Recalls
4 recalls name the 1991 Porsche 911. Newest first.
A part of the steering column upper universal joint cracked during the manufacturing process.
Risk and remedy
Risk
This condition could result in noise and free play in the steering system and if left uncorrected, will result in loss of steering control.
Remedy
Dealers will inspect the universal joint for cracks and will replace cracked joints with new parts.
After the engine has been turned off, the rear heater will automatically operate in order to dissipate heat in the engine heating system. During this operation, the resistor for the rear heater blower can become overloaded due to a binding or seized rear heater blower.
Risk and remedy
Risk
The overloaded resistor can create heat sufficient toignite the plastic air pipe to which it IS connected, resulting in an enginecompartment fire.
Remedy
Porsche dealers will install a new resistor containing a circuit breaker.
The hydraulic brake pressure reduction valve causes the rate of hydraulic pressure reduction to slow down, which may result in the rear wheels locking-up even with the anti-lock brake system in operation.
Risk and remedy
Risk
Rear wheel lock-up may result in loss of vehiclecontrol and an accident.
Remedy
Porsche dealers will install a modified hydraulic brake pressure reduction valve.
The ball sockets on the cruise control linkage can break, allowing the cruise control linkage to become detached on one end and jam on nearby components, which could impair throttle plate operation.
Risk and remedy
Risk
Impaired throttle plate operation could prevent theengine from returning to idle, resulting in unwanted engine speed and possiblevehicle accident.
Remedy
Replace the current plastic ball sockets with a new linkage using steel ball sockets, and lubricate the cruise control relay lever. Owners are advised not to use the cruise control until the modification IS installed.

On 4/18/2021 I was driving my 1991 porsche C2 on the 10 freeway in monterey park, ca when suddenly I heard a loud bang sound from the engine. I got off the freeway and stopped and found that the entire engine cooling fan had completely sheared off and broke apart along with the fan belts. Less than 5 years ago the same engine cooling fan had to be replaced because it broke apart. This fan also broke apart about 20 years ago! The current incident caused damage to the alternator and air conditioner compressor and the belts and small dents to the back lid.
