Why Won’t My a Mercedes Start?

Mercedes GLE-Class wont start

Before we tackle the list of possible faults and fixes, it’s vital to first gain an understanding of the core problem. When you hop in your Mercedes GLE-Class and discover “it won’t start!”, there could be several components causing the headaches. Perhaps the engine doesn’t turn over whatsoever, or maybe it’s cranking but not firing. Or you might notice clicking sounds when you try to start it, but ultimately nothing happens. All these situations can signal different mechanical issues.

Common Reasons Why Your Mercedes GLE-Class Won’t Start

There are a host of culprits as to why your GLE-Class won’t start. The usual suspects include a dead or weak battery, broken alternator, starter motor complications, fuel system problems, plus electrical or wiring malfunctions. Each of these issues can present differently, needing specific methods of diagnosis and repair to get you back on the open road ASAP. All of which, we’ll delve into.

Symptoms of a Mercedes GLE-Class That Won’t Start

Identifying these warning signs will lead you to the main issue. For instance, when you turn the key or press the start button and you hear it turning over yet no start up, it often means a problem with either fuel delivery or ignition issues.

Analysis of The Reasons Why Your Mercedes GLE-Class Won’t Start

The initial move in solving the no-start nuisance is understanding the specific source of the trouble. So let’s explore the most frequent reasons behind the GLE-Class refusing to start when you turn the key.

Battery Issues in a Mercedes GLE-Class

In the majority of cases, the most common reason a Mercedes GLE-Class won’t start comes down to battery troubles. Specifically, a drained or weak battery prevents the engine from cranking. The car’s battery delivers the required power to start the engine and activate all your electronics. Symptoms of a failing battery include sluggish or strained cranking, faint headlights, or a battery alert symbol illuminated on the dash. A battery charger can recharge a dead battery if you don’t have the help of another vehicle to jump start it, but do have an electrical socket nearby like at home.  And a portable jump starter lets you charge p the battery without another vehicle, and by the roadside without the need for an electrical socket, so you are never stuck.

Alternator Problems in a Mercedes GLE-Class

car wont start alternator

The Alternator keeps the battery charged by harnessing engine power while driving. A worn out alternator can easily stop your Mercedes GLE-Class from starting since it fails to recharge the battery, draining it fully so that one day you climb into your wheels and it just can’t start. Signs of a wonky alternator can be an illuminated battery or alternator caution light on its dashboard, faint headlights while idling, or a whirring noise from the engine while running.

Starter Motor Failures in a Mercedes GLE-Class

car wont start wont turn over

The starter is crucial for turning the engine when you turn the key to start your Mercedes. Should the starter fail, the engine may fail to crank, keeping your GLE-Class from starting. Listen for clicking noises when you turn the key or grinding during cranking, possibly meaning starter issues.

Fuel System Issues in a Mercedes GLE-Class

We’re not talking about running out of gas like a silly goose. Rather, it’s issues with the fuel system itself potentially leaving your GLE-Class unable to start. Your Mercedes GLE-Class uses gas to mix with air and powers the engine. So problems here like a clogged fuel filter or damaged fuel pump relay may mean the engine is unable to get the fuel it requires for ignition. Fuel injectors can also get clogged over time, so try a fuel injector cleaner like Red Line to clear any blockages and improve starting.

Electrical System or Wiring Problems in a Mercedes GLE-Class

Ok, well yes that image is a joke, but I want to emphasize modern cars now rely heavily on electronics, opening up the number of things that can go wrong. With older Mercedes’s, the usual suspects include blown fuses, spark issues, faulty ignition switches, or broken sensors. Electrical issues and electronics like these may prevent your car from starting. Pay attention to intermittent starting, warning lights, or failure to crank as signs of an underlying electrical issue. Pinpointing and fixing these often needs a qualified mechanic near you.

Solutions: Let’s Get Your Mercedes GLE-Class Starting Again!

If you think you might know what the issue may be, it’s time to figure out the cause of your car’s failure to start, and then the next step is to attempt to repair the problem. Here’s advice for the typical issues we’ve discussed up to this point:

How to Identify and Fix Battery Issues in a Mercedes GLE-Class

car not starting but battery is fine

The first step if a battery issue is suspected for the no start is to have a look at the battery terminals. Make sure they are clean, tight, and properly connected. If the terminals are in fact corroded, try scrubbing them with a sodium bicarbonate(baking soda) and water solution.

Once you have checked the battery terminals, you can check to see if the battery is just out of charge, or worse, it’s old and weak, or dead and needs to be replaced. For this, you can charge the battery in a few different ways:

If the battery charges fully and performs as expected, the issue may be resolved. However, replacing the battery will be required if it is old, weak or dead. Otherwise, even sufficiently charging it to start your GLE-Class may only provide temporary relief before it runs out of charge again in the near future. Using a multimeter or OB2 scanner to evaluate the battery’s condition can determine if it’s worth preserving or requires replacement. Suitable replacement batteries for your specific Mercedes can be found on Amazon here by entering your vehicle details to filter for the right fit and choosing a highly-rated seller.

If charging your GLE-Class’s battery fails to solve ongoing issues like frequent draining and recharging even after installing a new battery, an underlying problem likely causes the excessive drain. Professional diagnostic services would then be needed to inspect and identify the root cause. You can also consult a mechanic online through us or obtain an instant quote from a mobile mechanic.

How to Identify and Fix Alternator Problems in a Mercedes GLE-Class

Car wont start replace alternator needed

If you think the alternator is the reason your vehicle won’t start, a test can confirm. If you can temporarily get the car running (you may need a jump start), and while it’s running, disconnect the positive terminal of your car’s battery. If the vehicle dies right quickly after that, it’s likely a bad alternator. Keep in mind though this test can be risky and damage delicate electronics in your ride, so seeking advice from a skilled mechanic in your area or online is best before trying it.

If you figure out that the alternator is the problem, it’s a case of having it replaced. I recommend consulting an online or local mechanic as they will advise you on how difficult the repair is for your specific model, and you can work out if you want to try it yourself, or with the advice of an online mechanic

If you do want to try it yourself or take it to a local garage, you can often buy the replacement parts yourself cheaper than at the garage, but you need to know what to get for your model of Mercedes GLE-Class. You find all the information you need about your specific vehicle by searching online for something like “vin lookup Mercedes“, which is a purchasable report, that will give the specs for your vehicle and which parts are compatible, and then you can go get the alternator parts you need. However, an easier option is, Amazon probably has the alternator you need online, at a cheaper price, and their site easily shows which ones will go in your specific car model. Check the Amazon alternator page here

How to Identify and Fix Starter Motor Problems in a Mercedes GLE-Class

If you suspect the starter motor is the reason behind your Mercedes not starting, be alert for a clicking sound when you turn the key. If heard, but the engine does not turn over, the starter motor likely needs replaced. You can take it to a local garage and have them repair it, or repair it yourself with the help and advice from an online mechanic guiding you. 

If you need it, one of the cheapest and easiest places to get a new starter motor, for your exact vehicle model is on the Amazon here.

How to Identify and Solve Fuel System Problems in a Mercedes GLE-Class

If you think a fuel system issue might be causing the no-start, listen closely for the fuel pump noise when you turn the key to “on” before attempting to start the car. The pump should make a faint humming for a few seconds. Should no such quiet hum be audible, the fuel pump could be defective. Difficult starting, stalling, or lagging acceleration may also stem from a blocked fuel filter. Filter and pump issues usually need a professional mechanic to inspect and repair them properly, often involving fuel pressure testing and specialized diagnostic equipment. Later in this article, I detail the best ways to get help from a local Mercedes mechanic near you. 

How to Repair Electrical or Wiring Issues in a Mercedes GLE-Class

If you suspect it’s an wiring issue, first inspect the fuses for the ignition system, and replace any that have blown. If your GLE-Class starts after this, it was an effective, inexpensive fix! But if your Mercedes GLE-Class refuses to start, even sometimes, the ignition switch itself could be faulty. Dash lights on the dashboard could also mean a damaged component. These can be intricate problems needing a qualified mechanic to identify and properly repair (see below advice on local mechanics).

How to Prevent Starting Issues in a Mercedes GLE-Class

As granpa used to say: “An ounce of prevention is worth a pound of cure”. Here’s how to avoid future troubles starting your GLE-Class:

Regular Upkeep of Your Mercedes GLE-Class

Regular maintenance on car to prevent starting issues

Routine maintenance is critical to avoiding issues, including oil changes, checking the battery, cleaning terminals, replacing the fuel filter as needed, and having a mechanic examine the car routinely. If confused about maintenance for your model, ask a mechanic locally or online for guidance.

Drive Your GLE-Class Frequently

If your Mercedes GLE-Class happens to sit unmoved in your garage or driveway for extended times without being driven, the battery can deplete as it is not being recharged by the engine running, through the alternator. Try your best to drive your vehicle regularly to keep a charged battery. If you remember you haven’t driven your car in a while, take it for a brief spin around town to ensure there is still a charge left.

Note: Letting the battery fully drain is also bad for its longevity, so try to avoid that.

Take Notice Of Warning Signs

If you notice any weird things like unusual noises, changes in driving and performance, or warning lights lit up on the dashboard, do not ignore them. These are often early signs of an issue that should be addressed ASAP before they escalate into larger problems later on. Consult with a mechanic locally or online about these problems and get advice on if they require attention.

When to Ask a Mercedes Mechanic Online

If your schedule is packed, or you gave fixing the no start yourself an honest effort but with no luck, consider consulting a Mercedes mechanic online. It delivers expert guidance in just minutes from the comfort of home, and is far less expensive than a tow and diagnosis at the local garage.

Frequently Asked Questions (FAQs) When a Mercedes GLE-Class Won’t Start

Mercedes GLE-Class won’t start but lights come on?

If your Mercedes GLE-Class‘s lights illuminate but it still won’t start, the issue is likely not related to the battery. More than likely there is a problem with the engine starter. Check to see if you hear any clicking noises when trying to turn the key. If so, the starter motor is attempting to activate but failing. Get a mechanic examine the starter motor – it may need to be repaired or replaced.

Mercedes GLE-Class won’t start but has power?

When your Mercedes GLE-Class has power (lights, radio etc work) but fails to start, there may be a fuel delivery problem. Issues like a faulty fuel pump relay could prevent fuel getting to the engine. Without enough fuel, combustion can’t happen and the engine won’t start.

They can accurately identify the specific electrical fault and have it repaired.

Mercedes GLE-Class won’t start just clicking?

When you turn the key and there’s only a clicking noise but the engine doesn’t crank, the most common cause is a faulty starter motor.
