Does our whole ABS system really need replacing?

The mechanic we took our Outlander to, to replace a wheel hub has said our vehicle need a whole new ABS system. The ABS light had never come on. No light has indicated anything wrong. Is it possible that our ABS system is gone without a warning light coming on? Not sure if we can trust the mechanic we took the vehicle to.

My car has 200000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi, thanks for writing in. In nearly 40 years of working on cars, and 30 years of anti-lock brake systems, I’ve never seen or heard of a single vehicle needing a "whole new ABS system" at one time, unless it was a miscommunication of what the vehicle might actually need. I’d be amazed if an entire ABS system – wheel speed sensors, ABS computer and ABS pump ALL failed at once. If you would like a second option, consider having an expert automotive technician from YourMechanic come to your home or office to inspect your ABS system for you.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

You can still drive without a functional ABS control module, as long as there`s no problem with your conventional brake system. However, take extra care, especially in wet or slick conditions, as the brakes` anti-lock element won`t work, and you likely won`t have steering control if your tires lock up.
Anti-lock brake systems, or ABS, are an essential safety feature for any car. When the system is damaged or needs a part to replace, it can cost anywhere from $320 to $1,000.
The most common ABS problems occur when sensors become contaminated with debris or metal shavings. Malfunctions also occur when sensor wiring becomes damaged, resulting in intermittent or no continuity.
What is the cost to resolve an illuminated ABS light? A good mechanic will charge about $100 for the initial diagnosis. Many ABS components are very accessible, so labor for most repairs will not run high typically in the $100 to $150 range.
The Brakes Lock Up

A bad ABS module can behave erratically, making your brakes lock up even under normal braking. You might even notice unusual behavior from the brakes, like random clicking noises.

When ABS is engaged, you can still manoeuvre around obstacles. Without ABS, when using maximum braking in a panic situation, you may lock your wheels and subsequently lose steering control.
The ABS module is like most electronic components in your car – it can be damaged by impact, electrical overloads, or extreme temperatures. Under most conditions, though, the ABS module should last the life of your car.
The average cost for ABS module replacement is $1174 to $1301. Enter your vehicle`s information to see how much ABS module replacement costs in your local area.
Are you wondering how ABS modules are repaired? There are lots of different ways for ABS modules to display signs of disrepair. An appropriate repair authority will be able to fix ABS issues that include a sudden ABS power loss, faulty wheel sensor codes, missing signals from the wheel speed sensor, and more.
The ABS could also be failing if you notice that your brake pedal is consistently locking up or is becoming increasingly difficult to push. After all, you can`t push the brakes if the mechanism simply won`t engage. Both of these symptoms indicate a problem with how the system is interacting with the pedal itself.
The cost of an ABS sensor replacement depends on the car you drive. But, it is fair to expect a charge between $100-$150 and labor costs between $100-$300.
This repair takes on average 0.90h – 1.10h for a mechanic to complete. If one of your car`s ABS speed sensors fails, a mechanic can take off your car`s tires and perform an ABS speed sensor replacement.
If the ABS system is not functioning properly, then your vehicle is likely to skid, hydroplane and lose traction under heavy braking conditions. The last time you want to find this out is when you need it most in tough conditions, which could lead to an accident on the road.
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car`s braking performance.
ABS should be repaired, eventually

If many state inspections don`t require the ABS system to be functional to pass, don`t assume that this system isn`t as important as the engine or suspension. A common ABS error is a wheel speed sensor fault.

It is rare for anti-lock brakes to fail. The ABS system is not critical for the primary function of braking, because the car will stop without the ABS engaging. However, without anti-lock brakes, a car will not have the traction control most drivers expect today.
In short, changes in the base brake system characteristics (hardware) may impact ABS/TCS/ESP performance in any or all of these three areas.
You can expect an ABS sensor to last 30,000 to 50,000 miles. If the sensor does fail, you should receive an ABS warning light on the dash, and your anti-lock braking system will not engage when needed.
As long as the ABS module is the same design and has the same ports on it then it will work just fine on your vehicle. Be sure to bleed all of the brake lines after replacing the module. If you need further assistance with your ABS module, then seek out a professional, such as one from Your Mechanic, to help you.
Without ABS, you still have normal brake functions. Drive and brake as you always have. Remember, if your ABS malfunctions, you still have regular brakes. Drive normally, but get the system serviced soon.
The good news is, replacing an ABS sensor is usually a straightforward task. In most cases, all you need to complete the job is a jack, jack stands, and basic hand tools.
The average cost for an Anti-lock Brake System (ABS) Diagnosis is between $83 and $105. Labor costs are estimated between $83 and $105.
Removing the ABS fuse can result in dangerous driving conditions, especially if you`re not prepared or have never done it before—so be sure to check in with a professional for a second opinion or further advice regarding your specific vehicle.

Does the CV boot need to be replaced or do i need to replace the whole axle? 2008 Chevrolet Uplander
ANSWER : Hello – the CV joint or axle boot is available separately from a variety of sources. What your mechanic may be saying however, is that given your mileage, it would be best to replace the whole axle assembly for reliability reasons. Replacing the CV boot requires considerable labor as well, and your best repair $ may be to go ahead and replace the whole axle assembly. I would recommend a CV axle replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Does the whole steering column need to be replaced in order to replace a fried steering column module?
ANSWER : I would ask the mechanic for the exact part number of the electronic component that he believes has failed. Or, at least have him "name" the part and indicate where in the column assembly the part resides. The steering column is made up of many parts, most of which are separately serviceable. As discussed below, limp mode (reduced power) has many, many causes. Consequently I would also ask the mechanic to explain to you EXACTLY how he arrived at his diagnosis and ALSO have him show you the exact test results, on a diagnostic tool, multi-meter, or scope, that has led him to conclude that the particular "module" has to be replaced. With no evidence and no intelligible confirmation you would be taking a risk.

YourMechanic does offer a reduced power (limp mode) diagnostic. If you request a reduced engine power diagnostic the responding certified mechanic will give you confirmation of the cause of the issue in your case. Typically, a vehicle’s powertrain control module (PCM) will have stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:

Defective throttle position (TP) sensor
Defective oxygen sensor
Defective accelerator pedal position (APP) sensor
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
A fault/error in the emissions system
A fault/error in the throttle control system
A fault/error in the transmission control system

If you request the recommended diagnostic the mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Do i need to replace the receiver drier and/or the expansion valve when replacing the condenser assembly?
ANSWER : Replacing the system drier is absolutely essential. If the system has been open to the atmosphere (due to the leak in the condenser), the desiccant in the drier has been fully saturated with moisture. As far as the expansion valve, replacement is not normally implicated in a leak repair, in your case a leak in the condenser. To justify replacing the expansion valve, there would have to have been a diagnostic performed which proved a fault. If no diagnostic was performed, and there is no evidence of a fault, then it is pointless to replace the valve. But, again, drier replacement is absolutely essential. To add the drier to your order, you can simply add a note to the mechanic in your order and/or add it as a service (you will see a link that you can click on to "add services" or write in specific services). If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Can the tie rods on a 2011 Nissan Juke be replaced without replacing the entire power steering system?
ANSWER : The tie rod ends for your vehicle, both the inner and the outer ends, are available for separate purchase. If you bought these tie rod ends yourself from an auto parts store, they’re "roughly" $50 each or $200 in total if you bought all four (your vehicle has a total of four). It would be unusual (indeed, exceptional) for tie rod ends to fail on a Nissan with only 36,000 miles on it. If you have a problem with the car, I suggest you get it evaluated by a TRUSTWORTHY, knowledgeable individual. A vehicle with 36,000 miles on it is frankly a brand new vehicle and to be in need of thousands of dollars worth of repairs would be unusual, excepting a circumstance where the vehicle was in a collision, abused, or otherwise damaged. If you have a steering issue, please simply request a steering system evaluation/diagnostic and the responding certified mechanic will thoroughly evaluate your vehicle, address your concerns and give you the information you need about any required repairs. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Chrysler 300 2005 abs not working. Code c2116. Does this mean my abs pump is dead for sure? Or could it be abs sensors.
ANSWER : Hi there. Take a digital volt meter and check the voltage on the harness to the ABS control motor. There should be a battery voltage present. If the voltage is low, then there is a break in the wiring from the computer to the ABS control motor. If the voltage is normal, then the ABS control motor has a burned cell and the ABS controller assembly would need replaced. This will effect the ESP system as well and set off the lights. If you need further assistance with your ABS system not working, then seek out a professional, such as one from Your Mechanic, to help you.

Do i really need to replace the ignition coil?
ANSWER : There are ways to test the output of the coil before it reaches the distributor cap.

Usually, if there is a problem with a spark plug wire, spark plug, or distributor cap, the problem is consistent. Those parts can be visually inspected and conclusively tested.

The coil affects all cylinders. It can be inconsistent with its output. Conditions like temperature and humidity can affect its performance.

The only way to test a coil is in person. I would recommend an inspection of your stalling condition by a qualified mechanic.
