Engine Belts And Pulleys Problems of Volvo S40

Safety concern: 2007 Volvo S40 electronic throttle module failure - causing "reduced engine performance" message and vehicle (2007 Volvo S40) suddenly slows down while in motion, limps and cannot go higher speed. Had barely exited the freeway on 1/24/2017 and this happened as I was on ramp. Could be extremely dangerous if it happened 1 minute before when on freeway. Turned vehicle in right away to local Volvo dealership (which was luckily within 15 minutes) and they diagnosed it to be faulty electronic throttle module needing replacement. Mileage on car 129,000 miles. Wanted to report so this issue can be looked into for safety concern and if the huge cost of replacement can be offset so owners can have peace of mind replacing it timely if there is a recommendation or bulletin (similar to timing belts etc. - which I don't believe there is currently for electronic throttle module).

My serpentine belt broke on 6/6/2014 and was replaced. On 6/20/2014 I was driving about 60mph on the interstate in chicago, IL when my vehicle stopped accelerating and eventually stopped. This nearly caused an accident on the interstate, but I was able to pull to the left shoulder before being struck. I had to have the vehicle towed to a shop where it was determined that when the serpentine belt broke, shards of that belt went in to the timing belt area. This is due to a flawed design on my make of Volvo. The timing cover is not sealed, allowing particles to enter this area causing severe damage and nearly causing an accident. I have 20 bent valves that now need to be replaced due to this design flaw. There is no technician service bulletin that would have notified mechanics to be aware of this potential problem when a serpentine belt breaks, so my mechanic would not have known to look for this, which would have prevented the almost $3,000 worth of damage. This caused my car to completely shut down in the middle of traffic, which could have resulted in not only my death, but potentially other fatalities. I have requested Volvo correct what has occurred due to their design flaw, and lack of public notification but they have not agreed to do so. This is a known concern at the local Volvo dealership level, as my mechanic contacted a local Volvo dealership in orland park, IL and was advised by the mechanic that they are seeing this issue on not only my model, but other Volvo models as well. This problem, if it is not known to mechanics, can and did cause a complete loss of power in the vehicle. This increases the risk of a crash or potential fatality. As you can tell, I have few miles on my vehicle for it being 6 years old, so there is no reason for having to replace 20 valves in the engine, other than due to the design flaw. Thank you so much for your time.

I own a '07 Volvo S40 with 78,000 miles. It began making a loud whistling noise coming from the oil dipstick. After researching online I found that it was a known problem by Volvo and the defective part is covered under an extended warranty, however this defective part causes excessive damage to the engine that is not covered by Volvo. It is now up to the consumer to pay for the engine damage or it will cause the timing belt to snap and the engine to explode. An unsuspecting consumer can be fatally injured by this problem and something must be done about it!.

The contact owns a 2001 Volvo S40. The contact stated that while driving, the vehicle suddenly caught fire. The fire department extinguished the fire and the vehicle was destroyed. The vehicle had not been inspected for the cause of the fire. The current and failure mileages were approximately 86,000. Prior to the fire, the water pump and timing belt were replaced. Updated 04/19/11.

Engine failure. Car stalled while driving on highway. Car was towed to wynn Volvo. Was told that the belts broke, leading to the breakage of the timing belt, located inside the engine, resulting in major damage to the engine. Was given a quote of $5600 to repair. The car has 63000 miles and the manual does say that the belts need to be replace at 125 thousand miles. The services suggested prior to this does not include any of the belts being replaced. I believe that this should be a recall or atleast considered in the services and now. If this is considered, I would hope that this would warrant Volvo to repair my car at no cost to myself.

Engine failure. Car stalled while on highway. Upon arrival at Volvo service dealer, I was told that a drive belt broke, leading to the breakage of the timing belt and subsequent extreme damage to the engine. All belts, pistons, valves and top part of engine needed replacing. Approximate damage was $5000. Car has only 85k on it, drive belt and timing belt have a recommended replacement in manual as 125k. Volvo did nothing to acknowledge this issue, in fact calling out the service record which is impeccable minus a 50k service which would've cost $1500 and did not include any maintenance to the timing belt. In looking up this issue on many websites, it would appear this is not atypical for this make, model and year Volvo.

When attempting to start vehicle in the morning the first try results in loud shaking and shuttering. Sounds like car is not running on all cylinders, or has bad timing. Inital problem is that hood insulator fasteners are comming off which could come in contact with accessory drive belt and casue engine failure. Vehicle has been brought to dealer two times. Dealer said that the problem could not be duplicated. Problem occurs at least once every two days.

A slight squeaking or squealing noise could be heard from under the hood of the car, no visible defects apon inspection. The sound was the water pump failing. As I was taking the car to the mechanic the water pump failed (ceased) and caused the belt driving the water pump to snap. The water pump was driven by the timing belt. I am told that when the timing belt snaps that serious damage occurs to the engine. I cannot understand why a failure of such an ordinary part can cause such damage. Volvo stated that the repairs can run from 3-6 thousand dollars. I had to have the car towed, ferried and towed again to get to the closet dealer.
