Upon starting the vehicle the engine sounds as if parts are loose in the engine area. It lessens up after the engine warms up but is getting progressively worse. It appears it may be the timing chain/ tensioner.

While driving on 580 car lost all power without warning. Upon further investigation it was determined that the vacuum pump froze up, bolt on timing gear sheared off and fell into oil pan. Oil pump was destroyed as a result. On 11/7/13 received letter from MINICorp. Regarding a faulty timing chain tensioner with premature wear, which could cause problems. Upon replacement of tensioner assembly, mechanic found a faulty vacuum pump which froze without warning. Oil distribution was compromised. This abrupt loss of power put my entire family in jeopardy, which could have caused bodily injury or death. BMW corporation has been aware of the vacuum pump problem since 2012. Vehicle was purchased used in 3/15/11 with 32K miles. MINICorp lead me to believe that financial assistance may be made available for repairs. I have been declined any assistance for a failed vacuum pump assembly which caused catastrophic engine failure. The vehicle has had reports of similar failure. Highway speed, loss of power, putting vehicle and occupants in peril circumstance, BMW is aware of this issue and refuses to acknowledge design or manufacture/mechanical flaws in the engineering of this motor.

Complete loss of engine oil pressure while surrounded by semis in the 3/4-mile-long big walker mountain tunnel while traveling northbound on I-77 (near Virginia exit 47). Thankfully the engine didn't seize and I was able to pull off once through the tunnel. According to my mechanic, the cause was a check valve in the valve cover, which malfunctioned in a way that created a vacuum and trapped oil in the top part of the engine. Replacement cover had been redesigned to prevent the problem, so it seems to have been a known issue.

The car lost power and would not run at idle speed. After much effort, managed to get the car to the only dealer in the state. After two failed diagnostics and two "repairs, " the dealer says I now need the timing chain replaced. There are known issues about the timing chain and the tensioner. BMW and dealer deny responsibility and now wish to charge an additional $1500 to repair.

The timing chain guides and tensioner in the MINIcooper are made from plastic. There is a service bulletin created by MINIusa to address this issue, but no recall. As I was driving home, making a turn across a busy intersection, my tensioner broke, which caused my vehicle to die in the middle of a turn with oncoming traffic. I had to get out of my vehicle and push it across the intersection while cars were driving by. Although it is common for vehicle engines to die of different issues, this is a well-documented and acknowledged problem for MINIcoopers, but there has not been enough of a public outcry for a recall. The situation is dangerous, as it can cause engine failure which can result in a collision. The remedy is a replacement of a manufacturer-acknowledged faulty part.

Turbo oil cooling lines leaking engine oil on to hot turbocharger. This is a fire hazard. Many MINICooper S models are having this failure.

Have found that my MINIis having the exact same issues as those covered by the BMW service recall are having, although mine is not covered as confirmed by MINIcustomer relations. This should be extended to included all minis that are having this issue and not only those that opted for the upgraded model S.

Received a letter from MINIon 11/16/13 notifying me of possibility of faulty chain tensioner, which needed to be "checked for wear and replaced if necessary, " and that I should contact an authorized MINIdealer to arrange an appointment. No indication that the vehicle should not be driven. Two days later (11/18/13), just as I was about to schedule an appointment, the vehicle began to shake, then the red engine light came on, so I shut down the vehicle and had it towed first to the import shop that normally services the MINIthen, after consultation with that mechanic about MINIs recall letter, had it towed to a MINIdealership, where it now sits waiting for diagnosis and news about what any damage might cost to repair, whether I will be responsible for it, and whether I will be reimbursed for two tow charges and a car rental.

The contact owns 2007 MINICooper. The contact was driving 70 mph when the vehicle stalled. The vehicle was merged off road and towed to an independent mechanic where it was determined that the timing chain was fractured and caused the engine to fail. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in any recalls. The VIN was not available. The approximate failure mileage was 85,000.

My 2007 MINICooper S experienced the death rattle. I had to have the timing/tensioner chain replaced. This is a known defect and MINICooper should be required to recall their cars and fix them.

I was driving on the interstate, when without any warning or indicators, the engine shut off. I was stuck in a dangerous place, with high-speed traffic for sometime. The dealer who as my car says: "the primary cause of the engine failure was the locking up of the vacuum pump. Consequently this caused the bolt on the exhaust cam shaft sprocket to sheer off causing the vehicle to run out of time. The pistons therefore made contact with both intake and exhaust valves, verified with boroscope inspection, thus bending the valves and causing catastrophic failure to the engine. $6850 minus discount to replace engine. This is obviously not an isolated incident. I have had a lot issues with various MINIengine parts deteriorating, despite following the recommended regular maintenance schedules clutch, fly-wheel, thermostat, intake silencer, spark plugs, timing chain twice, waterpump, radio head unit, drive belt, hi-lo horn, boot latch, boot cable, to name a few. Hopefully MINIwill do something about these issues.

Ran a diagnostic test and these warnings came up - 2D52 super knocking 2dcd fuel shut off due to super knocking cylinder 3 2968 inlet camshaft sensor 2B64 intake manifold, unmetered air based on all of these sound like my MINIcooper has bad fuel and/or serious carbon build, I've just purchased this car from a dealership and I am experiencing delays in acceleration, loss of forward propulsion.

Upon acceleration when the turbo charger engages there is a high pitched squeal which changes tone depending upon the acceleration. Afterwards smokes starts leaking from the hood scoop and sides of the hood itself. It smells of burned oil. I noticed oil pooling at a connection point near the turbo charger unit. In mid-August the car failed it's emissions test due to a cracked valve cover. I had the MINIdealership replace the valve cover which was enough to pass inspection. However, the technician informed me that I had an oil leak in a line to the turbo charger that could start a fire and to watch my oil level closely. The cost to repair this (after nearly $900 on the valve cover) is simply beyond my means presently. Since learning about the possible dangers the car is no longer parked in the garage.

This vehicle has twice had a failure of the timing chain as a result of a faulty tensioner, resulting in catastrophic engine failure. The first incident occurred from a dead stop in a parking lot so there was no immediate safety issue. The second incident, occurring 12/03/2012, manifested as the vehicle was de-accelerating coming off a highway exit with a total loss of power at the bottom of the exit, in a remote area. MINIcooper sent their technicians in 2007 a "service bulletin, " short of a recall, when the trend was discovered among its "R56' model engines in 2008. I had warned MINIof sounds which later were determined by independent experts to be the timing chain's "death rattle" prior to the first failure, which they attributed to the car's "go-kart like start up." After 6 months of struggling, MINIagreed to 80% of the repair costs, with a new timing chain under a one year warranty. Other failures sidelined the vehicle for months in the intervening time, and due to the incredible cost of repair the vehicle had to be garaged until repaired. So although over a year passed between timing chain failures, about only about 39K miles were driven in that time. As of now, MINIis only offering 50% culpability, this after starting a vocal twitter campaign. I still owe $10K on a vehicle that requires up to $5K in repairs- a repair which will only replace a defective part with the same defective part.

Timing chain failure caused immediate engine failure at highway speed. Damaged timing chain housing cracked causing oil to spray the hot engine. Subsequent oil started a small fire that was extinguished by driver.
