2000 Nissan Altima — Known Issues & Recalls

While driving at 40 mph, your temperature gauge climbed near maximum and the engine began running roughly with smoke entering the cabin. A mechanic found the engine had no coolant and was not the original equipment, which caused severe overheating and a cracked engine block. The damage was severe enough that the vehicle was not repaired. Fixing this will require a complete engine replacement or major engine block repair and a full cooling system refill.

Your check engine light came on while driving home, and your engine started running rough and shaking. The diagnostic codes indicated a knock sensor issue and a cylinder 4 misfire. The problem developed suddenly without warning, progressing from a rough idle to severe shaking in just 200 yards. Resolving this will likely require diagnosing the knock sensor and ignition system, and possibly replacing spark plugs or addressing cylinder 4 fuel delivery.

Your engine idles roughly and shakes, particularly due to cylinder 4 misfiring. A mechanic diagnosed this as a faulty intake manifold gasket and quoted $1,500 to replace it. You've noticed similar complaints from other 1998-2001 Altima owners, suggesting this may be a widespread issue. Fixing this will involve replacing the intake manifold gasket to restore proper engine combustion and smooth idling.

Your instrument cluster—including the speedometer, tachometer, odometer, and temperature gauge—freezes intermittently and stops updating for extended periods. Because the temperature gauge wasn't working properly, you couldn't tell your engine was overheating, which led to water pump failure, a blown radiator, and engine damage. The fix will likely involve diagnosing the instrument cluster circuit board or wiring, and potentially replacing the water pump and radiator.

Your check engine light came on while driving at 45 mph. The dealer diagnosed a failed catalytic converter that needs replacement. The manufacturer was contacted but the vehicle was not repaired under warranty.

Your engine stalled without warning while you were driving at 2 mph, then restarted on its own. This happened once at 95,000 miles, but you didn't have it diagnosed or repaired. The stalling could be caused by a fuel system issue, ignition problem, or engine sensor malfunction.

Shortly after starting a long drive, your cruise control stopped working and the airbag warning light came on. When you tried to accelerate, the car slowed down instead, leaving you unable to control your speed. Another vehicle hit you from behind, causing a crash that resulted in serious injuries to you and your passenger.

Your instrument panel gauges (speedometer, fuel gauge, etc.) stop working on and off. When the gauges do work, your car loses power unexpectedly. The problem was repaired once but came back. The issue started around 130,000 miles and continued through 150,000 miles. A mechanic will likely need to diagnose and repair the electrical connections or components in the instrument cluster.

Your dashboard randomly goes completely dark, making it impossible to see your speed, RPM, or fuel level. When this happens, your engine sometimes loses power as if the gas pedal isn't responding, then suddenly surges forward without warning. This happens frequently and creates a serious safety risk — you can't control your speed, and the sudden power changes could cause you to be rear-ended or crash into traffic ahead. The issue also triggers false check engine light codes that mechanics can't properly diagnose.

While driving at 75 mph with cruise control engaged, your dashboard gauges (RPM, speed, fuel level, and engine temperature) suddenly dropped to zero, and random numbers and letters appeared on the odometer display. When you turned off the cruise control using the steering wheel buttons, all the gauges and odometer returned to normal. This electrical glitch may be caused by a faulty cruise control switch, instrument cluster wiring issue, or a malfunctioning dashboard circuit.

While driving at 40 mph, both your driver and passenger airbags suddenly deployed without any warning or impact. The driver's airbag hit you in the face, causing you to lose control and crash into a curb, which damaged your transmission and passenger seat belt. You had noticed the airbag warning light flickering on and off before this happened.

Your steering wheel locks up when your car reaches around 84,000 miles, making it impossible to steer. This is a known problem affecting many vehicles, but the recall has expired. The Nissan dealer quoted $1,050 to replace the faulty steering lock actuator, and many owners report this happening repeatedly.

You were hit from behind while stopped at a traffic light, which caused you to hit the car in front of you. Your airbag did not deploy during the crash, and you suffered serious injuries including a head injury and broken spine. Your vehicle was severely damaged. You also report that your 2005 Nissan Murano has an airbag warning light that is on and flashing, making the vehicle unsafe to drive. Fixing this will require a dealer to diagnose why the airbag system failed to deploy and repair or replace the airbag control module and related sensors.

You were driving and didn't notice a stalled vehicle ahead until it was too late, resulting in a crash. During the collision, your airbag failed to deploy, and you struck the steering wheel with significant force, causing chest, neck, arm, and jaw injuries along with breathing difficulties. The airbag system may need inspection to determine why it didn't activate during the impact.

Your brake pedal went all the way to the floor and your brakes stopped working. The problem was that spot welds on the bracket that attaches the brake hose to the strut assembly failed, causing the bracket to separate. Once the brake hose came loose, it got punctured by moving parts underneath the car, causing you to lose brake fluid and brake function. The fix will likely involve replacing the brake hose and reinforcing or rewelding the bracket that holds it to the strut.

Your car's front end has been making strange noises, and a Nissan dealer discovered that the left front strut tower is separating from the vehicle frame, making it unsafe to drive. You've also noticed the right side strut tower is cracking and rusting. The dealer indicated this requires body shop repair rather than standard maintenance.

Your car's front subframe has severely corroded and broken away from the suspension, causing excessive movement in the front end. The subframe has perforations and weakening throughout, which was confirmed by both an independent shop and a Nissan dealership. Nissan refused to cover the $2,300+ repair cost, claiming lack of owner maintenance was responsible, though there is no recommended maintenance for subframes according to Nissan documentation. The repair will likely involve replacing or reinforcing the corroded subframe and related suspension components.

Your car is stalling and shutting off while you're driving. This is likely caused by a fuel pump problem that's interrupting the flow of gas to your engine. Having this checked and repaired is important for safety, as sudden stalling can create a dangerous situation on the road. The fix will probably involve inspecting or replacing the fuel pump.

Your dashboard gauges (speedometer, fuel, temperature, and others) frequently shut off, freeze, or jump around while you're driving, making it difficult to know your speed, fuel level, and engine temperature. This problem has been happening since you purchased the car and occurs intermittently—sometimes the gauges work fine, but most of the time they're not functioning. The issue likely involves repairing or replacing the instrument cluster wiring, connectors, or the gauge cluster itself.

Your fuel gauge isn't showing accurate fuel levels. It initially showed 1/4 tank when you actually ran out of gas on the interstate, and since then it consistently reads lower than your actual fuel level—for example, showing 3/4 full when you've filled up completely. This can be dangerous if you rely on the gauge and run out of gas far from a gas station. The fix will likely involve replacing the fuel level sender unit or fuel gauge sensor in your fuel tank.
