Vauxhall Astra (2015–)

What's good

Very good ride quality.

Economical yet smooth 1.6 CDTi diesel engine while the 1.0 Ecotec petrol is very impressive.

Five star Euro NCAP rating. 86% adult occupant safety, 84% child occupant safety, 83% pedestrian safety, 75% safety assist.

What to watch out for

Fiddly ventilation and air conditioning controls.

No spare wheel and no spare wheel well either.

10-12-2016: Report of Vauxhall Astra 1.0 Ecoflex, bought 2nd hand from a Vauxhall dealer, cutting out three times in a week at 60mph. Dealer mentioned faulty crankshaft position sender and two wires touching. Owner can reject the car.

9-5-2017: Complaint of scraping noise from brakes of 2016 Astra 1.4 T (150) despite dealer having replaced the pads.

17-7-2017: Problem reported with stop-start of February 2017 Vauxhall Astra 1.0T. The ignition stayed on though the key was out of the car. Then the owner became locked out by the anti-hijack and needed help manually breaking in (there is no visible keyhole so unscrewing the handle was required). Owner took it into the dealer who had it for a day then pronounced it fine. 3 days later owner experienced the engine continuing to run with the key removed from the car. To stop it owner had to put the key back into the ignition. When owner removed the key again the ignition remained on, so called the AA man who said that he had never encountered anything like it in 30 years. Owner then took the car back to the dealer and, to his consternation, handed him the key while the car engine continued to run in the car parked outside.

18-9-2017: Report of insufficient drainage to the front door bottoms when Vauxhall Astra Ks are parked facing uphill. The result is significant quantities of water collecting in the door bottoms.

31-1-2018: Report of condensation behind infotainment screen of 2017 Vauxhall Astra 1.4 100 VVT Ecotec-4 Tech Line 5dr Estate when the heating is used. Could be duew to a leaking heater matrix.

31-1-2018: Report of nearside rear brake caliper of 2016 Vauxhall Astra 1.4T automatic seizing at 19k miles. Owner told there were no replacement rear calipers in the country, so had to resort to a temporary fix by his local garage.

22-2-2018: Report from reader that his March 2017 Astra 1.6CDTI had a software upgrade at 7,500 miles. He records details of fuel, mileage, mpg, etc. on a spreadsheet. From new, he used supermarket diesel, but changed to Shell V-Power diesel at 8,852 miles. At 8,600 miles he had checked the app and the onboard system and the the oil life was 54%. At 9,600 miles the oil life had dropped to 5%. He says that after changing to Shell V-Power his mpg dropped to 55mpg, whereas previously it has been low 60s. This will have had nothing to do with changing to Shell V-Power and everything to do with the software upgrade that, by reducing NOx, increased soot emissions, requiring more frequent active regenerations of the DPF that uses post-injected fuel, hence more fuel used and greater contamination of the sump oil.

11-8-2018: Report of multiple electrical failures on 2017 Astra K 1.4T automatic: "On a 50 mile trip the car started going into "limp home" mode, cured by switching off/on, then, coming back on the M1, the dash blacked out for a few miles, returning to life with the speed limiter on at 65mph. Finally, when reversing up to my garage the reversing sensor did not work."

13-8-2018: Report of heater failing on 2015 Vauxhall Astra.

22-9-2018: Report of problems with a new Vauxhall Astra purchased April 2018. Broke down at 106 miles with no oil in the engine due to an oil leak. Vauxhall dealer replaced the engine. New no 1 coilpack fitted and wheels balanced. Car still has steering problems. Spanner symbol came on the dashboard and driver couldn't move steering wheel. Turned engine off for 5 minutes then turned it on again and drove really slowly to get home. He has experienced loss of power and still problems with the steering. Wants a replacement car. Vauxhall is refusing saying that they replaced the engine because of an oil leak (even though nothing came on dashboard display) as a goodwill gesture. They also replaced the coil as a goodwill gesture and will not accept his rejection.

24-10-2018: Minor grumbles with November 2017 Vauxhall Astra Elite 1.4 petrol automatic: The blind spot warning light in the driver side mirror gives false warnings. This happens perhaps one day in ten – and usually (but not always) when it is raining. Also, the entertainment system will sometimes fail to recognise the USB stick (containing music files) – around one start in fifteen – even though the USB stick is never removed.

2-11-2018: Report of clutch pedal sticking down in 2017 Vauxhall Astra 1.6CTDI bought used (ex Motability) at 16,800 miles and now with 24,800 miles. Required a toe underneath to raise it. Reported to Vauxhall dealer at service and owner told it was a "known fault for a small number of cars in a specific gearbox number range" After the system had been stripped down, owner told that the clutch was so badly worn it needed replacement at a cost of almost £400. After some argument, owner was advised that clutch and dual mass flywheel would be replaced under warranty because the cause of the failure was the sticking clutch engagement system.

11-2-2019: Report of problem from a fleet manager with the braking system of 2016-2018 Vauxhall Astrta 1.6CDTIs: if the brake pedal is applied slowly and constantly, the driver might experience a reduction in braking power and an extended pedal travel. However, under general circumstances, including emergency braking, the system operates as designed. If a driver feels that the pedal is not responding correctly, please remove your foot from the brake pedal and reapply firmly. In line with this priority and that of continuous improvement, Vauxhall has introduced as a Product Safety Recall a modification to the Electronic Climate Control in which the following steps are followed in order to ensure the continuous safety of the vehicle; change of blower motor, change of blower motor regulator, installation of new water deflector (which reduces potential for corrosion in the blower motor) and wiring harness. With the braking problem it only seems to be diesel engines with manual boxes that are affected.

1-6-2019: Report of dashboard warning lights of 2016/66 Vauxhall Astra 1.6 petrol model repeatedly lighting up spuriously. Dealer clears the faut codes, then it happens again.

3-6-2019: Report of piston failure in engine of 2016/66 Vauxhall Astra 1.4T automatic at 29k miles. Driving school car but fully serviced on time and Vauxhall is repairing under warranty, but taking a long time depriving the owner of income.

3-6-2019: Extraordinary saga of clutch failure of 2017 Vauxhall Astra 1.4 Turbo Petrol 6 speed gearbox in June 2018 after only 7,000 miles. Clutch, Flywheel and slave cylinder replaced under Warranty. Clutch failed again February 2019. Entire engine unit replaced under warranty after only 8,500 miles. Clutch failed again NINE times between February and May. Car now returned to supplying dealer who is asking Vauxhall to investigate the problem.

25-6-2019: Report of failure of engine of 2016/66 Vauxhall Astra 1.4T automatic. Has now been with the dealer for more than a month and dealer cannot give a date when warranty replacement of engine can be carried out. Dealer says has 3 more Astras with the same issue.

3-7-2019: Another report of engine failure in an Astra K 1.4T. " My Vauxhall astra 1.4t 66 plate suffered engine faliure (pistons) under warranty. After 5 weeks my car I've been told is finally ready to collect from the dealership." Owner then questioned the future reliability of his engine.

4-7-2019: Report of 'long block' of Vauxhall Astra K 1.4T being replaced under warranty.

9-7-2019: Report in Ask of fault message 'Reduced performance, reduce clutch use' come up, followed by 'Service: Transmission' on 2019 Vauxhall Astra 1.6 Eco at 5,500 miles. Owner called breakdown out who advised it's a clear clutch and transmission fault, probably sensors that may require them to be rewired, reprogrammed or, if gearbox affected, then gearbox taken apart and rebuilt. "Revs were all over the place and gear notifications went berserk, but car didnt go into limp mode." Taken to dealership who are going to look at it under warranty. (Previous reports of someting similar 1-7-2019 and 3-6-2019.)

22-7-2019: Report of 2016 Vauxhall Astra 1.6 ST estate recalled dor brake issue. After, the radio and now dashboard power have intermittent failures. Because car was more than 3 years old, dealer demanded £99 'diagnostics' fee to investigate. No justification for this. Should be FoC.

28-7-2019: Report of piston failure in 2016/66 Vauxhall Astra at 35,000 miles (engine not specified, but presumed 1.4T) " A £1100 set of diagnostic tests have revealed a broken piston which could cost up to £1,800 to repair." Owner awaiting decision from Vauxhall, but worried that the warranty was voided
because the car missed its first service and did not change the oil until the check engine light came on. The car was bought second-hand in May 2017 from a Vauxhall garage in Crawley with 11 miles on the clock. More about the problem here: https://www.astrakforums.co.uk/viewtopic.php?f=11&t=4493#p39994

30-7-2019: Report of failure of turbo on 2016 Vauxhall Astra 1.6 turbodiesel at 47,000 miles.

12-8-2019: Report of engine overheating on longer journeys in 2015 Vauxhall Astra GTC 1.4 turbo petrol, engine type B14NET. Vauxhall dealer diagnosed an 'Engine flow error' and fitted a new water pump and thermostat. About a month later on a journey for over an hour owner found that when accelerating quite hard on a crawler lane uphill, the engine temperature gauge was rising from the 90c mark towards the red area at 130c. This time though, the engine did cool itself down rapidly and the fan was running for about 10 minutes after owner got home when i had parked up. He took it back to his local Vauxhall dealer who have road tested and used the diagnostic equipment and they have advised no fault found with the vehicle's cooling system. Otherwise, it drives superbly. (Might be the beginnings of the infamous engine failure due to being filled with the wrong oil on the assembly line.)

19-8-2019: Report of series of problems with 2015 Opel Astra 1.4 turbo Essentia manual, bought used in to16 at 15,000km. 2015. Within a few months owner had to replace the water pump. Then the thermostat housing perished without warning that the car was overheating. This was replaced but the car still had overheating problems. Owner replaced thermostat twice but car still overheated. Had to replace cylinder head gasket and skim the head. About four months later car overheated again, thermostat broke. Fitted another thermostat. Overheating continued. Upon inspection owner also discovered that the water pump was faulty again and had to be replaced. Engine failure resulted. Car had no oil in. No warning light to indicate this. Sub assembly was repaired in June 2019. On Friday, 16 August 2019, car made a ticking noise. Yet again no oil in car, coolant level dropped as well but still no warning lights came on.

22-8-2019: Report of 2016 Vauxhall Astra 1.6 CDTi 136 Start/Stop Elite Nav manual Estate at 13k miles going to Vauxhall dealer for clutch and brake recall. Owner objected to the emissions recall but dealer said if he didn't have the emissions software update they would not do the recall repairs. No recall repair no MoT. Whilst it was in they MoTd the car (first MoT) and it had a major fail: the steering column. They repaired this under warranty.

2-10-2019: Report of 2016 Vauxhall Astra K 1.6CDTi 136 going in for emissions update and on the way home the low level oil warning message came up on the small info screen. Driver stopped the car and dipped the engine oil, it was full. The message still comes up approx twice a journey despite the engine oil being on the top mark of the dip stick. Perhaps it's really indicatiing a malfunction of the diesel post injection system that is supposed to fire off active regenerations but is instead sinking to the sump and this is a high oil warning rather than a low oil warning.

4-10-2019: Report of repeated clutch trouble with 2016 Vauxhall Astra 1.4T bought used with 28k miles in March 2019. First clutch repair within a month under 60 day warranty because it was spongy and unresponsive. Car returned to dealer 1 week later for same fault. (See Vauxhall Mokka 3-10-2019.) Then same clutch issue occurred again 3 months later and returned to owner on 30-9-2019 after which the engine malfunction light came on.

20-11-2019: Report of 2016 Vauxhall Astra 1.6 CDTi 136 Start/Stop Elite Nav 5dr Estate Manual going in to the dealer for a brake recall in August 2019. While there the deraler carried out a software undate which, after 3 miles of driving, puts up the message low oil level, service. Owner revisited the franchised dealer that installed the software. They said it was fixed, only for him to drive 3 miles down the road and it reappeared. He contacted the dealer and Vauxhall customer services about the problem, sending several photos showing the oil low screen, they have yet to come up with a fix. Owner writes, "What Vauxhall customer services seem to do when they contact you, is to give you one ring then hang up so you have no chance to answer the phone and then send an email saying we tried to contact you. My previous question was has anyone else reported this or any other problems after the software update? I have just sent them another email asking what they think I should do regarding the problem. When info shows low oil level on for example a motorway. Pull over and check level as it is an emergency? Carry on driving and pull in at a safe place? (See 22-8-2019; 2-10-2019: same thing.)

3-6-2020: Report of piston failure on 2016 Vauxhall Astra 1.4T. Car has a full dealer service history and developed an engine misfire, which the dealer thinks is due to a cracked piston.

Recalls

28-10-2017: DVLA administered TSB recall of Vauxhall Astra K 1.6CDTI which has the same basic engine as the Mercedes-Benz C200d and numerous Renaults and Nissans. Recall letter says engine has been identified as requiring a reprogramming of the Engine Control Module as it may give faulty exhaust gas temperature readings resulting in blocked DPF and EGR. The work will be done free of charge and take about 4 hours.

21-2-2018: Manufacturer recall of Astra K model fitted with 1.4T engine. Engine 1.4L (LE2) BX14XFL/T build 2016 - 2017. <<Metallic noise in engine and sporadic loss of power. Typically observed during hard acceleration with low rpm. SPI (Stochastic Pre Ignition) most commonly occurs at low speeds during a period of rapid acceleration. SPI coud be caused by droplets or particles in the combustion chamber caused by fuel and/or oil. Therefore also see TSB 3319 and recommended use of branded fuel (higher additive contrent). Short distance driving profile increases SPI risk. MORE ROBUST CALIBRATION WAS INTRODUCED WITH MY18.

22-8-2019: Report of 'clutch and brake recall' on Vauxhall Astra K.
