2008 Nissan Sentra — Known Issues & Recalls

Your daughter was in a rear-end collision at 45 mph, and the front airbags did not deploy even though the front end suffered severe damage. No injuries occurred, but the airbag system failed to activate when it should have. The cause hasn't been identified yet, and the dealer wasn't notified at the time of the crash.

Your airbag warning light keeps coming on even after the dealership reset it multiple times. Diagnostic testing shows the airbag itself needs to be replaced at a cost of $1,500, despite your car never being in an accident. This appears to be a recurring issue affecting many Nissan vehicles.

Your airbag warning light on the dashboard stays on and won't turn off. This is a safety concern because the airbag system may not deploy properly in a crash if there's an underlying electrical or sensor problem causing the light to stay illuminated. The fix will likely require diagnostic scanning to identify the fault code and replacing the faulty sensor or airbag module.

Your airbag warning light blinks constantly, indicating a problem with your airbag system. The owner believes this issue may be related to recalls affecting other model years and models of the same vehicle. Getting this diagnosed and repaired is important since airbags are a critical safety feature. A technician will need to scan your airbag system for fault codes and repair or replace any faulty components.

Your airbag warning light is on. A certified dealer identified that a coil component has failed and is causing the warning. This needs to be diagnosed and repaired by a professional to ensure your airbags work properly in a crash. The fix will likely involve replacing the faulty coil in the airbag system.

Your airbag warning light stays on and blinks constantly, and your horn has stopped working. Since both the airbag system and horn are located in your steering wheel, these problems may be connected. A diagnostic scan of your airbag system and inspection of the steering wheel contact module will be needed to identify and fix the underlying issue.

Your dashboard airbag warning light has been blinking for about a month without any recent accidents, and your car horn has stopped working. Since both airbags and the horn are important safety features, you should have this inspected right away. The dealership indicated there are no current recalls, but you'll need a diagnostic inspection to identify the specific electrical or sensor issue causing both problems.

Your air bag warning light is flashing on your dashboard, and your horn has stopped working when you press it. Both of these issues may indicate an electrical problem in your vehicle's safety systems. A mechanic will need to diagnose the root cause using diagnostic equipment and may need to replace components in the air bag or horn electrical circuits.

While driving on the highway with no braking, your master cylinder failed and you lost power-assisted braking. This means your brakes stopped working properly, leaving you unable to stop the car normally.

Your brake master cylinder is leaking, which is causing your brake warning light to come on. This is a serious safety issue because your brakes may not work properly. You should have this repaired immediately by replacing the master cylinder.

Your transmission was replaced under warranty in 2016, but failed again in 2019 after just 40,000 miles. You discovered that Nissan issued a service bulletin in 2014 recommending a transmission cooler be added to prevent overheating on 2007-2012 Sentras, but the dealership did not install it during your warranty repair. Nissan is now refusing to cover the second transmission replacement. The fix would involve installing a transmission cooler and replacing the transmission again.

Your check engine light has come on. A mechanic diagnosed the problem as defective catalytic converter sensors that are no longer working properly. This will likely require replacing the faulty oxygen sensors that monitor your catalytic converter's performance.

While driving your 2008 Nissan Sentra, you heard an abnormal noise coming from the front of the vehicle and it suddenly stopped moving forward. Your transmission appears to have failed, leaving your car unable to drive. The vehicle was towed home but hasn't been repaired yet. Fixing this will likely require a transmission rebuild or replacement, which is a major repair.

While backing out of your driveway, the control arm disconnected from the transmission, causing your axle and ball joint to fail. This damaged the side paneling near your tire and left your car immobile—it wouldn't move even in neutral. Before this happened, you noticed your car would sputter and die when going in reverse, and now it won't reverse at all unless you shift to neutral and let it roll. The issue likely involves replacing the control arm, ball joint, and axle assembly, along with repairing any transmission damage.

After driving for over an hour, your car loses power and struggles to accelerate, forcing you to use a "give and go" driving technique to avoid stalling on the freeway. You've experienced jerking sensations, loss of control, and complete stalling during short drives. Diagnostics have revealed multiple transmission codes and at least one fuel code, but the exact cause remains unclear. This problem started around 60,000 miles and has persisted through 90,000 miles. The fix will likely require a full diagnostic scan to identify whether the issue is transmission-related, fuel system-related, or engine-related, followed by repairs to the faulty component.

Your transmission is experiencing problems, and the dealer quoted you $7,000 for repairs. You believe this should be covered under a recall warranty that extends to 120,000 miles, but the dealer says the warranty has already expired despite your car having only 85,375 miles. You may want to contact Nissan customer service or NHTSA to verify the warranty coverage details for your vehicle.

Your car is driving much slower than normal and won't accelerate properly, even though it worked fine when you first drove it home. This happened just two days after you purchased the vehicle. The issue could be related to your speed control, wheels, or braking system, and you'll want to have a mechanic diagnose whether it's a fuel delivery problem, transmission issue, or brake drag.

Your car is showing a recurring diagnostic code P1778 related to the CVT transmission and an issue labeled IFS that's causing hesitation while driving, especially on the highway. You might feel the car struggling or straining during acceleration. The problem keeps returning even after being addressed. A technician will need to diagnose the CVT transmission system and related sensors to identify and fix the underlying cause.

Your airbag warning light is constantly blinking and won't turn off. Your horn has stopped working multiple times even after being replaced twice, and it stopped working again most recently. Your check engine light also came on while idling, despite keeping up with regular maintenance. These issues likely involve the electrical system and may require diagnostic scanning to identify faulty wiring, sensors, or control modules.

When you start your 2008 Nissan Sentra, the engine RPM revs up abnormally with an unusual sound, but no warning light appears. You've had the fuel injector replaced at one dealer and the throttle body replaced at another, but the problem keeps coming back. The manufacturer has been notified of this recurring issue.
