansion valve in the AC system which causes a whistling noise from the passengers vent. Replacing the expansion valve with an updated valve from Honda should repair this problem.
Some S2000's can develop a problem with the transmission popping out of fourth gear. A new updated fourth and fifth gear assembly will repair the problem. The transmission will have to be removed and disassembled for this repair.
The S2000 is set up with aggressive alignment settings and soft tire compounds to enhance handling. These alignment settings and soft tire compounds result in tires wearing out earlier than anticipated. This is a compromise made to have a car with exceptional handling characteristics.
The MAP sensor contacts can shift at high RPM causing a hesitation. Replacing the MAP sensor will repair the problem.

RepairPal Expert Overview:
The braking system uses an assist device called a brake booster. These vehicles use a brake booster that is operated by engine vacuum and in certain cases the booster may not be able to maintain a vacuum when the brake pedal is depressed. This will result in reduced braking assistance, requiring additional force on the brake pedal to stop the vehicle. Dealers will inspect the brake booster and replace it as necessary.

The car is overheating but I have no heat in the car. The no heat would cause me to think its the thermostat, but it doesn't explain why It's over heating?

Honda S2000 Reviews
Truly an awesome car. its at its simplest form of a convertible sports car. its nimble, quick, reliable and is good looking. Lowered it with 9 inch wide wheels.
2008 Honda S2000 CR
Rear tires pretty much go every 10,000 miles even when driving calmly the whole time. The exhaust is not loud at all; in fact, under heavy acceleration, the driver notices engine noise more than exhaust note. The 6-speed manual transmission has to be the greatest shifter put in a production car, south of supercar territory. The cupholders are pretty much useless. I just used them to hold my spare change!
The airconditioner makes weird whistling noises from the passenger side; the trunk is small but relatively big compared to its competitors, such as the Pontiac Solstice or Saturn Sky; the S2000 CR comes with factory tools but no spare tire; the suspension is improved, and if driving a CR and then a base S2000 back-to-back on a track, the driver will definitely have more fun in the CR.
The car could use a bit more power. There are econobox cars, such as the Toyota Camry LE, which can keep up with the S2K on straightlines (not condoning street racing, just making an observation). The factory sound system is rubbish, especially when cruising with the top off. Note: CR comes with removable hardtop, not softop.
Another thing that is a common annoyance with many S2000s is that the car will tell you that the key is still in the ignition even if it isn't when you remove the key to get out of the car. It just continues to make the chiming noise.
I've owned 2 S2000s in the past 3 years. One was a 2007 new formula red; currently own an '08 apex blue pearl CR. The car has its faults just like any other car; however, in the end none of that matters when driving the CR on an open road, enjoying the 100% driver involvement (if you can't drive stick, forget about it!), or just taking it to the track and ripping past cars that cost twice the MSRP of the S! If you buy it, you'll enjoy it. I've daily driven both the S2000s I've owned (traded '07 for '08) and both performed commuting duties flawlessly.
Ours has 18,000 miles. Rear tires will need replacing within the next 5000 miles, or less. On cold days with top down, there is a special heater blower setting to keep the passengers toasty. An excellent car. Cup holders don't hold the cup. It can fall over, literally, when you accelerate. Also, two cups don't fit unless they are very, very slim. Other than that, it cannot be improved. I couldn't hear the engine which made driving by "sound" impossible. So, I had the resonator removed. Gave it a little more "tune" which is just right. This fix was recommended by many other owners who had the same concern.
This is one of the best cars I have ever owned. The top is easy to use and keeps the weather out which is great, better than some of the older convertibles I have had. The motor is lacking in the torque department but once you hit the 6k RPM mark, everything comes to life. Car handles well, except at the limit, it tends to snap out without warning, but other than that I would buy another one...if they still made them.
I've had my s2000 for about two years. The only problem that I've had is with the rear tires wearing out. I took a road trip and this car and had a wonderfully time driving it. Accelaration is outstanding except for the first two gears. I was caught in a very sever thunderstorm and it went through it like butter. GREAT CAR!
