Audi A4

"Cylinder 1 gives error codes Audi says can not be fixed . They have tried a variety of solutions, none work. The next step is to open it up, which may not fix it and the engine never be the same again"

"Piston #1 misses all the time and Audi could not fix it. Steering pump needed replacement and now it need a qt of oil ever 1500 mi."

"The car started going through 1 quart of oil every 400 miles. about a year ago and is still burning at that rate. The internet search indicated that his is a common problem and cost to repair is about $8000."

"It was burning oil so Audi did a ring job on it, and no problems since. It was on warranty"

"Excessive loss of oil required new rings"

"This model had a tendency to use excessive amounts of oil, and ours turned out to be one of them. I don't know all what the dealer did, but they had to pretty much rebuild the engine to fix the problem. And the problem is fixed."

"oil consumption high -Audi replaced the piston rings"

"tremendous oil consumption. Audi rebuilt pistons and rings at no charge"

"Around 100,000 kms (about 1 month after the AudiCare warranty expired) the engine oil consumption started increasing from about 1 litre per 5-7000 km to 1 litre per 3000 km. Nothing was noted by the dealership at 109,000 km servicing. When oil consumption increased to 1 litre per 1500 km (around 120,000 km and 9 months after last service), I booked another service appointment with dealership to check oil consumption issue. Four days prior to appointment, the engine failed at 120116 km. Had vehicle towed to dealership. Apparently the timing chain tensioner failed, caused piston to over-extend and damage cylinder head. Complete head & piston replacement required, including timing chain, tensioner, bearings & gaskets. As well, the turbocharger wastegate was found to be flapping in the breeze. Turbocharger replacement required. I suggested that this was very un-Audi-like and asked Audi to cover the cost of this kind of catastrophic product failure. Audi Canada offered to cover the cost of the parts however the parts don't install themselves and I was stuck with a $8,900 labor charge from the dealership, a cost that Audi has NOT reimbursed me for. I am surprised and I feel betrayed that Audi accepts no responsibility for this kind of product failure at 120,000 km. If you recall, when I last shared my Audi experience with CR, I praised the vehicle's lasting durability and lack of any issues with ownership. I do not feel that way anymore."

"Oil circulation to engine causing engine failure, also high oil consumption Engine failure at 44000 miles Audi response dealer service reports not available for life of car so no liability to them we were on our own"

"The engine consumed oil since it was new, at a rate or ~one quart every 3-4000 miles. Audi denied that it was a real "problem", but it persisted, and worsened at ~60000 miles, to one quart every 500 miles. Audi made no attempt to repair the problem, and unbeknownst to me, a class-action suit was brought against Audi by owners also experiencing this problem, which turned out to be a defect in the engineering of the engine, and which Audi settled by rebuilding the engines of those cars involved in the suit. But they did not notify me of this settlement, and my car's engine continued to deteriorate. At my service visit in mid-2019, they determined that the engine required rebuilding, a $7500 repair; the value of the vehicle at that time was in the range of $2000, so clearly not worth repairing. I am now in the market for a replacement vehicle."

"The engine was a problem and Audi/VW paid for 3/4 of the replacement/rebuild. We paid $3000. the other $2700 was for fuel pump, brakes, etc."

"Excessive oil usage, pistons replaced. Then had problem with turbo. Dealer wanted to charge 3k but Audi had extended Warranty to 7 years 70 thousand"

"Excessive oil consumption. Repair included new piston rings. Problem appears to be fixed"

"Engine had to be rebuilt in accordance to the class action lawsuit"

"Constantly burning or blowing out oil. Took several visits to dealership to verify damage and initiate a repair. Dealer finally rebuilt the engine to correct a PVC error"

"Oil in exhaust on acceleration and adding oil very frequently. Dealer ran diagnostics and replaced the rings in the engine without charge"

"Seems there is a common problem with these engines losing internal oil seal and directly adding oil to the incoming fuel mix. Got down to consuming 1 quart per 100 miles of driving. There is no option to replacing the engine other than replacing the car"

"At about 45000 mi, Car began burning almost as much oil as gas. Initially, dealer replaced defective turbocharger. Problem persisted. After much research discovered that this was common and Audi had a little-known court settlement requiring them to repair or replace the engine in these cases. Ultimately, the engine had to be pulled and completely rebuilt - took a month. While out of regular warranty, Audi had to pick up expense. Along with other problems like failing brakes, this is the least reliable car I have ever owned."

"Was eating oil, so needs to put in all new pistons"

"Oil consumption beyond manufacture specification"

"Car burns 3 quarts of oil per 1000 miles. this is insane. Shouldn't this be a recall to correct"

"All pistons will have to be replace due to excessive oil consumption"

"to much oil consumption"

"Engine was burning oil. Lawsuit was filed by plaintiffs in CA and mailed all audi drivers affected. Dealership did a complete engine rebuild covered by audi"

"It was replace under warranty"

"Engine burned (or otherwise lost) oil. After testing, dealer took car in and rebuilt engine. Rebuilt enine totally failed within one week. Dealer put in new engine. With new warranty"

"We are now subject to a class action suit where timing belts have had to be replaced at the amount of $2,400."

"Timing chain failed. Fortunately it was sitting in my garage when it happened. Car would not start. Audi repaired under warranty"

"The design of the original timing chain tensioner was faulty and at 52,000 miles allowed the chain to jump a tooth on the sprockets. This caused the engine to barely run without enough torque to run faster than about 20 mph. I learned that had the chain jumped one more tooth the valves would have been destroyed so the car was towed to a shop where the chain and tensioner were replaced. A class action suit was brought against Volkswagon of America (Audi's owner) about this issue and initially we were told that we would be reimbursed for the repair work only if it was performed by an authorized dealer (I used an independent) but recently I was told that charges from an independent would be covered up to the cost of a dealer's rate. So far I haven't seen any such reimbursement even though I submitted a claim several months ago."

"Replaced the turbo"

"Turbo gate valve went bad. Had to replace turbocharger"

"Turbo stopped working and cost 3,500.00 to replace"

"began running rough after 65K miles. Dealer unable to easily diagnose without $4000 commitment on my part; the problem was reading out in the computer diagnostics"

"Needed to have carbon build up removed from engine at 60,000 miles."

"Am not sure it is an oil leak, but car uses one quart of oil per 400 miles. Calls to Audi result in lame responses; Audi won't look at car without oil-change history; as we change oil ourselves, this is not possible. As a result, we would be responsible for poor engine quality and repairs to prevent this vehicle from burning oil and polluting."

"My 2011 Audi A4 began burning oil in 2018 and gradually became worse to the extent I was putting in a quart a week. Repair bill to completely rebuild engine was quoted at $5000. Sold it to dealer notifying them of issue."

"Rear crankshaft seal"

"Audi supposedly fixed high oil consumption which was up to 2 quarts every 10k. worked for about 15k miles now seems ti be using about the same. Also electronic dip stick is very unreliable showing partially full after adding quart and then days later showing full"

"Leakage internal to the engine that caused oil in the exhaust and excessive oil consumption by the engine"

"Audi doesn't think it's a problem, but I have to add engine oil every 5000 miles. Any other manufacturer would consider that an issue."

"It started using oil and now uses a quart about every 600 miles."

"The Audi A4 loses about 1 litre of oil every 1,700 km."

"Burns A LOT of oil. About a quart every 500 miles"

"Engine is burning 1 qt of oil every 700 miles. Audi not standing behind warranty to cover this known problem."

"Car experienced excessive oil consumption which was noted by me at the first service. The dealership changed the oil to "make sure it was at the correct level" and told me we'd see what was up at the next service. The excessive oil consumption stop"

"The car was consuming oil at a rate of 1 quart per 1,000 miles. The manufacturer did not send a recall notice, but there was a class action lawsuit. The dealer removed the engine and replaced some parts (it took over a week to complete) as part of"

"The car burns oil and when brought in to have this checked an oil leak was also identified. Still pending final testing on oil burning for potential repair under class action settlement"

"Steering pump failing, so that extremely hard to steer at slow speeds such as parking, as if it does not have power steering. I have not replaced this at $1000 due to the much bigger problem above; I do not want to put more money into this car. I am forced to replace it rather than risking a catastrophic failure with issue #1. Audi has not owned this problem, but I see for that model year it is much worse than average for Engine Major in CR reviews. Still, the car drives like a dream though"

"michigan roads caused them to break"

"Car Doesn't hold curves above 60mph"

"2 shocks have needed replacement, presumably due to age/mileage"

"Steering shaft and clockspring broke"

"Intermediate steering shaft pivot points seized."

"This car chews through tires very quickly, causing cupping and odd tire noise. 4 sets in last 90 k miles."

"Front wheel bearings had to be replaced at 88k"

"Both front wheel bearings required replacement this year"
