Check a BMW M3 advert (free) →The BMW M3 has 2 known faults in our database across 3 generations, 2 of them rated high severity. The most serious are engine (premature connecting rod bearing wear on the 4.0 V8 M3 built from 2007 to 2013) and suspension (rear subframe / floor pan cracking and tearing away from the chassis). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.
One owner each, in their own words rewritten as a line, and not counted in our risk scoring. A fault joins the list above once a second report or an editorial source backs it.
Sellers rarely admit these faults outright

They do not tell you whether this particular car has had the work: for that, put the registration into the free GOV.UK MOT history check, which shows a recall status where the manufacturer shares it, or ask a franchised dealer to check the VIN.

On affected vehicles ingress of transmission fluid may occur to the integrated transmission control unit within the mechatronic module
Put right by: On affected vehicles the transmission mechatronic module will be replaced
A possible degradation of airbag propellant tablets could lead to an over-aggressive combustion in the event the airbag is activated which may cause the inflator body to rupture.

Put right by: On affected vehicles the screw connection of the lower belt of the front seats will be checked and if necessary reworked.
The flange of the propshaft may become detached.
Put right by: Replace the propshaft with a alternative construction.
It is possible that the connection between the B+ cable and the Power Distribution Box can become damaged by wear and heat which is caused by high current flow and high contact resistance. Normally this will result in a non-start situation after parking the vehicle. However it is possible that this could in extreme cases occur whilst the vehicle is in motion. The driver should be made aware of the issue by flickering of the instrument cluster (dash) or an engine mis-fire; but if the driver does not then the engine could cut-out without warning.
Put right by: Recall all affected vehicles with petrol engines and replace the cable/connection with a more robust item.
The propshaft slide joint may not have been lubricated during manufacture
Put right by: On affected vehicles check propshaft and hwere necessary replace propshaft.
On affected vehicles the Driver's seatbelt retractor may be faulty. The seat belt may be hard to pull out or below zero degrees it may not be possible to pull the belt out. In these instances a driver may not be able to use the belt as intended.
Put right by: On affected vehicles Check belt operation and replace belt if necessary
Recall data published by the Driver and Vehicle Standards Agency under the Open Government Licence v3.0. A recall listed here may not apply to every car of this model: the build dates and the registration check are what decide it.
A timing chain has no change interval, which is not the same as lasting for ever. Listen for it on a used M3, and check the oil has been changed on time. These are the figures UK specialists work to.
S65 engines suffer from premature connecting rod bearing wear. Specialists treat replacing the bearings as preventative maintenance to do before 70,000 miles. Failure to replace can lead to total engine destruction.
The primary notorious failure on the S65 is rod bearings, not the timing chain. However, high-mileage examples can experience wear on the timing chain tensioners and guides. If you hear rattling separate from the typical top-end tick, have the tensioners inspected.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
No BMW M3 year is a write-off, but the E90 / E92 / E93 (2007 to 2013) carries the most serious faults: engine. The E46 (2000 to 2006) has high-severity faults on record too. The F80 (2014 to 2018) has none rated high severity. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the engine and suspension faults on this page and whether they have been fixed, with invoices. On the test drive watch for deep metallic knocking from the crankcase and creaking or popping noise from the rear over bumps. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against its known faults before you travel. Check a BMW M3 advert →
