1998 Z28: Have experienced fuel pump failure (replaced by dealer circa June 99) also, experiencing an erratic fuel gage...reading fuel for a lengthy period of time, then suddenly drops to less than 2/3. intermittent horn function: Complete horn failure; however, if you shut the engine off and restart horn will work. Front rotor warping repeatedly. Manufacture denies there is a problem, says driver is overheating brakes. I believe the problem is rotors are poorly designed. Also found if you don't drive through water when rotors are hot that this will help. Slow acceleration after cold startup. However, if you shut engine down and restart acceleration will be normal.

Front brake rotors warped on 1998 Chevrolet Camaro Z28; I know of several people personally that have 1998 and up Camaros/firebirds that had this issue. I have also heard many similar complaints from people in car clubs and internet message boards. People refer to the stock rotors as junk because they warp so often which leads me to the conclusion that the car manufacture did not put adequately designed rotors on the vehicles. People with this issue say to buy non-oem rotors because they will warp again and simply having the rotors turned does not help as they warp again. I have actually had my rotors turned and new brakes (installed by dealership with oem parts) put on the car and I have the warping issue. Mechanics that I know also agree that the brakes/rotors are not adequately designed for these vehicles.

Freeway speed braking compromised due to extreme vibration caused by warped front rotors. Dealer has tried to repair problem by machining - always reappears after 5000 miles. Now they refuse to fix as it is a 'wear item'. this is a design or material quality issue that has been present since new. Brakes that can't be used to their full effectiveness are a safety item.
