Nissan Sentra: CVT Transmission Failure

Cost to fix: $3,800

The Nissan Sentra has an infamous reputation for expensive CVT transmission failures that could ruin your driving experience. A transmission failure is serious business. When this happens, your engine’s rotation will not be transferred to the wheels like it should, so the wheels will cease to rotate and you will not be able to accelerate in either drive or reverse. Until your transmission is repaired, your vehicle will be unable to move.

In order to avoid finding yourself stranded somewhere waiting for help to arrive, it’s best to keep a close eye on potential symptoms of transmission failure so you can stay on top of the situation. There are several telltale signs of a soon-to-fail transmission.

One is that your transmission is suddenly slipping unintentionally. You’ll be able to tell because your car will shift into different gears without warning, which is an immediate indication that your transmission is malfunctioning and needs to be fixed right away.

Rough or difficult shifting is a similar symptom, so if you have any difficulties with shifting at all, you’ll want to get that transmission inspected. Another sign is leaking transmission fluid. Check underneath your car every once in a while and look for pools of dark red liquid.

A good way to tell if the leak is active is to place some material in the spot where the leak is and see if it gets wet. If you experience strange, loud noises in your car like clunking or whining, that’s another indication. And of course, your check engine light is a surefire way to know that something is awry in your Nissan Sentra. 

The only real fix for this problem is a total transmission replacement. This is one of the most important parts of the car and it’s essential that you get a completely working unit. Because transmissions are so integral to a vehicle’s operation, it will likely run you about $3,800 for replacement.

Problem two: Blown Head Gasket

Cost to fix: $1,310

Head gaskets are a vital part of a vehicle’s engine, acting as the middleman between the engine’s cylinder block and cylinder head so that everything runs smoothly. The most common problem in Nissan Sentras is a blown head gasket, which causes coolant to enter the cylinders which can lead to a slew of issues. Your car will become unsafe to drive and your engine may lose power completely, so knowing the signals that this is happening is essential. 

Many of the symptoms have to do with strange occurrences in your oil or coolant, including sudden coolant loss, bubbling in the reservoir where coolant is held, or discolored oil that appears white. However, these aren’t the only ways to determine that your head gasket is blown.

Because the head gasket works to regulate heat, an overheated engine is a major sign that something is wrong. White smoke coming out of your tailpipe behind your car is also a key indicator. If any of these happen with your car, get it checked out right away.

It’s best to keep your coolant at the proper level and watch the temperature gauge every so often to make sure your car isn’t running hot, as this will help prevent this issue from occurring. In the occurrence of a blown head gasket, though, you will need to get it replaced at a shop. Most often this repair will cost around $1,310.

Another common problem with Nissan Sentra: Revving and Jerking

Cost to fix: $3,400

Another one of the issues people experience the most with Nissan Sentras are sudden revving and jerking. This has been reported in a variety of situations, including driving uphill and sitting in traffic. Revving and jerking can stem from a number of causes, including poor spark plugs, a mishap in the combustion process, a faulty fuel intake, or a clogged catalytic converter.

Due to the large amount of issues that can be causing your car to jerk when you accelerate, we recommend going to a mechanic to determine the right course of action. On average, fixing this problem costs $3,400.
