Used, red Alfa Romeo Brera on OEM alloy wheels.

 

Reliability & common problems

This section covers the potential reliability issues that you might have with the Alfa Romeo Brera. Click on the buttons below to read more about the typical problems that fall outside the scope of routine maintenance.

M32 gearbox bearings

The 1.75 TBi and 2.2 JTS engines are paired with the infamous M32 gearbox in the Alfa Romeo Brera. A typical problem with this 6-speed transmission is bearing wear. In particular, the 6th gear bearing.

When this bearing starts wearing out, the gearbox becomes noisy when driving in 6th and 5th gear. If not fixed, this problem leads to total gearbox failure (a hole in the gearbox).

The M32 gearbox is used in so many vehicles, and bearing failure is so common in high-mileage cars, that I’ve dedicated a full page to the M32 transmission.

Follow the link above to learn more about the symptoms of bearing failure, the solution to the problem and how much it costs to fix a dying M32 gearbox.

The 3.2 JTS and the JTDm engines have the stronger F40 gearbox, which should last a lot longer.

Selespeed transmission failure

The Selespeed transmission is an automated manual transmission, which means that the car has a manual transmission and a Selespeed robotic unit attached to it. The robot does the gear shifting for you, you lazy bastard.

You might have also heard about Fiat’s Dualogic transmission. Fiat’s Dualogic and Alfa Romeo’s Selespeed are pretty much the same thing.

Let me very briefly explain the basics of this transmission. The Selespeed robot is a complex hydraulic device, made up of solenoid valves, sensors and actuators. It is powered by a little hydraulic pump, and it has its own hydraulic fluid circuit.

The oil is pressurized by the pump and then stored in a hydraulic accumulator. The accumulator has a rubber diaphragm inside and compressed nitrogen gas behind the diaphragm. Therefore, there is compressed gas on one side of the diaphragm and hydraulic fluid on the other.

The diaphragm can deflect to store energy (oil pressure) because nitrogen gas is compressible, while the oil isn’t. This stored energy is then used to do the mechanical work – changing gears and operating the clutch, which is what the actuators do.

Because there is no torque converter, the Selespeed can be as efficient as a manual gearbox. However, it’s not as smooth as a traditional automatic transmission, and in my opinion, not as reliable.

The problem is that it is a relatively advanced piece of machinery and a failure of an individual component, like a £20 sensor or a £5 seal, means that you may have to replace the entire Selespeed unit, which is very expensive.

You may be able to replace an individual part that failed if you can find someone capable of doing it, but it will take some effort and time as there aren’t that many places that can fix Selespeed robots.

I am fairly confident that if you simply go to the dealership with a faulty Selespeed gearbox and the problem is not something obvious or easy to replace like an accumulator or a hydraulic pump, they will try to replace the entire unit for £2,000.

 

My recommendation is to avoid Selespeed transmissions when buying a used car. However, if you are still determined to buy one, here are the symptoms of Selespeed malfunction:

  • dropping into neutral on its own (this can happen at motorway speeds)

  • jerky gear changes

  • transmission warning messages on the dashboard

  • inability to select gears or missing gears

When the Selespeed transmission stops working, the first thing to check is the accumulator. Over time, the membrane inside can rupture and the accumulator will stop storing pressure. Even if the membrane is still fine and you don’t drive the car much, the nitrogen gas will eventually escape, just like air escapes from a seemingly airtight balloon.

It’s the same story as with the nitrogen spheres used in Citroën’s hydro-pneumatic suspension and Mercedes-Benz’ ABC. Because it could take a decade, the odds are that the membrane will fail before the gas disappears from the sphere.

Don’t worry about the accumulator though. It’s easy to replace. It’s just everything else that should worry you – the solenoids, the seals and sensors inside the Selespeed robotic unit.

Power steering issues

There have been cases of prematurely worn-out steering racks and power steering pumps in the Alfa Romeo 159 and the Brera. The reasons for these problems are twofold.

First, the early power steering reservoirs had a problematic non-return valve inside that may cause the oil to froth. This is a problem because the power steering pump cannot operate correctly with air in the system – it becomes noisy. The reservoir was later updated to fix this issue.

Second, the red GI/E power steering fluid filled by the factory in the first years of production was later deemed not up to the job. In 2009, the fluid was changed to green GI/R oil. This is a bit of a controversial topic as there is a lot of conflicting information. For a while, even the Alfa Romeo dealers did not know which fluid was the right one.

A whining power steering pump can often be cured by just replacing the reservoir and changing the power steering fluid to the green GI/R oil.

There is a catch though – the green fluid is thinner than the red one. There have been cases of steering racks developing leaks after switching to the green fluid – this applies mainly to high mileage cars that had been filled with the red fluid for some time.

To improve your odds of not having to replace the steering rack or the power steering pump:

  • Look for a 2009 or 2010 car, and make sure it has the green GI/R fluid in it

  • Pay extra attention to any issues related to the power steering. The typical symptoms of steering rack or pump failure are:

    • pump whine – most noticeable when turning the steering wheel at low speeds or at standstill (check this twice – with a cold and a hot engine)

    • creaking and knocking noises when turning at low speeds

    • fluid leaks from the steering rack

    • play in the steering wheel or notchy steering wheel movement

    • loose steering feel

Red paint & stone chips

The “Alfa Red” aka “Rosso Alfa” paint is noticeably weaker in terms of resistance to chipping than other colours.

This seems to affect all Alfa Romeo cars made a few years before 2010. The problem was noticed by Alfa Romeo as they’ve temporarily stopped selling red Mitos and Giuliettas in 2010. Many cars had body panels resprayed as part of the manufacturer’s warranty due to stone chips.

It looks like they’ve managed to improve their red paint after 2010.

The red paint problem is not limited to Alfa Romeo. Other manufacturers were also having problems with red paint around that time. I believe it had something to do with environmental restrictions on paint formulas.

By the way, this reminds me of the problems Mercedes-Benz had with corrosion and water-based paint in the late-1990s.

If you want to buy a red Alfa Romeo Brera, inspect the paint more thoroughly than you normally would. If you find a lot of stone chips, try to negotiate a discount. The body parts that are affected the most are the wheel arches, the front bumper and the bonnet.

2.2 JTS – timing chain wear

The 2.2 JTS is based on the General Motors Z22SE engine. Alfa Romeo modernized this engine by fitting it with variable valve timing and direct fuel injection called “Jet Thrust Stoichiometric”.

The problem here is that GM’s Z22SE engines had a bad reputation for snapping timing chains. Vauxhall/Opel improved that engine in 2002 by updating the oil feed nozzle that lubricates the timing chains.

The original nozzle had a 1 mm internal hole, which would quickly get clogged up. Clogged oil spray nozzle = no timing chain lubrication. The updated, post-2002 nozzle had a 4 mm internal passage, which reduced the likelihood of oil starvation.

Later, the Z22SE received direct petrol injection and became Opel/Vauxhall’s first direct injection engine. The updated engine was called the Z22YH and was used in a few Opel/Vauxhall cars, for example, the Zafira B (which is known for catching fire, by the way).

So, how is this all related to the 2.2 JTS?

When the Brera was on the drawing board, Alfa Romeo, Fiat and General Motors were one big corporation. Alfa Romeo decided to leverage their synergies by using GM’s engine designs. However, it seems they leveraged the wrong ones…

In other words, the Alfa Romeo 2.2 JTS, is back to the 1 mm oil feed nozzle. So much for value-added decision making.

On top of that, the oil change interval in the Alfa Romeo engines is 18,000 or 21,000 miles, which is far too long for the 2.2 JTS as there is bound to be some sludge build-up and oil degradation after so many miles.

The result is a timing chain that can wear out as early as 20,000 miles in the worst case. Best case? Maybe 100,000 miles.

The saving grace of the 2.2 JTS engine is that the camshaft position sensors can usually detect a worn-out timing chain before it stretches to the point where it becomes dangerous. Typically, the first indication of a stretched chain is the “Check Engine” light and camshaft position errors stored in car’s memory (most commonly P0016).

The second symptom of a stretched timing chain is noise. Here’s more about timing chains and how to do a basic timing chain check.

I can’t recommend this engine (nor the M32 gearbox attached to it), but if you are hell bent on getting one, here’s what you could do:

  • Use a good quality synthetic oil and replace it every 10,000 miles or yearly, whichever comes first.

  • Imagine that the car has a timing belt instead of a chain – by adjusting your expectations you’ll be less pissed off when the timing chains start acting up. Replace the oil feed nozzle with the updated one when you replace the timing chains.

  • Buy a car that had the chains and oil feed nozzle recently replaced, so that you don’t have to pay for it yourself.

3.2 JTS – timing chain stretch

The 3.2 JTS (“Jet Thrust Stoichiometric”) is a direct injection engine based on the General Motors “High Feature” engine. The same engine block is used in a whole bunch of cars: Vauxhall, Opel, Holden, Saab, Cadillac, Buick, Chevrolet, Pontiac, Saturn and Daewoo. There is one thing that potentially affects many of these cars, and it is premature timing chain wear.

There are three timing chains in this engine and there have been cases of these chains stretching, which affects camshaft timing. The chains will have to be replaced at some point, either under your ownership or someone else’s. Typically, premature chain wear comes from poor lubrication, design flaws or material issues.

“Premature” and “poor lubrication” – I’m not sure if I like where this is heading…

What I do know for sure is that the timing chain system in this engine is complex – much more so than in a 4-cylinder engine. That’s why timing chain replacement in the Brera 3.2 JTS is expensive.

I think it’s a materials issue, aggravated by long oil change intervals that makes the timing chains in the 3.2 JTS engines stretch. Opel/Vauxhall updated the timing chains in 2010 to improve their longevity (Technical Service Bulletin 2895). This update didn’t have a chance to reach the Brera as its production stopped in 2010.

The timing chain wear symptoms in the Alfa Romeo Brera 3.2 JTS include:

  • engine misfire and rough idle

  • intermittent “Check Engine” light

  • error codes P0016, P0017 or P0018 stored in the car’s ECU

  • rattling noises coming from the engine (chain slap) at start up (especially cold start)

  • noisy engine

  • reduced power and fuel economy

Buying a high-mileage Alfa Romeo Brera 3.2 JTS is a bit risky. If anything goes wrong with the complex timing chain system, you may be left with a huge bill.

You can expect to pay over £3000 at the dealership for timing chain replacement. Timing chain issues in the 3.2 JTS are less common than in the 2.2 JTS, however, chain replacement is a lot more expensive.

You could potentially save some money by purchasing General Motors parts that tend to be cheaper than Alfa Romeo’s parts. If you shop around and to this job at an independent garage, you could reduce the total cost to below £2000.

As a precaution (to reduce chain wear), I recommend replacing the engine oil sooner than every 18,000 or 21,000 miles, which is what Alfa Romeo used to recommend for the 3.2 JTS engine. I’d say 10,000 miles is a safe interval for this engine. It’s cheap insurance when you compare the cost of a few extra oil changes with the cost of timing chains replacement.

If you are looking to buy a car with the 3.2 JTS, try finding one whose owner has been changing the oil more often than the service manual specifies and make sure there are no symptoms of stretched timing chains.

At least the chains are at the front of the engine, away from the gearbox. If this was an Audi or a Volkswagen V6 car, you’d pay even more for timing chains service because those engines have four timing chains and they are at the back of the engine.

The glass is half full.

2.4 JTDm – timing belt & water pump

According to the manufacturer, the timing belt in this engine needs to be replaced every 72,000 miles or 5 years, whichever comes first. In my opinion, this is too optimistic. I recommend getting it replaced not later than 60,000 miles.

The water pump must be replaced at the same time as the timing belt, otherwise, it can seize and cause the timing belt to snap. It’s actually the water pump that is the weak point in the timing belt drive and the first part to fail.

2.4 JTDm – swirl flaps

From mid-2005, these engines were fitted with swirl flaps in the intake manifold in order to improve emissions. There are two types of intake manifolds that were used on the JTDm and MultiJet engines.

Luckily, the 2.4 JTDm 20v has the safer aluminium manifold with plastic swirl flaps. These rarely fall off, unlike the metal ones that sometimes get detached and ingested by the engine.

In these engines, the swirl flap bearings wear out when the carbon build-up in the intake manifold becomes severe (it will eventually). Once the bearings are worn, they may develop air leaks, allowing the boost pressure to escape. Also, the flaps can simply get stuck before the bearings wear out.

Stuck or leaking swirl flaps manifest as:

  • Rough engine running

  • Reduced fuel economy

  • Reduced power

  • The “Check engine” light may turn on as well

The main cause of flap failure is increased friction in the flap mechanism from the carbon build-up in the intake manifold. Carbon build-up is a byproduct of the exhaust gas recirculation system (EGR) that feeds exhaust fumes back into the engine to improve emissions.

To fix the swirl flaps, a new intake manifold is required, which is fairly expensive. Another option is to remove the swirl flaps altogether, which has a minimal impact on the engine running. There are swirl flap removal kits available on the market.

Please be aware that removing the swirl flaps will increase emissions and is probably illegal – it depends on the country you live in.

2.4 JTDm – worn drive shafts

The 20-valve JTDm engine has an appetite for drive shafts. It seems that the General Motors drive shafts used in the 20-valve JTDm cars don’t last as long the Alfa Romeo ones used in the older 10-valve JTD cars.

Make sure the drive shafts are in good condition in the car you are planning to buy, so you don’t get shafted. Look out for vibration when accelerating. It may be more noticeable in high gears at speeds above 50 mph.

Also, take the car to a parking lot or some other place where there is enough room to manoeuvre. Open both front windows, turn the steering wheel all the way to one direction, then do a circle. Listen for any noises coming from the CV joints.

Here’s what you don’t want to hear:

Summary or problems & additional information

  • The Alfa Romeo Brera is based on the same platform as the Alfa Romeo 159. You can think of the Brera as a coupé version of the 159. Fun fact: the Brera and the 159 front bumpers can be swapped.

  • The suspension in the Brera is more durable than it was in the previous generation of Alfa Romeo cars such as the GT or the 156.

  • There have been cases of prematurely worn-out steering racks and power steering pumps in the Alfa Romeo Brera. To avoid problems, look for a 2009 or 2010 car, and make sure it has the green GI/R power steering fluid in it.

  • The 1.750 TBi and 2.2 JTS engines are mated to the infamous M32 gearbox. A typical problem with this 6-speed transmission is bearing wear. In particular, the 6th gear bearing. The 3.2 JTS and the JTDm engines have the F40 gearbox, which should last a lot longer.

  • I don’t recommend buying a used Alfa Romeo with the Selespeed transmission. It’s not something you want to own outside of warranty.

  • The “Alfa Red” aka “Rosso Alfa” paint is the weakest in terms of resistance to stone chips. The difference from other colours is noticeable, especially if you do a lot of motorway driving.

  • The 2.2 JTS and 3.2 JTS engines are fitted with timing chains. The other engines have timing belts. The timing belts turned out to be a better solution in the Alfa Romeo Brera because both JTS engines are prone to premature timing chain wear, especially the 2.2 JTS. Here’s more about timing chains and how to do a basic timing chain check.

  • The 2.0 JTDm is an evolution of the popular 1.9 JTDm. It’s a good engine with no major flaws. The things that could go wrong are the same as for all modern diesel engines.

  • As for the 2.4 JTDm, it’s a great engine but it has a few problems. Watch out for worn drive shafts and you will likely need to deal with the swirl flaps at some point. Also, do not delay replacing the timing belt and water pump in these engines.

  • I once heard that buying an Alfa Romeo is like dating a stripper – you know you shouldn’t, but it can be a hell lot of fun though. It’s a bit like that with the Brera – it’a sexy car, but she has some issues. You can’t avoid all of the problems, but you can greatly reduce the potential maintenance costs by getting a 2009/2010 car that’s not red and that doesn’t have the Selespeed transmission.

  • Here’s my take on the engines in the Brera.

    • The 1.75 Tbi has a good reputation and no major flaws, however, it’s not a common engine so finding one might take some time. The main drawback of the 1.75 TBi is that it’s mated to the M32 gearbox.

    • The 2.4 JTDm is a reliable engine provided that you deal with the swirl flaps and other nuisances that affect modern common rail diesel engines.

    • The 2.0 JTDm does not sound as good as the 2.4 JTDm, but the swirl flap design is much better. This engine is a more financially sensible choice, albeit a more boring one.

    • The 3.2 JTS is somewhere in the middle because of potential (expensive) problems with the timing chains and poor fuel economy.

    • The 2.2 JTS is the worst choice because of the timing chain problems and chocolate bearings in the gearbox. Not to mention that it doesn’t sound as nice as the V6 or even the inline-5 JTDm engine.
